What characteristics change during rigid transformations?
During rigid transformations, the shape, size, and orientation of an object remain the same, while its position in space changes. This means that the distance between any two points on the object remains constant, as does the angle between any two lines. Additionally, the orientation of the object's axes (length, width, and height) remain the same.
What are transformations, exactly?Transformations are a general term for four different methods of changing the location and/or shape of a point, line, or geometric figure. The shape of the object is revealed in its pre-image, while its final form and position are revealed in the image following transformation.
What is a good example of transformation?A transformation is characterized by a significant alteration in appearance or form. Your life may change as a result of a significant event, such earning your driver's license, beginning college, or getting married. A significant, abrupt transformation is called a metamorphosis.

Use the Law of Cosines to find the values of x°and y°. Round to the nearest tenth.
The value of x and y° are 29.1 and 76.6°.
What is rounding to tenth?
Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5.
The length of sides of the triangle are x, 35, and 40.
Assume that AB = c = x, BC = a = 35, and AC = b = 40
m∠C = 45° and m∠B = y°.
Cosine law:
c² = a² + b² - 2ab cos C ....(i)
b² = a² + c² - 2ac cos B ....(ii)
a² = b² + c² - 2bc cos A ....(iii)
Putting a = 35, b = 40, c = x, and C = 45° in law (i)
x² = 35² + 40² - 2×35×40 cos 45°
x² = 2825 - 2800 × (1/√2)
x = 29.07
x = 29.1 (nearest tenth)
Putting a = 35, b = 40, c = 29.1, and B = y° in law (ii)
40² = 35² + 29.1² - 2×35×29.1 cos y

How do you find the vertical asymptote and removable discontinuity?
To find the vertical asymptote, look for the values of x where the denominator of a function equals 0. To find the removable discontinuity, look for the values of x where the numerator of a function equals 0.
Vertical asymptotes are x-values where the denominator of a fraction is equal to 0. To find the vertical asymptote, we need to set the denominator equal to 0 and solve for x. This will give us the x-values where the graph of the function has a vertical asymptote. Removable discontinuities are x-values where the numerator of a fraction is equal to 0. To find the removable discontinuity, we need to set the numerator equal to 0 and solve for x. This will give us the x-values where the graph of the function has a removable discontinuity. In both cases, once we have the x-values, we can plot the graph of the function and see where the vertical asymptote and removable discontinuity are located. We can also use these x-values to determine the behavior of the function in the vicinity of the vertical asymptote or removable discontinuity.

Can you justify that all sides and all angles are equal in a equilateral triangle?
If the given triangle has all three sides as congruent and the angles are same then the triangle is an equilateral triangle.
We will use the figure given below to prove the triangle as an equilateral triangle.
In the above figure,
Given, vertices of a triangle are A(X1, Y1), B(X2, Y2), and C(X3, Y3).
According to the properties of the equilateral triangle, the sides of an equilateral triangle should be equal in measure.
So, we use the distance formula:
d = √((x2 - x1)^2+(y2 - y1)^2 to verify if all three sides are congruent and equal to each other
If AB = BC = CA.
⇒ √((x(2) - x(1))^2 + (y(2) - y(1))^2) = √(x(3) - x(2))^2 + (y(3) - y(2))^2 = √(x(1) - x(3))^2+ (y(1) - y(3)) ^2
If the given triangle satisfies the above condition then the triangle is an equilateral triangle.
If the given triangle has all three sides as congruent then the triangles angles are also equal.

