Answers

Answer 1

The composite functions  are (A + B)(x) = x² + 2x + 4. and (AB)(x) = 2x³ - x² + 10x - 5.

Evaluating the composite functions

To find (A + B)(x), we add the two functions A(x) and B(x):

(A + B)(x) = A(x) + B(x)

So, we have

= x² + 5 + 2x - 1 (substituting the given expressions for A(x) and B(x))

= x² + 2x + 4

Therefore, (A + B)(x) = x² + 2x + 4.

To find (AB)(x), we multiply the two functions A(x) and B(x):

(AB)(x) = A(x)B(x)

= (x² + 5)(2x - 1) (substituting the given expressions for A(x) and B(x))

= 2x³ - x² + 10x - 5

Therefore, (AB)(x) = 2x³ - x² + 10x - 5.

Hashem puts boxes into small vans and into large vans.
He puts 5 boxes into each small van.
He puts 25 boxes into each large van.
Hashem puts a total of 400 boxes into the vans so that
number of boxes in small vans: number of boxes in large vans = 3:5
Hashem says that less than 30% of the vans filled with boxes are large vans.
Is Hashem correct?
You must show all your working.

Answers

Let's start by using algebra to solve for the number of boxes in small and large vans.

Let x be the number of small vans and y be the number of large vans. Based on the ratio given, we know that:

- Number of boxes in small vans = 3/8 * Total number of boxes

- Number of boxes in large vans = 5/8 * Total number of boxes

Using the information provided, we can write an equation:

5x + 25y = 400

Simplifying, we get:

x + 5y = 80

Now let's use the inequality provided to determine if less than 30% of the vans filled with boxes are large vans. We know that:

- Total number of vans filled with boxes = x + y

- Less than 30% of these vans are large vans, so y/(x+y) < 0.3

Substituting x + 5y = 80, we can simplify the inequality:

y/(x+y) < 0.3

y/80 < 0.3

y < 24

So if y (the number of large vans) is less than 24, then less than 30% of the vans filled with boxes are large vans.

Now we can solve for x and y using substitution. From x + 5y = 80, we get x = 80 - 5y. Substituting into 5x + 25y = 400, we get:

5(80 - 5y) + 25y = 400

400 - 20y = 400

20y = 0

y = 0

This means that y cannot be less than 24, as y = 0 would result in no large vans at all. Therefore, Hashem's statement is incorrect, and the number of large vans must be equal to or greater than 24.

P ( rolling a composite number and the coin landing on heads and tails )

Answers

Assuming a standard six-sided die and a fair coin, the probability of rolling a composite number (any number that is not a prime number) on the die is 3/6 or 1/2, since there are three composite numbers (4, 6, 8) out of six possible outcomes (1, 2, 3, 4, 5, 6).

The probability of the coin landing on heads is 1/2, and the probability of it landing on tails is also 1/2. Therefore, the probability of both events happening together is:

P(composite number and heads and tails) = P(composite number) x P(heads) x P(tails)

P(composite number and heads and tails) = (1/2) x (1/2) x (1/2)

P(composite number and heads and tails) = 1/8

So the probability of rolling a composite number and the coin landing on heads and tails is 1/8.

c) what is the time taken for a rope of length 18 metres to complete a revolution? Answer correct to one decimal place.

Full working please <3​

Answers

we have derived the formula T = √(8R/2.5) for the time taken for a rope of length R to be rotated about a central point, made R the subject of the formula, and used the formula to calculate the length of a rope that takes 16 seconds for a single revolution and the time taken for a rope of length 18 metres to complete a revolution.

How to solve questions?

a) To make R the subject of the formula, we need to isolate it on one side of the equation. We start by rearranging the formula:

T = √(8R/2.5)

Squaring both sides of the equation, we get:

T²= 8R/2.5

Multiplying both sides by 2.5, we get:

2.5T²= 8R

Finally, dividing both sides by 8, we get:

R = 2.5T²/8

Therefore, R is given by the formula R = 2.5T²/8.

b) To find the length of rope if it takes 16 seconds for a single revolution, we can substitute T = 16 into the formula we derived in part (a):

R = 2.5T²/8 = 2.5(16)²/8 = 100

Therefore, the length of the rope is 100 metres.

c) To find the time taken for a rope of length 18 metres to complete a revolution, we can again use the formula we derived in part (a), but this time we substitute R = 18:

T = √(8R/2.5) = √(8*18/2.5) = √(115.2) ≈ 10.7 seconds

Therefore, the time taken for a rope of length 18 metres to complete a revolution is approximately 10.7 seconds, rounded to one decimal place.

