Concept explainers
The Pacific halibut fishery has been modeled by the differential equation
where y(t) is the biomass (the total mass of the members of the population) in kilograms at time t (measured in years), the carrying capacity is estimated to be M = 8 × 107 kg, and k = 0.71 per year.
(a) If y(0) = 2 × 107 kg, find the biomass a year later.
(b) How long will it take for the biomass to reach 4 × 107 kg?
