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,


Answer:
D. (-9)+9=0
Step-by-step explanation:
Additive inverse means that the sum of the original number and its Additive inverse must add upto 0. In this case, if we add -9 and 9 then we get 0. That's why D is the correct answer.
Answer:
The answer is 1.
Step-by-step explanation:
9^15 = 205891132094649
205891132094649(1/205891132094649
)
Cancel the common factor of "205891132094649
"
You are left with 1.
3 units/ 5 feet = 60 units/ 100 feet
3 units/ 5 feet = 18 units/ 30 feet
The dimensions of the scale drawing are 60 units by 18 units.
Hope this helps!
X^n ×X^n=X^10
X^n+n=X^10
X^2n=X^10
2n=10
n=10÷2
n=5
I hope you understand
