As shown in the figure below, Michael is standing 46 feet from the base of a leaning tree. The length of the tree is 68 feet. The angle of elevation from where Michael is standing to the top of the tree is 60 . Find the angle,0 , that the tree is leaning. Round your answer to the nearest tenth of a degree.

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.
