Answers

Answer 1

The instantaneous rate of change in revenue at x=14 is $860 per camera.

The average change in revenue is $85 per camera [(ΔR/Δx) = 255/3].

a. The average change in revenue if production is changed from x=14 to x=17 is equal to the average rate of change of the revenue function over this interval:

Δx = 17 - 14 = 3

ΔR = R(17) - R(14) = (100017 - 517^2) - (100014 - 514^2) = $255

Therefore, the average change in revenue is $85 per camera [(ΔR/Δx) = 255/3].

b. The instantaneous rate of change in revenue at x=14 is equal to the derivative of the revenue function evaluated at x=14:

R(x) = 1000x - 5x^2

R'(x) = 1000 - 10x

R'(14) = 1000 - 10(14) = $860

Therefore, the instantaneous rate of change in revenue at x=14 is $860 per camera.

1. The area of square C is 625 ft². 2. The perimeter of square C is 46 ft. 3. The area of square B is 1456 ft². 4. The length of square A is 4√15 ft.

What is Pythagoras theorem?

A key idea in geometry that connects the lengths of a right triangle's sides is known as the Pythagorean Theorem. It says that the hypotenuse's square length, which is the side that faces the right angle, is equal to the sum of the squares of the lengths of the other two sides in a right triangle. It has the following mathematical expression:

a² + b² = c²

1. The area of square C can be found using the Pythagorean Theorem:

a² + b² = c²

Using the area the side is calculates as follows:

Side length of A = √225 = 15 ft

Side length of B = √400 = 20 ft

Now,

15² + 20² = c²

225 + 400 = c²

625 = c²

c = √625 = 25 ft

So the area of square C is:

Area of C = 25² = 625 ft²

2. The perimeter of square C can be found by adding up the side lengths of all three squares:

Perimeter of A = 36 ft, so each side length of A is 9 ft.

Perimeter of B = 48 ft, so each side length of B is 12 ft.

Perimeter of C = Side length of A + Side length of B + Side length of C

Perimeter of C = 9 + 12 + c

We found earlier that c = 25 ft, so we can substitute that in:

Perimeter of C = 9 + 12 + 25 = 46 ft

3. The area of square B can be found using the fact that the areas of squares A, B, and C are related by the equation:

Area of A + Area of B = Area of C

We know the area of A and the area of C, so we can solve for the area of B:

Area of A = 15² = 225 ft²

Area of C = 1681 ft²

Area of A + Area of B = Area of C

225 + Area of B = 1681

Area of B = 1456 ft²

4. Perimeter of B = 64 ft

Side length of B = 64 / 4 = 16 ft

Now we can use the Pythagorean Theorem to find the side length of C:

a² + b² = c²

a = 15 ft (side length of A)

b = 16 ft (side length of B)

c = √(a² + b²) = √(15² + 16²) = √481 = 22 ft

Finally, we can use the Pythagorean Theorem again to find the side length of A:

a² + b² = c²

b = 16 ft (side length of B)

c = 22 ft (side length of C)

a = √(c² - b²) = √(22² - 16²) = √240 = 4√15 ft

16 students at a school were asked about their favorite pasta dish. A graph of the results is on the left.
Create a bar graph showing the possible results for all 400 students in the school. Be sure to number the vertical axis.

Answers

Answer:

Step-by-step explanation:

to solve this question, we need to use the graph on the left to find the proportions of students who prefer each pasta dish, and then multiply those proportions by 400 to get the estimated number of students in the whole school who prefer each pasta dish. Then we need to plot those numbers on a bar graph with the pasta dishes on the horizontal axis and the number of students on the vertical axis. The graph below shows one possible way to create the bar graph:

We can see that the vertical axis is numbered from 0 to 120 in increments of 20. The bars show the estimated number of students who prefer each pasta dish, based on the sample of 16 students. For example, since 4 out of 16 students prefer spaghetti, we can estimate that 4/16 x 400 = 100 students in the whole school prefer spaghetti. Similarly, since 3 out of 16 students prefer lasagna, we can estimate that 3/16 x 400 = 75 students in the whole school prefer lasagna. We can repeat this process for the other pasta dishes and plot them on the graph.

