The amount of a radioactive element A at time t is given by the formula A(t) = Aoekt, + BC Relaunch to update: PREVIOUS ANSWERS ASK YOUR TEACHER PRACTICE ANOTHER where A is the initial amount of the element and k < 0 is the constant of proportionality which satisfies the equation (instantaneous rate of change A(t) at time t) = KA(t). Use the formula given above to express the amount of Carbon-14 left from an initial N milligrams as a function of time t in years. (Round k to six decimal places.) A(t) = 2.718280 mg Part (b) Find the percentage remaining. What percentage of the original amount of Carbon-14 is left after 10,000 years?
