Question

6. Carbon-14 is used to determine the age of artifacts in carbon dating. Carbon-14 has a half-life of 5730 years.
a) Write an exponential decay function for a 52-mg sample.


b) Find the amount of carbon-14 remaining after 10,000 years (round answer to the nearest tenth).

Answer 1

start of by writing down the general decay equation'

\[M=M _{0}e ^{-kt}\]

Answer 2

\[ M _{0} = original mass\]

Answer 3

Now we have to find the constant k

Answer 4

any ideas?
