Answer:

179.3 square units

Step-by-step explanation:

We have to find the area of the rectangle and area of semicircle using the formula and then add the areas.

Area of rectangle:

                  length = 14 units

                   width = 10 units

          [tex]\sf \boxed{\text{\bf Area of rectangle = length * width}}[/tex]

                                             = 14 * 10

                                             = 140 square units

Area of semicircle:

                diameter of semicircle = width of the rectangle

                                                 d =  10 units

                                                 r = d ÷ 2

                                                    = 10 ÷ 2

After burning half of a cylindrical candle, the surface area is 176 square inches. The radius of the candle is 2 inches. What was the original height of the candle? Round your answer to the nearest inch

Answers

The original height of the candle was approximately 26 inches. Rounded to the nearest inch, it will be 27 inches.

Formula for the surface area of a cylinder:

S = 2πrh + 2πr^2

where S is the surface area, r is the radius, and h is the height.

The radius is 2 inches and that the surface area after burning half the candle is 176 square inches. Substitute this values in the equation for surface area:

176 = 2π(2)(h/2) + 2π(2)^2

Simplifying:

176 = 2πh + 8π

168 = 2πh

h = 168/(2π)

h ≈ 26.75

So the original height of the candle was approximately 26 inches. Rounded to the nearest inch, the original height is 27 inches.

what is exponent ?

In mathematics, an exponent (also known as a power or index) is a number that indicates how many times a given number (the base) must be multiplied by itself.

In the given question,

The given exponential model is:

y = 200(0.80)ˣ

where:

y is the output (dependent variable)

x is the input (independent variable)

To determine whether the model represents exponential growth or decay, we need to examine the base of the exponent, which is 0.80 in this case.

If the base is greater than 1, then the model represents exponential growth, and if the base is between 0 and 1, then the model represents exponential decay.

In this case, the base of the exponent is 0.80, which is between 0 and 1. Therefore, the model represents exponential decay.

The growth/decay factor is the base of the exponent, which is 0.80 in this case. The factor is less than 1, indicating that the output (y) decreases as the input (x) increases. The factor represents the rate of decay per unit of the independent variable, which in this case is 0.80.

Brian deposited $9,083 into a savings account for which interest is compounded quarterly at a rate of 2.90%. How much interest will he earn after 6 years? Round answer to the hundredths place. If answer does not have a hundredths place then include zeros so it does. Do not include units in the answer. Be sure to attach your work for credit.

Answers

Using the compound interest formula, the interest Brian will earn after 6 years is: $2,347.22.

How to Calculate Compound Interest?

We can use the formula for compound interest to calculate the interest earned by Brian:

A = P (1 + r/n)^(nt)

where:

A = the amount after t years

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time in years

In this case, P = $9,083, r = 2.90% or 0.029, n = 4 (since interest is compounded quarterly), and t = 6.

So,

A = 9083(1 + 0.029/4)^(4*6)

= $11,430.22

The interest earned will be the difference between the amount after 6 years and the initial investment:

Interest = A - P = $11,430.22 - $9,083 = $2,347.22

Therefore, Brian will earn $2,347.22 in interest after 6 years.

Find the indicated probability using the two/way table: p(drive to school | senior)

Answers

The probability that a senior drives to school is 0.3 or 30%.

To find the indicated probability using the two-way table, we need to locate the row for "senior" and the column for "drive to school" and then find the corresponding cell.

Let's assume that the two-way table shows the number of students who either drive or take the bus to school based on their grade level. We are interested in finding the probability that a student drives to school given that they are a senior.

So, we locate the row for "senior" and the column for "drive to school". Let's say that the cell in the intersection of these two is labeled "30". This means that there are 30 seniors who drive to school.

Next, we need to find the total number of seniors in the sample. Let's say that the total number of seniors in the sample is 100.

To find the probability that a senior drives to school, we divide the number of seniors who drive to school by the total number of seniors in the sample:

P(drive to school | senior) = 30/100 = 0.3 or 30%

Therefore, the probability that a senior drives to school is 0.3 or 30%.

indicated that the population standard deviation was $17. 50.


Use this information to create a 95 percent confidence interval for the population mean.

Answers

The 95 percent confidence interval for the population mean is $65.59 to $74.41.

