Discontinuity function is an explanation of development that emphasizes sudden changes or shifts, rather than gradual progressions, in development. Examples include Piaget’s stages of cognitive development and Erikson’s psychosocial stages.

Discontinuity function is an explanation of development that emphasizes sudden changes or shifts, rather than gradual progressions, in development. This theory suggests that development does not occur in an orderly, linear fashion, but instead involves abrupt changes in which an individual moves from one distinct stage to the next. Examples of discontinuity theory include Piaget’s stages of cognitive development and Erikson’s psychosocial stages, which are made up of distinct stages of development that an individual must progress through before reaching the next stage. According to discontinuity theory, development is not a gradual, continuous process, but rather is made up of distinct stages with abrupt changes in between. This theory has been useful in helping to explain the development of various aspects of an individual, such as cognitive, social, and emotional development.

The ASA criterion might be the most appropriate, as it states that two triangles are congruent if two angles and the included side are congruent.

To use a congruence criterion in the given situation, you will need to determine which criterion is most appropriate based on the information provided. There are several congruence criteria that can be used to determine whether two triangles are congruent, including the Side-Side-Side (SSS) criterion, the Side-Angle-Side (SAS) criterion, the Angle-Side-Angle (ASA) criterion, and the Angle-Angle-Side (AAS) criterion.

In this case, the ASA criterion might be the most appropriate, as it states that two triangles are congruent if two angles and the included side are congruent. Given that ∠A=∠C=90∘ and AE=CB, you can use the ASA criterion to conclude that triangles AEB and CED are congruent.

The required value of the C in the algebraic measure of the angles is 61.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

here,
The property of the triangle states that the sum of the remote interior angles is equal to the exterior angle,
So, adding c - 18 and c -15 will be equal to c +28
c - 18 + c - 15 = c + 28

Answer:

The answer for the problem on the left is 70

The answer to the problem on the right is 120

Step-by-step explanation:

(n -2)180 is one formula to find the sum of the interior angles of a polygon.  n stands for the number of sides

(4-2)180

2(180

360

We know three of the angles we subtract them from 360 to find the missing angle

360-60-110-120 = 70

Right Problem:

We can find the bottom left and the bottom right angles by subtracting the exterior angle from 180.  A straight line has an angle measurement of 180.

180-60 = 120

180 - 50 = 130

Now we just need to find x.

(n-2) 180

(5-2)180

3(180) = 540    Subtract what we know

540 -50 - 130 - 120 = 240

The x's have the same value so 2402 is 120 .

The distance between the points (3 ,7) and (15 ,16) on a coordinate plane is 15 units.

In coordinate geometry, every point is denoted by definite coordinates since every point is situated at a fixed distance from the origin point (0,0). Any two points on a coordinate space are situated at a constant distance since their coordinates are fixed with respect to the origin. A line segment has two endpoints, and the coordinates of the endpoints help to determine the length of the line segment. Let us suppose (x1,y1) and (x2,y2) are the two points on a coordinate space then the distance between these two points is given by the distance formula as per the below:

            [tex]d = \sqrt{(x1 - x2)^2 + (y1 -y2)^2}[/tex]

given points are (3 ,7) and (15 ,16).

(x1,y1) = (3,7) and (x2,y2) = (15,16)

We know that two points on a plane have a constant distance in between them, and the distance formula gives the distance between these two points.

                  d =[tex]\sqrt{(x1 - x2)^2 + (y1 - y2)^2}[/tex]

              ∴  d = √(3 - 15)^2 + (7 - 16)^2

The graph of a two-variable inequality is the set of points that describe all solutions to the inequality.

The coordinate plane is split in half by a boundary line created by a linear inequality, with one-half representing the solutions to the inequality.

Step 1: Always begin by separating the variable y from the inequality's left side.

Step 2: Replace the symbol for inequality with that for equality.

Step 3: In the xy plane, graph the boundary line from step 2. You are creating the boundary line that would divide or cut the xy-plane into two sections in this stage.

Step 4: Shading one side or area of the boundary line is the final step.

Step 5: Use this optional step to check or confirm that you have shaded the boundary line's side appropriately.

The average of the absolute deviations from a central point makes up the average absolute deviation of a data collection.

It is a statistical summary of statistical variability or dispersion.

So, the sum of all the values:

8 + 9 + 12 + 15 + 16 + 20 + 24 + 30 + 32 + 34 = 200

A number of observations:

= 10

Formula: Mean = (sum of all observations)/(Total number of observations)

Now, calculate using the formula as follows:

Mean = (sum of all observations)/(Total number of observations)

Mean = (200 / 10)

Mean = 20

Now, we must determine how far the provided values are from the mean.

20 - 8 = 12

20 - 9 = 11

20 - 12 = 8

20 - 15 = 5

20 - 16 = 4

20 - 20 = 0

24 - 20 = 4

30 - 20 = 10

32 - 20 = 12

34 - 20 = 14

Formula:

Mean deviation = (sum of the distance of each value from mean) / (Total number of observations.)

Sum of each value's deviation from the mean = 12 + 11 + 8 + 5 + 4 + 0 + 4 + 10 + 12 + 14 = 80

Mean deviation = 80 / 10 = 8

Given logarithmic equation:

[tex]\log_{10}(x^{2}-4x)=2[/tex]

[tex]\textsf{Apply log law}: \quad \log_ab=c \iff a^c=b[/tex]

[tex]\implies 10^2=x^2-4x[/tex]

[tex]\implies x^2-4x=100[/tex]

Add the square of half the coefficient of the term in x to both sides of the equation:

[tex]\implies x^2-4x+\left(\dfrac{-4}{2}\right)^2=100+\left(\dfrac{-4}{2}\right)^2[/tex]

[tex]\implies x^2-4x+\left(-2\right)^2=100+\left(-2}\right)^2[/tex]
