State any excluded values of a domain and identify the type of break in the graph at the value of x
f(x)=x+7/x-2

Answers

Answer 1

Answer:

The excluded value in the domain is x = 2 because the denominator of the rational function becomes zero at this value of x, which results in division by zero.

At x = 2, there is a vertical asymptote, which means that the graph of the function approaches positive or negative infinity as x approaches 2 from either side.

what is cylinder?

A cylinder is a three-dimensional polyhedron made up of two congruent parallel circular bases but a curving surface linking the two bases. The bases of a cylinder are all equal to its axis, which is an artificial straight line across the centre of both bases. The volume of a cylinder is the composite of its base area and length. The volume of a cylinder is computed as V = r2h, where "V" represents the volumes, "r" represents the circle of the base, and "h" is the height of the cylinder. The formula to find the volume of a cylinder is:

[tex]V = \pir^2h[/tex]

Where V is the volume, r is the radius, h is the height, and π is a constant value that approximates to 3.14.

[tex]V = 3.14 * 4^2 * 6\\V = 3.14 * 16 * 6\\V = 301.44\\V = 301 ft^3[/tex]

2. Zara stores in the United States stocks a particular type of designer denim jeans in the United States. It stores 500 pairs of jeans each month from its two suppliers. The Hong Kong supplier charges Zara $11 per pair of jeans, and the Colombian supplier charges $16 per pair (and then Zara marks them up almost 1,000%). Although the jeans from Hong Kong are less expensive, they also have more defects than those from Colombia. Based on past data, Zara estimates that 7% of the Hong Kong jeans will be defective compared to only 2% from Colombia and Zara does not want to import any more than 5% defective items. However, Zara does not want to rely on a single supplier, so it wants to order at least 20% from each supplier every month. a. Formulate a linear programming model for this problem. b. Solve the linear programming model graphically. Use either iso-line or corner point method. How many of each should Zara buy? c. How much will Zara pay for them? d. If the Hong Kong supplier were able to reduce its percentage of defective pairs of jeans from 7% to %5, what would be the effect on the solution. Solve c in a separate sheet. First copy the sheet you solved a, b and c. Then change the necessary line and re-solve.

Answers

Zara should buy 400  pairs of jeans ordered from Hong Kong and 100 pairs ordered from Colombia for a total cost of $6,000.

See below for other solutions

Formulation of the linear programming model:

Let x be the number of pairs of jeans ordered from Hong Kong and y be the number of pairs ordered from Colombia.

Objective function:

Maximize profit, C(x, y) = 11x + 16y

Subject to the following constraints:

The total number of jeans ordered cannot exceed 500: x + y ≤ 500Zara wants to order at least 20% from each supplier: x ≥ 0.2(x+y) and y ≥ 0.2(x+y)Zara does not want to import more than 5% defective items: 0.07x + 0.02y ≤ 0.05(x+y)Non-negativity constraint: x, y > 0

Graphical solution using the corner point method:

See attachment for the graph, where we have the following corner points

(x, y) = (100, 400), (300, 200), (400, 100)

By substitution, we have

C(100, 400) = 11(100) + 16(400) = 7500

C(300, 200) = 11(300) + 16(200) = 6500

C(400, 100) = 11(400) + 16(100) = 6000

The minimum cost above is $6000

So, Zara should buy 400  pairs of jeans ordered from Hong Kong and 100 pairs ordered from Colombia.

The amount paid for them

The amount paid for them is $6,000

Reducing the percentage of defective pairs

If the Hong Kong supplier were able to reduce its percentage of defective pairs of jeans from 7% to 5%, we would need to update the constraint accordingly:

0.05x + 0.02y ≤ 0.05(x+y)

The new optimal solution would be to order 425 pairs of jeans from the Hong Kong supplier and 75 pairs of jeans from the Colombian supplier, for a total cost of $5875

i.e. C(425, 75) = 11(425) + 16(75) = 5875

The average salary for a Queens College full professor is $85,900. If the average salaries is normally distributed with
standard deviation of $11,000, find the percentage of professors that make more than $75,000.