Problem 3: enter the value of c when the expression 12.2x + c is
equivalent to 6.1(2x - 3.4).

Answers

The value of c that makes the two expressions equivalent is -20.74.

Let's start by simplifying the expression 6.1(2x - 3.4). To do this, we use the distributive property of multiplication, which states that a(b + c) = ab + ac. Applying this to our expression, we get:

6.1(2x - 3.4) = 6.1(2x) - 6.1(3.4) = 12.2x - 20.74

Now we can rewrite the equation we want to solve as:

12.2x + c = 12.2x - 20.74

To solve for c, we need to isolate it on one side of the equation. We can do this by subtracting 12.2x from both sides:

Wesley makes spherical fish tanks with a diameter of 30cm. Kate requests a smaller tank with half the volume of the tank that Wesley usually makes. Kate tried to figure out the approximate diameter of the smaller tank, but she made a mistake. In which step did Kate first make her mistake?

Answers

Kate's mistake was in Step 2: "Divide the volume of Wesley's tank by 2." Since she wants a tank with half the volume of Wesley's tank, she should have divided the volume of Wesley's tank by 2, not the radius.

How to determine  which step did Kate first make her mistake

The correct approach would be to use the formula for the volume of a sphere:

V = (4/3)πr^3

Since Wesley's tank has a diameter of 30 cm, its radius is 15 cm. Substituting this value into the formula gives:

V = (4/3)π(15)^3

V ≈ 14,137 cm^3

To find the radius of the smaller tank with half the volume, Kate should have solved for the radius using the formula for the volume of a sphere:

(4/3)πr^3 = (1/2)(4/3)π(15)^3

Simplifying this equation gives:

r^3 = (1/2)(15)^3

r ≈ 10.8 cm

Therefore, the approximate diameter of the smaller tank should be 21.6 cm (twice the radius), not 10.8 cm.

takes the loan for 5 years? *

Answers

Tabitha could pay $4,408.29 less for her SUV if she takes the loan for five years in place of 7.

To calculate the total amount Tabitha might pay for the SUV with a 7-year loan, we are able to use the compound interest formula for calculating the total amount of a loan, that is:

[tex]total amount = principal x (1 + interest charge)^{time}[/tex]

Wherein:

principal is the amount of the loaninterest charge is the annual interest rate Time is the length of the loan in years

With a 7-year loan, the full amount Tabitha could pay is:

[tex]total amount = $29,000 x (1 + 0.043)^{7} = $37,501.76[/tex]

To calculate the overall amount she could pay with a 5-year loan and a 5% decrease interest rate, we first need to calculate the new interest price. A 5% discount inside the interest price of 4.3% is:

New interest price = 4.3% - 5% = 3.3%

Then we can use the equal formula as before to calculate the total amount with the 5-year mortgage:

[tex]total amount = $29,000 x (1 + 0.033)^{5} = $33,093.47[/tex]

The difference in the overall amount among the two loans is:

$37,501.76 - $33,093.47 = $4,408.29

Therefore, Tabitha could pay $4,408.29 less for her SUV if she takes the loan for five years in place of 7.

Answers

The value of y is 116°.

Three given Adjacent angles are 28°, 36° and y°.

When two angles are adjacent, they have a common side between them and share a common vertex where the two sides meet. The angles are said to be adjacent because they are next to each other.

We know that if a ray stands on a straight line, then the sum of adjacent angles is 180°.

So, 28° + y° + 36° = 180°

y° + 64° = 180°

annually. She started at the same price at the second bank, however the


interest rate was 4. 2% compounded continuously. Set up an equation to show


the total amount.

