11. If 8,000 units are produced, what is the total amount of manufacturing overhead cost incurred to support this level of production? What is this total amount expressed on a per unit basis? (Round your "per unit" answer to 2 decimal places and other answers to the nearest whole dollar amount.)

Rotation of 90°, i.e., RO 90°, of a point P (a,b) transforms it into the point P' (b, -a).

So, RO 90° of point (0,5) will thransform it into the point (5,0), so that is the answer.

Rotation 180° will transform the point (0,5) into the point (0,- 5).

RO 270° will transform (0,5) into (-5,0).

RO - 90° is the same that RO 270°

RO - 180° is the same that RO 180°.

So, the only that applies is first one: RO 90°
