Answer:
Explanation:
The half-life of carbon (5730 y) is the time it takes for half the carbon to decay.
After one half-life, half (50 %) of the original amount will remain.
After a second half-life, half of that amount (25 %) will remain, and so on.
We can construct a table.
<u>No of half-lives</u> <u>Fraction remaining</u>
1
2
3
The general formula is

where <em>n</em> = the number of half-lives.
Thus,
of the original carbon remains after 17 190 y.