Answers

To set up an equation to show the total amount, we can use the formula for compound interest:

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

Where:


A = the total amount
P = the principal (initial investment)
r = the interest rate
n = the number of times the interest is compounded per year
t = the time period (in years)

For the investment at Citibank:


P = $400
r = 3%
n = 1 (compounded annually)
t = 1 (since it is compounded annually)

So, the equation would be:

A1 = $400(1 + 0.03/1)^(1*1)
A1 = $412

For the investment at the second bank:


P = $400
r = 4.2%
n = ∞ (compounded continuously)
t = 1 (since it is for 1 year)

So, the equation would be:

A2 = $400e^(0.042*1)
A2 = $416.99

To find the total amount, we can add the two amounts together:

Total amount = A1 + A2
Total amount = $412 + $416.99
Total amount = $828.99

Therefore, Talissa's total amount after one year with the two investments is $828.99.

Basically, you will find the circumference of the entire circle and then using that find the length of the arc.

So the circumference of the circle is its radius (11) times pi multiplied by 2.

2(11 x 3.14) = 69.08

Now a circle is always 360 degrees and the angle of the sector is 60 degrees.

So we have our circumference and we only need that small portion, so you take and make it a fraction and multiply by the circumference to find the length of that small portion:

2. Yes, battery life is a function of time. The longer a battery is in use, the more its charge will deplete. However, it is not necessarily a linear function as the rate of battery drain can vary depending on factors such as usage patterns, app activity, and temperature. In this specific case, it appears that the rate of battery drain may be slowing down as the percentage decrease from 90% to noon is less than the decrease from fully charged to 90%.

The characteristic property of linear functions is that when the input variable is changed, the change in the output is proportional to the change in the input.

Linear functions are related to linear equations.

You are shopping for a King & Queen size mattress, each of which are shaped like a rectangle. The Queen is 16 inches longer than it is wide. The King is 20 inches wider than the Queen, but has the same length. The area of the King-sized mattress is 1,600 in² larger than the Queen. Find the Area of both mattresses

Answers

The area of the King-sized mattress is 4,800 square inches and the area of the Queen-sized mattress is 3,200 square inches.

To find the dimensions of the Queen-sized mattress, let x be the width. Then, the length of the mattress is x + 16. The area of the Queen-sized mattress is x(x + 16) = x² + 16x.

Since the King-sized mattress has the same length as the Queen-sized mattress, its length is x + 16. Also, its width is 20 inches wider than the Queen-sized mattress, so its width is x + 16 + 20 = x + 36. Therefore, the area of the King-sized mattress is (x + 16)(x + 36) = x² + 52x + 576.

The area of the King-sized mattress is 1,600 square inches larger than the area of the Queen-sized mattress. So, we can set up the following equation:

x² + 52x + 576 - (x² + 16x) = 1600

Simplifying this equation, we get:

36x + 576 = 1600

36x = 1024

x = 28

Therefore, the width of the Queen-sized mattress is 28 inches and the length is 44 inches. So, its area is 3,200 square inches.

The width of the King-sized mattress is 28 + 36 = 64 inches and the length is 44 inches. So, its area is 4,800 square inches.

For the function f(x) = x^2e^7x find the critical numbers and use the First Derivative Test to find the local
maximum and minimum values and where they occur. Enter exact answers in fraction form.

Answers

For the function f(x) = x^2e^7x the critical numbers are 0 and -2/7 and using the First Derivative Test local minima at x = 0 and -2/7.

The function f(x) = x²e⁷ˣ

Differentiate the function f(x) with respect to x

f'(x) = 2xe⁷ˣ + 7x²e⁷ˣ

f'(x) = xe⁷ˣ(2 + 7x)

Now put f'(x) = 0 for critical points.

xe⁷ˣ(2 + 7x) = 0

x = 0                 2 + 7x = 0              e⁷ˣ ≠ 0

x = 0                 x = -2/7                e⁷ˣ ≠ 0

Hence, 0 and -2/7 are the critical points.

f'(x) = 2xe⁷ˣ + 14x²e⁷ˣ

Now f''(x) = 2e⁷ˣ + 14xe⁷ˣ + 28xe⁷ˣ + 98x²e⁷ˣ

f''(x) = 2e⁷ˣ + 42xe⁷ˣ + 98x²e⁷ˣ

f''(x) = 2e⁷ˣ(1 + 21x + 49x²)

Now f''(x) at x = 0

f''(0) = 2e⁷⁽⁰⁾(1 + 21(0) + 49(0)²)

f''(0) = 2(1 + 0 + 0)

f''(0) = 2 > 0

So f(x) has minima at x = 0

Local minima at x = 0 and y = 0.

