Mabel was asked whether the following equation is an identity: (4x - 3)(x - 2)2 = 4x3 – 19x2 + 4x - 12 - She performed the following steps: (4x - 3)(x - 2)2 - - Step 1 (4x – 3)(x - 2)(x - 2) Step (4x - 3)(x2 - 2x - 2x + 4) II Step 3 = (4x – 3)(x2 - 4x + 4) Step 4 423 – 16x2 + 16x – 3.xº - 12x – 12 Step 5 4x3 – 19x2 + 4x – 12 For this reason. Mabel stated that the equation is a true identity, Fit

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.
