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.