In summary, we have derived the formula T = √(8R/2.5) for the time taken for a rope of length R to be rotated about a central point, made R the subject of the formula, and used the formula to calculate the length of a rope that takes 16 seconds for a single revolution and the time taken for a rope of length 18 metres to complete a revolution.

M and N are the mid point of opposite sides of a square ABCD.a point is selected randomly in the square find the probability that it lies
1. in ∆ADM
2.in ∆ADM but not ∆ADN
3neither in ∆ADM nor in ∆ADN

Answers

The probability of selecting a point

1) in ΔADN is also 1/8.

2) in ΔADM but not in ΔADN is 0.

3) lies neither in ΔADM nor in ΔADN is 3/4.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

To solve this problem, we need to use the fact that the diagonals of a square bisect each other and are perpendicular. Let's denote the midpoint of AB as P and the midpoint of BC as Q.

To find the probability that a point selected randomly in the square lies in ΔADM, we need to find the ratio of the area of ΔADM to the area of the square ABCD.

Since M is the midpoint of AD, we have DM = AM = 1/2 * AB. Similarly, since N is the midpoint of CD, we have DN = CN = 1/2 * BC.

Thus, the area of ΔADM is (1/2 * DM * AM) = (1/2 * 1/2 * AB * 1/2 * AB) = 1/8 * AB². The area of the square is AB². Therefore, the probability of selecting a point in ΔADM is (1/8 * AB²) / AB² = 1/8.

To find the probability that a point selected randomly in the square lies in ΔADM but not in ΔADN, we need to subtract the probability of selecting a point in ΔADN from the probability of selecting a point in ΔADM. Since N is the midpoint of CD, we have AN = 1/2 * AB, and therefore DN = 1/2 * BC = 1/2 * AB.

Thus, the area of ΔADN is (1/2 * DN * AN) = (1/2 * 1/2 * AB * 1/2 * AB) = 1/8 * AB², which is the same as the area of ΔADM.

Therefore, the probability of selecting a point in ΔADN is also 1/8.

The probability of selecting a point in ΔADM but not in ΔADN is (1/8 * AB²) - (1/8 * AB²) = 0.

To find the probability that a point selected randomly in the square lies neither in ΔADM nor in ΔADN, we need to subtract the probability of selecting a point in ΔADM from the probability of selecting a point in the square and then subtract the probability of selecting a point in ΔADN from that result.

The probability of selecting a point in the square is 1.

The probability of selecting a point in ΔADM is 1/8, and the probability of selecting a point in ΔADN is also 1/8.

Therefore, the probability of selecting a point that lies neither in ΔADM nor in ΔADN is 1 - (1/8 + 1/8) = 3/4.

Hence, the probability of selecting a point

1) in ΔADN is also 1/8.

2) in ΔADM but not in ΔADN is 0.

3) lies neither in ΔADM nor in ΔADN is 3/4.

What is Scatter plot ?

A scatter plot is a type of graph that is used to display the relationship between two variables. It is a visual representation of a set of data points, where each point represents the values of two variables for a single observation.

Based on the scatter plot, it appears that there is a positive correlation between the number of chin-ups and push-ups several students did. This means that as the number of chin-ups increase, the number of push-ups also tend to increase.

We can see this trend in the general upward slope of the points in the scatter plot. However, there is also a fair amount of variability in the data, as some students did more push-ups than others even when they did a similar number of chin-ups.

I need to find the general equation for the circle that passes through the given points

Answers

The general equation for a circle with center (a,b) and radius r is:

[tex](x-a)^2 + (y-b)^2 = r^2[/tex]. By substituting the values and simplifying the equation, we will get 0.

What is circle ?

In math, a circle is a closed, two-dimensional shape made up of all elements that are spaced uniformly apart from the centre. The radius of something like the circle refers to this distance. Often, the letter "O" or "" is used to represent a circle. The circle is really a fundamental geometric shape and includes a number of significant characteristics, including its radius, which is the distance it around circle, or its area, which is the volume of the circle's interior. A circle's area is equal to 2 times its radius square, and its circumference is equal to 2 times its radius.

To find the equation for the circle that passes through the points (-5,0), (0,4), and (2,4), we need to find the center (a,b) and radius r.

