Question

The population of rabbits in a forest follows the law of

exponential
growth.
If 90 rabbits are present initially and
there are 180 after 3 years, how many will here be in 4 yours

Answer 1

226.78579

Explanation

first, find k in 90(3^kx)

90(e^0) = 90 [when time is 0 years, the population is 90]

180=90(e^k3), 2=e^3k

ln2 = 3k, k=(ln2)/3

90(e^4(ln2)/3) = 90(e^ln(16)/3)

it is about 226.78579
