Solving Newtons Cooling Law: LnT = -kt +LnC

[xlgurulx]

Newtons cooling law?

Homework Statement

uh for my lab report the problem is i have to solve for the constnat and the lnC? look below

Homework 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 don't know exactly what I am trying to do

The Attempt at a Solution

seen as i don't know how to do it and I am only in precalc i don't really get what I am 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.
