The height of a cylinder is twice the radius of its base. A cylinder has a height of 2 x and a radius of x. What expression repr
mrs_skeptik [129]

<u>Given</u>:

Let x represents the radius of the cylinder.

Given that the height of the cylinder is twice the radius of its base.

The height of the cylinder is 2x.

We need to determine the volume of the cylinder.

<u>Volume of the cylinder:</u>

The volume of the cylinder can be determined using the formula,

V=\pi r^2h

Substituting r = x and h = 2x, we get;

V=\pi (x)^2(2x)

Simplifying, we get;

V=\pi x^2(2x)

V=2\pi x^3

Thus, the expression that represents the volume of the cylinder is 2πx³ cubic units.

Hence, Option b is the correct answer.

The graph of which function has an axis of symmetry at x = 3?
USPshnik [31]
You do this by converting to vertex form a(x - b)^2 + c   where the axis of symmetry  is x = b

the correct function to have a symmetry x = 3 will be the one which includes -6x
which is the last one 

x^2 - 6x - 1 =  (x - 3)^2 -9-1

the last option is the correct one

Are randomly choosing a person who is left-handed and randomly choosing a person who is right-handed mutually exclusive events?
Masteriza [31]

Answer: No .

Step-by-step explanation:

There are special cases where a person can use right and left hand equally well . I.e ambidextrous .

In statistical terms and probability theory, two events (or propositions) are mutually exclusive or disjoint if they cannot both occur at the same time .however in this case it may occur that the person is right and left handed at the same time .

Answer:

60=2(20)+2x

x=10

Step-by-step explanation:

First, let's write some equations. I wrote 60=2(20)+2x, where x is the length of the room. To solve, first multiply 2 times 20 for 40 (60=40+2x). Then, I subtracted 40 from both sides (20=2x). Finally, I divided on both sides by 2 (10=x).
