Use one of the methods of polynomial division to divide -9x4 + 10x³ + 7x² - 6 by (x - 1).

The indicial equation of the differential equation

2x2y′′+x(2x−1)y′+y=0 is:  The correct answer is: (r-1)(r-1/2).

The indicial equation of a differential equation is found by substituting a power series solution into the differential equation and equating the coefficients of like powers of x to zero.
In the given differential equation, 2x^2y'' + x(2x-1)y' + y = 0, we can see that the highest power of x is x^2. Therefore, we can assume a power series solution of the form y(x) = ∑(n=0)^(∞) a_nx^(n+r).
Substituting this into the differential equation and equating the coefficients of like powers of x to zero, we get:
2x^2(∑(n=0)^(∞) (n+r)(n+r-1)a_nx^(n+r-2)) + x(2x-1)(∑(n=0)^(∞) (n+r)a_nx^(n+r-1)) + ∑(n=0)^(∞) a_nx^(n+r) = 0.
Now, let's simplify this equation:
∑(n=0)^(∞) 2(n+r)(n+r-1)a_nx^(n+r) + ∑(n=0)^(∞) 2(n+r)a_nx^(n+r) - ∑(n=0)^(∞) (n+r)a_nx^(n+r-1) + ∑(n=0)^(∞) a_nx^(n+r) = 0.
Rearranging the terms and grouping them by powers of x, we get:
∑(n=0)^(∞) ((2(n+r)(n+r-1) + 2(n+r) - (n+r))a_n)x^(n+r) = 0.
Now, let's focus on the coefficient of x^(n+r). We can see that the coefficient is zero when:
2(n+r)(n+r-1) + 2(n+r) - (n+r) = 0.
Simplifying this equation, we get:
2(n+r)^2 - (n+r) = 0.
Factoring out (n+r), we get:
(n+r)(2(n+r)-1) = 0.
Therefore, the indicial equation of the given differential equation is:
(r-1)(2r-1) = 0.
This can be simplified as:
(r-1)(r-1/2) = 0.
So, the correct answer is: (r-1)(r-1/2).

The given data supports Chatterjee's doubt.Yes, Chatterjee doubt is supported by the given data because the test statistic value is greater than the critical value for the given level of significance.

Here's a detailed explanation:A survey was conducted by Chatterjee to estimate the proportion of smokers among the graduate students.According to a previous report, it was believed that 38% of them are smokers.  We will test using α = 0.02 Null Hypothesis:The proportion of smokers among the graduate students is 38% or more.H0: P ≥ 0.38 Alternative Hypothesis:The proportion of smokers among the graduate students is less than 38%.Ha: P < 0.38 We will use the normal distribution to test the hypothesis.

The sample proportion of non-smokers is:q = 1 - p = 1 - 0.38 = 0.62 Sample size n = 150 The mean of the sampling distribution is:E(P) = p = 0.38 The standard deviation of the sampling distribution is:

σp = sqrt [pq / n] =√[(0.38)(0.62) / 150] = 0.045

So, the test statistic value is:

z = (x - μ) / σp

where x is the number of non-smokers found in the sample.

z = (100 - 0.38 × 150) / 0.045 = -17.78

The critical value for α = 0.02 is -2.05 (using a standard normal table or calculator).Since the test statistic value is less than the critical value, we reject the null hypothesis. Therefore, we can conclude that the proportion of smokers among the graduate students is less than 38%.

To find the value of 0 using the Mean Value Theorem, we need a specific function or interval to work with

The Mean Value Theorem states that if a function is continuous on a closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one value c in (a, b) where the instantaneous rate of change (the derivative) equals the average rate of change (the slope of the secant line).

For the function f(x) = x²  on the interval [0, 2], we can calculate the derivative as f'(x) = 2x. Since the function is continuous and differentiable on the interval, we can apply the Mean Value Theorem. The average rate of change on the interval [0, 2] is (f(2) - f(0)) / (2 - 0) = (4 - 0) / 2 = 2.

According to the Mean Value Theorem, there exists at least one value c in (0, 2) such that f'(c) = 2. To find this value, we solve the equation f'(c) = 2, which gives 2c = 2. Solving for c, we find c = 1.

Therefore, the value of c that satisfies the Mean Value Theorem condition in this case is c = 1.

