Answer:
A. 110 Hz
Step-by-step explanation:
An octave above of a frequency is directly the double Hz than the original frequency, for example, if you are given the frequency 40hz, an octave above would be (40hz)x(2)= 80hz, so if you want to discover the two octaves below 440hz you just have to divide it by half, and then again by half, like this:
[tex](440 hz)(\frac{1}{2})(\frac{1}{2})[/tex]
And the answer would be:
110 hz.
