Answer:

Step-by-step explanation:

Rotations are easy when its multiples of 90 degrees; 90,180,270,360. Treat them like they’re a complex number like [x+yi]*i=[-y,xi] so rotating by 90 degrees and 180 is i squared [-1]! So [-3,2] rot90 is [-2,-3].

Reflection about the y=x line is change places. [x.y]=[y,x].

So [-2.-3] reflected about the y=x line is [-2.-3]=[-3.-2],

Compile a list of these transform is best practice technique in this area.

NoT YellInG ThIS IS JuSt TO AtTRaCT AtTeNTiOn 50 POiNtS PLeaSE ANswER I Am NoT WasTiNg PoInTS!!! Find the range of 1 1/4, 5/8, 3
Arada [10]

Answer:

<u>Range = 1 1/4</u>

Step-by-step explanation:

Range = Maximum - Minimum

Arranging the data in ascending order :

  • <u>1/2, 5/8, 3/4, 1 1/4, 1 1/2, 1 3/4</u>

<u />

Solving for range :

  • Range = 1 3/4 - 1/2
  • Range = 1 3/4 - 2/4
  • Range = 7/4 - 2/4
  • Range = 5/4
  • <u>Range = 1 1/4</u>

The vertices of shape K are at (4,7), (7, 7), (7,4) and (5, 5).
son4ous [18]

Answer:

To find the scale factor of the enlargement, compare the distance between a pair of corresponding points from both shapes.

<u>Shape K</u>

A = (4, 7)

B = (7, 7)

C = (7, 4)

D = (5, 5)

Horizontal distance between A (4, 7) and B (7, 7) = 3 units

<u>Shape L</u>

A' = (0, 11)

B' = (9, 11)

C' = (9, 2)

D' = (3, 5)

Horizontal distance between A' (0, 11) and B' (9, 11) = 9 units

9 ÷ 3 = 3

Therefore, Shape L is an enlargement of Shape K by scale factor 3.

To find the center of dilation (enlargement), draw two lines through 2 corresponding points (e.g. A and A',  B and B') - the point of intersection of these lines is the center of dilation.

Therefore, the center of enlargement is (6, 5)  (refer to the second attached image).
