The volume of the cylinder is based on the formula: Volume = base * height where base is the circular shapebase area is equal to pi r^2. radius in this case is 3 inches and height is 6 inches. Hence the volume is pi * 3^2 *6 or equal to 54 pi. The answer to this problem is C. 54 pi in3.

Solve the system shown.

1. Rewrite the system:

 x+12y=68  (i)
 x=8y-12   (ii)

 2. Let's substitute the equation (ii) into the equation (i):

 x+12y=68
 (8y-12)+12y=68

 3. Then, you have:

 8y-12+12y=68

 4. When you clear "y", you have:

 20y-12=68
 20y=68+12
 20y=80
 y=80/20
 y=4

 5. You already have the value of "y". Now, you must substitute this value into the equation (ii):

 x=8y-12
 x=8(4)-12
 x=32-12
 x=20

 6. Therefore, the result is:

 x=20
 y=4

Identify whether the relations given in the options are functions or not.
stellarik [79]

Answer:

Graphs 1, 2, and 3 are not functions. Graph 4 is a function.

Step-by-step explanation:

Use the vertical line test.

Imagine a vertical line moving from left to right.

If in any position of the vertical line, it intersects more than one point on the graph, then it is not a function.

In graphs 1 and 2 it is clear that there are many vertical lines than would intersect the graph at more than one point.

In graphs 3, a vertical line would intersect the vertical parts of the graph at more than 1 point, so graph 3 is not a function.

The only function is graph 4.

6! = (4! x (6-4)!) =<br>​
Eduardwww [97]

Answer:

<h2>6! = 720</h2><h2>(4! × (6 - 4)!) = 48</h2>

Step-by-step explanation:

n! = 1 · 2 · 3 · 4 · ... · n

6! = 1 · 2 · 3 · 4 · 5 · 6 = 720

(4! × (6 - 4)!) = (1 · 2 · 3 · 4 × 2!) = 24 × 1 · 2 = 24 × 2 = 48
