(over what interval) is the function positive

Simplify the expression 10/11(22z) + (a+5) -1

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.

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1
