Answer:
See below
Step-by-step explanation:
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,
1/2-1/4
(1/2x2)-1/4
2/4-1/4
2-1
1
1/4
Since you know the amount of what she earns you would use the number 15 and you dont know how long she worked you would put "x" next to the 15. so you would have 15x and then put a plus 5 to show her transportation fee. so you would have the equation of 15x+5:) and instead of x use h to show hours because h=hours
you feel me?
great!
Answer:
I would assume you're referring to this test? if so the answer is
a, d and e
x + y when x = 6 and y = 2
6 + 2 = 8
when x = 12 and y = 20
= 37
when m = 12 and n = 3
= 24
Six times x
6x
Six increased by x
6 + x
The sum of x and y
x + y
