Situation:
A hiker in Africa discovers a skull that contains 41% of its original amount of C-14.
N=Noe^-kt
No=initial amount of C-14(at time t=0)
N=amount of C-14 at time t
t=time, in years
k=0.0001

Find the age of the skull to the nearest year.

anonymous · Answer

you know that N=0.41No so if you sub that in the No's cancel and you get 0.41=e^-kt.
solving for t you get t=(ln0.41)/(-k)=8915.98=8916 (to the nearest year)
