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.

Don’t mind the Answer D I circle can someone explain the answer to me 25 point if no explanation and answer I flagged
Kruka [31]

Answer:

 (A) 49

Explanation:

Given that the fractions are in their simplest form. So below the denominator cannot be a multiple of 3, 4, 5.

Breakdown:

Looking at option A (49), it is not a multiple of 3, 4, 5. So k can be 49.

Option B (50) is a multiple of 5. An even number like 4 so can be simplified.

Option C (51) is a multiple of 3 so can be simplified more. 3/51 = 1/17.

Option D (52) is an even number like 4 so can be simplified. 4/52 = 1/13.

What is the value of x? Test is timed please help.
Darina [25.2K]

Answer:

x = 19

Step-by-step explanation:

A circle has a total of 360 degrees. Because central angles are congruent to the degree measures of their arcs, and because of vertical angles we can construct the equation :

5x+37+5x+37+3x-9-9=360

We can simplify this to :

8x+28=360

Subtract 28, divide 8, and x is 19
