If a clock loses 5 minutes every day that means it loses 5 minutes every 24 hours. the question askes us how much it will lose in 2 hours. hours have a ratio of 12:1 so will minutes will have 5 /12 = 0.416.
it will loose 0.416 min so it will lose 25 seconds
the answer is
(C) The intervals on one axis do not need to be of equal size.
The total amount that Shelley earned is $423.88.
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
