Best ResponseYou've already chosen the best response.0That's what I got as well. I have another question if you're up for it: A gorilla habitat can support no more than 250 gorillas. 28 gorillas were initially in the habitat. Assume the rate of growth is \[dP/dt=.0004P(250P)\] where t is in years. Derive a formula for the gorilla population in terms of t using partial fractions.
