Answer:
H
Step-by-step explanation:
educated guess
Given two vectors

they are parallel if they are a multiple of each other:

You can easily test this by checking if

they are orthogonal if their dot product is null:

For example, in the first case, we have

So, they aren't parallel. Similarly, you have

So, they aren't orthogonal.
In the second case, we have

So, they aren't parallel, and

So, they are orthogonal.
Finally, we have

So, they are parallel (and thus can't be orthogonal)
To find the inverse of a function, you swap the x and y values. So instead of y=4x+8, it becomes x=4y+8. Now you re-solve for y, and that’s your answer:
x=4y+8
x-8=4y
1/4x-2=y
So h(x)=1/4x-2, or the first option
The answer is an Interval.
Hope this help.
Answer:
1. 1.28
2. 55
3. +
Step-by-step explanation:
1. 0.043 x 10 {3}
= 0.043 x (10 x 3)
= 0.043 x 30
= <u>1.28</u>
2. 5 + (9) (6) - 4
= 5 + 9 x 6 - 4
= 5 + 54 - 4
= 59 - 4
= <u>55</u>
3. Which of the these operations should be completed last when solvingan equation?
a. x
b. +
c. ()
d.÷
<u>b. +</u>
