Please need help with this problem

Mathematics
1 answer:
Crank3 years ago
7 0

Step-by-step explanation:

we see clearly that the side (leg) lengths changed from 3 units to 1 unit.

so, the scale factor is 1/3.

answer D is correct.

I assume the center of the dilation is the origin (0, 0).

so, C' becomes (-1, 0), A' becomes (-2, 0), B becomes (-2, 1).

it was then reflected across the y-axis (flipped over from the left side of the y-axis to the right side).

C'' becomes (1, 0), A'' (2, 0), B'' (2, 1).

and then it was translated (shifted) by (+1, -2), so that

C''' = D = (2, -2), A''' = F = (3, -2), B''' = E = (3, -1)

A circle has a radius of 12 inches. Find the length of the arc intercepted by a central angle of 120 degrees to the nearest tent
OlgaM077 [116]

Answer:

25.12 inches

Step-by-step explanation:

We have given the radius of the circle =12 inches

The central angle intercepted by the arc =120°

We have to find the length of the arc

So length of the arc is given by 2\pi \times r\times \frac{central\ angle}{360}

=\frac{2\times \pi \times 12\times 120}{360}=25.12inches

So the length of the arc will be 25.12 inch
