Problem
ExampleProblem: 6. Suppose that the population of a certain country n years after year 2000 if there is no emigration can be modeled with the equation:

{\displaystyle P=2.5*10^{8}*e^{0.045*n}}{\displaystyle P=2.5*10^{8}*e^{0.045*n}}

Also, suppose that in the country, a net emigration of 100,000 people per month actually occurs. What is the total accumulation of people in this country from year 2000 to 2003?

b) What was the population of people in 2002, according to this model?

c) What are some possible problems with this model? For example, what doesn't it take into account? What happens when n is 100? Where did those constants come from? Would they be the same for every country, or for the same country across generations? Germanboymullae (discuss • contribs) 23:37, 27 October 2019 (UTC)
