Use the properties of logarithms to expand log y -6z
Each logarithm should involve only one variable and should not have any exponents. Assume that all variables are positive.

If x + 10 = 70, what is x? a. 40 b. 50 c. 60 d. 70 e. 80

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.
