Hallie applied a dilation given by the rule Do.8 (x, y) = (0.81, 0.8y) and centered at the origin (0,0) to a quadrilateral in a coordinate plane. The quadrilateral's image has vertices with coordinates of A'(-8, 12), B (4-8), C'(12.-4), and D' (16,8).​

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.