To calculate a 95% confidence interval for the population mean, we will use the sample mean, population standard deviation, and sample size provided. The formula for the confidence interval is:

CI = X ± (Z * (σ / √n))

Where:
- X is the sample mean, $70.00
- Z is the Z-score for a 95% confidence interval, 1.96
- σ is the population standard deviation, $17.50
- n is the sample size, 60

CI = $70.00 ± (1.96 * ($17.50 / √60))

Calculate the margin of error:

Margin of Error = 1.96 * ($17.50 / √60) ≈ $4.41

Now, calculate the confidence interval:

Lower Limit = $70.00 - $4.41 ≈ $65.59
Upper Limit = $70.00 + $4.41 ≈ $74.41

So, the 95% confidence interval for the population mean is approximately $65.59 to $74.41.

Thank you

Answers

Answer:

x = 15

I think thats what u wanted me to do- I hope it helps though. Middle school is hard.

Step-by-step explanation:

2x/3 + x/5 = 13

Here, we have to two different denominators in the LHS. So in order to solve the equation, we need to have like denominators and hence we find the Least Common Multiple (LCM).

The LCM of the denominators 3 and 5 is 15. Hence, we multiply each term to bring the denominator to 15.

5.(2x/3) + 3.(x/5) = 13

Now we combine the fractions with common denominator.

10x/15 + 3x/15 = 13

(10x + 3x)/15 =13

13x/15 = 13

Now, multiply the numbers and solve

13x = 13 . 15

x = 15 (cancelling 13 from both LHS and RHS)

Answers

Answer:

Step-by-step explanation:

To plot the given rational function f(x) = (5x+20)/(x^2 - 20), we need to find the vertical asymptote, horizontal asymptote, x-intercepts, y-intercepts, and holes.

Vertical asymptote:

The denominator of the rational function cannot be zero. Therefore, we need to find the value of x when the denominator equals zero.

x^2 - 20 = 0

x^2 = 20

x = ±√20

The vertical asymptotes are x = √20 and x = -√20.

Horizontal asymptote:

To find the horizontal asymptote, we need to compare the degree of the numerator and denominator. The degree of the numerator is 1, and the degree of the denominator is 2. Therefore, the horizontal asymptote is

y = 0.

X-intercepts and y-intercept:

To find the x-intercepts, we need to set the numerator equal to zero.

5x + 20 = 0

x = -4

Therefore, the x-intercept is (-4,0).

To find the y-intercept, we need to set x equal to zero.

f(0) = (5(0) + 20) / (0^2 - 20)

f(0) = -1

Therefore, the y-intercept is (0,-1).

Hole:

We can factor the numerator and denominator of the rational function to find if there is a hole. Factoring 5x + 20, we get 5(x+4). Therefore, there is a hole at x = -4.

To summarize, the features of the rational function f(x) = (5x+20)/(x^2 - 20) are:

Vertical asymptotes at x = √20 and x = -√20

Horizontal asymptote at y = 0

X-intercept at (-4,0)

Y-intercept at (0,-1)

Hole at x = -4

location a receives five small vans and two large vans for
a total cost of $72,500. location b receives two small
vans and six large vans for a total cost of $107,000.
what is the cost of each type of van?
cost of small vans (x)
cost of large vans (y)

Answers

After solving the cost function, the cost of each small van is $8,500 and the cost of each large van is $15,000.

Let's use the variables x and y to represent the cost of a small van and a large van, respectively.

From the information given, we can set up a system of two equations:

5x + 2y = 72500

2x + 6y = 107000

We can solve for x and y by using any method of linear equations, such as substitution or elimination. Here, we'll use elimination:

Multiplying the first equation by 3 and the second equation by -1, we get:

15x + 6y = 217500

-2x - 6y = -107000

Adding these two equations, we eliminate the y variable:

13x = 110500

Dividing both sides by 13, we get:

x = 8500

Now we can use this value to find y:

5x + 2y = 72500

5(8500) + 2y = 72500

42500 + 2y = 72500

2y = 30000

y = 15000

Therefore, the cost of each small van is $8,500 and the cost of each large van is $15,000.

Answers

The monthly installment of the air conditioner is $ 21 and the total amount paid for the air conditioner is $ 1188. She has to pay $ 288 more for buying the air conditioner on hire purchase.

Original cost = $900

Downpayment = 20%

Downpayment = 20% of 90

For simple interest,

A = P + P * r * t

where A is the amount

P is the principal

r is the rate of interest

t is the time

Given,

P = Total cost - Downpayment

= 900 - 180

Consider the following.
u = -8i - 4j - 2k, v = 2j + 2k
Find the projection of u onto v.
Find the vector component of u orthogonal to v

Answers

To find the projection of u onto v, we need to use the formula:

projv(u) = (u · v / |v|^2) * v

where u · v is the dot product of u and v, and |v|^2 is the magnitude of v squared.

