The Answers community requires more information for this question. Please edit your question to include more context. The answer will depend on the nature of proportionality between the two variables: is y directly proportional to x, or some power of x, is it inversely proportional?.
Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18
Yes.You could also state that the circumference is directly proportional to the radius. The proportionality constant is (2 pi).
2y - 3x = 0Put into Slope-Intercept form:2y = 3xDivide by 2:y = 3/2 * x = 1.5x3/2, or 1.5 is the constant of variation.
What is y? Fx varies with x, but y could be anything.
y / r2 = a constant (k) so k = 405/81 ie 5. k = y/4 when r = 2, so y = 20.
m^3/kg*s^2
It means that the variable x is twice as much as variable n. x is in direct proportion to n (or x varies directly as n) with the constant of proportionality = 2.
I am assuming that k is the constant of proportionality so that f = k*a*t/b2 = 3*4*6/22 = 18
The constant of proportionality or scale factor.

A [directly] proportional relationship between two variables, X and Y implies thatY = cX where c is the constant of proportionality.
Let's begin by assuming you have a direct ratio. 2 apples cost 45 cents. The constant of proportionality will be the apples per cent, or 2/45. Now, let's say you have an indirect proportionality. When x=6, y=10. Also, when x=5, y=12. Here, the C.O.P. is the total product of the numbers, so 6*10=60 and 5*12=60, which is no coincidence. The COP would be 60.
The circumference also doubles or trebles. The circumference is directly proportional to the radius, with the constant of proportionality = 2*pi.
Yes.You could also state that the circumference is directly proportional to the radius. The proportionality constant is (2 pi).
y=x^2 * k k=constant of proportionality OR y/x^2 = k
y/x is a constant; so first of you can solve for this constant. y/x=6/-3, or y/x=-2 y/4=-2 y=-8
