Ireally need with this question. i have been trying for hours and no one has me. a toy rocket is launched from a platform 29 feet above the ground at a speed of 79 feet per second. the height of the rocket in feet is given by the polynomial −16t^2 + 79t + 29, where t is the time in seconds. how high will the rocket be after 3 seconds?

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.
