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
Answer:
<em>(C). b + (2 × 35) = 180; b = 110°</em>
Step-by-step explanation:
Answer: 132.72 ft squared
Step-by-step explanation:
A=132.72
Base:7.5
Base: 24.1
Height: 8.4
Solution
A=a+b
2h=7.5+24.1
2·8.4=132.72
