Question

An old bone contains 80% of its original carbon-14. Use the half-life model to find the age of the bone. Find an equation equivalent toP (t) = A (one-half) Superscript StartFraction t Over 5,730 EndFraction

Answer 1

P(t) over A is equivalent to (one-half) Superscript t Over 5,730

Answer 2

First Part: D    P(t)/A=(1/2)^t/5,730

Second Part: 0.8

Third Part: B    about 1,845 years
