In the formula A=I e^(kt),
A is the amount of material remaining from an initial amount I at a given time t and k is negative constant determined by the nature of the material.
If it has 53% of the carbon it originally contained, what is the approximate age of the artifact? (carbon decays @ a rate of 0.0125% annually.) Round to the nearest year.
What formula do I use??
The solution shows how to calculate the age of the artifact using logarithmic and exponential decay.
