The length of the legs, PQ and PR are 4 units.

The lengths of the legs, P’Q’ and P’R’ are 1 unit.

Since the legs (and triangle) got smaller we know that the scale factor is between 0 and 1.

So.. 4 * x = 1

divide both sides by 4

x = 1/4**The scale factor is 1/4**

Eric’s statement is correct that the slopes of the perpendicular lines are opposites reciprocal with each other compared to Aviva’s. Aviva’s statement is correct but is not usually the case. An example is that when you are given these functions such as y = -2x + 3 and y = 1/2x + 4. The coefficients of the x variable are 2 and negative 1/2. The slopes must be in opposite signs so that the two functions will intersect at a common point and will form a ninety degree angle. This is the very basis of a perpendicular line because if both lines have the same slopes, then both lines are just parallel with each other, they cannot intersect.

Which of the following could be considered a negative side effect to instant information? A. the creation of the Associated Press B. the Panic of 1857 C. the Industrial Revolution D. the Transcontinental Railroad

**Answer: d. There is no slope.**

**Step-by-step explanation:**

We know that slope =

For the given table, since there is no change in x coordinate .

Thus the change in x coordinate is 0.

Therefore, slope=

which means the slope does not exist.

Hence, (d) is the right option. ** There is no slope.**

In the table, x represents minutes, and y represents the altitude of an airplane. Table x y 15 22,500 20 20,000 25 17,500 30 15,000 Which statement is correct about the slope of the linear function that the table represents? a.The slope is positive because as the minutes decrease, the altitude increases. b.The slope is positive because as the minutes increase, the altitude increases. c.The slope is negative because as the minutes decrease, the altitude decreases. d.The slope is negative because as the minutes increase, the altitude decreases.

well, the slope will be positive when the minutes (x) are increasing and the altitude (y) is also increasing

the slope will be negative when the minutes (x) are increasing and the altitude (y) is decreasing

we see that x increase

and y decreases

so the slope is negative because as minutes incrases, altitude decreases

D is answer

The emotion is an aspect of consciousness and can be characterized by a certain physical changes, brain activation, and tendencies toward action. Emotions can be positive but also negative and they are a natural and healthy art of our life. There are healthy ways to cope with emotions. It is important to realize that emotions are natural and learn acceptance of emotions. You should also adjust your expectations and don’t be disappointed.

14. **E 2.0 m/s^2**

Initially, a 20 N force is applied to the block, so it has an acceleration of 3.9 m/s^2. According to Newton’s law, the mass of the block is:

In the second situation, a force of 10 N is applied to the block. Since the mass is still the same, the acceleration now is:

So, approximately 2.0 m/s^2.

Since the sphere is suspended, it is in equilibrium, therefore the tension in the chain is equal to the weight of the sphere attached to it, therefore:

**17. C. A**

This arrangement generates the largest tension in the chain, because in all other arrangements the weight of the object is split between the two chains, while in this case all the weight is hold by one chain, therefore the tension in this case is larger.

**18. Straight path**

The gravity “holds” the planets keeping them in a circular orbit. If we remove gravity, the planets would continue in a straight path with constant speed, because now there are no more forces acting on it, so by inertia they will continue their uniform motion with constant speed.

**19. B. 1.6 × 104 N**

First we can find the deceleration of the car by using the SUVAT equation:

where v=0 m/s, u=2 m/s, and S=15 cm=0.15 m. Re-arranging, we have

And now we can calculate the average force exerted on the car, by using Newton’s second law:

(the negative sign means that the force’s direction is opposite to the motion of the car)

**20. A. magnetism**

Magnetism is part of the electromagnetic force, which is one of the fundamental forces which act also through empty space. All the other forces need some object in order to act.

**21. E. 45 N**

The magnitude of the force in link A is equal to the weight of the rod plus the weight of the lower block, therefore:

**22. C. on Earth at sea level**

The weight of the bowling ball is given by: , where m is the mass of the ball and g is the acceleration due to gravity. The value of g increases when moving from the Earth’s center to the Earth’s surface, then decreases when moving far from the surface, so the point where g is greatest is at sea level, where it is 9.81 m/s^2. On the surface of the Moon, g is much smaller (about 1/6 of the value on Earth).

**23. A. 0.5 m/s2**

The acceleration of the block is given by Newton’s second law:

**24. D. Both forces are equal in magnitude but opposite in direction.**

According to Newton’s third law: if an object A exerts a force on an object B, then object B exerts a force equal and opposite on object B. In this case, objects A and B are the bat and the baseball, therefore the two forces are equal in magnitude and opposite in direction.

