<span>A 2% solution of chlorohexidine added to 126 oz of water. The total oz 128.
Solute: chlorohexidine, 2%=0.02
solvent: water (0%)
Concentration, C, volume V
CV=c1v1+c2v1
128C=0.02*2 + 0.00*126 = 0.04
Concentration
C=0.04/128 = 0.0003125 = 0.03125%</span>
Answer: D
Step-by-step explanation:
The graph is narrower, so the coefficient of
has an absolute value more than 1.
Also, because g(x) opens down, the coefficient of
is negative.
This leaves D as the answer.
quotient is 6 and the remainder is 23
By looking at the statement I derived,
32 = 8 * 4
