Answer:
B, A, C
Step-by-step explanation:
I think that you have wrong u-substitution ( partial integration ):
u=x, dv=cos 5x dx
du=dx, v=1/5 * sin 5x
Integral becomes:
Is it OK now?
Answer:
<h2><em><u>
First box and last box.</u></em></h2>
Step-by-step explanation:
<h2><em><u>
It is the first box.</u></em></h2>
Distribute 7 to the first number
7 * -3/4 = -21/4
-21/4 = 5 -1/4
Distribute 7 to the second number
7 * -3
= -21
Put the numbers together
<h2><em><u>
5 -1/4x -21 is the answer.</u></em></h2>
<h2><em><u>
It is also the last box.</u></em></h2>
They separated the parenthesis.
So it is still 7 * -3/4
and
7*-3.

First, we have two points and we need to use these points to find the slope. To do this, let's label one point x1 and y1, the other point x2 and y2 then,
Slope = (y2 - y1) / (x2 - x1)
(2, 3) - 2 is x1 and 3 is y1
(-1, -12) -1 is x2 and -12 is y2
Slope = (-12 - 3) / ( -1 - 2) = -15 / -3 = 5
Now the equation of our line is: y = 5x + b
Let's plug one of our points into this equation to solve for b.
3 = 5(2) + b
3 = 10 + b
Subtract 10 from both sides.
-7 = b
The equation of our line is: y = 5x - 7
-0.1 - (x) = 0.3
-0.1 - (-0.4) = 0.3
-0.1 + 0.4 = 0.3
0.3 = 0.3 (true)
-0.4 is your answer
hope this helps
