For the dilation with a center (0,0) shown on the graph, your friend says the scale factor is 5/2. what is the correct scale factor? what mistake did your friend likely make?

From the given figure:

Coordinates of Pre-image triangle ABC are:

A (0, 5), B(-5, 0) and C(5, -5)

and

Coordinate of image triangle A'B'C' are;

A'(0, 2), B'(-2, 0) and C'(2, -2)

The rule of dilation with scale factor k and centered at origin is given by;

To find k;

A'(0, 2) = A'(0, 5k)

Comparing both sides we get;

5k = 2

Therefore, correct scale factor is

He did mistake in transformations i.e a huge mistake mathematically.

w'x is 0.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
