Answer:
The equation of parabola is standard form is 
Step-by-step explanation:
Given equation of parabola is,

In order to find the equation of parabola in standard form, eliminate x from left side of equation and use completing square method to find the equation.
First step is to add x on both side of equation.


Rewriting,

Now applying completing square method as follows.
Following are the steps for calculation of this method.
Find the last term of above equation by using below formula,

Now coefficient of y is 8.

Simplifying,


Second step is to add and subtract the last term.

Rewriting,

Since 
Using above formula,

Therefore, the equation of parabola in standard form is 
Answer:
V ≈ 254.5 in³
Step-by-step explanation:
The volume (V) of the cylindrical tube is calculated as
V = πr²h ( r is the radius and h the height ) , then
V = π × 3² × 9 = π × 9 × 9 = 81π ≈ 254.5 in³ ( to 1 dec. place )
Answer:
D) 2 less than the quotient of x divided by 4
Step-by-step explanation:
Since it's x/4 there has to be a quotient or division involved in the sentence, which eliminates A and B. Since there's a -2, C is eliminated since it doesn't include 2.