First, we find the midpoint of the line segment between (-5,0) and (0,4), which is:

[tex]((-5+0)/2, (0+4)/2) = (-2.5,2)[/tex]

Next, we find the midpoint of the line segment between (0,4) and (2,4), which is:

[tex]((0+2)/2, 4/2) = (1,2)[/tex]

Since the circle passes through all three points, its center must be equidistant from all three points. Using the distance formula, we can set up three equations:

[tex](-2.5 - a)^2 + (2 - b)^2 = r^2[/tex]

[tex]a^2 + (4 - b)^2 = r^2[/tex]

[tex](1 - a)^2 + (2 - b)^2 = r^2[/tex]

Simplifying the equations and setting them equal to each other, we get:

[tex](-2.5 - a)^2 + (2 - b)^2 = a^2 + (4 - b)^2 = (1 - a)^2 + (2 - b)^2[/tex]

Expanding the squares and simplifying, we get:

[tex]6a - 10 = 0[/tex]

[tex]2b - 12 = 0[/tex]

Solving for a and b, we get:

a = 5/3

b = 6

Now we can find the radius of the circle by plugging in the values of a and b into one of the equations we set up earlier:

[tex]a^2 + (4 - b)^2 = r^2[/tex]

[tex](5/3)^2 + (4 - 6)^2 = r^2[/tex]

[tex]25/9 + 4 = r^2[/tex]

[tex]r^2 = 61/9[/tex]

Therefore, the equation of the circle is:

[tex](x - 5/3)^2 + (y - 6)^2 = 61/9[/tex]

Simplifying, we get:

A player kicks a football off the ground so that if travels with a velocity of 32 miles per hour at an angle of 34° with the ground. Find the magnitude of the horizontal and vertical components.

Answers

As a result, the horizontal component of velocity has a magnitude of 11.8 m/s\ while the vertical component of velocity has a value of 8.0 m/s.

What is velocity?

The pace at which an item changes its position is described by a vector quantity called velocity. It is described as the rate at which displacement changes in relation to time The amount and direction of velocity are both present. Speed refers to the velocity's magnitude.

The football's velocity in this scenario is 32 miles per hour, or around 14.3 meters per second.

We can use trigonometry to determine the sizes of a velocity vector's horizontal and vertical components.

Vₓ = V cos (theta), where V is the magnitude of the velocity vector and theta is the angle that the velocity vector makes with the horizontal axis, gives the horizontal component of velocity.

Vy = V sin (theta), where V is the magnitude of the velocity vector and theta is the angle that the velocity vector makes with the horizontal axis, gives the vertical component of velocity.

In this instance, we are aware of the football's velocity, which is 32 miles per hour, or around 14.3 meters per second6. It makes a 34 degree 6 angle with the ground.

Therefore,

Vₓ= V cos (theta) * cos (34 degrees) = 14.3 m/s * 11.8 m/s

Vy = V sin (theta) * sin (34 degrees) = 14.3 m/s * 8.0 m/s

Answer:

V = (l)(w)(h)

Step-by-step explanation:

This is essentially volume equals length times width times height.

V: Volume

L: Length

W: Width

H: Height

This means, that to find the volume of a rectangular prism, you multiply length times width times height. This also works if you have the values of volume and 2 values from length, width, or height, because you can rearrange the equation.

the diameters of cylinders form a normal distribution with the mean of 5 cm and the standard deviation of 0.2 cm. katie ordered a cylinder from this population and the store manager told her that the cylinder she ordered is bigger than average in size. the manager specifically mentioned that her cylinder would be in the upper 10% in its size (diameter). what is the possible lowest diameter of katie's cylinder?

Answers

The possible lowest diameter of Katie's cylinder is approximately 5.26 cm.

To find the possible lowest diameter of Katie's cylinder, we'll use the concepts of normal distribution, mean, and standard deviation.
1. Recall the given information:
- Mean diameter (µ) = 5 cm
- Standard deviation (σ) = 0.2 cm
- Katie's cylinder is in the upper 10% in size (diameter).
2. Determine the z-score that corresponds to the upper 10% of the distribution:
To find the z-score for the upper 10%, you can use a z-table or a calculator with a built-in function to find the inverse of the cumulative distribution function (commonly known as the "inverse CDF" or "quantile" function). The z-score corresponding to the upper 10% is approximately 1.28.
3. Calculate the possible lowest diameter of Katie's cylinder using the z-score formula:
z = (X - µ) / σ
where:
- z is the z-score
- X is the diameter we want to find
- µ is the mean diameter
- σ is the standard deviation
4. Rearrange the formula to solve for X:
X = z * σ + µ
5. Plug in the values and solve for X:
X = (1.28 * 0.2) + 5
X = 0.256 + 5
X ≈ 5.26 cm

Razak's mother weighs, 64.8kg. If she weighs 4 times the weight of Razak, What is Razak's weight?​

Answers

Razak weighs 16.2 kg. To find Razak's weight, we need to use the information given in the problem that his mother weighs 4 times his weight.

