Radioactive decay. lodine-131 has a decay rate of 9.6% per day. The rate of change of an amount N of iodine 131 is given by dN = -0.096 N dt where t is the number of days since the decay began. a) Let No represent the amount of iodine-131 present at t = 0. Find the exponential function that models the situation. N(t) = Noe t b) Suppose that 500 g of iodine-131 is present at t = 0. How much will remain after 4 days? Number after 4 Days (Round to the next whole number) c) After how many days will half of the 500 g of iodine-131 remain? yr (Round to 1 Decimal) T=
