@East: You're welcome! Glad it did Sorry, I just noticed two mistakes. Dividing is the same as multiplying [b]by[/b] the reciprocal* & when logging both sides, there should be a negative in front of Rt/L

@Emoticon: I couldn not solve the problem, not because it was hard, but because I was not yet educated with the fundamentals to do so. I could not care less about the correct answer. I was ultimately looking for an explanation of the process in solving the problem.

Thank you so much! It really helped. I really appreciate it.
Glad the basil community is always so helpful

@djhfreak: Lol? I didn't ask for your opinion. And why does it even concern you?
Plus, I was kinda rushing it since I wanted to post it for her to see. [i]Sure[/i], I'll re-post it. But it's not for you; it's for her.
I love how you criticized me based on one picture when you don't even know what my best handwriting looks like.

[quote=djhfreak]why is your handwriting terrible omg[/quote]

It actually looks like letters, unlike your chicken scratch.

Sorry, you have to flip the image. I don't know why it won't let me upload it when I flip it
If you have any questions, ask
By the way, when I put, "log both sides," under it is an arrow LOL. It looks like a 'b.'[/quote]

why is your handwriting terrible omg

@michaelsho: yes lol. also multivariable calculus

Does your school have an AP Calc AB and an AP Calc BC course?

[quote=East]@michaelsho: how did you get B?

EDIT: Nvm. Thank you so much [/quote]

No problem. If you need anymore help you can always PM me or post another thread XD

Is the answer B? Its pretty easy once you know how to do it. I just tried to do it in my head though so maybe i messed up. First you would divide E/R to the opposite side which gives you RI/E. Next subtract the 1 over which gives RI/E-1 and you can also bring that negative over to make it 1-RI/E=e^-Rt/L. Then you would take the log of both sides which gives log(1-RI/E)=-Rt/L. taking the log of e just makes it disappear. Now solve for t and yea.

are u sure this isnt an ACT math question?

@michaelsho: how did you get B?

EDIT: Nvm. Thank you so much

I believe the answer is B

First You isolate e^(-Rt/L)

So it becomes 1-(RI/E)=e^(-Rt/L)

Then you natural log each side to get:
ln(1-(RI/E)) = (-Rt/L)
Then Multiple both sides by (-L/R) to get t by itself.

Which would be B I think
I'm not that good at math so someone correct me please XD
