Answer:
7550 years
Step-by-step 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
