\[Population=(initial amount)e ^{kt}\] (2,225) 2 corresponds to years Let t=years 225 correspond to population Let population=225

i think i have the 100 and 225 backwards
anonymous
  • anonymous
Yes you did. I said let 225=population 100 is initial amount. If you think about it, it doesnt make sense.

okay so the equation is \[225=100e ^{2k}\]

pop = initial pop e ^rate * time?
phi

notice that you also know the point (0,100) you start with 100 = A e^(k*0) 100= A e^0 100= A that is how you know A is 100