The heat added at constant volume can be calculated using the formula:

heat added at constant volume = mass * specific heat capacity * (temperature at state 3 - temperature at state 2)

To sketch the total path on a Pv, Tv, and PT diagram, we need to understand the changes in pressure, volume, and temperature of the system as it goes from state 1 to state 2 to state 3.

1. Pv diagram:
  - State 1: The piston-cylinder contains 3 kg of saturated steam with a vapor fraction of x=0.1 at 45.5 kPa. The volume occupied by the steam is determined by the pressure and the specific volume of the steam at that pressure. The point on the diagram represents state 1.
  - State 2: Heat is added at constant pressure while the piston moves outward. This increases the volume while the pressure remains constant. The vapor fraction increases to x=0.3. The path between state 1 and state 2 on the Pv diagram is a horizontal line at 45.5 kPa.
  - State 3: The piston becomes stuck and cannot move any further. Heat continues to be added at constant volume until the pressure reaches 134 kPa. The volume remains constant, so the path between state 2 and state 3 on the Pv diagram is a vertical line at 134 kPa.

2. Tv diagram:
  - State 1: The temperature of the saturated steam in state 1 can be determined using the pressure-temperature relationship for saturated steam. The point on the Tv diagram represents state 1.
  - State 2: Heat is added at constant pressure, which increases the temperature of the steam. The path between state 1 and state 2 on the Tv diagram is a horizontal line.
  - State 3: Heat continues to be added at constant volume, which further increases the temperature of the steam. The path between state 2 and state 3 on the Tv diagram is another horizontal line.

3. PT diagram:
  - State 1: The point on the PT diagram represents state 1, where the pressure is 45.5 kPa.
  - State 2: The pressure remains constant at 45.5 kPa while heat is added. The temperature and volume increase, resulting in a path that moves diagonally upwards from state 1 to state 2 on the PT diagram.
  - State 3: The pressure continues to increase to 134 kPa while the volume remains constant. The temperature also increases, resulting in a path that moves diagonally upwards from state 2 to state 3 on the PT diagram.

To calculate the vapor fraction in state 3, we need to use the steam tables or properties of the working fluid at state 3. Since the problem statement does not provide specific information about the state, we cannot accurately calculate the vapor fraction in state 3.

To calculate the net heat added to the system, we can use the equation:

Net heat added = heat added at constant pressure + heat added at constant volume

The heat added at constant pressure can be calculated using the formula:

heat added at constant pressure = mass * specific heat capacity * (temperature at state 2 - temperature at state 1)

The heat added at constant volume can be calculated using the formula:

heat added at constant volume = mass * specific heat capacity * (temperature at state 3 - temperature at state 2)

Using the specified vapour fraction and pressure values for states 1 and 2, the specific internal energy may be calculated from the steam tables. We can determine the net heat added to the system by entering the values into the algorithm.

To sketch the total path on a Pv diagram, we need to plot the initial state (state 1) at 45.5 kPa and the final state (state 2) at 134 kPa. Since the pressure is constant during heat addition, the path on the Pv diagram will be a horizontal line connecting the two states.

To sketch the total path on a Tv diagram, we need to consider the changes in pressure and vapor fraction. We know that the vapor fraction increases from x=0.1 in state 1 to x=0.3 in state 2. So, the path on the Tv diagram will be an upward-sloping line connecting the two states.

To sketch the total path on a PT diagram, we need to plot the initial state (state 1) at 45.5 kPa and the final state (state 2) at 134 kPa. Since the volume is constant during heat addition, the path on the PT diagram will be a vertical line connecting the two states.

To calculate the vapor fraction in state 3, we need to consider the fact that the piston becomes stuck and cannot move any further. This means the volume remains constant and the pressure increases. Therefore, the vapor fraction in state 3 will be the same as in state 2, which is x=0.3.

To calculate the net heat added to the system, we need to use the information given. We know that the pressure increases from 45.5 kPa to 134 kPa. Since the volume is constant during this process, we can use the formula Q = m * (u2 - u1), where Q is the net heat added, m is the mass of the steam, and (u2 - u1) is the change in specific internal energy.

The specific internal energy can be obtained from the steam tables using the given vapor fraction and pressure values for states 1 and 2. By substituting the values into the formula, we can calculate the net heat added to the system.

