3 0

Answer:

A, C, D

Step-by-step explanation:

In a proportional relationship, y = kx, k is the constant of proportionality.

A)

4y = x

y = 1/4 x

k = 1/4      Yes

B)

y = 4x

k = 4      No

C)

32y = 8x

y = 8/32 x

y = 1/4 x

k = 1/4    Yes

D)

y = 0.25x

k = 0.25 = 1/4     Yes

E)

1/4 y = 2x

y = 4 * 2x

y = 8x

k = 8     No

Answer: A, C, D

104 1/2ft cubed
To find the volume you would multiply
Length•width•height
So,
(6 1/3)(3)(5 1/2)=104 1/2
So it would be 104 and 1/2 or 104.5

you buy two rolls of wrapping paper. each roll has the same lateral surface area. what is the diameter of roll B?
Sonbull [250]
I saw the image that should have been posted with this word problem.

The rolls of wrapping paper is cylindrical in shape.

Roll A : length = 30 inches ; diameter = 3 inches
Roll B : length = 24 inches ; diameter = unknown

Lateral surface area = 2 π r h

Lateral Surface area of Roll A = Lateral Surface area of Roll B
2 * 3.14 * 1.5in * 30in = 2 * 3.14 * r * 24 in
282.60 in² = 150.72 in * r
282.60 in² / 150.72 in = r
1.875 in = r

diameter is 2 times the radius = 1.875 in * 2 = 3.75 inches

The diameter of Roll B is 3.75 inches.

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the curves about the given
Fed [463]
See attachment for one such shell. The volume is given by the sum of infinitely many thin shells like this, each with radius x and height determined by the vertical distance between the upper blue curve and the lower orange curve for any given x, i.e. 8e^x-8e^{-x}.

The volume is then

2\pi\displaystyle\int_0^1x\left(8e^x-8e^{-x}\right)\,\mathrm dx=16\pi\int xe^x(e^{2x}-1)\,\mathrm dx=\dfrac{32\pi}9(e^3-4)\approx179.677

Answer:

  • A. f(n) = (n + 1)^2 – 1

Step-by-step explanation:

Figure 1

  • 3 = 4 - 1 = 2² - 1 = (1 + 1)² - 1

Figure 2

  • 8 = 9 - 1 = 3² - 1 = (2 + 1)² - 1

Figure 3

  • 15 = 16 - 1 = 4² - 1 = (3 + 1)² - 1

<u>The function is:</u>

  • f(n) = (n + 1)² - 1
