Step 1: Perform the horizontal line test as the first step. Move a horizontal line from the graph's bottom to its top to accomplish this. The graph fails the horizontal line test and does not have an inverse if the horizontal line touches two or more points on the graph at any given time. Continue to Step 2 if the graph passes the horizontal line test.
Step 2: Determine the given function's domain and range in step two.
Step 3: A square root function is the inverse of a quadratic function. We switch the domain and range in order to graph the inverse. The graph has the same structure but has been rotated to have the original function's domain and range switched.
A quadratic function is the inverse of a square root function. We switch the domain and range of the original function to get the graph of the inverse. In other words, the range of the inverse quadratic function is the domain of the square root function. The domain of the inverse quadratic function is the range of the square root function. The graph's geometry is the same, but it has been rotated to give it the right domain and range.

Sooo yeah umm..... I need help.
Answer:
[tex]\mathrm{Slope } = \dfrac{2}{3}[/tex]
Step-by-step explanation:
To find the slope take any two convenient x, y value combo.
Find the difference between the two y-values(we call it rise).
Find the difference in the corresponding x-values (we call this the run)
[tex]\dfrac{rise}{run} = slope[/tex]
Take points (3, 1) and (6,3). I could choose any two points but working with positive numbers makes it easier
Rise = 3- 1 = 2
Run = 6 - 3 = 3
[tex]\mathrm{Slope } = \dfrac{2}{3}[/tex]
Just for the heck of it let's take two other points to make sure we haven't goofed
Take points (-1, - 5/3) and (1, -1/3)
rise = -1/3 - (-5/3) = -1/3 + 5/3 = 4/3
run = 1 - (-1) = 2
rise over run = 4/3 ÷ 2 = 4/3 x 1/2 = 2/3

For the given right triangle, L = 66°, LK = 3.56, and the hypotenuse, LM = 8.75.
What is right triangle?A right triangle, right-angled triangle, or more formally an orthogonal triangle—previously known as a rectangled triangle—is a triangle with one angle that is a right angle (i.e., a 90-degree angle), meaning that two of its sides are perpendicular. The foundation of trigonometry is the relationship between the sides and other angles of a right triangle.
The hypotenuse is the side that faces the right angle (side c in the figure). Legs are the sides that are next to the right angle (or catheti, singular: cathetus). Side a can be thought of as the side that is adjacent to angle B and opposite to (or opposite) angle A, whereas side b is the side that is adjacent to angle A and opposite to angle B.
Given a right triangle with base = 8 and an angle = 24°
Using angle sum property of triangle
24 + 90 + angle L = 180
L = 66°
Using Sohcahtoa
Tangent: tan(θ) = Opposite / Adjacent
tan(24°) = LK/8
0.445 = LK/8
LH = 8 × 0.445
LK = 3.56
LM = [tex]\sqrt{MK^2 + LK^2}[/tex]
LM = [tex]\sqrt{8^2 + 3.56^2}[/tex]
LM = 8.75
Thus, For the given right triangle, L = 66°, LK = 3.56, and the hypotenuse, LM = 8.75.

What does represent? index of refraction index of reflection angle of incidence angle of refraction.
The figure represents the angle of refraction
The angle of refraction is represented by the angle θ2
Light rays that are refracted change their direction as they travel through different media. Light changes direction when it travels from one medium to another.
The refracted beam will bend toward the normal if the incident light is moving from a less dense to a denser material. Here, the angle of refraction (hence, "r") is always smaller than the angle of incidence. (In line with the diagram)
Similar to this, the refracted ray will bend away from the normal if the incident light is moving from a denser medium to a less dense material. In this situation, the angle of incidence is never greater than the angle of refraction, or "r."

