<h2>Answer</h2>
<h2>Explanation</h2>
Remember that the square root function is not defined, in the set of real numbers, for negatives values, so its radicand (the thing inside the square root) must be zero or bigger than zero. In other words, to find the domain of a square root function, you should set the thing inside the radical bigger or equal to zero and solve for x. Let's find the domain of each one of our functions:
For
The thing inside the square root is 
, so we are setting that bigger or equal than zero and solve for x to find the domain of the function:
domain
For 
domain
For 
and 
domain
As you can see, the only one that has the domain is the first choice.
Answer:
Step-by-step explanation:
Percent literally means hundredth
%=p/100 so
p/100=3/10 so multiply each side by 100
p=300/10
p=30%
p/100=2/50 multiply each side by 100
p=200/50
p=4%
So you can see the pattern here, multiply the fraction by one hundred and you have the ‘percentage’.
Answer:
x = -12,
Step-by-step explanation:
-1 + 5/4x = -16
5/4 x = -16 + 1
5/4 x = -15
x = -15 * 4/5
x = -12.
Answer:
Step-by-step explanation:
She makes $325 a week, so go to the 8th row, for weekly income of $300 to $400. She claims 2 exemptions, so go to the third column labeled 2. The value is 2. That means the $2 is withheld from her paycheck on top of the 6.25% for FICA. The total is therefore:
$2 + (0.0625) ($325)
$22.3125
Rounded to the nearest cent, that's $22.31.
