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

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
