Which function has the domain x>-11
Marat540 [252]
<h2>Answer</h2>

y=\sqrt{x+11} +5

<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 y=\sqrt{x+11} +5

The thing inside the square root is x+11, so we are setting that bigger or equal than zero and solve for x to find the domain of the function:

x+11\geq 0

x\geq -11   domain

For y=\sqrt{x-11} +5

x-11\geq 0

x\geq 11   domain

For y=\sqrt{x-5} -11 and y=\sqrt{x-5} +11

x+5\geq 0

x\geq -5   domain

As you can see, the only one that has the domain x\geq -11 is the first choice.

Can someone please write each fraction as a percent and tell me which operation they used? 1. 3/10 2. 2/50 3.7/20 4. 1/5 5.1/8 6
vesna_86 [32]

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’.

I'm so confused please helpppppppp<br><br> How is C correct please show your work
777dan777 [17]

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.
