(09.01 HC) Prove that the two circles shown below are similar. (10 points)

lisov135 [29]

Answer:

Proved

Step-by-step explanation:

Given

Circle C

$R = 4$ --- radius

$(x,y) = (-3,1)$ --- center

Circle E

$r= 3$

$(x,y) = (4,9)$ --- center

Required

Prove their similarity

Translate circle C 8 units up;

The rule is:

$(x,y) \to (x,y+8)$

So, we have:

$(-3,1) \to (-3,1+8)$

$(-3,1) \to (-3,9)$

Translate circle C' 7 units right;

The rule is:

$(x,y) \to (x+7,y)$

So, we have:

$(x,y) \to (-3+7,9)$

$(x,y) \to (4,9)$

At this point, both circles now have the same center at (4,9)

The next step is to dilate circle E by 4/3

This will only affect radius and not the center of E

The rule is:

$r' = r * \frac{4}{3}$

$r' = 3 * \frac{4}{3}$

$r' = 4$

So, we have:

$R = r' = 4$ -- equal radii

$(x,y) \to (4,9)$ --- equal center

18+8x=-x-3(1+4x) what’s the answer

vredina [299]

Answer:

x=-21/19

Step-by-step explanation:

Given -> 18+8x=x-3(1+4x)

Distributive Property -> 18+8x=x-3-12x

Combine like terms on right side -> 18+8x=-11x-3

Subtract 8x from both sides -> 18=-19x-3

Add 3 to both sides -> 21=-19x

Divide both sides by -19 -> x=-21/19
