Radioactive decay.Carbon-14 has a decay rate of 0.012097% per year. The rate of change of an amount N of carbon-14 is given by -0.00012097N dN dt where t is the number of days since the decay began. a) Let No represent the amount of carbon-14 present at t = 0. Find the exponential function that models the situation. N(t) = Noe b) Suppose 200 g of carbon-14 is present at t = 0. How much will remain after 800 yr? (Round to the next whole number) Number after 800 yr = c) After how many years will half of the 200 g of carbon 14 remain? yr (Round to 1 Decimal) T =
