The formula for it is easy to use,but difficult to compute in this website,so I won't be writing it out.
Answer:
2055 km²
Step-by-step explanation:
The amount of forest remaining after t years can be modeled by the exponential equation ...
remaining = original · (multiplier each year)^(number of years)
area = 4100·0.955^t
Then for t=15, the area is ...
area = 4100·0.955^15 ≈ 2055.1 . . . . km²
The area of the forest after 15 years will be about 2055 square kilometers.
there are four terms in this expression with each factor
Answer:
38 dollars and 25 cents
