The value of the expression for the given values of a and b is -1

<h3>Evaluating an expression</h3>

From the question, we are to evaluate the given expression for the given values of a, b, and c

The given expression is

a + b

The given values are

a = 4,

b = -5,

and

c = -8

To evaluate the given expression for the given values of a and b, we will put the values of a and b into the expression,

That is,

a + b becomes

4 + -5

= 4 -5

= -1

Hence, the value of the expression for the given values of a and b is -1

A hiker discovers a skull that contains 41% of its original amount of C-14. Find the age of the skull to the nearest year
snow_tiger [21]
We need the half-life of C-14 which is 5,730 years.
Now, we will need a half-life equation:
elapsed time = half-life * log (bgng amt / ending amt) / log 2
We'll say beginning amount = 100 and ending amount = 41
elapsed time = 5,730 * log (100/41) / log 2
elapsed time = 5,730 * log ( <span> <span> <span> 2.4390243902 </span> </span> </span> ) / 0.30102999566
elapsed time = 5,730 * 0.38721614327 / 0.30102999566
elapsed time = <span> <span> </span></span><span><span><span>5,730 * 1.2863041851 </span> </span> </span>
<span>elapsed time = 7,370.523 years
