Find R(x)=f(x)g(x) where f(x)=x2−x−30/10x+100 and g(x)=−x2−5x+66/11x+110.

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52

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.
