how do I figure out which graph it is in the last part?

3. Jhannybean

That's soooo much to read e.e

4. TylerD

maybe i should goto the reading section of this site

5. TylerD

i suppose since R is being raised to a power, as R goes up, P goes down, do it doesnt seem like it could be D

how would I graph this?

9. TylerD

why are there multiple lines on the graph?

10. TylerD

oh I see it corresponds to each balance equation i did previously...?

11. TylerD

ok I might be able to solve it then, was confused because there were multiple curves...

12. TylerD

still a bit lost here, tried graphing it, get strange results.

13. TylerD

lucky guess is, got the answer as C, but havent nailed down why.

14. dan815

set r=0

15. dan815

and solve for some y intercepts

16. TylerD

if you set r=0, P=0

17. dan815

or set it to 0.00001

18. TylerD

k

19. dan815

actually when u set r=0 p is not 0 its just a 0/0 expression

20. TylerD

if i do that then i get http://www.wolframalpha.com/input/?i=y%3D%28450000*0.00000001%29%2F%28%281%2B0.00000001%29^120-1%29%29 3750, but that wasnt would correspond to graph A...

21. TylerD

wait nvm

22. TylerD

extra 0 on the 45000, k thanks man.
