A wooden artifact from an ancient tomb contains 35 percent of the carbon-14 that is present in living trees. How long ago, to the nearest year, was the artifact made

the artifact was made about 8679 years ago

Step-by-step explanation:

Given the data in the question;

we know that, The half-life of carbon-14 is 5730 years.

Now using the following equation;

Final amount = (initial amount) 0.5

given that the tomb contains 35 percent of the carbon-14

meaning final amount / initial amount = 35% = 0.35

hence, from the equation;

0.35 =

x = 5730 ln(0.35) / ln(0.5 )

x = 8678.5 ≈ 8679 years

Therefore, the artifact was made about 8679 years ago

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
