Let's take as example a linear function of the form:
y = kx.
Where,
k is the constant of proportionality.
Therefore, the proportionality constant is the point:
(x, kx)
Generically it is always the point:
(x, k * f (x))
Where, f (x) is a function proportional to x.
answer:
The constant of proportionality is always the point (x, k * f (x)), where k is the constant of proportionality.

Answer:
<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>
Step-by-step explanation:
Creative Landscaping has 60 yard of fencing with which to enclose a rectangular garden.
If the garden is X yards long, express the Gardens area as a function of length
Let x be the length of garden
So perimeter of rectangle = 60 yard
Perimeter = 2 * ( Length + width)
60 = 2 * ( x + width)
Width = 60/2 - x
Width= 30 - x
<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>
<span><span>Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.

Answer: I assume you mean surface area of a sphere.
The formula is 4πr²
If radius=3, then:
4 times 
times 3²
4 times times 9
= 113.142857
Rounded to 1 decimal place = 113.1
<u>NOTE: In place of π you can also use 3.14.</u>
