Answer:
14.9
Step-by-step explanation:
Sin(58) × 15 = X
X = 14.89
round to the nearest tens
X = 14.9
Answer: 525 cycles per second.
Step-by-step explanation:
The equation for inverse variation between x and y is given by :-
(1)
Given : The length of a violin string varies inversely with the frequency of its vibrations.
A violin string 14 inches long vibrates at a frequency of 450 cycles per second.
Let x = length of a violin
y= frequency of its vibrations
To find: The frequency of a 12 inch violin string.
Put
in equation (1) , we get
Divide both sides by 12 , we get

Hence, the frequency of a 12 inch violin string = 525 cycles per second.
