Question

A remote control car travels counter-clockwise around a circle with a 4 foot radius. The car begins at the 3 o'clock position on the circle (i.e., the point (4,0) in the zy plane and sweeps an angle with a measure of ? radians as it drives around the rack to its final position z, y as indicated in the diagram below. 4 ft (0,0) (4,0) (r, y) Estimate the values of the following expressions. Enter only values (or their opposites) from the following list: 0,0.1, 0.25, 0.4, 0.75, 1, 1.6, 3,4 cos(0)0.75 sin(8)04 * Preview Preview Preview Preview

Explanation / Answer

x = 3

y = -3

r = sqrt ( 3^2 + 3^2 )

r = sqrt 18

cos theta = 0.75

sin theta = -0.75