Slip surface length = 100 m

Cohesion = 5 kPa

Angle of internal friction = 40°

Angle that the assumed failure plane makes with respect to the horizontal

The formula for the shear strength of a soil is:

τ = c + σ'tanφ

τ = shear strength

c = cohesion

σ' = effective stress

φ = angle of internal friction

The effective stress is the difference between the total stress and the pore water pressure. In this case, the pore water pressure is assumed to be zero.

So, the shear strength of the soil is:

τ = 5 + 0 * tan40°

τ = 5 kPa

The shear stress along the assumed failure plane is equal to the weight of the soil above the failure plane. The weight of the soil can be calculated using the following formula:

W = γ *h

W = weight of the soil

γ = unit weight of the soil (18 kN/m³)

h = height of the soil above the failure plane (100 m)

So, the weight of the soil is:

W = 18 * 100

W = 1800 kN

The shear strength along the assumed failure plane must be greater than or equal to the weight of the soil above the failure plane in order for the slope to be stable.

5 kPa ≥ 1800 kN

In this question, we are required to use the Arrhenius equation to find the rate constant of a reaction with different activation energies. We need to use the given frequency factor and temperature to solve for the rate constant for each given activation energy.

Frequency factor, A = 1.5 x 1010 s-1 Activation energy, Ea1 = 56.8 kJ/mol Activation energy, Ea2 = 28.4 kJ/mol. Temperature, T = 300K

The Arrhenius equation is given as k = A e^(-Ea/RT) Where

k is the rate constant A is the frequency factor. Ea is the activation energy. R is the gas constant T is the temperature(a) If the reaction has an activation energy of 56.8 kJ/mol, what is the rate constant at 300K?

Using the given values in the Arrhenius equation, we can solve for the rate constant, k:

[tex]k = A e^(-Ea/RT)k1 = 1.5 x 1010 e^(-56800/8.314x300)k1 = 1.69 x 10^-8 s-1[/tex]

Therefore, the rate constant at 300K with an activation energy of 56.8 kJ/mol is 1.69 x 10^-8 s-1.(b) If the reaction has an activation energy of 28.4 kJ/mol, what is the rate constant at 300K?

Similarly, we can solve for the rate constant, k2, using the activation energy of 28.4 kJ/mol:

[tex]k = A e^(-Ea/RT)k2 = 1.5 x 1010 e^(-28400/8.314x300)k2 = 2.05 x 10^4 s-1[/tex]

Therefore, the rate constant at 300K with an activation energy of 28.4 kJ/mol is 2.05 x 10^4 s-1.

What is the relationship between the magnitude of the activation energy and the magnitude of the rate constant? How is this related to the rate of the reaction?

The rate constant is exponentially dependent on the magnitude of the activation energy. As the activation energy increases, the rate constant decreases exponentially, and vice versa. This means that the higher the activation energy, the slower the reaction rate and the lower the rate constant, while the lower the activation energy, the faster the reaction rate and the higher the rate constant.

Therefore, we have successfully used the Arrhenius equation to calculate the rate constants of a reaction with different activation energies.

We have also determined that the rate constant is exponentially dependent on the magnitude of the activation energy and that the higher the activation energy, the slower the reaction rate, while the lower the activation energy, the faster the reaction rate.

It will take 50 minutes for the tank to be full. At the time the tank is full, it will contain 100 lbs of concentrate.

(a) To find out when the tank will be full, we need to determine the time it takes to fill the remaining half of the tank. Initially, the tank is half full, which is 200 gallons / 2 = 100 gallons.

The concentrate enters the tank at a rate of 5 gallons per minute, while the mixture is being pumped out at a rate of 3 gallons per minute. This means that the tank is being filled at a net rate of 5 gallons per minute - 3 gallons per minute = 2 gallons per minute.

To calculate the time it takes to fill the remaining 100 gallons, we divide the remaining volume by the net filling rate:
Time = Volume / Rate
Time = 100 gallons / 2 gallons per minute
Time = 50 minutes

Therefore, it will take 50 minutes for the tank to be full.

(b) At the time the tank is full, we need to determine the amount of concentrate it contains. Since the concentrate enters the tank at a rate of 1/2 lb/gal, we can calculate the total amount of concentrate that enters the tank.

