Carbon14 is a radioactive substance that decays over time. One of its important uses is in dating relatively recent archaeological events. In the following table, time t is measured in thousands of years, and C=C(t) is the amount, grams, of carbon14 remaining. t = Thousands of years 0 5 10 15 20 C = Grams remaining 7 3.82 2.09 1.14 0.62 Carbon14 unstable (radioactive) (a) What is the average yearly rate of change of carbon14 during the first 5000 years? (Round your answer to six decimal places.). g/yr (b) How many grams of carbon14 would you expect to find remaining after 3438 years? (Round your answer to two decimal places.) 9 (c) What would you expect to be the limiting value of C? Carbon14 is a radioactive substance that decays over time.
