7.6: Population Growth and the Logistic Equation

WebExample: Population Growth Consider the population of bacteria described earlier. This population grows according to the function f (t) = 200e0.02t, f ( t) = 200 e 0.02 t, where t t is measured in minutes. How many bacteria are present in the population after 5 hours (300 ( 300 minutes)? When does the population reach 100,000 bacteria? WebLet us say your differential equation is dN/dt = f (t)/h (N (t)). Thus h (N (t)) dN/dt = f (t). Integrating with respect to t gives \int h (N (t)) dN/dt dt = \int f (t) dt The left integral can be integrated by using substitution u = h (N (t)), du = h' (N (t)) dN/dt dt. \int h (u) du = \int f (t) dt Then you can integrate. 1 comment ( 7 votes) WebMalthusian Growth Model. The simplest model was proposed still in 1798 by British scientist Thomas Robert Malthus. This model reflects exponential growth of population and can be described by the differential equation. where is the growth rate (Malthusian Parameter).