Total concentrate = Concentrate rate x Volume
Total concentrate = (1/2 lb/gal) x (200 gallons)
Total concentrate = 100 lbs

Therefore, at the time the tank is full, it will contain 100 lbs of concentrate.

The interpretation for SSE (Sum of Squares Error) in the given scenario is option :

D) The variation in yield not explained by the variation in fertilizer.

SSE is a measure of how much the actual data points deviate from the predicted values in a regression analysis. In this case, the SSE represents the unexplained variation in the yield, which means it measures the extent to which the variation in yield cannot be attributed to the variation in fertilizer.

To understand this interpretation, let's break it down step-by-step:

1. SSE is calculated by summing the squared differences between the observed yield values and the predicted yield values from the regression model.
2. If SSE is large, it indicates that the predicted values are far from the actual data points, suggesting a poor fit of the regression model.
3. In the given scenario, the SSE represents the variation in yield that is not explained by the variation in fertilizer.
4. This means that there are other factors or variables, besides fertilizer, that contribute to the variation in yield.
5. The SSE captures the unexplained or residual variation in yield, which can be caused by factors like weather conditions, pests, soil quality, or other variables that were not considered in the regression analysis.
6. Therefore, option D) The variation in yield not explained by the variation in fertilizer, is the correct interpretation for SSE in this scenario.

Managing water pressure behind retaining walls involves a combination of drainage systems, waterproofing measures, appropriate backfill material, and effective surface water management. These strategies help alleviate hydrostatic pressure and ensure the stability and longevity of the retaining wall.

The presence of a water table at the back of a retaining wall can have significant impacts on the stability and performance of the wall. When the water table rises, it exerts hydrostatic pressure against the wall, increasing the lateral force on it. This can lead to the failure of the retaining wall, causing it to tilt, crack, or even collapse.

To reduce the water pressure behind retaining walls, several options are available. One approach is to install drainage systems, such as weep holes or French drains, at the base of the wall. These drainage systems allow the water to flow through and relieve the hydrostatic pressure. Additionally, installing a waterproof membrane or coating on the wall can help prevent water infiltration and reduce the amount of water reaching the back of the wall.

Another option is the construction of a well-designed and properly compacted backfill. Using granular backfill material, such as gravel or crushed stone, with adequate compaction can improve drainage and minimize the buildup of water pressure. In some cases, the use of geotextiles or geogrids can be employed to enhance the stability of the backfill.

Furthermore, proper site grading and diversion of surface water away from the retaining wall can help minimize the amount of water reaching the back of the wall. Implementing surface drainage systems, such as swales or gutters, can redirect water away from the wall and reduce the potential for hydrostatic pressure buildup.

In summary, managing water pressure behind retaining walls involves a combination of drainage systems, waterproofing measures, appropriate backfill material, and effective surface water management. These strategies help alleviate hydrostatic pressure and ensure the stability and longevity of the retaining wall.

They should evaluate the aquifer periodically to ensure the sustainable use of the groundwater.

The community of Limpopo found that the groundwater is a valuable resource and can provide enough water to meet their needs. As the project manager, you need to evaluate the aquifer. In this article, we will discuss the calculations required to find out the discharge from the aquifer and its conclusions.

Calculation 1.1: Discharge from the aquifer can be calculated using the equation;

Q = (2πT × b × H) / ln(R/r)

Where, Q = Discharge from the well

T = Transmissivity of aquifer

b = Thickness of the aquifer

H = Hydraulic head at the well

R = Radius of influence at the well

r = Radius of the well

Given, Transmissivity (T) = 55 m²/day

Thickness of the aquifer (b) = 25 m

Drawdown (h) = 3.5 m

Radius of influence (R) = 250 m

Well radius (r) = 0.4 m

Therefore, we can substitute all the given values in the formula,

Q = (2π × 55 × 25 × 3.5) / ln(250/0.4)

Q = 1227.6 m³/day

Therefore, the discharge from the aquifer is 1227.6 m³/day.

Calculation 1.2: Using the same formula as above,

Q = (2πT × b × H) / ln(R/r)

Given, the radius of the well is increased to 0.5 m

Now, r = 0.5 m

Substituting all the given values,

Q = (2π × 55 × 25 × 3.5) / ln(250/0.5)Q = 2209.7 m³/day

Therefore, the discharge from the aquifer is 2209.7 m³/day with the well diameter of 50 cm.

