A radioactive substance decays at a rate proportional to the amount (mass) that is present. Denote the proportionality constant by the letter r. Suppose we start with 1 kg of the substance. (a) (1pt) Write the differential equation and initial condition for the mass m(t) of the substance as a function of time t (measured in hours). (b) (1pt) Find the solution as a function of t and r. (c) (1pt) Suppose that, one hour later, 0.8 kgs remain. Find The constant r. (d) (1pt) Suppose we measure time in minutes. Find the differential equation for m(s), if s denotes time in minutes.
