A wooden artifact from an ancient tomb contains 50 percent of the carbon-14 that is present in living trees. How long ago was the artifact made? (The half-life of carbon-14 is 5730 years.) Round your answer to the nearest year.
The artifact was made years ago.
Answer
Final Answer: The artifact was made \( \boxed{5730} \) years ago.
Step 1 ：Given that the wooden artifact from an ancient tomb contains 50 percent of the carbon-14 that is present in living trees.
Step 2 ：This means that one half-life of carbon-14 has passed since the artifact was made.
Step 3 ：The half-life of carbon-14 is given as 5730 years.
Step 4 ：Therefore, the age of the artifact is equal to the half-life of carbon-14.
Step 5 ：Substitute the given values into the equation.
Step 6 ：Let half_life_of_carbon_14 = 5730
Step 7 ：So, age_of_artifact = half_life_of_carbon_14 = 5730
Step 8 ：Final Answer: The artifact was made \( \boxed{5730} \) years ago.
