An't wait to Hit the Slopes! Andrew loves skiing-he just hates the ski lift. To make matters worse, the

ski lift has been acting up today. Andrew is using the GPS on his phone

to track the ski lift's progress as it travels up the mountain. It moves at a

steady rate of 400 feet per minute until it stops suddenly. Andrew calls his

friends to tell them that he is stuck. They talk on the phone for 10 minutes

until finally the ski lift begins moving again…what is the x and y?

Which number is irrational? a) 16 b) 18 c) 25 d) 36

Find the average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

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.