Calculation 1.3: Using the same formula as above,

Q = (2πT × b × H) / ln(R/r)

Given, the drawdown (h) = 5.5 m

Substituting all the given values,

Q = (2π × 55 × 25 × 5.5) / ln(250/0.4)

Q = 1560.8 m³/day

Therefore, the discharge from the aquifer is 1560.8 m³/day with the increased drawdown of 5.5 m.

Conclusions: From the above calculations, the following conclusions can be made:• The discharge from the aquifer is directly proportional to the well diameter. When the well diameter is increased from 40 cm to 50 cm, the discharge increased from 1227.6 m³/day to 2209.7 m³/day.•

The discharge from the aquifer is inversely proportional to the drawdown. When the drawdown increased from 3.5 m to 5.5 m, the discharge decreased from 1227.6 m³/day to 1560.8 m³/day.

Advise to the Community:

Based on the above conclusions, the community of Limpopo can increase their water supply by increasing the well diameter. However, they need to be cautious while pumping out water from the aquifer as increasing the pumping rate may result in a further decrease in discharge.

Therefore, they should evaluate the aquifer periodically to ensure the sustainable use of the groundwater.

The EGL and HGL are important tools in analyzing flow systems  as they provide insight into the energy and pressure characteristics of the fluid. This information allows engineers to optimize system design, identify and address pressure losses, and ensure efficient and reliable operation.

The main purpose of using the Energy Grade Line (EGL) and the Hydraulic Grade Line (HGL) in a flow system is to analyze and understand the energy and pressure characteristics of the fluid as it moves through the  system.

The Energy Grade Line (EGL) represents the total energy of the fluid at different points in the system. It is a line that connects the elevation head, pressure head, and velocity head of the fluid. The EGL helps us visualize how the total energy of the fluid changes along the flow path.

On the other hand, the Hydraulic Grade Line (HGL) represents the pressure characteristics of the fluid as it flows through the system. It is a line that connects the elevation head and pressure head of the fluid. The HGL shows the pressure changes that occur in the system due to friction and other factors.

By analyzing the EGL and HGL, we can determine the direction and magnitude of pressure losses, identify areas of high and low pressures, and understand the overall energy distribution in the system. This information is crucial in designing and optimizing flow systems, such as pipelines or channels, to ensure efficient and reliable operation.

For example, in a water distribution system, understanding the EGL and HGL helps engineers identify areas of potential low pressure, which could lead to inadequate water supply or inefficient operation of appliances. By adjusting pipe sizes, optimizing pump placements, or removing restrictions, engineers can ensure that the EGL and HGL are within acceptable limits, thus maintaining desired pressure levels and efficient flow.

The area of pentagon ABCDE is 36.73 square units.

Given points are, A(-3, -5), B(-3, -2), C(-2, 2), D(2, -2) and E(2, -5).We know that the area of a pentagon is given by half of the product of its perimeter and apothem. Here, the apothem can be found out by finding the distance between point A and the line segment connecting B and C.

We can use the distance formula, which is given by, d = sqrt{(x2 - x1)² + (y2 - y1)²}Let's find the equation of the line segment BC by finding its slope and the y-intercept: Slope of BC, m = (y2 - y1)/(x2 - x1) = (2 + 2)/(-2 + 2) = 4/0This slope is undefined and we cannot use the slope-intercept form of the equation. Instead, we can use the general form of the equation, which is given by: ax + by + c = 0.

We can substitute point B(-3, -2) to find the value of c as: a(-3) + b(-2) + c = 0

Substituting point C(-2, 2), we get: a(-2) + b(2) + c = 0

Solving these equations simultaneously, we get c = -4, a = -2, and b = 3. Hence, the equation of line segment BC is: -2x + 3y - 4 = 0

The perpendicular distance between point A and line segment BC is given by: d

[tex]= |(-2)(-3) + 3(-5) - 4|\sqrt(-2)^2+ 3^2 = 7\sqrt{13}[/tex]

Therefore, the apothem of pentagon ABCDE is 7/√13. Let's find the distance between the vertices A and B. This is given by: [tex]\sqrt(-2 - (-3))^2 + (-2 - (-5))^2 = \sqrt{10}[/tex]

Let's find the distance between vertices B and C.

