△JKL has vertices J(−3,5), K(−1,0) and L(8,−4). Which of the following represents the translation of △JKL along vector <−4, 7> and its reflection across the x-axis?
Answers:
J (−3, 5) → J ′(1, −2) → J ″(−1, −2);
K (−1, 0) → K ′(3, −7)→ K ″(−3, −7);
L (8, −4)→ L ′(12, −11)→ L ″(−12, −11)
J (−3, 5) → J ′(1, −2) → J ″(1, 2);
K (−1, 0) → K ′(3, −7)→ K ″(3, 7);
L (8, −4)→ L ′(12, −11)→ L ″(12, 11)
J (−3, 5) → J ′(−7, 12) → J ″(7, 12);
K (−1, 0) → K ′(−5, 7)→ K ″(5, 7);
L (8, −4)→ L ′(4, 3)→ L ″(−4, 3)
J (−3, 5) → J ′(−7, 12) → J ″(−7, −12);
K (−1, 0) → K ′(−5, 7)→ K ″(−5, −7);
L (8, −4)→ L ′(4, 3)→ L ″(4, −3)
Answer:
J (−3, 5) → J ′(−7, 12) → J ″(−7, −12);
K (−1, 0) → K ′(−5, 7)→ K ″(−5, −7);
L (8, −4)→ L ′(4, 3)→ L ″(4, −3)
Step-by-step explantion
Use the translation vector <−4, 7> to determine the rule for translation of the coordinates: (x,y)→(x+(−4),y+7).
Apply the rule to translate vertices J(−3,5), K(−1,0) and L(8,−4).
J(−3,5)→(−3+(−4),5+7)→J'(−7,12).
K(−1,0)→(−1+(−4),0+7)→K'(−5,7).
L(8,−4)→(8+(−4),−4+7)→L'(4,3).
To apply the reflection across x-axis use the rule for reflection: (x,y)→(x,−y).
Apply the reflection rule to the vertices of △J'K'L'.
J'(−7, 12)→J''(−7,−12).
K'(−5,7)→K''(−5,−7).
L'(4,3)→L''(4,−3).
Therefore,
J(−3,5)→J'(−7,12)→J''(−7,−12)K(−1,0)→K'(−5,7)→K''(−5,−7)
L(8,−4)→L'(4, 3)→L''(4,−3)
represents the translation of △JKL along vector <−4, 7> and its reflection across the x-axis.

Answer:
[tex]y=-5(x+2)-1[/tex]
[tex]y=-5(x+3)+4[/tex]
Step-by-step explanation:
Two points on the line are (-3, 4) and (-2, -1)
Therefore:
[tex]\textsf{let}\:(x_1,y_1)=(-3,4)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(-2,-1)[/tex]
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-4}{-2-(-3)}=-5[/tex]
Point-slope form of linear equation: [tex]y-y_1=m(x-x_1)[/tex]
Substituting point (-3, 4) in the point-slope equation:
[tex]\implies y-4=-5(x-(-3))[/tex]
[tex]\implies y=-5(x+3)+4[/tex]
Substituting point (-2, -1) in the point-slope equation:
[tex]\implies y-(-1)=-5(x-(-2))[/tex]
[tex]\implies y=-5(x+2)-1[/tex]

You are in a basketball 3-point contest. You have 1 regular ball, and 1 money ball left to shoot. If you make
both shots, you will get a total of 10 points. If you make just the money ball, you will get 3 points. Under
any other outcome, you will receive 0 points.
You approximate that the probability of you making the regular shot is 60% and the probability of you
making the money ball is 70%. You assume that each shot is independent.
What is the expected number of points you will score?
Answer:
10, if you make both shots;
3, if you make just the money ball
7, if you make just the regular ball

How many ways can a cook arrange 8 of 12 spice jars on a spice rack? 495 11,880 19,958,400 479,001,600
The number of ways that a cook can arrange 8 of 12 spice jars on a spice rack is; 495 ways.
How to solve probability Combinations?We want to find the number of ways that a cook can arrange 8 of 12 spice jars on a spice rack.
This is a Combination Problem which follows the formula;
nCr = n!/(r!(n - r)!
12C8 = 12!/(8!(12 - 8)!
Solving this gives;
12C8 = 495 ways
Thus, the number of ways that a cook can arrange 8 of 12 spice jars on a spice rack is 495 ways.

On Monday,221 students went on a trip to the zoo.all 4 buses were filled and 5 students had to travel in cars how many students were in each bus
Answer:
54
Step-by-step explanation:
If 5 students went in cars then 216 students were in the buses (221-5=216)
There were four buses so divide 216 by 5 which is 54.
So there were 54 students in each bus
Answer:
54
Step-by-step explanation:
If you have 221 students going to the zoo and 5 that went to the zoo in cars you only need to account for the 216 travelling by bus. So you subtract 5 from 221 and divide what you have left over (216) by 4 for the 4 buses you're using.
216/4= 54

Complete your work, including any drawings, on a separate piece of paper to solve the problem. Upload a copy of your solution here.
Please answer asap!! 40 Points!!!
The measure of angle BOC is 28.65°.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
The area of a triangle is,
Area = 1/2 × base × height
We have radius of the circle is 12 inches since OA = 12 which is the radius.
So, OB = 12 inches.
Height of the triangle AOB to the base OA = 12 sin (30°) = 12/2 = 6 inches
Area of ΔAOB = 1/2 × 12 × 6 = 36 inches²
Area of sector = (x/360°) πr², where r is the radius and x is the central angle formed.
Here x is ∠BOC.
Since area of sector = area of triangle,
(x/360°) π(12)² = 36
x π = 90°
x = 28.65°
Hence the required measure is 28.65°.

Answer:
p = [tex]-\frac{15}{2}[/tex], p = [tex]\frac{17}{2}[/tex]
Step-by-step explanation:
1. Subtract 15 from both sides:
- |2p -1| = -16
2. Divide both sides by -1:
[tex]\frac{-|2p - 1|}{-1} = \frac{-16}{-1}[/tex]
|2p - 1| = 16
3. Apply the absolute value rule (If |u| = a, a > 0, then u = a, or u = -a)
2p - 1 = 16 or 2p - 1 = -16
4. Solve for the positive and negative intervals:
2p - 1+1 = 16+1
2p = 17
[tex]\frac{2p}{2} = \frac{17}{2}[/tex]
p = [tex]\frac{17}{2}[/tex]
2p - 1+1 = -16+1
2p = -15
[tex]\frac{2p}{2} = \frac{-15}{2}[/tex]
p = [tex]\frac{-15}{2}[/tex]
