Valerie drives 500 meters up a hill that makes an angle of 15° with the horizontal. To the nearest tenth of a meter, what horizontal distance has she covered?

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.

Answer! if you don’t mind, can you explain

Angle that produces maximum distance
