5. The half-life of a certain radioactive material is 78 hours. An initial amount of the material has a mass of 790 kg. Write an exponential function that models the decay of this material. Find how much radioactive material remains after 18 hours. Round your answer to the nearest thousandth. (1 point) y = 1 ( 1 178" ; 0.107kg 790 y = 7901 (1) y = 2 1 4.953 0.2019 2.7183 4.3493 78x 790. 1 1 ; 0 kg ; 0.429 kg Oy=790178 ; 673.233 kg 6. Use the table feature on a graphing calculator to evaluate e¹6 to four decimal places. (1 point) 5. The half-life of a certain radioactive material is 78 hours.
