find the average rate of change, in simplest form, of the function over the interval 4\le x \le 74≤x≤7.

Step-by-step explanation:

Given

See attachment for table

Required

Determine the average rate of change over: 4≤x≤7.

Average rate of change is calculated as:

Where:

So:

From that table:

f(4) =

f(7) =

So:

the answer to this question is 3/19

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
