a certain forest covers an area of 2300 km^2. suppose that each year this area decreases by 4%. what will the area be after 12 years?
round your answer to the nearest square kilometer.

The value of area after 12 years is 1409 square kilometer

Solution:

Given that,

A certain forest covers an area of 2300 square kilometer

Suppose that each year this area decreases by 4%

To find: Area after 12 years

This is decreasing function

The decrease function is given as:

Where,

y is the value after t years

A = initial amount

r = decreasing rate in decimal

t is the number of years

Here in this sum,

A = 2300

t = 12 years

Substituting the values in formula,

Thus value of area after 12 years is 1409 square kilometer
