Identify the rotation rule on a coordinate plane that verifies that triangle a(2,-1), b(4,1), c(3,3) and triangle a'(-2, 1), b'(-4,-1), c'(-3,-3) are congruent when rotated 180°. a) (x, y) → (-y, x) b) (x, y) → (-x, -y) c) (x, y) → (y, -x) d) the triangles are not congruent

Drag the tiles to the correct boxes to complete the pairs. not all tiles will be used. the heights of the girls in an advanced swimming course are 55, 60, 59, 52, 65, 66, 62, and 65 inches. match the measures of this data with their values.

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function. a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
