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
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.

Hello! Please help.
"Find the error & explain why it is wrong."
Answer: Step E
Step-by-step explanation:
The error is in the last step. In Step D, we see that we're supposed to subtract the second part from the first part. We also see we have the terms 2x-8 in the numerator on the right. Since we're subtracting, the expression should actually be -2x +8. 3 -2x +8 should be -2x +11 which is not the numerator in Step E so the last step is wrong.

1. Draw the points on the graph to represent the solutions.
2. What are the solutions? List them as ordered pairs.
(x,y)
10
3. Based on the graph, would you expect the discriminant
to be positive, negative, or equal to zero?
Answer:
1. The solutions marked on the attached graph
2.The solutions are (-2, 0) and (6, 0)
3. The discriminant would be positive
Step-by-step explanation:
The solution of the quadratic equation is the values of x at y = 0, which means the points of intersection of the graph and the x-axisThe discriminant is positive if the graph intersects the x-axis at two different pointsThe discriminant is zero if the graph intersects the x-axis at only one pointThe discriminant is negative if the graph does not intersect the x-axisBased on the given graph
1.
Look at the attached figure to see the solutions
2.
∵ The graph intersects the x-axis at points (-2, 0), (6, 0)
∴ The solutions are (-2, 0) and (6, 0)
3.
∵ The discriminant is positive if the graph intersects the x-axis
at 2 different points
∵ The given graph intersects the x-axis at points (-2, 0) and (6, 0)
→ They are different points
∴ The discriminant would be positive

Solve for x
Answer:
22.6
Step-by-step explanation:
The cos of any angle is its adjacent over its hypotenuse:
cos 37 = 17.3 / x
We can multiple both sides by x to get x * cos 37 = 17.3 and then we can divide both sides by cos 37 to get x by itself:
x = 17.3 / cos 37
So solving for x, x is equal to about 22.6

Answer: 54
Step-by-step explanation:
The value of m ∠C will be;
⇒ m ∠C = 54°
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In △ABC , m ∠A= 37° and m ∠B = 89° .
Now,
Since, In △ABC ,
⇒ m ∠A= 37° and m ∠B = 89°
We know that;
⇒ m ∠A + m ∠B + m ∠C = 180°
⇒ 37° + 89° + m ∠C = 180°
⇒ 126° + m ∠C = 180°
⇒ m ∠C = 180° - 126°
⇒ m ∠C = 54°
Thus, The value of m ∠C will be;
⇒ m ∠C = 54°

Suppose y varies directly with x and y=20 when x = 10. What is the value of y
when x = 30?
Answer:
y = 60
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 10, then
20 = 10k ( divide both sides by 10 )
2 = k
y = 2x ← equation of variation
When x = 30, then
y = 2 × 30 = 60
