Respuesta :

Answer: all I can give you is that for The first transformation: x is 2.5 and y is 2.5

Second: a is 1 b is 1

Answers to the other questions:

First question: 15

Third question: 28 units

Fourth question: 28 ft

Fifth question: 9.83 mi^2

Six: 3cm

7: 14pi feet

Best of luck!

         Rule for the first transformation : (x, y) → (2.5x, 2.5y)

         Rule for the second transformation : (x, y) → [(x - 4), (y + 1)]

Transformations of a figure:

  • If a figure is dilated by a scale factor 'k', rule defining the dilation will be,

         [tex]k=\frac{\text{Dimension of the image circle}}{\text{Dimension of the preimage circle}}[/tex]

  •  If a point (x, y) is shifted 'a' units left and 'b' units upwards,

          Rule defining the translation will be,

          (x, y) → (x - a, y + b)

From the picture attached,

Radius of image circle = 2.5 units

Radius of preimage circle = 1 unit

Scale factor 'k' = [tex]\frac{2.5}{1}[/tex]

                         = 2.5

Since, image circle (blue) is shifted to the left and upwards, rule for the translation will be,

(x, y) → [(x - a), (y + b)]

Following the rule, coordinates of the image circle will be,

(0, 0) → [(0 - a), (0 + b)]

         → (-a, b)  

Coordinates of the image circle from the picture → (-4, 1)

Therefore, -a = -4 ⇒ a = 4

                   b = 1

          First transformation: (x, y) → (2.5x, 2.5y)

          Second transformation : (x, y) → [(x - 4), (y + 1)]
