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.

Answer:
Step-by-step explanation:
Given definite integral:
<u>Integration by substitution</u>:
Substitute u for one of the functions to give a function that's easier to integrate.
Find the derivative of u and rewrite it so that dx is on its own:
Use the substitution to change the <u>limits</u> of the definite integral from x-values to u-values:
Therefore, the limits are <u>unchanged</u>.
Substitute everything into the original integral and solve:
