y=kx and y= are two equations of constant of proportionality
Step-by-step explanation:
There are two equations for the constant of proportionality. That is
(i) Direct proportion
(ii) Inverse proportion
In direct proportion y=kx, Now
if x increases, then y also increases and if x decreases, then y also decreases. So, k is a constant proportionality.
In Inverse proportion y=, Now
if x increases then y decreases and if x decreases, then y increases and k is a constant proportionality.
In direct proportion, we put y=1 and x=2, So k=.
So, the equations y=kx and y= are two equations of constant of proportionality.
Answer:
on #1 x=2 and y=2
Step-by-step explanation:
a squared + b squared = c squared
2 squared + 2 squared = 4 squared
4 + 4 = 8
Answer:
A. 346.19 square feet.
Step-by-step explanation:
We have been given that a contractor has been hired to install flooring for a bandstand in the shape of a circle that is 21 feet across.
To find the square feet of flooring required, we will find area of circle.
Since the length across the circle is 21 feet, so radius of circle will be half of 21 feet.
Therefore, 346.19 square feet of flooring will be required.
