Use Direct and Inverse Variation · Exercise 29
Write an inverse variation equation to solve the following problems.
On a string instrument, the length of a string varies inversely as the frequency of its vibrations. An 11-inch string on a violin has a frequency of 400 cycles per second.
ⓐ Write the equation that relates the string length to its frequency.
ⓑ What is the frequency of a 10-inch string?