**Answer: Joshua is correct**

**Explanation: **Animals, however well preserved and bred in conditions that are not in nature, that is, not in their natural habitat, animals still retain the animal instinct. Thus, young animals in the wild can be met daily, except for members of their species, and members of all other species, including predators, as well as humans. This means that in the natural environment, young animals can find themselves in a variety of dangers on a daily basis, but not only that. In this way young animals develop their ability to survive, escape from predators, manage, and develop their hunting skills, etc. All this is essential for socialization because according to all these developed skills and abilities their socialization depends. To deny any of the conditions prevailing in the wild means to deny the development of any skill or instinct, to deny proper socialization.

So, the number of ways is which 30 competitors from 50 can qualify is given by the formula of combinations, which is:

C (m,n) = m! / (n! * (m -n)! )

=> C (50,30) = 50! / (30! (50 – 30)! ) = (50!) / [30! (50 – 30)!] = 50! / [30! 20!] =

(x-h)^2 = +/- 4a(y-k) or (y-k)^2=+/- 4a(x-h), where

(h,k) are the coordinates of the vertex

a is the distance of the vertex to the focus

4a = length of lactus rectum or the focal width

If the equation contains (x-h)^2, then the parabola passes the x-axis twice. Similarly, (y-k)^2 passes the y-axis twice. If the sign is (-), it opens to the left(if y-axis) or downward (if x-axis). If the sign is (+), it opens to the right(if y-axis) or upward (if x-axis).

The equation of the parabola is -1/12 x^2 = y. Rearranging to the general form:

x^2 = -12y

Therefore,

-4a = -12

4a = 12

a = 3, and the parabola is facing downwards.

The vertex is (0,0) at the origin.

The focus is (0,-3). Since it is negative, the focus is situated downwards, hence -3.

The directrix is the mirror image of the focus. Hence, it is a line passing +3 on the y-axis. y=3

Focal width is 4a which is equal to 12 units.

**Answer:**

False

**Step-by-step explanation:**

Suposse that we are given a function f(x) and a constant value h.

1. Case:

If we take the function g(x)=f(x)+h, then the graph of the function g(x) will be the graph of the funcion f(x) moved up or down.

2.Case:

If we take the function g(x)=hf(x), then the graph of the function g(x) will be the graph of the function f(x) just taller or shorter.

3.Case:

If we take the function g(x)=f(x-h), then the graph of the function g(x) will be the graph of the fuction f(x) moved horizontally.

4. Case:

If we take the function g(x)=f(hx), then the graph of the function g(x) will be tha graph of the function f(x) wither or thiner.

For example:

If we take f(x)=sin(x) and h=2. Then, if we take g(x)=sin(2x) then f(0)=g(0)=0, which means that the graph of the functiction is not moved up or down. However, f(π/2)=sin(π/2)=1 and g(π/2)=sin(π)=0 which gives us a hint that the graph of the function became thiner.

**1.** The answer is** “C”.**

__ “Identical twins” __who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

**2.** The answer is** “A”.**

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in __ “consensus democracy” __in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

**3.** The answer is** “D. showing a learner how to correct common mistakes”.**

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

2. I do feel that most of the portrayal of family is accurate, on TV. Modern shows have steered away from the conventional “Mom, Dad, 2.5 kids plus dog” formula, which is accurate, because not all TV watchers are fortunate enough to have that kind of situation. See above answer for specific examples.

3. I think that a definite negative theme in today’s modern shows, revolve around views on alcohol and drugs. Obviously everyone is entitled to their own views, but more often than not, after a character drinks, or does something they shouldn’t, they panic about what their parents will do once they find out. This panic may lead them to increasingly dangerous situations. For example, in OTH, Nathan is drinking, and then goes out to drive his girlfriend’s car. When he crashes it into another car, he realizes the trouble he is in, and leaves the scene of the accident; thus potentially getting him in even more trouble. I realize that TV is in no way an accurate depiction of all life aspects, and it is “only TV”, but I think Nathan should have faced the consequences right away, because by running from the scene, he only put himself in danger of being caught, or arrested. Again, though, I’m reading too much into it.

The following equation of parabola is given:

p(x)= – 5 x^2 + 240 x – 2475

where p(x) = y

This is a standard form of the parabola. We need to

convert this into vertex form of equation. The equation must be in the form:

y – k = a (x – h)^2

Where h and k are the vertex of the parabola. Therefore,

y = – 5 x^2 + 240 x – 2475

y = -5 (x^2 – 48 x + 495)

Completing the square:

y = -5 (x^2 – 48 x + 495 + _) – (-5)* _

Where the value in the blank _ is = -b/2

Since b = -48 therefore,

y = -5 (x^2 – 48 x + 495 + 81) + 405

y – 405 = -5 (x^2 – 48 x + 576)

y – 405 = -5 (x – 24)^2

Therefore the vertex is at points (24, 405).
