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;

(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.

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.

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:

Based 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

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

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

Step-by-step explanation:

To find the total cost for each fruit you would multiply the number of fruit by the cost.

bananas=3*4.24=$12.72

grapes=4*2.37=$9.48

oranges=3*1.95=$5.85

apples=2*2.68=$5.36

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°
