Given:

The given function is:

[tex]f(x)=\sqrt{x-7}[/tex]

To find:

The value of x that is in the domain.

Solution:

Domain is the set of input values.

We have,

[tex]f(x)=\sqrt{x-7}[/tex]

We know that the square root is defined for non negative values. So,

[tex]x-7\geq 0[/tex]

[tex]x\geq 0+7[/tex]

[tex]x\geq 7[/tex]

Thus, the domain of the given function is all real number that are greater than or equal to 7.

In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, [tex]x=8[/tex] is in the domain of the given function.

Therefore, the correct option is A.

Answer: 100+20h=x

Step-by-step explanation:

100 for the cost of the window Plus $20 times amount of hours the person does i equal the total amount you want to get which is x

Answer:

100 + (20 x H)

Step-by-step explanation:

100 dollars plus the amount paid for each hour of labor, so it would be 20 x H. Altogether it should be 100 + (20 x H).

Answer:

$72

Step-by-step explanation:

I did 36 x 2. I did not subtract the -6 for the prize money because it says not to.

Answer:

$72

Step-by-step explanation:

You are trying to determine how much money the school will take in before giving out prize money. Knowing this, you can actually ignore the $6 that the winner will get because you are not worried about giving out the prize money yet. You are only worried about how much you will make before the prize money.

So, you can do simple multiplication to find the answer:

price per game * amount of people playing game = money made from games

$2 * 36 = x

$72 = x

Answer:

C

Step-by-step explanation:

sine uses opposite over hypotenuse

the opposite of x is 20 and the hypotenuse is 29

so the answer is 20/29

Step-by-step explanation:

So, we first see that there is a movie theatre that can hold 125 people and it is 2/5 full, so we would do 2/5 x 125 = 50 then we would do 125 - 50 = 75

Answer:

8.11

Step-by-step explanation:

4+4+7+13+12+9 = 49

divide that by 6

========================================================

Explanation:

Sort the data set to go from {4,4,7,13,12,9} to {4,4,7,9,12,13}

Next, cross off the first and last items to get this smaller set: {4,7,9,12}

Repeat the last step to get this even smaller set: {7,9}

We can see that 7 & 9 are tied for the middle most positions. Add them up and divide by 2 to find the midpoint

(7+9)/2 = 16/2 = 8

The median is 8

Answer:

Quadrant IV or D

Step-by-step explanation:

It is Quadrant IV or D, since it is a positive x (meaning it must be 1 or 4) and it has a negative y (so 3 or 4). You then find the common answer which is 4 or IV.

Answer:

13.95 cm

Step-by-step explanation:

the volume of the cone =

⅓× π r². h = 180 π

⅓×π r²×15 = 180 π

(eliminate π)

=> 5r² = 180

r² = 180/5 = 36

r=√36 = 6 cm

the volume of the sand = ½×4/3 π r³

= ⅔× π ×6³ = 144π cm³

the ratio of the volume :

144π/180π = 0.8

so the value of h = ³√0.8 x 15 = 0.93× 15

= 13.95 cm

Answer:

Step-by-step explanation:

1) a variable term contains a variable. If x is  a variable

5x is an example of a variable therm

2) a constant therm is not a variable

3 is an example

3) for example when a number multiply a sum or a difference between a constant and a variable

Example:

2(x-3) = 5(x+4)

4) one solution: only if x is equal to 0 the equation is true

5) no solution: the equation can’t be true for ever value of the variable

6) infinite solutions: the equation is ever true for every value of the variable

Answer: [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Rate of change are typically found using [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1} }[/tex].

[tex](x_{1}, y_{1}) = (-2, 3)\\(x_{2}, y_{2}) = (2, 5)\\\\\frac{5-3}{2-(-2)} =\frac{2}{2+2} =\frac{2}{4} =\frac{1}{2}[/tex]

Therefore, the rate of change(aka slope) is [tex]\frac{1}{2}[/tex].

Answer: 4[tex]\sqrt{3\\}[/tex]

Step-by-step explanation:

It is because to get rid of radical of 48, because you factor 48 and it comes out to be 12 and 4, factor of 4 is 2 x 2. Factor of 12 is 6 x 2. Simplify the 6 to

3 x 2. You find the pair and the ones that have a pare become one and go outside of the radical sign on the left. 2 has 2 pairs so it is only 2 x 2 = 4. So 4 goes outside of the radical sign. Then the number that is alone with no pair is 3 so you put the number 3 inside the radical sign.

4[tex]\sqrt{3}[/tex] is your answer.

Given:

A figure of a right angle triangle.

To find:

The length of BC.

Solution:

In a right angle triangle,

[tex]\tan \theta =\dfrac{Perpendicular}{Base}[/tex]

In the given triangle,

[tex]\tan A =\dfrac{BC}{AC}[/tex]

[tex]\tan 23^\circ =\dfrac{BC}{6}[/tex]

[tex]0.42447\times 6 =BC[/tex]

[tex]2.54682 =BC[/tex]

Approximate the value to the nearest hundredth.

[tex]BC\approx 2.55[/tex]