This is given by: [tex]\sqrt(-2 - (-3))^2 + (2 - (-2))^2 = \sqrt{20}[/tex]

Let's find the distance between vertices C and D. This is given by: [tex]\sqrt(2 - (-2))^2 + (2 - (-2))^2 = \sqrt{16 + 16} = 4\sqrt2[/tex]

Let's find the distance between vertices D and E. This is given by: sqrt[tex]{(2 - 2)^2 + (-5 - (-2))^2} = \sqrt{9} = 3[/tex]

Let's find the distance between vertices E and A.

This is given by: [tex]\sqrt(-3 - 2)^2 + (-5 - (-5))^2 = 5[/tex]

The perimeter of pentagon ABCDE is: [tex]P = \sqrt{10} + \sqrt{20} + 4\sqrt2 + 3 + 5 = \sqrt{10} + \sqrt{20} + 4\sqrt2 + 8[/tex]. The area of pentagon ABCDE is: [tex]A = 1/2 (P * apothem) = 1/2 (sqrt{10} + \sqrt{20} + 4\sqrt2 + 8) * 7/\sqrt13 = 36.73[/tex] (rounded to two decimal places)

Therefore, the area of pentagon ABCDE is 36.73 square units.

Answer: 25

Step-by-step explanation:

Just because it is right yk.

The real value of the tensile load is approximately 45.86 kN.

The real value of the tensile load can be determined by substituting the given values into the equation for tensile load: (x + 46) kN.

In this case, x represents the actual value of the tensile load.

To find the real value, we need to solve for x.

The given equation for tensile load is (x + 46) kN.

Since the given diameter is 35 mm and the length is 500 mm, we can use the equation for tensile strength to find the value of x.

The tensile strength equation is (x + 206) MPa.

And the equation for final length is (x + 426) mm.

By substituting the given values into the equations, we have:

(x + 206) MPa = (x + 46) kN = (x + 426) mm

To convert the units, we need to consider the conversion factors:

1 kN = 1000 N
1 MPa = 1 N/mm²

Now we can convert the units and solve for x:

(x + 206) MPa = (x + 46) kN

Converting MPa to N/mm²:

(x + 206) * 1 N/mm² = (x + 46) * 1000 N

Simplifying:

x + 206 = 1000x + 46000

Combining like terms:

999x = 45794

Solving for x:

x ≈ 45.86

Therefore, the real value of the tensile load is approximately 45.86 kN.

The quality of the water in the output stream is 0.882, which can be rounded to 3 significant figures as 0.88.

a. Phase description of inlet stream

The given state of the inlet stream can be identified using the Mollier diagram.

The inlet pressure of water is 0.5 bar, and the temperature is 200°C. It is established that water is a superheated vapor because its pressure and temperature do not correspond to the saturation state.

b. Enthalpy of inlet stream

Using the Mollier diagram, we can determine the enthalpy of the inlet stream as follows:

At the inlet state, enthalpy = 3359 kJ/kgc.

c. Quality of water in output stream

We can determine the quality of the water in the output stream using the following formula:

Quality (x) = (h2s - h1) / (h2s - h2f)

The values of h2s and h2f, the enthalpies of the saturated mixture at 2 bar, can be obtained using the Mollier chart.

h2f = 168 kJ/kgc, and h2s = 2916 kJ/kgc.

Quality (x) = (2916 - 3359) / (2916 - 168) = 0.882

Therefore, the quality of the water in the output stream is 0.882, which can be rounded to 3 significant figures as 0.88.

The mixing time in seconds for a vessel of diameter DT=2.3 m is  150 seconds.

