I found my c to be 3.366 but the answer is wrong

a=1 and b=8

yes, i know how to do it..but got it wrong.. don't know why

myininaya Group TitleBest ResponseYou've already chosen the best response.2
Does it want an approximation?

it didn't say..so i'm thinking should the answer be an exact number

(Enter your answers as a commaseparated list. If it does not satisfy the hypotheses, enter DNE).

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
but then i think there is only 1 number c

myininaya Group TitleBest ResponseYou've already chosen the best response.2
Well the number you put above is not the exact answer
 one year ago

myininaya Group TitleBest ResponseYou've already chosen the best response.2
That is call an appoximation
 one year ago

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
how do get an exact number?
 one year ago

myininaya Group TitleBest ResponseYou've already chosen the best response.2
So I assume you did the setup right because you got the approximation to the correct answer
 one year ago

myininaya Group TitleBest ResponseYou've already chosen the best response.2
This is the setup you chose? \[\frac{1}{c}=\frac{\ln(8)\ln(1)}{81}\]
 one year ago

myininaya Group TitleBest ResponseYou've already chosen the best response.2
We know ln(1) =? and 81=? So can you tell me what 1/c= Don't use your calculator
 one year ago

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
and then f'(c) = 1/c then solve for c
 one year ago

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
ln 1 = 0 81= 7
 one year ago

myininaya Group TitleBest ResponseYou've already chosen the best response.2
Ok we have \[\frac{1}{c}=\frac{\ln(8)0}{7}\] Do you know how to solve this for c?
 one year ago

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
ln 8/ 7 = 1/c c= 7/ln8
