The frequency, f of a sound wave is inversely proportional to the wavelength, 1. Write an equation f = 420 when I = 0.5 * B f = k/l 20 = K/0.8 336 = k f = - 336 * l 4. The cost per person to rent a cmountain cabin is inversely proportional to the number of people who share the rest. If the cost is $36 per person when 5 people share, what is the cost per person when 8 people share?
