The exponential function P = 400 x 0.89 gives the amount in parts per million of PCBs in a contaminated sitem months after a cleanup process begins. (a) What is the weekly decay factor? Assume there are four weeks in each month. (Round your answer to two decimal places.) Find a formula that gives the amount P in parts per million w weeks after cleanup begins. OP = 400 x 3.56" OP= 400 x 0.94" P= 400 x 0.22 P = 400 x 0.63" O P = 400 x 0.97" (b) What is the yearly decay factor? (Round your answer to two decimal places.) Find a formula that gives the amount P in parts per million y years after cleanup begins. OP= 400 x 0.99 OP 400 x 0.25 OP 400 x 5.34 OP= 400 × 0.07% OP= 400 x 10.68
