If carbon-14 has a half-life of 5750 years, to the nearest 1000 years, how old is the skeleton? ----------- A(t) = A(o)(1/2)^(t/5750) 0.01A(o) = A(o)(1/2)^(t/5750) 0.01 = 0.5^(t/5750) Take the log of both sides to get: log 0.01 = (t/5750)*log0.5 t/5750 = log0.01/log0.5 =6.64385619... t = 38202 yrs ============== Cheers, Stan H.
