Calc II

posted by .

Carbon-14 has a half-life of 5700 years. The charcoal from a tree killed in the volcanic eruption that formed Crater Lake in Oregon contained 59.5% of the carbon-14 found in living matter. Approximate the age of Crater Lake.

  • Calc II -

    .595=1.0 e^(.693t/5700)

    ln of each side..

    ln (.595)=.693t/5700
    solve for t in years.
