The number of acres in a landfill is given by the function a = 2100e -0.05t , where is measured in years. use the following graph to approximate, to the nearest hundred, how many acres will the landfill have after 20 years and 40 years?

Given that:

The number of acres in a landfill is given by the function

where, t is measured in years.

We have to find how many acres will the landfill have after 20 years and 40 years.

For t = 20 years.

Simplify:

Similarly, for t = 40 years

Simplify:

Therefore, the acres will the landfill have after 20 years and 40 years to the nearest hundredth are, 772.55 and 284.21

c > -10.55

step-by-step explanation:
