The points (1, 5), (5, 10), (7, 8) and (8, 1) are on the graph of the function p. which expression below gives the average rate of change of the function p on 5 ≤ x ≤ 8?

1. 8-5/7-1

2. 8-5/1-10

3. 7-1/8-5

4.1-10/8-5

3.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
