Situation:

A geologist in South America discovers a
bird skeleton that contains 47% of its
original amount of C-14.
N = Noekt
No = inital amount of C-14 (at time
t = 0)
N = amount of C-14 at time t
k= 0.0001
t = time, in years

Find the age of the bird skeleton to the nearest year.

Answer:

7550 years

Explanation:

From;

N = Noe^-kt

No = inital amount of C-14 (at time t = 0)

N = amount of C-14 at time t

k= 0.0001

t = time, in years

Now we have been told in the question that N =0.47 No

So we have;

0.47 No = Noe^-0.0001 t

0.47 No/No = e^-0.0001 t

0.47 = e^-0.0001 t

ln 0.47 = ln e^-0.0001 t

-0.7550 = -0.0001 t

t = 0.7550/0.0001

t = 7550 years