Now f''(x) at x = -2/7

f''(0) = 2e⁻²(1 + 21(-2/7) + 49(-2/7)²)

f''(0) = 2e⁻²(1 - 6 + 4)

f''(0) = -2e⁻² < 0

f(x) has local minima at x = -2/7

Now y at x = -2/7 is

y = f(-2/7)

y = (-2/7)² e⁻²

y = 4/49e²

What is the area of triangle hgf? round your answer to the nearest tenth of a square centimeter. recall that you need to
round up if the value of the hundredth is 5 or greater.

Answers

The area of triangle HGF is 9.8 cm²

The Sides of the given triangle are 6.5 cm, 3.6 cm and 5.6 cm

We know that the area of the triangle is the half of product of base and height of the triangle.

The base of the triangle = 6.5 cm

Height of the triangle = 3.0 cm

We know that the triangle is

Area = 1/2 × base × height

= 1/2 × HF × GE

= 1/2 × 6.5 × 3.0

= 1/2 × 19.5

= 9.75

Five students are going to volunteer at a food pantry tomorrow. Each student will be assigned to either the morning shift or the afternoon shift, but not both. Each shift must be covered by at least two of the five students. How many different ways can the five students be assigned?



I'll put branliest to first person

Answers

There are 20 different ways to assign five students to cover the morning and afternoon shifts at the food pantry.

How many different methods to assign 5 students?

There are different methods to solve this problem, but one possible way is to use a combination of counting techniques.

Since there are two shifts (morning and afternoon) and each shift must be covered by at least two students, there are two cases to consider:

Case 1: Two students cover the morning shift, and three students cover the afternoon shift.

Case 2: Three students cover the morning shift, and two students cover the afternoon shift.

For Case 1, we can choose two students out of five for the morning shift in C(5,2) = 10 ways, and the remaining three students will cover the afternoon shift. For each of the 10 ways of selecting the morning shift, we can choose three students out of the remaining three for the afternoon shift in C(3,3) = 1 way (since there are only three students left). Therefore, there are 10 x 1 = 10 ways to assign the students for Case 1.

For Case 2, we can choose three students out of five for the morning shift in C(5,3) = 10 ways, and the remaining two students will cover the afternoon shift. For each of the 10 ways of selecting the morning shift, we can choose two students out of the remaining two for the afternoon shift in C(2,2) = 1 way (since there are only two students left). Therefore, there are 10 x 1 = 10 ways to assign the students for Case 2.

The total number of ways to assign the students is the sum of the ways for Case 1 and Case 2, which is 10 + 10 = 20 ways.

Therefore, there are 20 different ways to assign the five students to cover the morning and afternoon shifts at the food pantry.

What is the diameter of a sphere with a volume of

,
7483 m

, to the nearest tenth of a meter?

Answers

The diameter of the sphere is approximately 20 meters to the nearest tenth of a meter.

The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere. Since we are given the volume of the sphere, we can solve for the radius as follows:

V = (4/3)π[tex]r^{3}[/tex]

[tex]r^{3}[/tex] = (3V) / (4π)

r = [tex](3V/4\pi )^{1/3}[/tex]

Substituting the given value of the volume, we get:

r = [tex](3*7483/4\pi )^{1/3}[/tex] ≈ 10.0

Therefore, the radius of the sphere is approximately 10 meters. The diameter of the sphere is twice the radius, so the diameter is approximately:

2 x 10 ≈ 20 meters
