The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there are 1200 after 1 day, what is the size of the colony after 3 days?
When will there be 10,000?
Am I plugging it in wrong or what?
This is the formula and I just can't get either answer and it's pissing me off!

I got 1728 for 3 days and 13 days to go over 10000.
This was just guesstimating but yeah you will have k=ln(1.2).

N(0) is 1000
we know at t = 1, N(1) = 1200 = 1000*e^k(1)
therefore, e^k = 1200/1000 = 1.2
k = ln(1.2)
so, at N(3) = 1000*e^(ln(1.2)*3) 4/7/2008 10:53:05 PM |

If its webassign with its usual fucktardedness then theoretically you'll still be on the "12th" day when you reach the 10000 threshold. 4/7/2008 11:02:18 PM |
