Every musical note has an associated frequency measured in Hertz (Hz), or vibrations per second. The following table shows the approximate frequencies of the notes in the octave from middle C up to the next C on the piano.

Step 1 Find a model that fits the data You should come up with an equation in the form y = Abx.

y=1.06b^x

Step 2 Use your model to find the frequency of the note two octaves above middle C (note 24).

1026

Step 3 Find the note with a frequency of 600. (How?)

note 15
