circle a has center of (6,7) and a radius of 4 and circle b has a center of (2,4) and a radius of 16. what steps will show that circle a is similar to circle b

the choices are:
translate circle a using the rule (x+4,y+3).
rotate circle a 45° about the center.
dilate circle a by a scale factor of 4.
reflect circle a about the origin.

Dilate Circle A by a scale factor of 4.

Step-by-step explanation:

Figure 1 shows Circles A (red) and B (green) before any transformations.

Figure 2 shows Circle A dilated about its centre by a factor of 4.

It is now apparent that every radius in A' has a corresponding radius in B, so the circles are similar.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

the answer

b. they are parallel and will never intersect.
