Many patients get concerned when a test involves injection of a radioactive material. For example for scanning a gallbladder, a few drops of Technetium-99m isotope is used. However, it takes about 24 hours for the radiation levels to reach what we are exposed to in day-to-day activities. Below is given the relative intensity of radiation as a function of time. t(hrs) 0 1 3 5 7 9 R 1.000 0.891 0.708 0.562 0.447 0.355 The relative intensity is related to time by the equation R=A e^(Bt). Find constant using the least square method. (Correct to 4 decimal places)
