a is directly proportional to the square of m
So a = cm2 where c is the constant of proportionality.
a = 2.5 when m = 18.75
2.5 = c*18.752 c = 2.5/18.752
When m = 6,
a = (2.5/18.752) * 62
= 90/18.752 = 0.256

How do you find the constant of proportionality of y equals -2 when x equals 2?
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?.
How do you get the square meter area of land?
The land you are measuring is probably a rectangle, find the length of 2 sides (that are not directly across from each other) and then multiply them.
Can you help Find a formula for s in terms of t if s is proportional to the square root of t and s equals 118 when t equals 46 Enter an exact answer?
s = 11*t/sqrt(46).

What does coulombs law find?
Coulomb's law is used to calculate the electrostatic force between two charged particles. It states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Y is directly proportional to the square of x when x equals 4 y equals 25 Find an expression for the terms of x?

What is inverse square law of magnetism?
The inverse square law of magnetism states that the force between two magnets decreases as the square of the distance between them increases. This means that if you double the distance between two magnets, the force of attraction or repulsion will be reduced to one-fourth of its original strength.
How do you find the force of a charge?
To find the force of a charge, you can use Coulomb's law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The formula is F = k * q1 * q2 / r^2, where F is the force, k is the Coulomb constant, q1 and q2 are the charges, and r is the distance between the charges.

The temperature of an ideal gas is directly proportional to?
The temperature of an ideal gas is directly proportional to its average kinetic energy, which is related to the speed at which the gas particles are moving. As temperature increases, the kinetic energy and speed of gas particles also increase.

What 60000000 square meters in meters?
You cannot directly convert, square metres represents area where as metres simply represent distance. This is very basic maths. If the area was a square, you can find the area in square metres by multiplying the width in metres by the height.
