Question

A group of marine biologists estimates that if certain conservation measures are implemented, the population of an endangered species of whale will be: N(t) = 3t^3 + 2t^2 - 10t + 600 0 le t le 10 where N(t) denotes the population at the end of year t. Find the average population of the whales over the next 10 years. The concentration of a drug (mg/cm^3) in a patient's bloodstream t hours after injection is: c(t) = 0.2t/t^2 - 1 Determine the average concentration of the drug in the patient's bloodstream over the first 4 hours after the drug is injected.

Explanation / Answer

N (10) =3000+200-100+600=3700

Average = 3700/10 = 370 per year
