Acertain forest covers an area of 4500 km^2. suppose that each year this area decreases by 8.75%. what will the area be after 5 years?

The area of forest after 5 years is 2846.93 square kilometer

Solution:

Given that, A certain forest covers an area of 4500 square kilometer

Suppose that each year this area decreases by 8.75%

To find: Area after 5 years

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 = 4500

t = 5 years

Substituting the values in formula,

Thus the area of forest after 5 years is 2846.93 square kilometer

17 1/3

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
