direct linear variation

quadratic variation

inverse variation

explain how you got your answer to question #4 using 1-2 complete sentences.

the length, g, of a cello string varies inversely as the frequency, f, of its vibrations (cycles per second). suppose it is known that an 18-inch-long cello string vibrates 300 cycles per second.

write an inverse variation equation for the situation above.

then, show how to find the frequency of a 15-inch-long cello string.
