Answer:

I think there should be a picture for this, but since I don't see any, I will just explain visually.

On a number line, you would go 4 steps or bars to the left (since it is negative) and then since it is minus, minus, it would be the OPPOSITE of negative, which is positive. so you go from -4 to 6 steps to the right.

Step-by-step explanation:

Did you know that there is a easy way to know this?

If you see -(-, it looks like a plus (+), right?

Well, it is!! This is how I remember it, and it is the easiest and fun way to remember it. Remember, -(- is +.

So, the equation would be

-4 + 6.

To solve the answer, you can do 6 - 4. Since 6 is a positive and has a greater value, you would subtract 4 from it to get a positive number. 6 minus 4 is 2, so on the number line, you should end at positive 2.

Give the first five terms of the sequence <br> an=2n2+2

Eddi Din [679]

Answer:

The answer to your question is 3, 9, 19, 33, 51

Step-by-step explanation:

Sequence an = 2n² + 1

1st term a₁ = 2(1)² + 1 = 2(1) + 1 = 2 + 1 = 3

2nd term a₂ = 2(2)² + 1 = 2(2)² + 1 = 2(4) + 1 = 8 + 1 = 9

3rd term a₃ = 2(3)² + 1 = 2(3)² + 1 = 2(9) + 1 = 18 + 1 = 19

4rd term a₄ = 2(4)² + 1 = 2(4)² + 1 = 2(16) + 1 = 32 + 1 = 33

5th term a₅ = 2(5)² + 1 = 2(5)² + 1 = 2(25) + 1 = 50 + 1 = 51

A cylinder has a radius of 14 m and a height of 6 m.

oksano4ka [1.4K]

Option D: $1176 \pi \ {m}^{3}$ is the volume of the cylinder

Explanation:

Given that the cylinder has a radius of 14 m and a height of 6 m

We need to find the exact volume of the cylinder.

The formula to determine the volume of the cylinder is given by

$Volume=\pi r^{2} h$

Let us substitute $r=14$ and $h=6$ in the above formula, we have,

$Volume=\pi (14)^{2} (6)$

Squaring the terms, we get,

$Volume=\pi (196)(6)$

Multiplying we have,

$Volume=1176\pi \ m^3$

Thus, the volume of the cylinder is $1176 \pi \ {m}^{3}$

Therefore, Option D is the correct answer.

A class of 33

pogonyaev

Answer:

42.3% or 11/26

Step-by-step explanation:

IN order to calculate the percentage of people that voted for Candidate A you just need to add up the number of votes for that candidate and then multiply it by 100 and divided by the total votes.

There were 26 voters, since there were 7 that didn´t vote for anyone, so we have that 11 voted for Candidate A:

$\frac{11}{x} =\frac{26}{100}\\ x= \frac{11*100}{26}\\ x=42.30$

So the percentage of voters that voted for candidate A was 42.3 percent.
