Answer:
PQ = 9.4
Step-by-step explanation:
to solve for PQ, use the distance formula
d = [tex]\sqrt{(x2-x1)^{2} + (y2-y1)^{2} }[/tex]
use two points
(x1,y1) = (4,3)
(x2,y2) = (-4,-2); and substitute into distance formula
d = PQ = [tex]\sqrt{(4+4)^{2} + (3+2)^{2} }[/tex] = [tex]\sqrt{8^{2} +5^{2} }[/tex] = [tex]\sqrt{64+25}[/tex] = [tex]\sqrt{89}[/tex] = 9.4

Which graph shows a dilation?
Answers
The second graph is the only option that has equal increment by a common factor and it is the only graph that shows dilation.
A dilation in graph is also known as transformation.
In the process of transformation or dilation in graph, all distances on the coordinate plane are increased by a common factor. It usually involves multiplying either all x-coordinates or all y-coordinates by a common factor greater than one.The increased x-coordinates is known as horizontal dilation and the increased y-coordinate is known as vertical dilation.
The second graph is the only option that has equal increment by a common factor. Thus, the second graph shows dilation.

A civics teacher asked her students to indicate whether they believed each of two headlines. One headline was false and the other was true, but the students did not know this. The probability that a student selected at random believed the true headline was 90\%90%90, percent and the probability that the student believed the false headline was 82\%82%82, percent. She found that 75\%75%75, percent of the students believed both headlines.
Answers
Answer:
The events are not mutually exclusive.
Step-by-step explanation:
To determine that in the sample, are the events "believed the false headline" and "believed the true headline" mutually exclusive.
For two events, let say E₁ and E₂ are said to be mutually exclusive if they cannot both occur simultaneously. In set-theoretical notation, we can say that the two sets E₁ and E₂ are disjoint. i.e. E₁ ∩ E₂ = ∅ and the probability of them occurring at the same time is zero. i.e. Pr( E₁ ∩ E₂ ) = 0
So, we can say;
Let P(true) = E₁
P(false) = E₂
Thus; statistically:
Pr( E₁ ∩ E₂ ) = Pr(E₁) + Pr(E₂) - P( E₁ ∪ E₂ )
So;
the probability of students that believed the true headline P(E₁) = 0.90
the probability of students that believed the false headline P(E₁) = 0.82
the probability of students that believed both P( E₁ ∪ E₂ ) = 0.75
∴
Pr( E₁ ∩ E₂ ) = 0.90 + 0.82 - 0.75
Pr( E₁ ∩ E₂ ) = 0.97
Thus, the events are not mutually exclusive.

Answers
Answer:
2[tex]x^{2}[/tex]+x-28
Step-by-step explanation:
To solve binomial multiplication problems you can use the FOIL method. FOIL means first, outside, inside, last, which tells you what order to multiply the terms.
Multiply the first terms,
(2x-7)(x+4)
2[tex]x^{2}[/tex]
Then the outside terms,
(2x−7)(x+4)
8x
Next the inside terms,
(2x−7)(x+4)
-7x
Finally the last terms,
(2x−7)(x+4)
-28
To find the answer put all of the products together and simplify
2[tex]x^{2}[/tex]+8x-7x-28
2[tex]x^{2}[/tex]+x-28

Answer:
x = 17 and y = 8
Step-by-step explanation:
Since (6x + 3) and (8x - 31) are alternate interior angles, they are congruent.
Therefore, you can set them equal to each other and solve for x.
8x - 31 = 6x + 3
Combine like terms
2x = 34
Divide both sides by two
x = 17
Since (5y + 35) and (6x + 3) are consecutive interior angles, they add up to 180. Plug in 17 for x.
(5y + 35) + (6(17) + 3) = 180
Add like terms
5y + 140 = 180
5y = 40
y = 8
A circle has radius 40 cm. Which of these is closest to its area, in square centimeters?
Answers
Answer:
251 cm2
Step-by-step explanation:
The area of the circle whose radius is 40 cm is 5026 cm².
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
Given that the radius of the circle is 40cm. Therefore, the area of the circle will be,
Area of the circle = π × Radius²
= π× (40cm)²
= 1600π cm²
= 5026.54 cm²≈ 5026 cm²
Hence, the area of the circle is 5026 cm².
