Suppose the population of a country in 1985 was 145 million. In 1995 it was 190 million. Use the formula P = Ae kt to setup an expression to estimate the population of the country in 2005.
Hello,
14510^6=Ae^(k1985) (1)
19010^6=Ae^(k1995) (2)
(2)/(1)==>190/145=e^(k10)
==>10k=ln(38/29)==>k=1/10ln(38/29)
==>k=0,0270290....
14510^6=Ae^(0.02702901985)
A=7,249810...e-16
P=7,249810...e-16 e^(0,02702902005)=248 965 517,24...
≈248.965517 *10^6
