Question

Need help with this function please.

Answer 1

well the initial population, t = 0 is 215...

so you need to find when will the population be 430

so

\[430 = 215e^{0.0106t}\]

or

\[2 = e^{0.01.6t}\]

solve for t using logs...

so when you ahve the value of t, you may need to add it to 1980 to find the year the population will be double.

hope this helps

Answer 2

oops typo, should read

\[2 = e^{0.0106t}\]
