PLZ HELP ME
I appreciate any help, especially if you can show me how you got the answer

Some calculus, a little better than the usual slopes and distances.

L'Hopital applies because the numerator is sin 0 = 0 and the denominator is ln(2 e^0 - 1) = ln 1 = 0 so we have 0/0, case number one for L'Hopital.

Evaluating the latter form at t=0 we get

C  1/2

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
