We have been given that the inverse variation
shows the relationship between wavelength in meters, x, and frequency, y. We are asked to find the wavelength for radio waves with frequency
.
To find the required wavelength, we substitute
in our given equation and solve for x as:


We can see that both numerator and denominator has 3, so we can cancel it out.

Using quotient rule of exponents
, we will get:


Therefore, the wavelength for radio waves would be
meters and option B is the correct choice.
I think the answer is (-2-\sqrt(10))/(3)
i know that looks wierd...sorry...i hope this helps
The answer is 8.4 so you would need 9 rolls of ribbon
