2. The age of a bone can be determined from the fraction of carbon-14 that remains in the bone. The age is calculated by using the formula A= -19000(log R), where A is the age in years and R is the fraction of carbon-14 remaining. Give answers to the nearest tenth. a. b. How old is a bone that has only 5% of its original carbon 14? Calculate the percent of carbon 14 remaining in a bone from an animal that died 400 years ago.
