Answer:
![[km^2]](https://tex.z-dn.net/?f=%5Bkm%5E2%5D)
Step-by-step explanation:
In this problem, the initial area of the forest at time t = 0 is

After every year, the area of the forest decreases by 9.8%: this means that the area of the forest every year is (100%-9.8%=90.2%) of the area of the previous year.
So for instance, after 1 year, the area is

After 2 years,

And so on. So, after t years, the area of the forest will be

And by substituting the value of A0, we can find an explicit expression:
![[km^2]](https://tex.z-dn.net/?f=%5Bkm%5E2%5D)
Answer by JKismyhusbandbae:


You would divide both 12 and 7n by 7. To isolate the variable. You end up with 5+n. You can not say 5n because you cannot combine unlike terms. Your answer would be 5+n. Hope this helps
P(2) is 14, because the <em>2</em> represents where the number in<em> t,</em> so you have to find the number under 2, so you get 14.
P(2)=14
It means the temperature will be three degrees below 0.
