Question

how to do logarithism (?) problem 90=120e^-0.01/t

Answer 1

Divide by 120
Introduce the logarithm.

Answer 2

so log 3/4 = e^-.01

Answer 3

oops that e^-.01/t

Answer 4

You almost had it.

\(3/4 = e^{-0.01/t}\)

Introduce the logarithm

\(ln(3/4) = -0.01/t\)

It's almost done.

Answer 5

I multiply then right?
the ln(3/4) by -.01

Answer 6

If I multiply I get .0028768207 which is not the right answer

Answer 7

nevermind I'm a dork I have to multiply t by both sides since it was in the denominator then dividee by ln(3/4)....duh.. Thanks for your help I need to become OCD LOL

Answer 8

Well, that was an interesting conclusion. :-)