How do you find the mean value of a Class 10?.
The mean is dividing the sum of all values in a data set by the number of values.
Average is another word for "mean." For instance, if we say that the average height of the 9th grade class is 150 cm, it signifies that this is the mean of all of the kids' heights. The statistical notion of mean, which is employed in a variety of financial areas and corporate appraisal, has significant financial implications. The three statistical measurements of a data set's central tendency are mean, median, and mode.
The mean, which measures the central tendency of the data, is the average or computed central value of a set of numbers. The statistical metric known as central tendency identifies the complete collection of data or distribution by a single value. It offers a precise description of the entire set of facts. The ratio of the sum of all observations to the total number of observations is another way to define the mean in statistics.

How do you sketch the graph of a function of two variables?.
A two-variable function's graph can be thought of as a surface in three dimensions.
The points (x, y, f(x, y)) where x and y are in the domain make up the graph of z=f(x, y). You can fine-tune the shape of the surface by drawing the curve k=f(x, y) in the plane z=k for different values of k. For instance, we're trying to comprehend the graph of z=f(x, y)=x2+y2. Keep in mind that k=f(x, y) is a circle for k>0 and since 0=x2+y2 implies that x=y=0.
Additionally, it is symmetric in relation to the z axis. We have a parabola for x=k or y=k. As a result, the graph represents the revolution of the parabola z=x2 over the z axis (see Thomas, math).

Late one night a burglar got into one of the vault in Fort Knox and he tole a big ack of gold coin. On hi way out, he wa topped by one of the guard who aw him tealing the bag. Fortunately for him, the burglar wa able to negotiate a deal with the guard and offered him half the money he had taken, plu an extra $2,000 thrown in. Jut a he wa walking away, thinking he had gotten away he wa topped by a econd guard who took the ame bribe: Half the money with an extra $2000 thrown in. Jut a he wa about to leave , he wa topped by a third guard who let him go only after receiving half of all the burglar had left with $ 2,000 extra thrown in. By the time he left he had mixed emotion. After all he did leave with $9,000 more than he had when he arrived and he wa able to ecape. But he thought of all the money he left behind. How much did he teal in the firt place?
Therefore, the burglar's initial theft was $12,000.
To begin, we may express the data in the problem using algebra.
Let x represent the original sum that the burglary victim took.
The thief was left with x/2 + 2000 after giving the first guard the other half of the money plus $2,000, according to the issue.
He had (x/2 + 2000)/2 + 2000 when he gave the same sum to the second guard.
He also handed the third guard the same amount, leaving him with
((x/2 + 2000)/2 + 2000)/2 + 2000.
However, because we are certain that he left with $9,000 more than when he came, we may state:
((x/2 + 2000)/2 + 2000)/2 + 2000 = x + 9000
We can now determine x:

What is midpoint?Midpoint refers to a point that is in the middle of the line joining two points. The two reference points are the endpoints of a line, and the midpoint is lying in between the two points. The midpoint divides the line joining these two points into two equal halves. Further, if a line is drawn to bisect the line joining these two points, the line passes through the midpoint.
The midpoint formula is used to find the midpoint between two points whose coordinates are known to us. The midpoint formula is also used to find the coordinates of the endpoint if we know the coordinates of the other endpoint and the midpoint. In the coordinate plane, if a line is drawn to connect two points (4, 2), and (8, 6), then the coordinates of the midpoint of the line joining these two points are ({4 + 8}/2, {2 + 6}/2) = (12/2, 8/2) = (6, 4).

b = 11 c = 6.5Step-by-step explanation:
1) 2(3b + 6) = 78, value of b?
→ 2(3b + 6) = 78
→ 6b + 12 = 78
→ 6b = 78 - 12
→ 6b = 66
→ b = 66/6
→ [ b = 11 ]
Hence, the value of b is 11.
2) -2(6c - 3) = -72, value of c?
→ -2(6c - 3) = -72
→ -12c + 6 = -72
→ -12c = -72 - 6
→ -12c = -78
→ c = (-78)/(-12)
→ c = 78/12
→ [ c = 6.5 ]
Hence, the value of c is 6.5.