First, we calculate u · v:

u · v = (-8i - 4j - 2k) · (0i + 2j + 2k) = 0 + (-8*0) + (-4*2) + (-2*2) = -8

Next, we calculate |v|^2:

|v|^2 = (2)^2 + (2)^2 = 8

Now, we can plug these values into the projection formula:

projv(u) = (-8 / 8) * (2j + 2k) = -1j - 1k

So the projection of u onto v is -1j - 1k.

To find the vector component of u orthogonal to v, we can use the formula:

u - projv(u)

We already found projv(u) to be -1j - 1k, so we just need to subtract that from u:

u - projv(u) = (-8i - 4j - 2k) - (-1j - 1k) = -8i - 3j - k

Therefore, the vector component of u orthogonal to v is -8i - 3j - k.
To find the projection of u onto v, we will use the formula:

proj_v(u) = (u•v / ||v||^2) * v

where u = -8i - 4j - 2k, v = 2j + 2k, and • denotes the dot product.

First, calculate the dot product (u•v):

u•v = (-8)(0) + (-4)(2) + (-2)(2) = -8 - 4 = -12

Next, calculate the magnitude squared of v (||v||^2):

||v||^2 = (0^2) + (2^2) + (2^2) = 0 + 4 + 4 = 8

Now, use the formula:

proj_v(u) = (-12 / 8) * v = -1.5 * (2j + 2k) = -3j - 3k

Next, to find the vector component of u orthogonal to v, use the formula:

u_orthogonal = u - proj_v(u)

u_orthogonal = (-8i - 4j - 2k) - (-3j - 3k) = -8i - 1j + 1k

So, the projection of u onto v is -3j - 3k, and the vector component of u orthogonal to v is -8i - 1j + 1k.

(1 point) Estimate I = S." (+2) + dx using n = 4 subintervals and (a) Left endpoints. I (b) Right endpoints. IM

Answers

To estimate I = S." (+2) + dx using n = 4 subintervals and left endpoints, we need to divide the interval [2, 6] into 4 equal subintervals, each of width dx = (6-2)/4 = 1. Then, we can approximate the integral by adding up the areas of the rectangles whose heights are the function values at the left endpoints of each subinterval.

(a) Using left endpoints, the approximation of the integral is:

I ≈ sum from i=0 to 3 of f(2+i*dx)*dx
 = f(2)*dx + f(3)*dx + f(4)*dx + f(5)*dx
 = f(2)*1 + f(3)*1 + f(4)*1 + f(5)*1

(b) Using right endpoints, the approximation of the integral is:

I ≈ sum from i=1 to 4 of f(2+i*dx)*dx
 = f(3)*dx + f(4)*dx + f(5)*dx + f(6)*dx
 = f(3)*1 + f(4)*1 + f(5)*1 + f(6)*1

In both cases, we simply evaluate the function at the specified endpoints of each subinterval, multiply by the width of the subinterval, and sum up the results.

Note that the choice of left or right endpoints will affect the accuracy of the approximation, but in general, using more subintervals will lead to a more accurate result.
(a) Left Endpoints:

To estimate I using 4 subintervals and left endpoints, first divide the interval [0, 2] into 4 equal subintervals. Each subinterval has width Δx = (2 - 0) / 4 = 0.5. The left endpoints of these subintervals are x = 0, 0.5, 1, and 1.5. The integral estimate is:

I ≈ Δx[f(0) + f(0.5) + f(1) + f(1.5)]

Evaluate the function at these points, and then multiply the sum by Δx.

(b) Right Endpoints:

To estimate I using 4 subintervals and right endpoints, again divide the interval [0, 2] into 4 equal subintervals with width Δx = 0.5. The right endpoints of these subintervals are x = 0.5, 1, 1.5, and 2. The integral estimate is:

I ≈ Δx[f(0.5) + f(1) + f(1.5) + f(2)]

Evaluate the function at these points, and then multiply the sum by Δx.

Write five rational numbers between :-
1) -1/5 and 1/5
2)1/10 and 3/10
3)2/7 and 3/5

Answers

The five rational numbers between  -1/5 and 1/5 are:-1/6, -1/10, 0, 1/10 and 1/6

2) The five rational numbers between 1/10 and 3/10 are:  1/10, 3/30, 5/30, 7/30, and 9/30

3) the five rational numbers between 2/7 and 3/5 are 1/5, 12/35, 13/35, 2/5, and 3/7.

What is the rational numbers?

To find the five rational numbers between -1/5 and 1/5, we need to see the common difference between these numbers.

The difference between the two fractions is 1/5 - (-1/5)

                                                                             = 2/5.

