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?.

In inverse proportion x equals 2 and y equals 36 but what will y be when x equals 4?
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
Is the circumference of a circle a linear function of its radius?
Yes.You could also state that the circumference is directly proportional to the radius. The proportionality constant is (2 pi).
Find the constant variation for -3x plus 2y equals 0?
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.
F x varies directly with x and y equals -2 when x equals 8 Find the constant of variation k?
What is y? Fx varies with x, but y could be anything.
Y varies directly as the square of r If y equals 405 when are equals 9 find y when are equals 2?
y / r2 = a constant (k) so k = 405/81 ie 5. k = y/4 when r = 2, so y = 20.
What are the SI units of the proportionality constant G?
m^3/kg*s^2
What does x equals 2n mean?
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.
When f varies jointly as a and t and inversely as the square of b what is the answer when determining f when k equals 3 a equals 4 t equals 6 and b equals 2?
I am assuming that k is the constant of proportionality so that f = k*a*t/b2 = 3*4*6/22 = 18
What is the ratio of 2 corresponding linear measurements in a pair of similar figures?
The constant of proportionality or scale factor.
In inverse proportion x equals 2 and y equals 36 but what will y be when x equals 4?
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
What is a proportional relationship between 2 quantities?
A [directly] proportional relationship between two variables, X and Y implies thatY = cX where c is the constant of proportionality.
What is a 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.
What is the circumference of a circle when the radius doubles or trebles?
The circumference also doubles or trebles. The circumference is directly proportional to the radius, with the constant of proportionality = 2*pi.
Is the circumference of a circle a linear function of its radius?
Yes.You could also state that the circumference is directly proportional to the radius. The proportionality constant is (2 pi).
What is an equation that shows that one variable varies directly with the square of the other variable?
y=x^2 * k k=constant of proportionality OR y/x^2 = k
If y varies directly with x and y equals 6 and x equals -3 find y when x equals 4?
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
Find the constant variation for -3x plus 2y equals 0?
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.
