In 1990 the populations of a country was estimated at 4 million. For any year the population is modeled by this logistic equations: P(t)= (240)/(5+54.99e -.0208t) , where is the number of years since 1990. Estimate the year that the population will be 21 million.
Population of country in 1990 = 4 million
Population for any year logistic equation
The year when population will be 21 million
Put p(t) = 21 in giv...
