Help I have no idea how to solve this A coin is tossed upward from a balcony 228ft high with an initial velocity of 32 ft/sec. During what interval of time will the coin be at a height of at least 100ft? (h = -16t^2 + v0t (the zero is below v) + h0 (the zero is below h)

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.
