Which undefined term is used to define an angle?

2 answers:

4 0

Formed by two rays with a common endpoint. The endpoint is the vertex. And the two rays are the sides. Example name= PQR (Q is the vertex)

Answer:

Point

Step-by-step explanation:

Let's see the definition of angle.

An angle is formed by two rays starting from the same point and extending in two different direction.

The point is called the vertex.

Here the undefined term is "point"

when price of indomie noodles was lowered from #50 to #40 per unit, quantity demanded increases from 400 to 600 units per week.

Answer:

The price elasticity of demand is -10

Step-by-step explanation:

Given

$p_1,p_2 = 50,40$

$q_1,q_2 = 400,500$

Solving (a): The coefficient of price elasticity of demand (k)

This is calculated as:

$k = \frac{\triangle q}{\triangle p}$

So, we have:

$k = \frac{500 - 400}{40 - 50}$

$k = \frac{100}{-10}$

$k = -10$

Because |k| > 0, then we can conclude that the company made a wise decision.

Use always, sometimes or never to make a true statement:

viva [34]

Answer:

1. Intersecting lines are always coplanar

2. Two planes never intersect in exactly one point

3. Three points are always coplanar

4. A plane containing two points of a line always contains the entire line

5. Four points are sometimes coplanar

6. Two lines never meet in more than one point.

7. Two skew lines are never coplanar

8. Line TQ and Line QT are always the same line.

Step-by-step explanation:

Note: Coplanar means "In the same plane"

1. Each line exist in many planes. But different lines must share at least one plane for them to intersect. That is why intersecting lines are always coplanar.

2. Two planes never intersect at exactly one point because only lines intersect at a point. Planes can only intersect along a line.

3.Three points are always coplanar because in geometry, a group of points are coplanar because there is a geometric plane that they all lie on.

4. A plane containing two points of a line always contains the entire line. Yes

5. Four points are only sometimes coplanar because there is a probability that they may all not lie on the same plane

6. Two lines never meet in more than one point because lines are basically straight and cannot bend over to intersect at another point

7. Two skew lines are never coplanar because skews lines are lines that do not intersect and are never parallel.

8. Line TQ and Line QT are always the same line because a line is straight and extends from one point to the other. So, if a line is labelled TQ calling it QT means the same thing
