A full circle = 360 degrees.

DOC + COB + DEB = full circle = 360

44 + 80 + DEB = 360

124 + DEB = 360

DEB = 360 - 124

DEB = 236 degrees

Circle 1 has a center (−4, 5) and a radius of 6 cm. Circle 2 has (2, −3) and a radius of 9 cm. What transformations can be appli
beks73 [17]

Answer:

The circles are similar because the transformation rule (+ 5 , - 6) can be applied to Circle 1 and then dilate it using a scale factor of ​3/4.

Step-by-step explanation:

All the circles are similar.

That is because you can transform one circle onto another by two similarity operations: translation and dilation (scale factor).

For these two circles you have to translate the center of circle 1 to the center of circle 2, which will make that the two circles are concentric (have the same center).

The two centers are (-6,2) and (-1,- 4). To move the center (-6, 2) to (-1,4) you have to shift it 5 units to the right and 6 units down:

- 6 + 5  = - 1

2 - 6 = - 4.

After this translation, you dilate the circle with smaller radius using a scale factor equal to the ratio of the bigger radius to the smaller radius: 8/6 = 4/3.

Enter the scale factor as a fraction in simplest form. 3/4

The circles are similar because the transformation rule (+5 , - 6) can be applied to Circle 1 and then dilate it using a scale factor of ​3/4.

Please please help me out......... :)
Vika [28.1K]

Answer:

B

Step-by-step explanation:

The red graph is the graph of y = f(x) translated horizontally by 3 units

Given f(x) then f(x + a) is a horizontal shift of a units

• If a > 0 then shift to the left of a units

• If a < 0 then shift to the right of a units

Here f(x) has been shifted 3 units to the right, thus

y = f(x - 3) → B
