Question

Use rotation mapping to locate C′ after a −90 -degree (clockwise) rotation about the origin. (1 point) C′ (,)

Answer 1

To perform a \(-90\)-degree clockwise rotation about the origin, you can use the following rotation mapping formula for a given point \((x, y)\):

\[
(x, y) \rightarrow (y, -x)
\]

Let's denote the original coordinates of point \(C\) as \((x, y)\). After applying the rotation formula, the new coordinates \(C'\) will be:

\[
C' = (y, -x)
\]

If you provide the coordinates of point \(C\), I can calculate the exact coordinates for \(C'\).
