Answer:

3/π Hz

Step-by-step explanation:

Recall that for a cos function in the form

y = A cos Bx

period = 2π / B

frequency = 1/period = B/2π

Given y = -5 cos 6x

A = -5 and B = 6

frequency,

= B / 2π

= 6 / 2π

= 3/π

Find the average rate of change from x = 3 to x = 15 for the function f(x) = 0.01(2)x and select the correct answer below.
Nesterboy [21]

x=3:

0.01*2^3 = 0.08

x=15:

0.01*2^15 = 327.68

327.68 - 0.08 = 327.60

15-3 = 12


327.6/12 = 27.3
