Students are working on problems where they convert distances measured in miles to kilometers. To estimate the number of kilometers, Tony takes the number of miles, doubles it, then subtracts 20% of the result. Zia first divides the number of miles by 5, then multiplies the result by 8. Do these two methods give the same results? Explain why or why not.

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.
