what is YZ?
enter your answer as a decimal in the box.
The midsegment postulate tells you YZ = (1/2)VX, so is
... YZ = (36.8 in)/2 = 18.4 in
Answer:
18.4 inches.
Explanation:
In order to solve this you have to remember that when a straight line parallel to the side of the triangle cuts the triangle the resultant smalle triangle is similar to the original and will save its proportions, in the image you can see that all of the segments on each side measure the same, meaning that the segment X-W will measure 4 units, and the segmetn ZW will measure 2, with this reference we can solve witha rule of three:
XW/ZW=XV/ZY
4/2=36.8 inches/ZY
ZY=36.8*2/4=18.4 inches

If ST is reflected across the line y=x, what is the new coordinate point of S'?
A. (5,2)B. (-5,-2)C. (-2,-5)D. (2,5)
Answer:
B. (-5,-2)
Explanation:
When a point is reflected across y = x, we only need to switch the x and y values of the old coordinates to get the new ones. S is at (-2,-5), so by switching the x and y values, we can find that the S' is at (-5,-2).
Triangle ABC and Triangle XYZ are similar. If angle A=30 and angle B=45, what can you conclude?
A. Triangle XYZ is acute.
B. Triangle XYZ is isosceles.
C. Triangle XYZ is right.
D. Triangle XYZ is obtuse.
The given angles sum to less than 90°, so the remaining angle must be more than 90°. (The total of all angles is 180°.) Triangle ABC has an angle greater than 90°, so is obtuse. Since the triangles are similar, their corresponding angles are congruent. Hence ...

in the diagram of a roof truss, what is the length of the collar tie, assuming it is placed at the midpoint of the rafters and the distance between the wallplates is 6.08 M?
A. 3.04 B. 6.08 C. 12.16 D. not enough information
If the length of the rafter includes the amount it overhangs the wall, saying the collar tie is at the midpoint of the rafter does not locate it with respect to the walls. Then the appropriate choice is ...
... D. not enough information
_____
If the midpoint of the rafter is taken to be the point halfway between the wall and the peak of the roof, then the midsegment postulate applies. The length of the collar tie is half the distance between the walls, hence ...
... A. 3.04 m
In a roof truss, the collar tie is placed at the midpoint of the rafters. The collar tie divides the total distance between the wallplates (6.08 Meters) into two equal parts. Therefore, the length of the collar tie is 3.04 Meters.
Explanation:In a roof truss, the collar tie is typically placed at the midpoint of the rafters. Given that the distance between the wallplates is 6.08 Meters, and the collar tie is at the midpoint, it would divide this total length into two equal parts. Therefore, the length of the collar tie would be exactly half of this total distance. Calculating this, 6.08 Meters divided by 2 gives us 3.04 Meters. So, the correct answer to the question is option A. 3.04 Meters.

explain why the quotient rule is used to determine the derivative of tan x and cot x
The quotient rule is used to find the derivative of a ratio between two functions. It is used in the case of tan(x) and cot(x) because tan(x) can be written as [tex]\frac{sin(x)}{cos(x)}[/tex] (so f(x) = tan(x) is really f(x) = [tex]\frac{sin(x)}{cos(x)}[/tex]). Similarly, cot(x) can be written as [tex]\frac{cos(x)}{sin(x)}[/tex], so the quotient rule also applies.

