Carbon 14 decays at a constant rate, so it can be used to determine the age of fossils. In particular, if the original amount
of Carbon-14 presentis Athen A - A can be used find the amount of amount of Carbon 14 remaining after
years. Given that the half-life of Carbon-14 is 5.730 years, what is the value of the decay constant kto 5 decimal places?
