Suppose that the half-life of kidney transplants is 13.3 years. (a) Create an exponential function to model the percentage K of kidney transplant recipients who have not rejected the kidney as a function o time t = 0 years.) OK = Ko(0.051) OK = Ko(-13.3) OK = Ko(1.949)' OK - Ko(-1.051) O K = K.(0.949) (b) Predict the percentage of kidney transplant recipients (as a %) who still have their transplanted kidney after 6 years. (Round your answer to 0.730 X % (c) How long, in years, will it take until the percentage of kidney transplant recipients still having their kidney drops to 35%? (Round your answ yr
