Why is the square root of 4 only 2 and not 2?

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).

Answer:

The slope of the line described by the equation 15x – 10y = 10 is m = 15/10 = 1.5, and the y-intercept is b = 10/15 = 2/3.

Step-by-step explanation:

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

Now divide -10 on both sides

y=1.5x-1

Now that it’s in the right form, you can easily see the slope is 1.5 and the y-intercept is -1

The Frequency of graph is 3

The frequencies of each category are represented individually in a frequency graph; the frequencies of each category are shown cumulatively. By doing so, we are able to analyze the data's distribution in greater detail than we could have done by using a Frequency polygon and performing statistics.

A frequency polygon can also be used to display grouped data. This sort of line graph exists. The horizontal axis is a continuous scale, therefore the frequencies can be connected using straight line segments.

Looking at the graph we can see that the graph is oscillating between -3 and 3 and as frequency is a positive term taking modulus of this oscillation we get to know that the frequency is 3.

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.

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.

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.

y = 3x - 2 is an example of a linear function graph.

For graphing linear functions, there are three fundamental techniques. The first method involves tracing a line across a set of points that have been plotted. The second method makes use of the slope and y-intercept. Applying transformations to the identity function f(x)=x f(x) = x is the third step.

Those with a straight-line graph are considered to be linear functions. The following is the form of a linear function. a + bx = y = f(x). In the linear function there are one independent and one dependent variables . X is an independent variable, whereas Y is a dependent variable.

Example: The equation y = 3x – 2 depicts a linear function since it is a straight line in the coordinate plane. This function may be expressed as f(x) = 3x - 2 since y can be substituted with f(x).

To duplicate angle ABC, draw a line segment, position the compass on point A, and then draw an arc that intersects the line segment. Next, position the compass on point B, and then draw a second arc that intersects the first arc at a point on the line segment. Finally, position the compass on the point where the two arcs intersect, but without changing the width, and draw a third arc that intersects the line segment.

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.

Common instruments used to measure angles are:

1. Protractor

2.Compass

3.Digital Angle finder

4.Angle finder

5.Clinometer

6. Inclinometer

You can take the following actions to copy angle ABC:

Create a line segment that will serve as the foundation for the new angle you're going to create.

Draw an arc that crosses the line segment you produced in step 1 by positioning the compass on point A.

Draw a second arc that crosses the previous arc at a point on the line segment by setting the compass on point B.

Place the compass on the intersection of the two arcs without adjusting the compass's width, then create another arc that crosses the line segment.

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.

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.

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.