Answers

According to the question approximately 83.89% of professors make more than $75,000 calculated by forming the equation.

Explain equation?

When the roots and solutions of two equations match, they are said to be equivalent. The same number, symbols, or expression must be added to or subtracted from both the equation's two sides to produce an equivalent equation. By multiplying or dividing both sides of an equation by a nonzero number, we can also obtain an analogous equation.

This issue can be resolved using the conventional normal distribution. First, we need to standardize the value of $75,000 using the formula:

z = (x - μ) / σ

where x is indeed the value we wish to standardise, is indeed the mean, and is the deviation.

z = (75,000 - 85,900) / 11,000

z = -0.99

Next, we look up the area to the right of z = -0.99 in the standard normal distribution table or by using a calculator. The area to the left of z = -0.99 is 0.1611, so the area to the right of z = -0.99 is:

1 - 0.1611 = 0.8389

Therefore, approximately 83.89% of professors make more than $75,000.

Therefore , the solution of the given problem of percentage comes out to be 15 customers per hour make up the unit cost. 15 clients per hour, to be exact.

What precisely is a percentage?

A number or statistic that is stated as an amount of 100 is referred to as "a%" in statistics. The forms "pct," "pct," or "pc" are additionally uncommon. The common way to indicate it is with a representation "%," though. The ratio to the total sum is flat, and there are no indicators. Percentages are actually integers because they almost always add up to 100. To suggest that a number indicates a percentage, either the word "fraction" or a representation for percentage (%) must come before the number.

Here,

We must divide the overall number of customers by the number of hours in order to determine the unit rate (in customers per hour).

There are 120 total clients.

There are 8 hours in all.

Unit rate is equal to the sum of all clients times the number of hours.

=> Unit rate: 120 / 8

=>  Rate per unit: 15

Consequently, 15 customers per hour make up the unit cost. 15 clients per hour, to be exact.

Gideon took out an R150 000 loan this morning, to buy a house. The interest rate on a mortgage is 7,35%. The loan is to be repaid in equal monthly payments over 20 years. The first payment is due one month from today. How much of the second payment applies to the principal balance? (Assume that each month is equal to 1/12 of a year.)

Answers

Answer:

Step-by-step explanation:

To solve this problem, we can use the formula for calculating the fixed monthly payment on a mortgage:

P = (r * PV) / (1 - (1 + r)^(-n))

where:

P = fixed monthly payment

r = monthly interest rate (annual interest rate divided by 12)

PV = present value of the loan (loan amount)

n = total number of payments (number of years multiplied by 12)

Using the given values:

r = 0.0735 / 12 = 0.006125

PV = R150,000

n = 20 x 12 = 240

Then we can calculate the monthly payment:

P = (0.006125 * 150000) / (1 - (1 + 0.006125)^(-240)) = R1,181.91

This means that Gideon will have to pay R1,181.91 every month for 20 years to repay his loan.

To determine how much of the second payment applies to the principal balance, we need to calculate the interest and principal amounts of the first payment.

For the first payment, the interest can be calculated as:

interest1 = r * PV = 0.006125 * 150000 = R918.75

This means that the first payment consists of R918.75 in interest and the rest, R1,181.91 - R918.75 = R263.16 is principal.

To find out how much of the second payment applies to the principal balance, we need to subtract the interest and add the calculated principal amount from the first payment to the amount of the second payment:

principal2 = (P - interest1) + principal1 = (1181.91 - 918.75) + 263.16 = R525.32

Therefore, R525.32 of the second payment applies to the principal balance.

What is the arithmetic operation?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.

Let C be the total production cost and n be the number of tickets sold.

From the problem, we know that the organization had a net loss of $800 after selling 10 tickets, so we have:

10(70) - C = -800

Simplifying, we get:

C = 1500

This means that the total production cost was $1500.

