Calculus: A population of chipmunks moves into a new region at time t=0 months. At time t (in months), the population numbers

P(t) = 100[1+0.3t+(0.04)t^2].

How long does it take for this population to double its initial size P(0)?
What is the rate of growth of the population when P=200?

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
