Question

Cosmic ray bombardment of the atmosphere produces neutrons, which in turn react with nitrogen to produce radioactive carbon-14 point Radioactive carbon-14 enters all living tissue through carbon dioxide (via plants). As long as a plant or animal is alive, carbon-14 is maintained in the organism at a constant level. Once the organism dies, however, carbon-14 decays exponentially into carbon-12 point By comparing the amount of carbon-14 to the amount of carbon-12 comma one can determine approximately how long ago the organism died. (Willard Libby won a Nobel Prize for developing this technique for use in dating archaeological specimens). The half-life of carbon-14 is about 5730 years. In answering the following questions, assume that the initial quantity of carbon-14 is 500 milligrams. a. Construct an exponential function that describles the relationship between Upper A comma the amount of carbon-14 in milligrams, and t comma the number of 5730-year time periods.

Answer 1

I think I have the answer let me just double check my work okay!
