Solve Applications with Rational Equations · Example 10
The frequency of a guitar string varies inversely with its length. A 26 in.-long string has a frequency of 440 vibrations per second.
ⓐ Write the equation of variation. ⓑ How many vibrations per second will there be if the string’s length is reduced to 20 inches by putting a finger on a fret?
