Question

Calculate the average rate of change in a boy's height, in inches per year, if he is 29 inches tall when he is 1 and 66 inches tall when he is 15?

Answer 1

The average rate of change in the boy's height is 2.64 inches per year.

Step-by-step explanation:

To calculate the average rate of change in the boy's height, we need to find the change in height divided by the change in time.

The change in height is 66 - 29 = 37 inches, and the change in time is 15 - 1 = 14 years. Therefore, the average rate of change in the boy's height is 37/14 = 2.64 inches per year.
