WebThe bigger the population, the more new rabbits we get! When the population is 2000 we get 2000×0.01 = 20 new rabbits per week, etc. So it is better to say the rate of change (at any instant) is the growth rate times the population at that instant: dNdt = rN. And that is a Differential Equation, because it has a function N(t) and its derivative. Web- [Narrator] The population P of T of bacteria in a petry dish satisfies the logistic differential equation. The rate of change of population with respect to time is equal to two times the population times the difference between six and the population divided by 8000, where T is measured in hours and the initial population is 700 bacteria.
