## mr.luna 3 years ago im stuck here, please solve for t.

1. MathMind

t = 1.45126

2. mr.luna

$(10/11)=(75/110)^(t/30)$

3. mr.luna

how did you get that math mind? i hadnt even posted the equation

4. myininaya

it looks like you raised one of your parenthesis does that mean t/30) should also be raised?

5. mr.luna

oops. im retyping.yes myininaya

6. karatechopper

t=440

7. mr.luna

$(10/11)=(75/110)^(t/30)$

8. mr.luna

what the heck it doesnt do it.

9. MathMind

lmfao, thanks for the medal.... you gotta type into { }

10. myininaya

$\frac{10}{11}=(\frac{75}{110})^{\frac{t}{30}}$ take natural log of both sides so then we can write $\ln(\frac{10}{11})=\frac{t}{30} \ln(\frac{75}{110})$

11. mr.luna

12. mr.luna

doesnt there have to be an e to bring down the t/30

13. karatechopper

k i just tried it i didnt really understand what myin was saying about raised so i may have it wrong

14. mr.luna

15. myininaya

remember: $\ln(x^r)=r \ln(x)$ $30 \cdot \ln(\frac{10}{11}) \cdot \frac{1}{\ln(\frac{75}{110})}=t$

16. karatechopper

i thought so.... wtheck myin???? what math level is this?!?!?!?!

17. mr.luna

ok myiniaya im working on getting your resulsts with your intial setup

18. myininaya

t is approx=7.465700356

19. mr.luna

i get 30 times( ln10/11over ln75/110)

20. mr.luna

i dont have a calculator

21. myininaya

samething

22. mr.luna

alrie thanks

23. mr.luna

do you what a medal?

24. myininaya

$30 \cdot \ln(\frac{10}{11}) \cdot \frac{1}{\ln(\frac{75}{110})}= 30 \cdot \frac{\ln(\frac{10}{11})}{\ln(\frac{75}{110})}$

25. myininaya

you can also write this a couple of other different ways

26. mr.luna

yup i got that. :)

27. mr.luna

28. myininaya

using our properties of log

29. myininaya

i prefer to be called a dudette thanks

30. karatechopper

lol myin and i r girls!

31. mr.luna

thanks sista form anotha mista. :)

32. myininaya

thats goofy but i accept lol

33. mr.luna

coo

34. karatechopper

hahahahahahahahahahaha! but i come from a mother not a father. i dont think males get pregnant....hmmmjk!
