thank you!

A. Assume that W/) denotes the mount of radioactive material in alsobelance at time r. Radioactive decay is then described by the differential equations -=-AW(r) with W(0) = W. . where a is a positive constant called the decay constant. 1) Give the solution to -=-ZW(1) with W(0) = W. 2) Assume that #10) = 123 g and #(5) - 20 g and that time is measured in minutes. Find the decay compuant 1
