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.
Answer:
6.44 square meters
Step-by-step explanation:
To solve for area of a rectangle, multiply the length by the width.

Answer:
b
Step-by-step explanation:
The answer would be 49 + 42b if you multiply 7*7 and 7*6b
