The time at which the population reach 5000 is 13.4 years.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The time taken to reach a population of 5000 is,
[tex]P(t) = 1000e^{0.12t}\\5000= 1000e^{0.12t}\\5 = 1000e^{0.12t][/tex]
Take a log on both sides.
ln( 5 ) = 0.12t
t = ln ( 5 ) / 0.12
t = 13.4 years.
Therefore the time at which the population reach 5000 is 13.4 years.
