1. The problem statement, all variables and given/known data
uh for my lab report the problem is i have to solve for the constnat and the lnC??? look below


2. Relevant equations
teacher said something about LnT =Lne^-kt +LnC
transposes into ==> LnT = -kt +LnC
uh and i have the temperatures to do this.. but i dont know exactly what im trying to do

3. The attempt at a solution
seen as i dont know how to do it and im only in precalc i dont really get what im trying to do... as well can someone explain what this formula means?????

Welcome to PF.

Here is a link that discusses the properties of natural logarithms:

Perhaps that will help you understand the transform.
