5. A dart is thrown at a circular-disk-shaped dartboard of radius R. Assume that the dart lands in a random location on the dartboard (say because the thrower has no skill, and because complete misses are ignored in this analysis). What is the average distance between where the dart lands and the center of the dartboard

Distance=slopeslope is -2/4which equals-1/2the distance between these two points is -1/2

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
