The option D shows a function has a domain of all real numbers.
Which is the Domain of a Function?
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.
Letter A - [tex]y=\left(x+2\right)^{^{\frac{1}{4}}\:}[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]\left(x+2\right)^{^{\frac{1}{4}}\:}=\sqrt[4]{x+2}[/tex]
Therefore, the function domain is x [tex]\geq[/tex]-2.
Letter B - [tex]y=-x^{\frac{1}{2}}^{\:}+5[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]-x^{\frac{1}{2}}^{\:}+5=-\sqrt{x} +5[/tex]
x [tex]\geq[/tex] 0
Therefore, the function domain is x [tex]\geq[/tex] 0.
Letter C - [tex]y=-2\left(3x\right)^{\frac{1}{6}}[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]-2\left(3x\right)^{\frac{1}{6}}=-2*\sqrt[6]{3x}[/tex]
3x [tex]\geq[/tex] 0
x [tex]\geq[/tex] 0
Therefore, the function domain is x [tex]\geq[/tex] 0.
Letter D - [tex]y=\left(2x\right)^{\frac{1}{3}}-7[/tex], as you have an odd exponent, the results for y has no undefined points nor domain constraints. Thus,[tex]\left(2x\right)^{\frac{1}{3}}-7=y=\sqrt[3]{2x} -7\\ \\[/tex]
Therefore, the function domain is [tex]-\infty \: < x < \infty \:[/tex].

Consider the population of part-time college students. Suppose that 60% of this population is female. Here is the sampling distribution for the proportion of females in random samples of n students. The standard deviation is approximately 0.10. Lines indicate a distance of 1 and 2 standard deviations above and below the mean.
Answer:
The answer is "1.5".
Step-by-step explanation:
Given value:
[tex]p= 60 \% = \frac{60}{100}= 0.60\\\\\sigma_p = 0.10 \\\\\hat{p} =0.75[/tex]
testing the statistics:
[tex]Z= \frac{\hat{p} -p}{\sigma_p}\\\\[/tex]
[tex]=\frac{0.75-0.60}{0.10}\\\\=\frac{0.15}{0.10}\\\\=1.5[/tex]

Use the equation y = x - 2 and perform a reflection over the x-axis. Write an equation in 2
1
slope intercept form that represents the new line.
Answer:
So after reflecting over the x-axis, the equation is:
[tex]-y = x-2[/tex]
so the equation in the slope-intercept form
[tex]-y = x-2[/tex]
[tex]y=-x+2[/tex]
Here,
The slope = m = -1The y-intercept = b = 2Step-by-step explanation:
Given the equation
[tex]y = x - 2[/tex]
Reflecting over the x-axis inverts the sign of the y-coordinate, but the sign of the x-coordinate remains the same.
So after reflecting over the x-axis, the equation is:
[tex]-y = x-2[/tex]
Now, writing the equation in the slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so the equation in the slope-intercept form
[tex]-y = x-2[/tex]
[tex]y=-x+2[/tex]
Here,
The slope = m = -1The y-intercept = b = 2The sum of two numbers is 53 and the difference is 19. What are the numbers?
an open box of maximum volume is to be made from a square piece of material, 26 centimeters on a side,
Domain of the function is: 0 < x < 12.
Volume of the box = 4x(12-x)²cm^3
Volume of a cuboid:Volume is the measure of how much space a given substance takes up inside a closed, three-dimensional object. A cuboid's volume given by its length (l), breadth (b), and height (h) is as follows:
According to the given data:Side of square = 24cm
(a) Volume of the box
Let the squares used to create a box have a side of "x" cm.
so,
length will be = 2(12 - x)
Width will be = 2(12 - x)
Hight will be = x
Volume of the Square box (V) = l x b x h
= 2(12 - x) * 2(12 - x) * (x)
= 4x(12-x)²cm^3
(b) The domain of the function V(x)
We see that:
x is length, x >0
x cm of the side's length of 24 cm are removed from both ends.
so that 2x<24
Domain of the function is: 0 < x < 12.

