All living organisms maintain a constant level of radioactive Carbon-14. Once the organism dies, the Carbon-14 decays according to the function below, where t is the number of years since death and A0 is the amount of Carbon-14 present at death. A(t)=A0 x e^-0.000124t The model is considered accurate up to 100,000 years. Dre has a sample of bone from an ox that he thinks is 46,000 years old, but he wants to find its actual age to be sure. He knows the ox should have had 300 milligrams of Carbon-14 at the time of death. What is the domain of the function A(t)?

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

Answer! if you don’t mind, can you explain
