Explanation:
Logistic growth is a measure of continuous growth of a population of individuals in such an environment where the resources are limited. Such type of growth pattern has a characteristic growth curve which is S-shaped or sigmoidal.
The equation for logistic growth is as follows -
Change in population size = ![\frac {dN}{dt} = rN(K- \frac {N}{K})](https://tex.z-dn.net/?f=%5Cfrac%20%7BdN%7D%7Bdt%7D%20%3D%20rN%28K-%20%5Cfrac%20%7BN%7D%7BK%7D%29)
Where,
N = size of population
r = intrinsic rate of increase
K = carrying capacity
The values of r, N and K are given in the question as 12, 30 and 40 respectively.
So,
![\frac{dN}{dt} = 12 \times 30(40 - \frac{30}{40}) = 14130](https://tex.z-dn.net/?f=%5Cfrac%7BdN%7D%7Bdt%7D%20%3D%2012%20%5Ctimes%2030%2840%20-%20%5Cfrac%7B30%7D%7B40%7D%29%20%3D%2014130)
