Any letter of the alphabet - or indeed other alphabets - can be used. The letters c and k are the more common symbols because they represent the phonetic start of "constant".
Variables are often represented by the initial letter of the variable: v for velocity, t for time, m for mass and so on, or by letters at either end of the alphabet: a, b, c or x, y, z. Clearly, it can be confusing to use any of these as the constant of proportionality. So, through convention, k was selected as the default symbol.

How do you find constant of proportionality?
You need to know the basic relationship between the variables: whether they are directly of inversely proportional to each other - or to a power of the other. Also, you need one scenario for which you know the values of both variables.So suppose you have 2 variables A and B and that A is directly proportional to the xth power of B where x is a known non-zero number. [If the relationship is inverse, then x will be negative.]Then A varies as B^x or A = k*B^xThe nature of the relationship gives you the value of x, and the given scenario gives you A and B. Therefore, in the equation A = k*B^x, the only unknown is k and so you can determine its value.

What are 1000 multiples of 7?

If y varies inversely as x and y 5 when x 2 find x when y is 4?
Since ( y ) varies inversely as ( x ), we can express this relationship as ( y = \frac{k}{x} ), where ( k ) is a constant. Given that ( y = 5 ) when ( x = 2 ), we can find ( k ) by substituting these values: ( 5 = \frac{k}{2} ), which gives ( k = 10 ). Now, to find ( x ) when ( y = 4 ), we set up the equation ( 4 = \frac{10}{x} ). Solving for ( x ) gives ( x = \frac{10}{4} = 2.5 ).
What is ideal gas constant r?
It is the value of the constant which appears in an equation relating the volume, temperature and pressure of an ideal gas. Its value is 8.314 4621 Joules/(Mol K).
If y equals kx then what is the relationship between x y and k?
Various options: y is directly proportional to k, with x as the constant of proportionality; y is directly proportional to x, with k as the constant of proportionality; x is inversely proportional to k, with y as the constant of proportionality; x is directly proportional to y, with 1/k as the constant of proportionality; k is directly proportional to y, with 1/x as the constant of proportionality; and k is inversely proportional to x, with y as the constant of proportionality.
Which set of values describes two quantities that are in a proportional relationship?
Two quantities are in a proportional relationship if they maintain a constant ratio or rate. For example, if you have the values (2, 4) and (3, 6), the ratio of the first quantity to the second is the same for both pairs: 2:4 simplifies to 1:2, and 3:6 also simplifies to 1:2. Thus, any pair of values that can be expressed as k times the other (where k is a constant) indicates a proportional relationship.
How do you work out a formula for a in terms of b when a is inversely proportional to b?
a = k/b when a is inversely proportional to b, where k is a constant.
When the product of two variables is constant the variables are proportional to each other?
Yes. They are inversely proportional. The proportion y ∝ 1/x, means xy=K, where K is the constant.
What. A proportional relationship exists between x and y. When x=8 the value of y is 14. A) Write an equation for y in terms of x.?
In a proportional relationship, y is directly proportional to x, meaning y = kx, where k is the constant of proportionality. To find k, we can use the given values: 14 = k(8). Solving for k, we get k = 14/8 = 1.75. Therefore, the equation for y in terms of x is y = 1.75x.
Which table shows a proportional relationship between x and y?
A table shows a proportional relationship between x and y if the ratio of y to x is constant for all pairs of values. This means that for each value of x, the corresponding value of y can be expressed as y = kx, where k is a constant. To identify such a table, check if the values of y divided by the corresponding values of x yield the same result throughout the table. If they do, then the relationship is proportional.
When two values change in opposite directions so that if one increases and the other decreases by the same amount they are said to be inversely proportional to each other?
When two values are inversely proportional, one value increases as the other decreases, keeping their product constant. In mathematical terms, this relationship can be expressed as y = k/x, where y and x are the two values and k is the constant of proportionality. Examples include the relation between speed and time to travel a certain distance, or pressure and volume of a gas at constant temperature.
What is inversely and directly proportional?
Two variables, X and Y are said to be in inversely proportional is X*Y - k where k is some non-zero constant. X and Y are said to be directly proportional if X = c*Y where c is some constant.
How do you know if a linear relationship is proportional or not?
A linear relationship is proportional if it passes through the origin (0,0) and can be expressed in the form (y = kx), where (k) is a constant. To determine if a linear relationship is proportional, check if the ratio of (y) to (x) remains constant for all values. If the relationship has a y-intercept other than zero (e.g., (y = mx + b) with (b \neq 0)), it is not proportional.
Which equation represents the statement r is inversely proportional to s and directly proportional to the cube of t?
r = k(t^3 / s) where k is a constant of proportionality.
How do you tell if a math table is inversely proportional or directly proportional?
Generally, if y increases as x increases, this is a hint that the quantity is directly proportional, and if y decreases as x increases, the relation might be inversely proportional. However, this is not always the case. x and y are directly proportional if y = kx, where k is a constant. x and y are inversely proportional if y = k/x, k is constant. This is the best way to tell whether the quantities are directly or inversely proportional.
Is y-2.5x a proportional relationship or no?
A proportional relationship exists when two variables are related by a constant ratio. In the expression y-2.5x, there is no constant multiplier connecting y and x, indicating a non-proportional relationship. If the relationship were proportional, the expression would be in the form y = kx, where k is a constant.
