SOLVED:A radioactive substance decays according to the formula Q(t)=Q0 e^-k t where Q(t) denotes the amount of the substance present at time t (measured in years), Q0 denotes the amount of the substance present initially, and k (a positive constant) is the decay constant. a. Show that half-life of the substance is t̅=(ln2) / k b. Suppose a radioactive substance decays according to the formula Q(t)=20 e^-0.0001238 t How long will it take for the substance to decay to half the original amount?
