1. Josiah Jumpstart took his Mustang in to Fern's Fixit shop. The total estimate for repair was $347 for 5 hours of labor. Fern ended up fixing the car in just 3 hours, which reduced
his charge to $237. Since Fern charges an hourly
rate for repairs, we can find the slope for this situation
a look at a table.

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.
