The equation of a circle centered at the origin with a radius of unit length is x2 + y2 = 1. This equation changes if the center of the circle is not
located at the origin or the radius is not of unit length. You will use the GeoGebra geometry tool to examine how the equation of a circle changes
as you move the center and change the radius. Go to equation of a circle C, and complete each step below. If you need help, follow these
instructions for using GeoGebra.
Question 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.
