Is the airplane’s altitude a function of time? yes, because any input of time results in only one output of altitude. yes, because the airplane increases and decreases in altitude at the same rate. no, because each output of altitude has more than one input of time. no, because the altitude is constant between 60 minutes and 130 minutes.

What is the absolute value of the complex number -4-sqrt2i

Find the value of x. give reasons to justify your solutions! h ∈ ig

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.
