Question 443135: Please help me with this problem I am having a diffcult time with it, Than you so much.
The population P in 1999 for a state given along with r, its annual percentage rate of continuous growth
P= 21 millions, r= 1.9%
(a) Write the formula f(x) = P e^yx, where r is in the decimal notation, that models the population in millions x years after 1999.
(b) Estimate the population in 2020
F(x) = ?
The population in 2020 will be approximately how many million?
(round to the nearest tenth as needed)
Any help is greatly appreciated!!!

You can put this solution on YOUR website! The population P in 1999 for a state given along with r, its annual percentage rate of continuous growth
P = 21 millions, r= 1.9%
(a) Write the formula f(x) = P e^rx, where r is in the decimal notation, that models the population in millions x years after 1999.
f(x) = 21*e^.019x
:
(b) Estimate the population in 2020, (that's 21 yrs after 1999)
F(x) = 21*e^(.019*21)
f(x) = 21*e^.399
Find e^.399 on a calc
f(x) = 21 *1.4903
f(x) = 31.3 million in 2020
