Help me please with complete solution

12) Carbon 14 Is a common form of carbon which decays over time. The amount of Carbon 14 f(t) = 109'\". contained in a preserved plant is modeled by the equation Time In this equation is measured in years from the moment when the plant dies (t=0) and the amount of Carbon 14 remaining in the preserved plant is measured in micrograms (a microgram is one millionth of a gram). So when t=0 the plant contains 20 micrograms of Carbon 14. a. The half-life of Carbon 14, that is the amount of time it takes for half of the Carbon 14 to decay. is appmximately 5730 years. Use this information to nd the constant c. Solution: Final answer: b. If there is currently one microgram of Carbon 14 remaining in the preserved plant, approximately when did the plant die? Solution: Final
