2) Carbon dating: You may use the equation A(t) = A_0 e^{kt} for the amount of carbon-14 at year t. First find the value of the decay constant k from the half-life of carbon-14, 5730 years. In other words from 1/2 A_0 = A_0 e^{k cdot 5730} find k. Then find the age of a piece of wood containing 5% of its original carbon-14.

The decay of Carbon-14 follows the differential equation N'(t) = -kN(t), where N(t) is the amount present at time t, and t is measured in years. Using the approximate value of k = 0.0001216, calculate how old a specimen is if it has one-third of its original Carbon-14. You may either give a formula using e or ln, or a number accurate to the nearest year.

The half-life of carbon-14 is 5730 years. An object has been found that had an initial amount of 25 carbon-14. Currently, there remains 15 of the carbon-14 in this item. Write an exponential decay equation to represent the amount of carbon-14 that remains after years. Then use this function and solve an appropriate equation to determine the age of this item.

The radioactive isotope carbon- 14 is used for radiocarbon dating. The half-life of carbon- 14 is $5.73 \times 10^{3}$ years. A wooden artifact in a museum has a $^{14} \mathrm{C}$ to $^{12} \mathrm{C}$ ratio that is 0.775 times that found in living organisms. Estimate the age of the artifact.
