The frequency corresponding to the lower cut-off point is
The speed of sound at a temperature of
is approximately
Therefore we can use the relationship between speed of a wave, frequency and wavelength to calculate the corresponding wavelength:
So, the corresponding wavelength is 22.87 m.

Answer:
18feet
Explanation:
We need to find the distance,c between the vertex and the focus.
For a vertical parabola:
#If we place our parabola at the center, the expression changes to:
The points of the parabola are given as (12,2), substitute in our equation to find c:
Hence, the receiver should be placed at 18ft
