Question

Find the average rate of change of the tree over time. In 1965 the tree has a diameter of 135 in. And in 2005 it has a diameter of 139 in. B)Predict the diameter in 2035.

Answer 1

0.1 in per year ; 142 in

Explanation:

Giveb that :

Diameter of tree in 1965 = 135 inches

Diameter of tree in 2005 = 139 inches

Average rate of change:

Change in diameter / change in time

(139 - 135) / (2005 - 1965)

4 / 40

= 0.1 in per year

Predict diameter in 2035;

Initial diameter + (average rate of change * (Number of years from initial)).

135 in + (0. 1 * (2035 - 1965))

135 in + (0.1 * 70)

135 in + 7 in

= 142 in
