Answer:

The path length is the same for the small and large semicircles.

Step-by-step explanation:

The distance around the large semicircle = 1/2 * π * diameter

= 1/2*8*π

= 4π m.

The distance around the 2 smaller semicircles

= 1/2 * 4 * π + 1/2 * 4 * π

= 2π + 2π

= 4π m.

B. (1, 20) and (6, 0)

C. (1, 0) and (6, 20)

D. no solution

Correct answer is C.

$y=x^2-3x+2 \\y=4x-4\\ \\4x-4=x^2-3x+2 \\x^2-7x+6=0 \\x^2-6x-x+6=0 \\x(x-6)-(x-6)=0 \\(x-6)(x-1)=0 \\x=6\,\text{ or }x=1 \\y=4\times 6-4=20 \,\text{ or }y=4\times 1-4=0 \\ \\(6,20)\,\text{ and }(1,0)$
