The burial cloth of an Egyptian mummy is estimated to contain 56% of the carbon-14 it contained originally. How long ago was the mummy buried? (the half-life of carbon-14 is 5730). Please round the answer to the nearest tenth. I have figured that:
m(t) = Moe(-ln2/5730) is a starting point
Pre Calculus -
P14 = fraction of C14 found in sample (0.56)
T1/2 = radioactive half life (5730 years)
Age of sample
=T1/2*(ln(P14)/ln(0.5)) (Before present)
