Jack and Jill are selling pails that carry water. The cost of Jack’s pail is represented by the equation p=5/4w where p is the price of the pail in dollars and w is the volume of the pail, in gallons.
Jill’s pail prices can be modeled with the graph found on the right.
1. Suppose Jack graphed his equation. Identify the slope of his graph and explain what it means.
2. Identify the slope of Jill’s graph and explain what it means.
3. How do the slopes of the graphs compare? Explain.

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.
