A half life means that half the sample decays.
If the sample size is 1 , then after one half life there would be x * 1/2 = 1/2 of the sample left.
For the 2nd half life, multiply 1/2 by 1/2 to get 1/4.
So after 2 half lives, there is 1/4 of the sample left, which means 3/4 of the sample decayed.
The answer is 3/4
In this case the two equations<span> describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) will satisfy the </span>equation<span> of either line. Thus the pair (x, y) is the one and only </span>solution to the system of equations<span>.</span>
Answer:
Step-by-step explanation:
-4 ( 4v - u - 6 )
You will multiply -4 with everything in the parentheses.
-16v + 4u + 24
