the population P(t) of a new residential development t years after 2010 is P(t)=8000(1-e^-0.3). What is the population for 2015?
replace t with 5 and evaluate using your calculator
(I got 6215)
I was the population to increase in a new development.
Are you sure your formula is correct?
6215 is the right answer. What were the steps without a calculator? Thanks!
To evaluate e^(-.15) without a calculator would be beyond the scope of most of today's college students.

-x+4y=12 m= b=
