The amount of a certain radioactive substance at time t is given by A(t) = 9e^(kt) for some constant k. Determine, as a function of k, the half-life of the substance.
Added by Belen M.
Step 1
We know that the half-life is the time it takes for the substance to reduce to half of its initial amount. So, we want to find the time t when A(t) = A(0)/2, where A(0) is the initial amount of the substance. Show more…
