A cleaning process reduces the amount of chlorine in contaminated water by 5% per hour. Using Co for the initial amount of chlorine, find an exponential function C' (r) that gives the amount of chlorine remaining after / hours. (Provide an answer in the form a (B) . Express numbers in exact form. Use symbolic notation and fractions where needed.) CO = Make a graph of the amount of chlorine remaining that covers the first 30 hours of the cleaning process if there are initially 50 grams in the water. (Enter expression in terms of f to graph.)Make a graph of the amount of chlorine remaining that covers the first 30 hours of the cleaning process if there are initially 50 grams in the water.
