Answer:

36. m = (3/2)n

37. s = 5tv

38. c = 3/d

Step-by-step explanation:

Each of the variations in these problems has its own associated equation. You only need to make use of the given values to find the constant of variation (k) and fill in the equation.

direct variation: y = kx; k = y/x
joint variation: z = kxy; k = z/(xy)
inverse variation: y = k/x; k = xy

_____

36. The constant for direct variation is the ratio of the given values:

k = m/n = 18/12 = 3/2

Then the equation for the direct variation is ...

m = (3/2)n

___

37. The constant for the joint variation is the expression ...

k = s/(tv) = 8/((4/5)·2) = 8/(8/5) = 8·5/8 = 5

Then the equation for the joint variation is ...

s = 5tv

___

38. The constant for the inverse variation is the product of the given values:

k = cd = (1/4)(12) = 3

Then the equation for the inverse variation is ...

c = 3/d

Find the next three terms of the sequence?

forsale [732]

Answer:

The correct answer is D. -2,592, -15,552, -93,312

Step-by-step explanation:

Each of the terms is the previous term multiplied by 6. You can find this by taking any term and dividing it by the one before it. The answer will always be 6.

-72/-12 = 6

-12/-2 = 6

So, in order to find the next 3, we take the last term and multiply it by 6.

-432 * 6 = -2,592

-2,592 * 6 = -15,552

-15,552 * 6 = -93,312

<em>We will assume the tent is in the shape of a triangular prism.</em>

The volume of a triangular prism can be found with the following formula, where $b$ is the width at the base, $h$ is the height, and $l$ is the length.
