What transformation occurred between the set of points below?
A(-8,7) ► A'(-7-8)
B(-4.7) →B'(-7,-4)
C(-6,2)((-2,-6)
A
A reflection over the x-axis
B
Reflection over the y-axis
С
90° clockwise rotation
D 90° counterclockwise rotation

Answers

Answer 1

Given:

A(-8,7) → A'(-7-8)

B(-4,7) → B'(-7,-4)

C(-6,2) → C'(-2,-6)

To find:

The transformation occurred between the set of points above.

Solution:

From the given set of points it is clear that the rule of transformation is

(x,y) → (-y,x)            ...(i)

Because in the given set of points we interchange the x and y coordinates, then we are applying negative sign in the x-coordinate.

If a figure reflection over the x-axis, then

(x,y) → (x,-y)

If a figure reflection over the y-axis, then

(x,y) → (-x,y)

If a figure rotated 90° clockwise, then

(x,y) → (y,-x)

If a figure rotated 90° counterclockwise, then

(x,y) → (-y,x)

Only this rule of transformation is same as (i). So, the figure is rotated 90° counterclockwise.

Therefore, the correct option is D.

Brandon has an action figure collection. He keeps 178 of the action figures on his wall, which is 89% of his entire collection. What is the total number of action figures in Brandon's collection?

Answers

Answer:

200 total action figures

Step-by-step explanation:

178 * 100 / 89 = 200

Answer: 200


Steps:

x(.89)=178

Divide both sides by .89 to isolate x

x=200

Check:


If you multiply 200 by .89 to find 89% of 200 you will get 178.

Trapezoid WXYZ is shown on the coordinate grid. Trapezoid WXYZ is dilated with the origin as the center of dilation using the rule (x, y)→(4x, 4y) to create trapezoid W'X'Y'Z'.

Which statement is true?


Trapezoid W'X'Y'Z' is smaller than trapezoid WXYZ because the scale factor is less than 1.

Trapezoid W'X'Y'Z' is smaller than trapezoid WXYZ because the scale factor is greater than 1.

Trapezoid W'X'Y'Z' is larger than trapezoid WXYZ because the scale factor is less than 1.

Trapezoid W'X'Y'Z' is larger than trapezoid WXYZ because the scale factor is greater than 1.

Answers

Trapezoid W'X'Y'Z' is larger than trapezoid WXYZ because the scale factor is greater than 1.

Transformation

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the increase or decrease in the size of a figure by a factor k. If k > 1, it is an increment whereas if k < 1, it is a decrease.

Given the rule:

(x, y)→(4x, 4y)

k = 4 > 1, hence this is an increase.

Trapezoid W'X'Y'Z' is larger than trapezoid WXYZ because the scale factor is greater than 1.