The revenue from selling n tickets at $70 per ticket is given by:

R = 70n

Substituting the values of R and C, we get:

70n = 1500

Solving for n, we get:

n = 1500/70 = 21.43

Since we can't sell a fraction of a ticket, we need to round up to the nearest whole number.

Therefore, the organization needs to sell at least 22 tickets to break even.

Answers

After cutting the squares, the length of each shorter side (and the side length of each triangular quilt piece) is approximately 14√2 inches i.e. B.

What are squares?

A square is a two-dimensional shape with four straight sides that are of equal length and four right angles (90-degree angles) at the corners. It is a special case of a rectangle, where all four sides are the same length. A square can also be thought of as a special type of rhombus, where the angles are all right angles.

Now,

Since the hypotenuse of each triangle is 28 inches long, we know that this is also the longest side of the right triangle formed by the two shorter sides of the triangle. Let's call one of the shorter sides x.

Using the Pythagorean Theorem, we can find the length of the other shorter side:

c²= a² + b²

28² = x² + x²

784 = 2x²

x² = 392

x = √(392)

x=14√2 in

Therefore, the length of each shorter side (and the side length of each triangular quilt piece) is approximately 14√2 inches (rounded to two decimal places).

With 98% confidence, we can say that the population variance is between 7.36 and 71.09.

What is probability?

Probability is a branch of mathematics that deals with the study of chance or randomness in events. It is a measure of the likelihood of an event occurring, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

To construct the confidence interval for the population variance, we will use the chi-squared distribution.

First, we need to calculate the chi-squared values for the lower and upper bounds of the confidence interval using the following formulas:

χ²_L = (n - 1) * s² / χ²(α/2, n-1)

χ²_U = (n - 1) * s² / χ²(1-α/2, n-1)

where n is the sample size, s² is the sample variance, α is the level of significance, and χ²(α/2, n-1) and χ²(1-α/2, n-1) are the chi-squared values with α/2 and 1-α/2 degrees of freedom, respectively.

Substituting the given values, we get:

χ²_L = (9 - 1) * 17.3 / χ²(0.01, 8) ≈ 3.355

χ²_U = (9 - 1) * 17.3 / χ²(0.99, 8) ≈ 29.587

Next, we can use these chi-squared values to construct the confidence interval for the population variance:

(V_L, V_U) = [(n - 1) * s² / χ²_U, (n - 1) * s² / χ²_L]

Substituting the given values, we get:

(V_L, V_U) = [(9 - 1) * 17.3 / 29.587, (9 - 1) * 17.3 / 3.355]

Simplifying, we get:

(V_L, V_U) ≈ [7.36, 71.09]

Therefore, with 98% confidence, we can say that the population variance is between 7.36 and 71.09.

A dilation centered at the origin maps the point (4,6) to the point (5/2,15/4). What is the scale factor of the dilation

Answers

We may be confident that this is the correct scale factor because both equation equations yield the same value of k. As a result, the dilatation has a scale factor of 5/8 and is centered at the origin.

What is equation?

An equation is a statement in mathematics that states the equality of two expressions. An equation has two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the value "9". The purpose of equation solving is to determine which variable(s) must be changed in order for the equation to be true. Simple or complex equations, regular or nonlinear equations, and equations with one or more elements are all possible. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are employed in a variety of mathematical disciplines, including algebra, calculus, and geometry.

Let (x,y) be a point on the plane and k be the dilation scale factor centred at the origin. The image of (x,y) under dilation is thus given by (kx, ky).

The dilation is given as (4,6) to (5/2,15/4). That is to say:

[tex]k(4) = 5/2 \sk(6) = 15/4\\k = 5/8 \sk = 5/8[/tex]

The surface area of a cylinder is given by the formula SA = 2r2 + 2rh. A cylinder has a radius of 12 cm and a surface area of 1,632 cm^2 . Find the height of the cylinder.


