(a) Express the population after t hours as a function of t.

this is what i put as my answer but i guess its not right do i replace the four with t??

260e^tln4/4

- math -
**drwls**, Sunday, November 8, 2009 at 8:11pmThe population apparently doubles in 2 hours.

P = 260 * 2^(t/2) is a simpler way to write it.

Note that e^(t ln4/4)= [e^(ln4)]^(t/4)

= 4^(t/4)= [2^2]^(t/4) = 2^(t/2)

Your version is apparently correct, but needs to be simplified
