where t=0 is the year 2000.When will the population double from its size at t=0?first correct answer gets best answer.-P(0) = 2.4.4 = 2.......
The population of a city (in millions) at time t (in years) is P(t)= 2.2 e^{0.008 t}, where t=0 is the year 2000.

When will the population double from its size at t=0?

first correct answer gets best answer.

-
P(0) = 2.2

4.4 = 2.2 e^0.008t
2 = e^0.008t
ln 2 = 0.008t
86.64339757... = t

The population will double in the year 2086.

-
Year 87 or 2087.

Crappy pop. model, we have much faster growth!
