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:
Answer:
impossible
Step-by-step explanation:
a denominator can’t be equal to 0. So:
d ≠ 0 ; d ≠ 2
(10 + 4d - 8)/d(d-2) = 5d/ d(d-2)
4d + 2 = 5d
d = 2
But we have said that d can’t be equal to 2, so the equation is impossible.
Hello there! The lines between the a are absolute value symbols, and absolute value symbols are always positive. They are the distance a number is away from 0. We are looking at the values less than 3, so this is definitely not an or statement. C and D are eliminated. The compound inequality would be -3 ≤ x ≤ 3. A is the answer choice that fits this. The answer is A.