To find the common difference between the five fractions, we divide 2/5 by 6 so it will be

2/5 ÷ 6

= 1/15

So we need to begin with -1/5 and add 1/15 repeatedly to get the five fractions:

-1/5 + 1/15 = -1/6

-1/6 + 1/15 = -1/10

-1/10 + 1/15 = 0

0 + 1/15 = 1/10

1/10 + 1/15 = 1/6

2. To find the five rational numbers between 1/10 and 3/10, the difference between the two fractions is"

3/10 - 1/10 = 2/10 = 1/5.

So we divide 1/5 by 4

1/5 ÷ 4 = 1/20

Hence:

1/10 + 1/20 = 1/10

1/10 + 2/20 = 3/30

1/10 + 3/20 = 5/30

1/10 + 4/20 = 7/30

1/10 + 5/20 = 9/30 = 3/10

3. One need to find a common denominator for 2/7 and 3/5, which is 35.

Convert both fractions to have a denominator of 35:

2/7 = 10/35

3/5 = 21/35

So to get the rational number, it will be:

10/35 + 1/35  =11/35   = 1/5 10/35 + 2/35  = 12/35 10/35 + 3/35 == 13/3510/35 + 4/35 = 14/35 = 2/5 10/35 + 5/35 = 15/35 = 3/7

MAGIC SHOW A magician currently sells tickets to his shows for $15 and averages 180 spectators per show. He estimates that he can sell 10 more tickets for each $0.75 decrease in price. a. Let x represent the number of $0.75 price decreases. Write a function P(x) to represent the price of a ticket and a function T(x) to represent the number of tickets sold. b. Write a function R(x) that can be used to find the revenue from ticket sales. c. If the magician decides to sell the tickets for $12, find his revenue. m

Answers

On the basis of given data & Using combining-functions, We can say that

a).The function P(x) which represents the price of a ticket can we given by where x represents the number of 0.75 price decreases= ($15 - 0.75x)

b). the function T(x) which represents number of tickets sold on a day

=(180 + 10x)

c). the revenue would be if the magician decides to sell the tickets for

$12 =  $ 2640

What are combining-functions?

The process of composition, in which the result of one function becomes the input of another, allows us to create complex functions from basic ones. A complicated function may occasionally need to be broken down into two or more simpler ones, using the opposite method.

Given that:

Current price of ticket = $15

Average tickets sold per day = 180

Price decrease each time = $0.75

Number of price decreases = x

Total Price decrease = 0.75x

Increase in number of tickets with price decrease each time = 10

Total increase in number of tickets with x times price decrease = 10x

a). Function to represent total price of tickets

P(x) = current price - total price decrease  

      = ($15 - 0.75x)

Function to represent number of tickets T(x)

= average number of tickets+ total increase in tickets

= (180 + 10x)

b)Function to represent total revenue R(x) = total tickets x total price

                                                                      = T(x) . P(x)

                                                                      = (180 + 10x) ($15 - 0.75x)

c)Given that total price of tickets=$12

                                            P(x)=$12

                             ($15 - 0.75x) = $12

                                      - 0.75x  =  $12 - $15

                                       - 0.75x  =  - $3

                                              x = 3 ÷ 0.75

                                              x = 4 times

The number of times price decreased=4

Total tickets sold T(x) =(180 + 10x)

                                  =(180 + 10(4))

                                  =180+40

                                   =220 tickets

Total revenue= T(x) . P(x)

                    = 220 x 12

                    =$2640

Total revenue earned on 220 tickets at $12 is $ 2640

The slant height if the cone is 26 cm. what is the volume of a cone having a radius of 10 cm and a slant height of 26 cm.

Answers

Therefore, the volume of the cone is approximately 800π cubic centimeters, or approximately 2512.44 cubic centimeters when rounded to two decimal places.

What is volume?

Volume is a measure of the amount of space occupied by a three-dimensional object or a substance. The volume of a solid object can be determined by measuring its dimensions, such as its length, width, and height, and applying an appropriate mathematical formula depending on its shape.

Here,

The volume of a cone can be calculated using the formula:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is a constant equal to approximately 3.14. In this case, we are given the radius of the cone as 10 cm and the slant height as 26 cm. We can use the Pythagorean theorem to find the height of the cone:

h² = (slant height)² - (radius)²

h² = 26² - 10²

h² = 576

h = √576

h = 24

Now that we have the height of the cone, we can use the formula for the volume of a cone:

V = (1/3)πr²h

V = (1/3)π(10²)(24)

V = (1/3)π(100)(24)

V = (1/3)(2400π)

V = 800π
