L x W = Area
40 x 15 = 600 square ft
So you would need 6 bags of feed
600/ 100 = 6
Your first point would be on (0, 2), the vertex. Then, put a point on (-2, 22). Hope that helps!
The population starts at 2000, so a=2000.
We also know that the population in 3 hours is 1000, so we can setup the equation:
2000 b^3 = 1000
This gets us:
b^3 = 1/2
And taking the cube root of both sides gives us:
b ≈ 0.7937005259841
Rounding that to 4 places, we have:
f(t) = 2000 (0.7937)^t
