Regular hexagon ABCDEF is inscribed in a circle with center H.
a. What is the image of segment BC after a 120-degree clockwise rotation about point H?
b. What is the image of segment BC after a reflection over line FC?
Answer both questions in the box below.
plz help me
Answers
I'm uploading a picture because it thought it had innapropriate words for some reason.
The transformation of a shape includes rotating and reflecting the shape;
The image of BC after [tex]120^o[/tex] is FAThe image of BC reflecting over FC is DC.(a) Image of BC after [tex]120^o[/tex] rotation
First, we calculate the angle of rotation, to make the hexagon lie onto itself
[tex]\alpha = \frac{\theta}{n}[/tex]
Where:
[tex]\theta = 360^o[/tex] --- angle at the center of the hexagon and the circle
[tex]n = 6[/tex] -- sides of hexagon
So, we have:
[tex]\alpha = \frac{360^o}{6}[/tex]
[tex]\alpha = 60^o[/tex]
This means that a [tex]60^o[/tex] rotation would make the hexagon lie onto itself.
We have that:
[tex]120^o = 60^o \times 2[/tex]
This means that the shape can be rotated [tex]60^o[/tex] twice to achieve the [tex]120^o[/tex] rotation.
The image of BC at the first [tex]60^o[/tex] rotation is AB
The image of BC at the next [tex]60^o[/tex] rotation is FA
Hence, the image of BC after [tex]120^o[/tex] is FA
(b) Image of BC after reflection over line FC
Line FC divides the hexagon into equal halves.
So, when reflected over line FC, each segment would be flipped on the opposite segment.
The opposite of segment BC is DC.
Hence, the image of BC reflecting over FC is DC.

What is the magnitude and direction angle of vector c?
|c| = 5, θ = 36.9°
|c| = 5, θ = 53.1°
|c| = 25, θ = 16.3°
|c| = 25, θ = 73.7°
Answers
Answer:
D
Step-by-step explanation:
The magnitude is 25 and the direction angle of vector c is 73.7°. Option D is correct.
Given, a=⟨2,10⟩, b=⟨-5,-14⟩, c=a-b
We need to find what is the magnitude and direction angle of vector c.
What is the magnitude and direction angle?Given a position vector v=⟨a,b⟩, the magnitude is found by |v|=√a²+b². The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application. For a position vector, the direction is found by tanθ=(ba)⇒θ=[tex]tan^{-1}[/tex](ba).
Now, vector c=⟨7,24⟩|c|=[tex]\sqrt{7^{2} +24^{2} }[/tex]=25angle =tan(θ)=(168)⇒θ=[tex]tan^{-1}[/tex](168)= 73.7°.
Hence, the magnitude is 25 and the direction angle of vector c is 73.7°.

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 20 child bikes and 6 adult bikes in a week.
No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answer:
I'm sorry I have no clue I'm not that smart but I would just like to say that I like your profile picture
Although I replied late, nobody gave the answer.
The answer you are looking for is C). But how do you know it's correct? Do some calculation.
Child bike: 4 hours to build + 4 hours to test = 8 hours total
Adult bike: 6 hours to build + 4 hours to test = 10 hours total
5*4 = 20 build hours for child bikes
5*4 = 20 test hours for child bikes
15*6 = 90 build hours for adult bikes
15*4 = 60 test hours for adult bikes
20 + 20 = 40 total hours for child bikes
90 + 60 = 150 total hours for adult bikes
20 + 60 = 80 total test hours
20 + 90 = 110 build hours
Since this amount is below the maximum, the bike order DOES meet the restrictions.
Our equations should be 4c + 6a ≤ 120 for the total building hours, and 4c + 4a ≤ 100 for the total testing hours.
In conclusion, the answer is C) Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100.

The cost of 12 widgets is $7.50. How much will it cost to buy 52 widgets?
Answers
Answer:
$32.50
Step-by-step explanation:
To answer this question, find the price per widget by dividing $7.50 by the number of widgets (12)
7.50 / 12 = 0.625
You may be tempted to round to 0.63 here, and maybe that is what your teacher wants, but typically you save rounding for the end of your calculations. So let's keep the price-per-widget at 0.625 and multiply it by the 52 widgets to find the total cost.
0.625 * 52 = 32.5 or $32.50
x = $7.50*52/12
x = $32.5

Part 2 Directions: Solve the matrix equation for "X" and "y" 5 - 2x 6 1 -8 + 2 -8 4. - 13 -13
Answers
Answer:
The value of x=9 and value of y= -7
Step-by-step explanation:
We need to solve the matrix equation for x and y
We are given:
[tex]\left[\begin{array}{cc}-2x&6\\1&-8\\\end{array}\right] +2\left[\begin{array}{cc}5&-1\\y&6\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]
First multiply 2 with terms inside the matrix
[tex]\left[\begin{array}{cc}-2x&6\\1&-8\\\end{array}\right] +\left[\begin{array}{cc}10&-2\\2y&12\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]
Now adding matrices on left side
[tex]\left[\begin{array}{cc}-2x+10&6-2\\1+2y&-8+12\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right]\\\left[\begin{array}{cc}-2x+10&4\\1+2y&4\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]
Now both sides are equal , so we can say that
[tex]-2x+10=-8 \ and \ 1+2y=-13[/tex]
Solving equations and finding values of x and y
Finding value of x
[tex]-2x+10=-8 \\-2x=-8-10\\-2x=-18\\x=\frac{-18}{-2}\\x=9[/tex]
Finding value of y
[tex]1+2y=-13\\2y=-13-1\\2y=-14\\y=\frac{-14}{2}\\y=-7[/tex]
So, value of x=9 and value of y= -7
