Trapezoid k prime is the image of trapezoid k after a series of transformations.

on a coordinate plane, trapezoid k has points (negative 4, 0), (negative 4, 4), (4, 4), (2, 0). trapezoid k prime has points (negative 3, negative 1), (6, negative 1), (6, negative 7), (negative 6, negative 7).

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.
