Plz help me plz f(89) = -481.4 and f(126) = -677.5

10% of 1,900,000. show me how you got the answer

Given: pqrs is a parallelogram prove: pr and qs bisect each other at t

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.
