Which of the following compositions produces the same image as R 0,-180?

Mathematics

Damm [24]3 years ago

The transformation RO - 180° means rotation of - 180°.

That is half-turn clockwise.

When you apply that rotation, the coordinates of a point (x,y) transforms into coordinates (-x,-y).

So, any coomposition that is equivalent to half-turn will produce the same image as RO - 180°.

These are some examples:

1) RO 90° and RO 90° (because 90° + 90° = 180° and that is equivalent to  -180°).

2) RO - 90° and RO - 90° (because - 90° - 90° = - 180°).

3) RO 90° and RO - 270° (becasue 90° - 270° = - 180°).

At the end there are infinite combinations equivalent to Ro - 180°, so, given that you did not include the set of choices, I have provided the explanations and examples which teachs you how to test any combination of rotations.

Naddika [18.5K]

Answer:

There is a 25/81 probability that Grace will make both of her next two shots.

Step-by-step explanation:

The probability of her making the first shot is 5/9.

The probability of her also making the shot after that is still 5/9, that does not change.

To find the probability of both of those events, multiply the fractions.

5/9 * 5/9

25/81.
