Answer:
14. D
15. A
16. A
Step-by-step explanation:
14. Point slope form formula: y-y₁=m(x-x₁).
When graphing you always want to think x/y for your slope.
X-axis increases by 2 and the Y-axis increases by 10, which would make the slope (m) 2/10 = 1/5.
If your slope is does not come out correct, then you can prove your point.
15. The given information is (-2,2): m=-1.
Given the Point slope formula: y-y₁=m(x-x₁), you can replace m to -1, y₁=2 and x=+2. (Two negatives would make a positive.)
Your answer: y-2=-(x+2)
16. Given: y=4x-7; (3,0)
Parallels lines: Same slope different y-intercepts.
A and D has the same slope and different y-interecepts, but your answer would be A because the equation that was given as a negative y-intercepts.
The answer is 32, depending on how you do the math will be different outcomes
Answer:
See below
Step-by-step explanation:
Recall
Using the chain rule
such that 
we can get a general formulation for
Considering the power rule
we have
therefore,
Now, once
we have
Hence, we showed
================================================
For the integration,
considering the previous part, we will use the identity
thus
and
Considering
and then 
we have
Therefore,
