A Johnny throws a football off the balcony to his buddy on the ground. The
position of the ball in the air can be modeled by the equation
16t2 + 176t + 192 , where t represents the time and y represents the
height above the ground.
b.) How high does the football go in the air?

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.
