The position of some piano keys and the frequencies of the notes created by the keys are shown below. Use regression to find an exponential model for the frequency of piano notes shown. What is the frequency of the note created an octave (5 black notes) above the note labeled 20? 1 point How Did I Do? 5 Key 3 9 11 13 15 15 18 20 Frequency (in hertz) 29.14 32.70 36.71 41.20 46.25 51.91 58.27 65.41 73.42 82.41 The exponential model is in the form y = a(b) where a = Number and b= Number (round to 4 decimal places) The frequency of the notes created by the key 35 is Number Hertz. (Round the answer to 2 decimal places.)
