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.

What is the simplified form of the quantity 12 z–squared minus 7z minus 12 over the quantity 3 z–squared plus 2z minus 8
ELEN [110]
12z^2 - 7z -12/ 3z^2 + 2z - 8

= (4z+3) (3z -4)/ (z+2)(3z -4)

= (4z + 3)  / (x+2)

Hope this helps

Well, you could easily type that into a calculator, but the answer would be 0.04347826, but when you say it as an answer you say the answer up to the hundredths place, which would be 0.043. =)
