Answer:
The coordinates of vertices of A'B'C'D' are:
A'(1,-8), B'(0,-4), C'(2,-1) and D'(4,-3)
Step-by-step explanation:
When a point (h,k) is roated 180 degrees about the origin it becomes (-h,-k) which means that the new point after rotation is the negative of the previous.
Given vertices are:
A(-1,8), B(0,4), C(-2,1), and D(-4,3)
The new vertices will be:
The coordinates of vertices of A'B'C'D' are:
A'(1,-8), B'(0,-4), C'(2,-1) and D'(4,-3)

3. What are two ways that a vector can be represented?
Considering a vector in some vector space
we have
This is the component form. I don't like that way. It is probably used in high school, but
is preferable because the inner product on is defined to be
You can also write it using linear form such as
4.
For this question, I think you meant
vectors
Once
Considering that the dot product is
and the norm of is
and the norm of is
Thus,
