A.) P(t) = 130t - 0.4t^4 + 1200
The population is maximum when P'(t) = 0
P'(t) = 130 - 1.6t^3 = 0
1.6t^3 = 130
t^3 = 81.25
t = ∛81.25 = 4.3 months.
Maximum population P(t)max = 130(4.3) - 0.4(4.3)^4 + 1200 = 1,622
b.) The rabbit population will disappear when P(t) = 0
P(t) = 130t - 0.4t^4 + 1200 = 0
t ≈ 8.7 months
The correct answer is D) Miguel: d=23t+10, Gabby d=28t
We multiply the speed of each person by t, the amount of time. This is where the 23t in Miguel's equation and the 28t in Gabby's equation come from. The starting point is added to this, which leads to 23t+10 and 28t+0 or 28t.

Answer:
80, 96, 8, 10
Step-by-step explanation:
The first set gives us the ratio, 32:2 which is basically 16
5*16= 80
6*16= 96
Notice how it is on the top now, so divide by 16
128/16= 8
160/16=10