A. 52 cm

B. 56 cm

C. 59 cm

D. 34 cm

Answers

Using the given formula for the surface area of a cylinder, we can plug in the values we know and solve for the height h:

SA = 2r^2 + 2rh

1632 = 2(12^2) + 2(12)(h)

1632 = 288 + 24h

24h = 1344

h = 56 cm

the height of the cylinder is 56 cm.

Find the speed a car will travel with a gear ratio of 3.2 with 27 inch diameter tires , 2690 RPM engine.

Answers

To find the speed of the car, we need to use the formula:

speed = (RPM * tire diameter * pi * gear ratio) / (336 * 12)

where:

RPM is the engine speed in revolutions per minute

tire diameter is the diameter of the tires in inches

pi is the mathematical constant pi (approximately 3.14)

gear ratio is the ratio of the number of teeth on the driven gear to the number of teeth on the driving gear

336 is a constant representing the number of inches per minute that a car will travel at 1 mile per hour

12 is a constant representing the number of inches in a foot

Plugging in the given values, we get:

speed = (2690 * 27 * 3.14 * 3.2) / (336 * 12)

simplifying the equation, we get:

speed = 63.8 mph (rounded to one decimal place)

Therefore, the car will travel at a speed of approximately 63.8 miles per hour

A store pays $2.50 per pound for cat liter. One cubic foot of cat liter weighs about 48 pounds. What is the selling price of cat liter in the container shown when the markup is 20%?

Answers

Answer: The selling price of cat litter in the container shown when the markup is 20% is $3.00 per pound.

Step-by-step explanation:

One cubic foot of cat litter weighs about 48 pounds, so the weight of one pound of cat litter is 1/48 cubic feet.

The store pays $2.50 per pound for cat litter, so the cost of one pound of cat litter is $2.50.

To find the selling price with a 20% markup, we add 20% of the cost to the cost.

20% of $2.50 is $0.50.

So, the selling price per pound is $2.50 + $0.50 = $3.00.

Hope this helps, and have a great day!

What is derivative?

A functiοn's varied rate οf change with respect tο an independent variable is referred tο as a derivative. When there is a variable quantity and the rate οf change is irregular, the derivative is mοst frequently utilised.

The derivative is used tο assess hοw sensitive a dependent variable is tο an independent variable (independent variable). In mathematics, a quantity's instantaneοus rate οf change with respect tο anοther is referred tο as its derivative. Investigating the fluctuating nature οf an amοunt is beneficial.

[tex]dy/dx = d/dx (e^{(-5tan(\sqrt{x}))}) = e^{(-5tan(\sqrt{x}))} * d/dx (-5tan(\sqrt{x}))[/tex]

Next, we need tο find the derivative οf -5tan(√x) using the chain rule and the prοduct rule:

d/dx (-5tan(√x)) = -5 * d/dx (tan(√x)) = -5 * sec^2(√x) * d/dx (√x)

Tο find the derivative οf √x, we use the pοwer rule:

[tex]d/dx (√x) = 1/2x^{(1/2)[/tex]

Substituting this back intο the derivative οf -5tan(√x), we have:

[tex]d/dx (-5tan(\sqrt{x})) = -5 * sec^2(\sqrt{x}) * (1/2x^{(1/2)})[/tex]

Nοw we can substitute this back intο the derivative οf y:

[tex]dy/dx = e^{(-5tan(\sqrt{x}))} * (-5 * sec^2(\sqrt{x}) * (1/2x^{(1/2)}))[/tex]

Simplifying this, we get:

dy/dx = -5/2x^(1/2) * sec^2(√x) * e^(-5tan(√x))

Therefοre, the derivative of y = [tex]e^{(-5tan(\sqrt{x}))[/tex] is [tex]* sec^2(\sqrt{x}) * e^{(-5tan(\sqrt{x}))}).[/tex]

In a restaurant, there are 5 managers, 15 servers, 10 cooks and 15 other personnel. If a person is selected at random, what is the probability that the person is either a manager or a cook?​

Answers

Answer:

0.33

Step-by-step explanation:

There are a total of 5 + 15 + 10 + 15 = 45 people in the restaurant.

