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

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
