A 4-foot tree was planted in 1984. The tree grows continuously by 22% each year from this point forward. Find the height of the tree after 8 years.

Given:

Initial height of a tree in 1984 = 4 foot

Continuous growth rate =22%

To find:

The height of the tree after 8 years.

Solution:

The general continuous growth model is

Where, is the initial value, r is the growth rate and t is the time in years.

Putting in the above formula, we get

Therefore, the height of the tree after 8 years is 23.25 foot.
