Answer: I think it’s neither
Explanation:
The line is parallel unless the slope is the same and with a different y-intercept
The line are perpendicular unless the one of the slope is the negative reciprocal of the other.
And both equation didn’t meet any of the requirement.
Answer:
$3.06
Step-by-step explanation:
1 kg = $27.54
27.54/9 kilogram
X= 14 + 9y over 2
y= -x - 7 over 6
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 (
