Answer: 
Step-by-step explanation:
We know that:
: The number of vibrations per second of the nylon guitar string.
: Tension.
: The length of the string.
Since varies directly with the square root of the and inversely with , the equation has the following form:
Where "k" is the constant of variation.
Knowing that when 
and 
, 
, we can find the value of "k":
Finally, in order to find the tension when the length is 0.3 meters and the number of vibrations is 12, you need to substitute these values and the value of "k" into and solve for :
-27 can be rewritten as -3 * -3 * -3
So the 3rd root of -27 is -3.
(You can check on the calculator to make sure as well)
Answer: B
Option is B) y-3x=0 represents a proportional relationship between the x and y values
Explanation:
Case 1 = y+4=3x
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 4 .
Case 2: y-3x=0
From the above equation we can see that if we change the value of x, the value of y changes by proportionality.
Hence the correct option is B.
Case 3 = y+5x=6
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 6.
Case 4 = y+1/4×x=2
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 2.
