Answer:
6
∑ n^2
n=1
Step-by-step explanation:
There are 6 terms in the series, so we sum from 1 to 6
The terms are the integers squared
1^1, 2^2, 3^2 4^2, 5^2 6^2 or n^2
6
∑ n^2
n=1
Answer
In the following order. 3, 5, 2, and 4
If you are allowed to have one number left over then you do not use number 1.
Answer:
n = -2
Step-by-step explanation:
6n = 2n-8
4n = -8
n = -2
<em>Options:</em>
<em>Rotation of 180° about point B
</em>
<em>Rotation of 90° about point b
</em>
<em>Reflection over the x-axis
</em>
<em>Translation down 2 units</em>

Answer:
Rotation of 180° about point B
<em></em>
Step-by-step explanation:
Considering coordinates of point B
Assume the coordinates of the line at point B is (x,y)
i.e. 
First, we need to determine the slope at point B
Taking coordinates about the origin.
The slope of B is:

Where
--- origin

becomes


Taking the options one after the other:
Option A.
When rotated by 180°, the resulting coordinates of B would be

Taking the slope of B'
The slope of B is:

Where
--- origin

becomes



Notice that the slope of B and B' is the same;

<em>Hence:</em>
<em>Rotation of 180° about point B answers the question</em>
<em></em>
<em>There's no need to check for other options</em>