Let's use the variable "R" to represent Razak's weight in kilograms. According to the problem, Razak's mother weighs 4 times Razak's weight, so we can write an equation:

Mother's weight = 4 * Razak's weight

64.8 = 4R

To solve for R, we can divide both sides by 4:

64.8 / 4 = R

16.2 = R

Therefore, Razak weighs 16.2 kg.

It's important to note that in solving this problem, we assumed that the weight of Razak's mother was accurately given in the problem. Additionally, we assumed that the units of measurement were in kilograms. If the problem used different units, we would need to convert them to kilograms before solving the equation.

MATCHING: Given a temperature F in degrees Fahrenheit, the expression C = 5/9(F - 32) gives the temperature in degrees Celsius. Evaluate the following Expressions and Match the correct answer to each the degrees listed. 3. F = 23 Answer 1 Choose... 5. F = -40 Answer 2 Choose... 1. F= 68 Answer 3 Choose... 2. F= 32 Answer 4 Choose... 4. F = -4 Answer 5 Choose...

Answers

The given Fahrenheit temperatures evaluated to their Celsius equivalents are: 68°F = 20°C, 32°F = 0°C, 23°F = -5°C, -4°F = -20°C, and -40°F = -40°C.

The expression C = 5/9(F - 32) is used to convert temperatures in degrees Fahrenheit to degrees Celsius. To evaluate the expression for a given Fahrenheit temperature, we simply substitute the value of F into the formula and perform the necessary calculations.

For example, when F = 68, we substitute the value of F into the formula and simplify as follows:

C = 5/9 (68 - 32)

C = 5/9 * 36

C = 20

Here are the evaluations of the given Fahrenheit temperatures in degrees Celsius using the formula C = 5/9(F - 32):

F= 68: C = 5/9(68-32) = 20

F= 32: C = 5/9(32-32) = 0

F= 23: C = 5/9(23-32) = -5

F= -4: C = 5/9(-4-32) = -20

F= -40: C = 5/9(-40-32) = -40

Matching the correct Celsius temperatures to their respective Fahrenheit temperatures:

F= 68: C = 20

F= 32: C = 0

F= 23: C = -5

F= -4: C = -20

F= -40: C = -40

or differentiable parameterization of arc-length 2 in space ( not in a plane) how would you set up the function?

Answers

The function of differentiable parameterization of arc length 2 in space is ∫√(1)² + (2t)² + (cos(t))² dt.

To set up a differentiable parameterization of arc-length 2 in space, we can use the arc-length formula:

s = ∫√(dx/dt)² + (dy/dt)² + (dz/dt)² dt

where s is the arc length, t is the parameter, and (x, y, z) is the position vector.

We want the arc length to be 2, so we can set up the following equation:

2 = ∫√(dx/dt)² + (dy/dt)² + (dz/dt)² dt

We can then choose a function for each component of the position vector, such as:

x = t

y = t²

z = sin(t)

We can now find the derivatives with respect to t:

dx/dt = 1

dy/dt = 2t

dz/dt = cos(t)

We can substitute these into the arc-length formula:

2 = ∫√(1)² + (2t)² + (cos(t))² dt

Solving this integral for t will give us the desired parameterization of arc-length 2 in space. However, this integral may not have a closed-form solution, so numerical methods may need to be used to approximate the solution.

How many square centimeters are in the total surface area
of this cylinder? Express your answer to 2 decimal places?
4.0 cm
2.5 cm

Answers

Total surface area of this cylinder, the answer is (C) 163.36 cm².

What is an area ?

The total surface area of a cylinder can be found using the formula:

surface area = 2πr² + 2πrh

where r is the radius and h is the height.

Substituting the given values, we get:

surface area = 2π(4.0)² + 2π(4.0)(2.5)

= 2π(16.0) + 2π(10.0)

= 32π + 20π

= 52π

Using the approximation 3.14 for π and rounding to 2 decimal places, we get:

surface area ≈ 52(3.14) ≈ 163.36 cm²

Therefore, the answer is (C) 163.36 cm².

What is cylinder?

A cylinder is a three-dimensional shape that has two circular bases that are parallel and congruent to each other. The sides of a cylinder are curved, and they connect the bases. A cylinder has a constant cross-sectional area throughout its height, and it is a type of prism. The height of a cylinder is the perpendicular distance between the bases.

The volume of a cylinder can be calculated using the formula V = πr²h, where r is the radius of the base and h is the height of the cylinder. The surface area of a cylinder can be calculated using the formula A = 2πr² + 2πrh, where r is the radius of the base and h is the height of the cylinder. Cylinders are commonly found in everyday objects such as cans, pipes, and containers.