Given:

Diameter of the vessel, DT = 2.3 m

Liquid volume, V1 = 10,000 liters

= 10 m³

Impeller diameter, D2 = 45 in

= 1.143 m

Liquid density, p = 65 lb ft⁻³

Power dissipated by impeller, P = 0.70 metric horsepower

= 0.70 × 746

= 522.2

WNTU (Number of Transfer Units) = 2.5

Determine: Mixing time, tm in seconds

We can use the following equation to calculate the mixing time in a stirred fermenter:

pVtm = 5.9D(2/3)PD₁

We can rearrange this equation as follows:

tm = (5.9D(2/3)PD₁) / (pV)

Substituting the given values of the variables, we get

tm = (5.9 × 1.143(2/3) × 522.2 × 0.45) / (65 × 10)tm

= 0.0417 hours (since power is in horsepower, we converted to watts earlier)

tm = 2.5 minutes (since we have to convert hours to minutes)

tm = 150 seconds

Therefore, the mixing time in seconds for a vessel of diameter DT = 2.3 m containing liquid volume V₁ = 10,000 liters stirred with an impeller of diameter D, = 45 in, liquid density p = 65 lb ft⁻³, and the power dissipated by the impeller P = 0.70 metric horsepower is 150 seconds.

Step 1: Divide 138 by 24:

138 = 5 * 24 + 18

Step 2: Divide 24 by 18:

24 = 1 * 18 + 6

Step 3: Divide 18 by 6:

18 = 3 * 6 + 0

At this point, the Euclidean algorithm terminates since the remainder is zero.

Next, the algorithm to express the common divisor 6 as a linear combination of 24 and 138:

Step 3: Substitute 6 from Step 2:

6 = 18 - 3 * 6

Step 2: Substitute 6 from Step 3:

6 = 18 - 3 * (24 - 1 * 18)

Simplifying, we have:

6 = 3 * 138 - 4 * 24

Therefore, The greatest common divisor (gcd) of 24 and 138 is 6, and it can be expressed as 24x + 138y,

where x = -4 and y = 1.

2.)

To prove this, we consider different cases for the value of n:

Case 1: n = 3k, where k ∈ Z

In this case, we can express p as:

p = 3(3k) + 1 = 9k + 1 = 3(3k) + 3 - 2 = 3(3k + 1) - 2

Thus, p is of the form 3m - 2.

Case 2: n = 3k + 1, where k ∈ Z

In this case, we can express p as:

p = 3(3k + 1) + 1 = 9k + 4 = 3(3k + 1) + 3 + 1 = 3(3k + 1) + 1²

Thus, p is of the form 3m + 1.

Case 3: n = 3k + 2, where k ∈ Z

In this case, we can express p as:

p = 3(3k + 2) + 1 = 9k + 7 = 3(3k + 2) + 3 + 1² + 2²

Thus, p is of the form 3m + 2.

However, if p is of the form 3m - 2 or 3m + 2, then it is divisible by 3 and therefore not a prime.

Thus, p must be of the form 3m + 1.

Since p is a prime of the form 3n + 1 and can also be expressed as 6m + 1,

where m ∈ Z, that any prime of the form 3n + 1 where n ∈ Z is also of the form 6m + 1, where m ∈ Z.

The dot product is the directional derivative of g at the given point in the specified direction. It represents the rate of change of the function along that direction.

To find the directional derivative of function g at point (1, 1) in the direction towards (2, -1), follow these steps:

1. Determine the gradient of g at the given point. The gradient is a vector that points in the direction of the steepest increase of the function. In this case, g(x, y) is a multivariable function, so the gradient can be calculated by taking the partial derivatives of g with respect to x and y:
  - ∂g/∂x = ...
  - ∂g/∂y = ...
  Compute these partial derivatives and evaluate them at the point (1, 1).

2. Construct the direction vector. The direction vector points towards the desired direction, which is (2, -1) in this case. The direction vector can be normalized to have a length of 1 to simplify calculations.

3. Calculate the dot product of the gradient vector and the normalized direction vector. The dot product is found by multiplying the corresponding components of the two vectors and then summing the results.

The new volume of the gas is 1.25 L.

To calculate the new volume of the gas when the pressure is doubled, we can use Boyle's law equation: P₁V₁ = P₂V₂. Given that the initial volume (V₁) is 2.50 L and the pressure is doubled (P₂ = 2P₁), we can substitute these values into the equation.

P₁V₁ = P₂V₂

P₁ * 2.50 L = 2P₁ * V₂

Next, we can cancel out P₁ on both sides of the equation:

2.50 L = 2V₂

To solve for V₂, we divide both sides of the equation by 2:

V₂ = 2.50 L / 2

V₂ = 1.25 L

Therefore, when the pressure of the oxygen gas is doubled, the new volume of the gas is 1.25 L.
