Determine the image of the point (-3, 4) under a rotation of 90° about the origin.
(-4, -3)
(4, 3)
(4, -3)
(4, 3)

(- 4, - 3 )

Step-by-step explanation:

Under a rotation about the origin of 90°

a point (x, y ) → (- y, x ), thus

(- 3, 4 ) → (- 4, - 3 )

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