A rectangle garden has one side that is 6 feet longer than the other. A lawn care company installs synthetic grass that costs $8 per square foot in the entire.

If x represents the length, in feet, of the shorter side of the garden, and y represents the total cost, in dollars, to install the synthetic grass, which equation correctly shows the relationship between x and y?

Answers

Answer:

Step-by-step explanation:

The area of the rectangle garden can be expressed as:

Area = Length × Width

Since one side is 6 feet longer than the other, we can express the length as:

Length = Width + 6

Substituting this expression for length into the area formula, we get:

Area = (Width + 6) × Width

Simplifying this expression, we get:

Area = Width² + 6Width

The cost to install synthetic grass is given as $8 per square foot, so the total cost y can be expressed as:

y = 8(Area)

Substituting the expression for area that we found earlier, we get:

y = 8(Width² + 6Width)

Simplifying this expression, we get:

y = 8Width² + 48Width

Therefore, the equation that correctly shows the relationship between x (the length of the shorter side of the garden) and y (the total cost to install synthetic grass) is:

y = 8x² + 48x

a rectangular box has a square base. if the sum of the height and the perimeter of the square base is 14 14 in, what is the maximum possible volume?

Answers

If the sum of the height and the perimeter of the square base is 14 in, the maximum possible volume is 54 in³.

Let x represent the square box's rectangular base's side length.

Suppose h is the height.

Volume V should be used.

Considering that the square base's height plus perimeter equals 14 inches.

h + 4x = 18

Subtract 4x on both side, we get

h = 18 - 4x..........(1)

The volume is given as:

V = Area × Height

V = x² × h

Substitute the value of h

V = x² × (18 - 4x)

V = 18x² - 4x³..........(2)

Differentiate the equation 2 with respect to x

dV/dx = 36x - 12x²..........(3)

For the critical numbers,

dV/dx = 0

So, 36x - 12x² = 0

x(36 - 12x) = 0

x(-12x + 36) = 0

Equating equal to 0

x = 0                      -12x + 36 = 0

x = 0                      -12x = -36

x = 0                       x = 3

Differentiate the equation 3 with respect to x

d²V/dx² = 36 - 24x

At x = 3 the value of d²V/dx² is

d²V/dx²  = 36 - 24 × 3

d²V/dx² = 36 - 72

d²V/dx² = -36 < 0

x = 3 corresponds to the maximum of the volume V according to the second derivative test.

Now from the equation 1;

[tex]V_{\text{max}}[/tex] = 18(3)² - 4(3)³

[tex]V_{\text{max}}[/tex] = 18(9) - 4(27)

[tex]V_{\text{max}}[/tex] = 162 - 108

[tex]V_{\text{max}}[/tex] = 54 in³

Section 1: Problem Statement - Finance 302John Smith is 30 years old and graduated from CSUSM some years back, with a Business degree and an emphasis in Marketing. John is currently employed as a Marketing Manager at a well-known corporation. He has progressed well in his career, with the ultimate goal of becoming the companys CEO. Johns current salary of $78,000 has increased at an average rate of 5% per year, with routine merit raises, and he expects it keep increasing. Johns firm, ABC Corporation, has a defined contribution plan (401k) plan in place. Employees are allowed to contribute up to 15% of their gross annual salary pre-tax. Unfortunately, John has not yet taken his professors advice to Save, Start Young, and Pay Yourself First. Instead, John has enjoyed his post-college, nice-salary life by leasing a new car, renting an apartment and going out to Players every weekend. Now that he has wedding plans on the horizon, John has come to the realization (with help from his fiance, Jane Doe) that its time to start saving while hes still relatively young!John expects that the lovebirds two largest future expenses will be the cost of a wedding (short-term), then later the down payment on a house (intermediate-term). The couple plans to spend $10,000 of their own money on the wedding in twelve months. They also hope to purchase a $400,000 house within 5 years. Janes parents have promised to match their 10% down payment on the house, but only if they manage to save it within 5 years. Finally, John would like to retire at age 60, since his own father died at age 59 and did not get to enjoy the fruits of his labor in retirement.

Assuming John stays continuously invested in CDs yielding 2% annual yield for the duration of each monthly deposit from the beginning month (Month 0), how much will he have to contribute to the wedding fund every month for the next 12 months?4) Jane does acknowledge that saving for a home down payment is not as big of a priority. But both future spouses agree that they should start putting money away towards the goal of $40,000 within five years.
