Answer:
11
Step-by-step explanation:
2^3-(30/5)+9
First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:
P- parentheses
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
so 30/5 = 6 and plugged in is:
2^3-(6)+9
Next, we do exponents:
2^3 = 2x2x2 = 8
plugged back in:
8-(6)+9
Now, we do the math from left to right so:
8-6=2
2+9=11
11 is your answer
Formula for C - 14 dating:
Age = [ ln ( percent/100 ) / ln (1/2 ) ] * 5,730 =
= [ ln ( 0.00921 ) / ln ( 0.5 ) ] * 5.730 =
= [( - 4.68746 ) : ( - 0.6931478 )] * 5,730 =
= 6.7626 * 5,730 = 38,749.56 ≈ 39,000 ( rounded to the nearest thousand )
