It is known that the mass, m(t), of a radio-active substance decreases as it decays, and that the equation governing this is m′(t)=−0.015m(t) where t is in years. What is the half-life? (Hint: Find an exponential function which solves the equation. You will then have a formula for the mass, so you can find the half-life.)
