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 is an expression of Charles's law k constant?
V/t=p
What are 1000 multiples of 7?
They are members of the set of numbers of the form 7*k where k is an integer which takes 1000 different values..
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).
How do you find the multplicate inverse of a rational number?
You take its reciprocal, that is you divide 1 by the number. A rational number can be written as a fraction with integer values in both the numerator and denominator, j/k. The multiplicative inverse of a number is what you have to multiply by to get a product of 1. Putting these ideas together, the multiplicative inverse is the reciprocal, or k/j: (j/k) * (k/j) = 1.
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.
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.
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.
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.
What is the difference between directly propotional and inversely proportional?
In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.
How are the absolute temperature and volume of a gas at constant pressure related?
The absolute temperature of a gas is directly proportional to its volume when pressure is constant, according to Charles's Law. This means that as temperature increases, the volume of the gas will also increase, and vice versa.
Is Y kx proportional or nonproportional?
The relationship Y = kx is proportional, where Y is directly proportional to x with a constant of proportionality k. This means that as x increases, Y also increases in a linear fashion. In a nonproportional relationship, the ratio of Y to x would not be constant, and the relationship could be more complex, such as quadratic or exponential.
How do you know if something is directly proportional?
Two quantities are directly proportional if they increase or decrease at a constant rate or ratio. This means that as one quantity increases, the other also increases, and vice versa. Mathematically, this relationship is expressed as y = kx, where y is directly proportional to x, and k is the constant of proportionality.