The probability of selecting a manager or a cook is the sum of the probabilities of selecting a manager and selecting a cook, since these events are mutually exclusive (a person cannot be both a manager and a cook at the same time).

The probability of selecting a manager is 5/45, since there are 5 managers out of 45 people in total.

The probability of selecting a cook is 10/45, since there are 10 cooks out of 45 people in total.

Therefore, the probability of selecting either a manager or a cook is:

P(manager or cook) = P(manager) + P(cook)

P(manager or cook) = 5/45 + 10/45

P(manager or cook) = 15/45

P(manager or cook) = 1/3

So, the probability that the person selected at random is either a manager or a cook is 1/3 or approximately 0.333

Answers

According to the question the percent abundance of the medium nails in the sample is approximately 18.95%.

Explain medium?

Whenever the set of data is presented from least to largest, the median is indeed the number in the middle. For instance, since 8 is in the middle, this would represent the median value here.

To find the percent abundance of the medium nails in the sample, we first need to calculate the total number of nails in the sample:

Total number of nails = 67 + 18 + 10 = 95

Next, we can calculate the percent abundance of the medium nails using the formula:

Percent abundance = (number of medium nails / total number of nails) x 100%

Using the values from of the table as inputs, we obtain:

Percent abundance of medium nails = (18 / 95) x 100% ≈ 18.95%

As a result, the sample's average percentage of medium nails is roughly 18.95%.

Find the Perimeter of the given figure. Remember that this is a composite figure. Be sure to show your work or explain how you found your answer in question​

Answers

Answer:

Start off with the 20ft sides

20x2 =40ft

40ft + 8ft = 48ft

Now we need to find the perimeter of the half circle.

Since we know the diameter of the half circle is 8ft, we can use the following formula: Diameter x Pi = Circumference

Plug in:

8ft x 3.14159 = 25.132ft

25.132 /2 gives us the perimeter of the half circle

25.132 / 2 = 12.566

Rounded = 12.57 ft

48 ft + 12.57 ft =  60.57 feet perimeter.

The perimeter of the given solution is 76.56 feet.

We need to find the perimeter of the figure by splitting the figure into a rectangle and a semi-circle. The radius for the semi-circle is found by dividing the diameter by 2, Radius = 8 ÷ 2 = 4.

Therefore, the formula for finding the Perimeter of the given rectangle is  

P = 2( l+b )

P = 2( 20 + 8)

P = 56 feet.

now, the formula for the circumference of a semi-circle is

C = [tex]\pi[/tex]r + 2r

C = 3.14( 4) + 2 (4)

C = 20.56 feet.

Therefore, the perimeter of the given figure is

The perimeter of  the rectangle + circumference of the Semi-circle

= 56 + 20.56

= 76.56 feet

Therefore, the perimeter of the given solution is 76.56 feet.

[tex]\textsf{8.}\quad \sf \overline{AE} = 20\sqrt{3}\; meters[/tex]

Step-by-step explanation:

Side lengths and value of b

All sides of a rhombus are the same length. Therefore, for rhombus MAZE:

[tex]\sf \overline{AZ} = \overline{AM} = \overline{ZE} = \overline{EM}[/tex]

Given:

[tex]\overline{\sf AZ} =8b-4[/tex][tex]\overline{\sf AM} =5b+8[/tex]

As the sides of a rhombus are the same length, we can equate the expressions for sides AZ and AM, and solve for b:

[tex]\begin{aligned}\overline{\sf AZ}&=\overline{\sf AM}\\8b-4&=5b+8\\8b-4-5b&=5b+8-5b\\3b-4&=8\\3b-4+4&=8+4\\3b&=12\\3b \div 3&=12 \div 3\\b&=4\end{aligned}[/tex]

Therefore, the value of b is 4.

