SOLVED: Radioactive substance decays exponentially: The mass at time t is m(t) = m(o)e^(-kt), where m(o) is the initial mass and k is a negative constant. The mean life of an atom of the substance is given by the integral of e^(-kt) dt. For a radioactive isotope, the value of k is 0.177. Find the mean life of the isotope. (Round your answer to one decimal place.)

SOLVED:A sample of radioactive material decays over time (measured in hours) with decay constant .2. The graph of the exponential function y=P(t) in Fig. 7 gives the number of grams remaining after t hours. [Hint: In parts (c) and (d) use the differential equation satisfied by P(t) . (a) How much was remaining after 1 hour? (b) Approximate the half-life of the material. (c) How fast was the sample decaying after 6 hours? (d) When was the sample decaying at the rate of .4 gram per hour?
