Question 276809: *URGENT*
use the exponential growth function, P(t)=Poe^kt, to find the value of k, then write the write the function for this population as a function of time, t.
Use the function to presict the population in 2005 if it continues to decline at the same rate.
1984= 746,388,000 1974=574,220,000 t=0 1974 t=10 1984
The answer has to be 15,531

First of all, this population is increasing, not declining. So the population will never get down to 15,531.

Recently someone posted pretty much the same problem. It had the same years and populations and the problem was to find k. I found k and the resulting equation. Click here to see it.

Then, to find the population in 2005, take the equation and substitute 31 for t (since 2005 - 1974 = 31 and 1974 is the "zero" year for the equation). Then use your calculator to find the population in 2005.
