A population gorws according to the equation P(t)= 60005500e^0.159t for t> or equal to 0, t measured in years. This population will approach a limiting value as time goes on. During which year will the population reach half of this limiting value?
(A) Second
(B) Third
(C) Fourth
(D) Eighth
(E) Twentyninth
What is a limiting value?

Take the limit as t goes to infinity. The exponential term goes to 0, leaving you with 6000.
And if you need additional info from what special K said, just take half of 6000 and solve the equation for it. You can either use logs or just plug & chug since you have multiple choice.
Wait, I don't think this is really a calculus problem. Looks more like plain algebra to me.

ive taken up to calc 3. yea it was fun. and yea we talked about stuff like that in calc. so id consider it a calc question.
bench: 240
squat: 260
deadlift: 300
height:6'
weight:183 (12%bf)
what did you get then?

From now on, just go here: http://www.sosmath.com/CBB/index.php
God damn it. The limit is 6000 so plug in 3000 for P(t) and solve for T and you get...
t = 3.81
SO during 3.81 years you are on the FOURTH year. So 'C' should be correct and that makes yankeekd25 and Cirino83 are incorrect (Ha, just had to screw with you guys).
And yes I used my graphing calculator because why else would I ****ing buy it and not use it?
Damn your calc problem thread has been bugging me all day. DONE! FIN! Somebody lock this thread.
Sadly enough the first two replies explained how to solve it quite well.

thank u guys. i didnt mean to bug ya... just needed a little help.

It seems like every math problem thread gets 10+ more replies than are necessary.
I am SO glad I'm female.
Seriously  I had NO IDEA it was this complicated.
I just tell my husband he makes love like a God, feed him a steak, and I'm done for the day. Super easy.
God bless men.  Built
he probably didnt mean it to be. That is calculus because the formula to find the exponential growth/decay can be derived from something or other. I just covered it in class a few weeks ago, but i was asleep so i don't remember fully why it has to do w/ calc.
Been out the game for a little while, but jumpin back in
While I may have been right about finding the answer, it looks like Ron and I are *technically* wrong in that limits are considered part of calculus (if we're going by Wiki's definition).Originally Posted by Wiki

you don't actually have to take a limit to get the answer lol

But then how would you know when you're at half of the maximum? Even if you don't write it on paper you have to look at it and calculate where the function would go when 't' goes toward infinity. That by definition I would think is considered taking the limit since you can't mathematically plug in infinity for 't'.
Anyway you guys are making me feel like a mentally masturbating nerd right now.

Or maybe you could have set it up as the ratios of the two being equal to 1/2 and then try to solve for 't' or something I guess. If you could do that then it wouldn't be calculus.
