In september 1998 the population of the country of West Goma in millions was modeled by f(x) = 16.7e^0.0006x. At the same time the population of East Goma in millions was modeled by g(x) = 13.7e^0.0187x. In both formulas x is the year, where x=0 corresponds to September 1998. Assuming these trends continue, estimate the year when the population of West Goma will equal the population of East Goma.

Best ResponseYou've already chosen the best response.0you have said to estimate x when both populations are equal... so, it is assumed that both populations are equal and written as 16.7e^0.0006x=13.7e^0.0187x The entire equation is divided by 13.7e^0.0187x which gives, 16.7e^0.0006x/13.7e^0.0187x=1 splitting the terms (16.7/13.7)(e^0.0006x/e^0.0187x)=1 16.7/13.7=1.21 e^0.0006x/e^0.0187x=e^0.0181x so we get, 1.21e^0.0181x=1 divide the whole equation by 1.21, e^0.0181x=0.8264 taking natural logarithm on both sides, 0.0181x= 0.190676361 => x=10.53 x cannot be decimal number so approximating it to the closest integer 11 so aftr 11 yrs from 1998 population will be equal that is at 2009 population will be equal
