Consider △DEF with vertices D(−6,4),E(0,8), and F(2,−2). Find the coordinates of the vertices of the final image of △DEF after the similarity transformation. Translation: (x, y)→(x+8,y+4)
Dilation: (x, y)→(12x,12y), centered at (0,0)

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.
