Let W be the subspace in R3 consisting of all solutions to the system x + 2y + 3z = 0 2x + 4y + 6z = 0 Find the projection of v = 2 4 1 1 1 3 5 onto W.

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.
