We have an exponential function for the population A(t) and we have to find the growth rate.
This can be expressed as:
For the exponential formula we get:
The growth rate is 0.003 or 0.3%.
We can calculate the time needed to double the population dividing ln(2) by the growth rate:
Answer:
a) The growth rate is 0.003 or 0.3%
b) The number of years to duplicate the population is 231 years.
