Answer:

B

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here a = 1 and b = 3

f(b) = f(3) = 27 ← value of y corresponding to x = 3

f(a) = f(1) = 3 ← value of y corresponding to x = 1, thus

average rate of change = \frac{27-3}{3-1} = \frac{24}{2} = 12 → B

Missing side length
Gwar [14]

Answer:

m = 5

Step-by-step explanation:

We are told that the two triangles are similar.  Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.

Thus, 12 = k(7.2), where k is the constant of proportionality.

Solving this for k, we get

k = 12/7.2 = 1  2/3

Thus, side m is 1  2/3 times 3, or  5/3 times 3, or just 5.

m = 5
