Fan and Medal! Help please!
Carbon14 decays at a constant rate, so it can be used to determine the age of fossils. In particular, if the original amount of Carbon14 present is A0, then A(t) = A0e^(kt) can be used find the amount of amount of Carbon14 remaining after t years. Given that the halflife of Carbon14 is 5,730 years, what is the value of the decay constant k to 5 decimal places?