How does the psychoanalytic theory from Freud explain crime?
The psychoanalytic theory from Sigmund Freud explain that crime was done because of the unconscious mind of an individual. The theory believe that we are born as blank slates and the things that happen to us in the early years of life will determine if we are capable to develop criminal behavior. This means that our criminal action is based from our specific formative childhood influences.
In each question,line k is parallel to l, and line t intersects k and l. Based on the diagrams, which statement is true?
Answer:
A
Explanation:
The value of x is 79° because opposite exterior angles of parallel lines intersected by a transversal are congruent.
A transversal cuts two lines, and those lines are said to be parallel only if the corresponding angles are congruent.Thus, option A is correct.
What line k is parallel to l, and line t intersects congruent?When a transversal intersects two parallel lines, each pair of internal angles on each side is supplementary, or they sum. The opposite angles created by the junction of two lines are known as vertical angles or vertically opposite angle.
Alternate Exterior Angles are congruent if a transversal intersects two parallel lines. Transversal that cut two parallel lines provide matching angles that are congruent.
The pairs of angles inside the two lines and on either side of a transversal that divides two lines are referred to as the alternate interior angles.
Therefore, When a transversal divides two parallel lines, the resulting alternate interior angles are congruent.

Answer: d. Albert Bandura
Albert Bandura believe that we do not need to directly be reinforced or punished to learn for we are likely imitate those people similar to us. If a child imitates a model’s behavior and the consequences are rewarding, the child is likely to continue performing the behavior and her behavior has been reinforced without punishment needed.
Moreover, a child will behave in a way which it believes will earn approval to her/his parents because a child desires approval and will also take into account of what happens to other people when deciding whether or not to copy someone’s action.
Which pairs of figures are similar polygons?
The only pair of similar figures is BDHV and GNEF, the trap-ezoids at the bottom.
_____
Similar figures have both same-size angles and same-ratio sides.
Comparing ADLH to JBEK, we find AH/JK = 18/9 = 2, but LD/EB = 24/16 = 1.5. The side ratios differ (even though the angles are marked as congruent). The figures are not similar. (and the angles cannot be congruent as marked)
Comparing WHAT to SKGE, we find WT/TA = 40/22 ≈ 1.8182, and SE/EG = 16/10 = 1.6. The side ratios are different, so the figures are not similar.
Comparing DEF to ABC, we find the angles are different, so the figures are not similar.
Comparing BDHV to GNEF, we find the corresponding angles are all marked as congruent and the side ratios are all 18/12 = 21/14 = 33/22 = 3/2, the same. These figures are similar.

In the reading The liberal Arts in an Age of Info-Glut by Todd Gitlin, What is the purpose in quoting nineteenth-century critic Alexis de Tocqueville(para.5)?
Todd Gitlin emphasized the significance of promoting liberal arts in the information age by quoting the nineteenth-century critic Alexis de Tocqueville.
His issues on media and technology imply that students should study subjects like history, philosophy, literature, music, and language that are truly enduring in our society.
Furthermore, Todd Gitlin echoes Alexis de Tocqueville's insight that sensational emotions rather than pleasure might be evoked by popular culture. Todd Gitlin quoted the nineteenth-century critic Alexis de Tocqueville to emphasize that there is a need to spread liberal arts in the age of information.
Apart from North America, Tocqueville also made an observational tour of England, producing Memoir on Pauperism. In 1841 and 1846, he traveled to the French colony of Algeria. His first travel inspired his Travail sur l'Algérie, in which he criticized the French model of colonisation which emphasized assimilation to Western culture, advocating that the French government instead adopt a form of indirect rule, which avoided mixing different populations together. He went as far as openly advocating racial segregation as a form of consociationalism between European colonists and Arabs through the implementation of two different legislative systems for each ethnic group (a half century before implementation of the 1881 Indigenous code based on religion).

If conditioning has taken place, the neutral stimulus becomes the ____.
A. unconditioned response
B. conditioned response
C. unconditioned stimulus
D. conditioned stimulus
If conditioning has taken place, the neutral stimulus becomes the conditioned stimulus. Developing and strengthening a conditioned response happens through pairing a neutral stimulus with unconditioned stimulus that trigger a conditioned response.
Example of this is a dog that naturally salivated in response to food, but the dog also began to drool whenever they saw the man (which is previously neutral stimulus) who become associated with an unconditioned stimulus (the food) because he delivered the food where it naturally and automatically triggered a response (salivating).
