Homework Help: Algebra 2

Posted by Don't wanna get caught! on Friday, May 6, 2011 at 2:44pm.

Since sound is generated by vibrations and travels in waves it can be modeled by trigonometric functions. When an object vibrates twice as fast, it produces a sound with a pitch one octave higher than before. Amplitude is associated with loudness. Suppose a sound can be modeled with the function g()= 15sin(200)

a) Write a function for a sound with the same pitch as the sound modeled by g but 3 times as loud.

b) Write a function for sound with the same volume as the sound modeled by g but one octave higher.

c) Write a function for a sound with the same volume as the sound modeled by g but 2 octaves higher


Thanks for the help (this is due by May 13, 2011)
