The height h in feet of a projectile launched vertically upward from the top of a 32 foot tall bridge is givem by h=38+16t-16t^2 where t is time in seconds. What is the maximum height an how long will it take the projectile to strike the ground?

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.
