A model that describes the population of a fishery in which harvesting takes dP place at a constant rate given by = kP - h, where k and h are posi- dt tive constants,
The population of a community is known to increase at a rate proportional to the number of people present at time t. If an initial population P, has doubled in 5 years, how long will it take to triple? The population of a town grows at a rate proportional to the population present at time t. The initial population of 100 increases by 10% in 13 years. what will be the population in 27 years ?