I understand that the question you are looking for is:
An open box of maximum volume is to be made from a square piece of material, 24 centimeters on a side, by cutting equal squares from the corners and folding up the sides.
If V is the volume in cubic centimeters and x is the height of the box in centimeters, find V in terms of x. Determine the domain of the above function
Shayna enlarged a square photo by adding 10 inches to each side so it could be seen on a large poster. The area of the enlarged photo is 256 square inches. In the equation (x + 10)2 = 256, x represents the side measure of the original square photo.
What were the dimensions of the original photo?
pls hurry
4 inches by 4 inches
6 inches by 6 inches
10 inches by 10 inches
12 inches by 12 inches
Answer:
The correct answer is:
6 inches by 6 inches
Step-by-step explanation:
Given that
Area of Enlarged photo = 256 square inches
Let x be the side of original photo
then the equation for area of new enlarged photo will be:
[tex](x+10)^2 = 256[/tex]
We have to solve the given equation to find the side length of original photo
Taking square root on both sides
[tex]\sqrt{(x+10)^2} = \sqrt{256}\\x+10 = 16[/tex]
Subtracting 10 from both sides
[tex]x+10-10 = 16-10\\x = 6[/tex]
So the side length of original photo is 6 inches. The dimensions will be 6 inches by 6 inches.
Hence,
The correct answer is:
6 inches by 6 inches

when making a long trip, you should stop for a rest: about every four hours or two hundred miles only when you stop for meals and gasoline do not stop until you get to your destination about every two hours or one hundred miles submit answer
In order to keep the attention and reduce the risks that come with driving too much without a break, it is generally advised to take a break of at least 15 minutes every two hours and to limit your driving time to no more than eight hours per day during a long trip.
What is a long trip?
Driving over extended periods of time without rest can be quite dangerous, despite how alluring it may be on a road trip to do so in order to reach your goal as quickly as possible.Frequent breaks are essential to maintaining a high standard of safe, efficient driving since driving requires a lot of concentration, expertise, and control that is challenging to maintain for hours on end.In order to keep the attention and reduce the risks that come with driving too much without a break, it is generally advised to take a break of at least 15 minutes every two hours and to limit your driving time to no more than eight hours per day during a long trip.

Robin invested $1000 in a 12% simple interest savings deposit for 3
years. He also invested an equal amount in a 10% compound interest
savings deposit for 3 years. At the end of 3 years, how much more
interest did he get from the simple interest deposit?
Step-by-step explanation:
Lets find out,shall we?
Simple interest=(PRT)/100
=$1000×12×3)/100
=$360
Now for compound interest
A=P(1+R/100)^t
A=$1000(1+12/100)^3
A=$1404.928
so interest for compound interest=$(1404.928-1000)=$404.928
Clearly,Robin got more interest by compound interest than simple interest which business people understand lol.
Difference in interest=$404.928-360=$44.928

Given CAD is a right angle and AB is bisecting CAD and if DAB=(7x-4) find X
Answer:
7°
Step-by-step explanation:
Just a quick clarification, swap A and B on the diagram.
If CAD is a right angle, it is equal to 90°. Since AB is bisecting CAD, angles CAB and DAB are congruent(equal) and complementary(add up to 90) angles, and thus equal 45°. By the transitive property, if DAB = (7x - 4)° and also equals 45°, (7x - 4)° = 45°. So we can simply solve for x.
7x - 4 = 45
7x - 4 + 4 = 45 + 4
7x = 49
7x/7 = 49/7
x = 7

Answer:
I think it's answer choice A!
Step-by-step explanation:
The reason why I think that it is A is because of the given y values. The x values are consistent through all of the given choices, but if graphed, there is a distance of three units between the y-value of 4 and the y-value of 7. I personally like to use Desmos when it comes to trying to get a visual graph of coordinates. I hope this at least helped a little!
The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units, therefore, option (A) will be correct.
How to find the distance between two points?Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
The distance between with two points (x₁, y₁) and (x₂, y₂) is given as,
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
In option (A),
Points are (2,4) and (2,7).
The distance between them will be,
[tex]d = \sqrt {\left( {2 - 2 } \right)^2 + \left( {4 - 7 } \right)^2 }[/tex]
d = √(3²) = 3
Hence "The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units".