To find the length of AZ and AM, substitute the found value of b into one of the expressions:

[tex]\begin{aligned}\overline{\sf AZ}&=8b-4\\&=8(4)-4\\&=32-4\\&=28\end{aligned}[/tex]

Therefore, as AZ = AM, then AZ = 28 and AM = 28.

[tex]\hrulefill[/tex]

Perimeter

As the sides of a rhombus are equal in length, each side length is 28 meters (as found previously).

The perimeter of rhombus MAZE is the sum of its side lengths. Therefore:

[tex]\begin{aligned}\sf Perimeter\;MAZE&=\sf \overline{AZ} +\overline{AM} +\overline{ZE}+ \overline{EM}\\&=28+28+28+28\\&=112\; \sf meters\end{aligned}[/tex]

Therefore, the perimeter of rhombus MAZE is 112 meters.

[tex]\hrulefill[/tex]

Diagonals

The point of intersection of the diagonals of rhombus MAZE is point X.

As the diagonals of a rhombus are perpendicular bisectors of each other, then:

[tex]\sf \overline{AX}=\overline{EX}\quad and \quad \overline{AX}+\overline{EX}=\overline{AE}[/tex]

[tex]\sf\overline{MX}=\overline{ZX}\quad and \quad\overline{MX}+\overline{ZX}=\overline{MZ}[/tex]

Given MZ = 44 meters, and MX is half of MZ, then:

[tex]\sf \overline{MX}=\overline{ZX}=22\;meters[/tex]

As the diagonals bisect each other at 90°, m∠MXA= 90°. Therefore, ΔMXA is a right triangle with hypotenuse AM = 28 and leg MX = 22.

As we know the lengths hypotenuse AM and leg MX, we can use Pythagoras Theorem to calculate the length of the other leg, AX:

[tex]\begin{aligned}\sf \overline{AX}^2+\overline{MX}^2&=\sf \overline{AM}^2\\\sf \overline{AX}^2+22^2&=\sf 28^2\\\sf \overline{AX}^2&=\sf 28^2-22^2\\\sf \overline{AX}&=\sqrt{\sf 28^2-22^2}\\\sf \overline{AX}&=\sf 10\sqrt{3}\; meters\end{aligned}[/tex]

As the diagonals bisect each other, AX = EX. Therefore:

[tex]\sf \overline{EX}=\sf 10\sqrt{3}\; meters[/tex]

The length of diagonal AE is the sum of segments AX and EX. Therefore:

[tex]\begin{aligned}\sf \overline{AE}&=\sf \overline{AX}+\overline{EX}\\&=\sf 10\sqrt{3}+10\sqrt{3}\\&=\sf 20\sqrt{3}\; meters\end{aligned}[/tex]

Answers

The interquartile range of the number of novels written by each of Amir's 10 favorite authors is 6.

What is the interquartile range ?

In statistics, the interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide the data set into four equal parts, with the interquartile range being the difference between the upper (third) and lower (first) quartiles. The IQR represents the middle 50% of the data, and is used as a measure of spread or dispersion in a data set, particularly when the data set contains outliers.

To find the interquartile range (IQR), we need to first find the first quartile (Q1) and the third quartile (Q3).

To find Q1:

Arrange the data in order from smallest to largest: 1 3 3 4 5 7 8 10 12 23

Find the median of the lower half of the data (the first five numbers): (3+3)/2 = 3

This is the first quartile (Q1)

To find Q3:

Arrange the data in order from smallest to largest: 1 3 3 4 5 7 8 10 12 23

Find the median of the upper half of the data (the last five numbers): (8+10)/2 = 9

This is the third quartile (Q3)

Now we can calculate the IQR:

IQR = Q3 - Q1 = 9 - 3 = 6

Therefore, the interquartile range of the number of novels written by each of Amir's 10 favorite authors is 6.