Answer:Slope is 1.5, and the y-intercept is -1
Step-by-step explanation:
So in order to get the slope and y-intercept, you have to put the equation in slope form, y=mx+b
Here’s the work for it
15x-10y=10
-15x -15x
-10y=-15x+10

What is the best example of discontinuity?
The best example of discontinuity is a graph of a function with a "hole" or "jump" in it, where the value of the function suddenly changes without any gradual change.
Discontinuity occurs when a graph of a function has an abrupt change, either in the form of a "hole" or "jump" in it. In a graph of a continuous function, the values gradually change in a smooth manner. However, with a graph of a discontinuous function, the function suddenly changes without any gradual transition. This sudden change is often caused by a discontinuity in the domain or range of the function. For example, a discontinuity may occur where a function is undefined or has an undefined limit. Graphically, this is usually illustrated as a gap or jump in the graph of the function. This type of discontinuity is known as a removable discontinuity, since it can be removed by redefining the function at the point of discontinuity. Other types of discontinuity include infinite discontinuity, which occurs when the graph of a function approaches either positive or negative infinity, and jump discontinuity, which occurs when the graph of a function jumps from one value to another without any transition.

How do I know my SSS or SAS?
The triangles are congruent if all three sets of comparable sides are present. The side-side-side shortcut is a congruence technique (SSS). Side-angle-side (SAS), which uses two sets of sides and an angle between them that is known to be congruent, is another shortcut.
SSS, which stands for "side, side, side," denotes that there are two triangles with identical angles on all three sides. The triangles are congruent if their third sides are the same as those of another triangle. The triangles are congruent if two pairs of corresponding angles and the included sides are both true. This standard is called angle-side-angle (ASA).
Angle-angle-side (AAS) is another criterion that takes into account the congruence of two pairs of angles as well as the non-included side. SSS stands for "side, side, side," which signifies that we have two triangles with equal sides on all three sides. SAS, ASA, and AAS are acronyms for these rules. "Side, Angle, Side" stands for two triangles whose two sides and one included angle are known to be equal.

What is meant by continuity of a function explain with an example?
Continuity of a function is when the function is continuous over the range of its domain. An example is a function f(x) = x^2, which is continuous over its domain of x∈R.
Continuity of a function is when the function is continuous over the range of its domain. A function is continuous if the graph of the function is a single, connected curve with no breaks or gaps. This means that for any point on the curve, the function is non-discontinuous. An example of a continuous function is f(x) = x^2, which is continuous over its domain of x∈R. This means that, no matter what value is put into the function, the output will always be a single value and the graph of the function will be a single, connected line. This is because the function is continuous over its entire domain, and therefore there are no breaks or discontinuities in the function. This is an example of continuity of a function.

find the distance between the points R(a+b,a-b) and S(a-b,a+b)
Answer:
The distance between the points R(a+b,a-b) and S(a-b,a+b) is 2*sqrt(2)*sqrt(a^2+b^2).
Step-by-step explanation:
To find the distance between the two points, we can use the distance formula:
distance = sqrt((x2-x1)^2 + (y2-y1)^2)
Plugging in the coordinates of the two points, we get:
distance = sqrt((a-b-a-b)^2 + (a+b-a+b)^2)
Simplifying, we get:
distance = sqrt(2*(a^2 + b^2))
Multiplying both sides by sqrt(2) gives us:
distance = 2*sqrt(2)*sqrt(a^2+b^2)
Therefore, the distance between the points R(a+b,a-b) and S(a-b,a+b) is 2*sqrt(2)*sqrt(a^2+b^2).
How to find the angle of a triangle given 3 sides and 1 right angle?
When the two sides and one angle of a triangle are given then we can find out the other two remaining angles by the law of sins.
Law of Sin :
In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
According to the law of sine s
[tex]\frac{sina}{A}[/tex] = [tex]\frac{sin b}{B}[/tex]
[tex]\frac{sin90}{A}[/tex] = [tex]\frac{sin b}{B}[/tex] ( since it is given that one angle is 90 degrees)
[tex]\frac{1}{A}[/tex] =[tex]\frac{sin b }{B}[/tex]
sin b = B/A
b = [tex]sin^{-1}[/tex](B/A) where B and A are sides of the triangle and known values.
Remaining angle c = 180- [tex]sin^{-1}[/tex](B/A)
