While in keyboarding class, a student spent 14 minutes typing a paper that contained 728 words. For this student, the total number of words typed, w, is proportional to the amount of time in minutes, t, that was spent typing. Which equation represents this proportional relationship?

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.

Rationalize the denominator- 12x/√x-10

Which geometric principle is used to justify the construction below?
