A geologist in South America discovers a bird skeleton that contains 77% of its original amount of C-14.

Find the age of the bird skeleton to the nearest year

N=N0e^-kt

N0 just means the amount of C-14 at time zero (when the bird dies), or the initial number of grams

Step-by-step explanation:

.57*N0 = N0*e^(-0.0001*t)

N0 cancels out

.57 =e^(-0.0001*t)

ln(.57) = -.0001*t

ln(.57) / -.0001=t

t = 5621.189

the bird's skeleton is 5621 years old
