Question

An archaelogist in Turkey discovers a

spear head that contains 53% of its
original amount C-14.

FIND THE AGE OF THE HEAD TO THE NEAREST YEAR

Answer 1

6349

Explanation:

Solve 0.53No = Noe^-0.0001t for T.

Divide both sides by No

0.53No = Noe^0.0001t

0.53 = e^-0.0001t

Take the log of both siddes

In 0.53 = In e^-0.0001t

Apply In e^x = x.

In 0.53 =-0.0001t

Divide both sides by -0.0001t to solve for t.

t=6,349
