PLZ HELP DUE TOMORROW Question 3 The length (in inches), d, of a violin string varies inversely as the frequency (in cycles per second), f, of its
vibrations. Suppose it is known that a 16 inch long violin string vibrates 320 cycles per second.

Part A: Write an inverse variation equation modeling this information. Show your work by showing the
steps needed to create the equation.

Part B: Use your inverse variation equation from Part A to determine the frequency of an 8 inch long violin
string

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
