Answer:

Growth

Step-by-step explanation:

Given

\frac{2}{3}(2.5)^x

Required

Growth or decay

The general form is:

y = ab^x

Such that:

b = rate

For b, we have the following conditions:

b > 1 ----- Growth

0 --- Decay

b = 1 ---- None

Compare \frac{2}{3}(2.5)^x to y = ab^x

b = 2.5

<em>Because 2.5 > 1, then the first condition applies (growth)</em>

s344n2d4d5 [400]

Answer:

D.

The length of the granite must be less than 120 inches.

Step-by-step explanation:

Let x inches be the widht of the section. If the length is 3 times the width, then the length is 3x inches.

The perimeter of the rectangle is

P=2(\text{width + length})

Hence,

P=2(x+3x)=2\cdot 4x=8x

The perimeter of the section must be less than 320 inches, so

8x
