Equation for the work:
The equation for the work done is given by:
In which F is the force needed and d is the distance. The time does not interfere on the work.
A 300-lb gorilla climbs a tree to a height of 30 ft
This means that
Thus
The work done in both cases is of 9000 ft-lb, as the work is not a function of time.

Answer:
The rate of change is -1.5.
Step-by-step explanation:
Given : Function
To find : The average rate of change of the function over the interval -2<x<8?
Solution :
The average rate of function f(x) between the interval a and b is given by,
Here, and a=-2 and b=8
Substitute,
Therefore, the rate of change is -1.5.
