dN A chemical substance has a decay rate of 8.9% per day. The rate of change of an amount N of the chemical after t days is given by dt a) Let No represent the amount of the substance present at t= 0. Find the exponential function that models the decay. b) Suppose that 400 g of the substance is present at t=0. How much will remain after 5 days? c) What is the rate of change of the amount of the substance after 5 days? d) After how many days will half of the original 400 g of the substance remain? a) N(t)= = -0.089N.
