Hello, I just need help for the answers to (d) and (e). Please read the questions carefully and use the model I made in (a). You will need a graphing calculator to solve. Please double check work. Thank you!!

A radioactive substance has a dally continuous decay rate of 1,779%. Suppose that a lab technician has an initial amount of 14.5 grams of this substance. (a) Create a model R (d) that computes the amount of the radioactive substance remaining after w weeks since the initial measurement. R (d) = 14.5e-0.01779d (b) Determine how much of the substance remains after 35 days since the Initial measurement. Give your answer correct to three decimal places and select the correct units. Answer: 7.779 grams (c) Determine the half-life of the radioactive substance. Give your answer correct to three decimal places and select the correct units. Answer: 38.9627 days (d) Determine the account's hourly decay rate. Give your answer as a percentage correct to five decimal places. Answer: % X (e) Determine the account's weekly decay rate. Give your answer as a percentage correct to five decimal places. Answer: % X
