Ahiker in africa discovers a skull that contains 63% of its original amount of c-14.
-find the age of the skull to the nearest year-
n=n0e^-kt
n0= initial amount of c-14 (at time t=0)
n= amount of c-14 at time t
k=0.0001
t=time, in years

3820 years

Step-by-step explanation:

The age of the skull can be found using carbon-14 by applying the half-life relationship.

Age of skull is given by;

where N=63 N₀=100 -0.693=decay factor of carbon and 5730 =half-life of carbon-14, t =age

substitute values in equation
