Mathematics

<h2>Answer:</h2>

This is easy. All you need to do is set up a <u><em>proportional relationship</em></u>.

A proportional relationship uses variables to show similarities, in this case, in triangles.

\frac{2}{3} = \frac{x}{6.3}\\\\3x = 12.6\\\\x = 4.2

<u><em>x</em></u> represents the missing side.

Identify the variation as direct, inverse, joint or combined. A = πr^2
Reika [66]

Answer:

1. y = 7x. This is an example of direct variation as the value of y also increases if the value of x is increased.

2. xy = 24. This is an example of inverse because the value of y is decreased when x is increased. 

3. F = 4/R. This is inverse variation for the same reason as number 2.

4. m/n = 4. Direct variation. For the same reason as number 1.

5. i = 2pr. Joint variation. The value of i is dependent on the values of two other variables.

6. R = cl/r². Joint variation.

7. A = pir². Direct variation. I believe pi here is for π, leaving only A being dependent only to value of r. 

8. V= pir²h. Joint variation.
