A chemical substance has a decay rate of 8.3% per day. The rate of change of an amount N of the chemical after t days is given by = - 0.083N. dt a) Let Ng represent the amount of the substance present at t= 0. Find the exponential function that models the decay. b) Suppose that 300 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 300 g of the substance remain? a) N(t) = b) After 5 days, g will remain. (Round to the nearest whole number as needed.) c) After 5 days, the rate of change is g/day. (Round to one decimal place as needed.) d) Half of the substance will remain after days. (Round to one decimal place as needed.)
