integration of sin3xsinx
Answers
Recall that
cos(x + y) = cos(x) cos(y) - sin(x) sin(y)
cos(x - y) = cos(x) cos(y) + sin(x) sin(y)
If you subtract the first equation from the second one, you end up with
cos(x - y) - cos(x + y) = 2 sin(x) sin(y)
so that
sin(3x) sin(x) = 1/2 (cos(3x - x) - cos(3x + x)) = 1/2 (cos(2x) - cos(4x))
Then in the integral,
[tex]\displaystyle \int \sin(3x)\sin(x)\,\mathrm dx = \frac12 \int(\cos(2x)-\cos(4x))\,\mathrm dx \\\\ = \frac12 \left(\frac12 \sin(2x) - \frac14 \sin(4x)\right) + C \\\\ = \boxed{\frac14 \sin(2x) - \frac18 \sin(4x) + C}[/tex]

A triangle with vertices at point A(-2,1), B(1,5), and C(2,3) calculate the coordinates of the mid point of AB
Answers
=======================================================
Explanation:
Add up the x coordinates of A and B
-2+1 = -1
Then cut that result in half
-1/2 = -0.5
This is the x coordinate of the midpoint.
Repeat these steps for the y coordinates: (1+5)/2 = 6/2 = 3
The midpoint of segment AB is located at (-0.5, 3)
How do you factor by grouping if the question is 2p^3+5p^2+6p+15?
Answers
Answer:
(2p + 5)(p² + 3)
Step-by-step explanation:
2p³ + 5p² + 6p + 15
take out factor p²
p² × (2p + 5) + 6p + 15
p² × (2p + 5) + 3 (2p + 5)
= (2p + 5)(p² + 3)
The number of girls int the choir is 4 times the number of boys in the choir. The total number of students in the choir is 60. How many girls are in the choir?
Answers
Answer:
15 boys in the choir
Step-by-step explanation:
60/4
4 x 15 = 60
Answer:
48
Step-by-step explanation:
First, make up some variables to represent the number of Girls and Boys in the choir.
B = number of boys
G = number of girls
You know that there are 4 times as many girls in the choir as boys. Therefore, the equation you can write is:
If you cross-multiply, then you get the simplified equation:
G = 4B
Intuitively this makes sense since if you multiplied the number of boys in the class by 4, that would be equal to the number of girls you have.
Now, we know that the total class size is 60. So girls plus boys equals 60:
G+B = 60
To solve the equation, replace the G in this equation with the replacement you found before, 4B.
G + B = 60 -->
4B + B = 60 -->
5B = 60 -->
B = 12
However, you are trying to find the number of girls, so plug the answer back into your equation.
G + B = 60 -->
G + 12 = 60 -->
G + 12 -12 = 60 - 12 -->
G = 48
The number of girls you have is 48.

The function h(x) in its simplest form is [tex]h(x) = 4log_2(x)- 2[/tex]
The functions are given as:

[tex]g(x) = log_2(x^3) - 4[/tex]
(a) Function h(x)This is given as:
[tex]h(x) = f(x) + g(x)[/tex]
So, we have:
[tex]h(x) = log_2(x) + 2 + log_2(x^3) - 4[/tex]
Collect like terns

[tex]h(x) = log_2(x) + log_2(x^3)- 2[/tex]
Apply law of logarithm

Company X has the following capital structure, which it considers to be optimal:
Debt =33%, Preferred stock = 28%, Common equity = 39%
Company X’s tax rate is 25% and investors expect earnings and dividends to grow at a constant rate of 6.5% in the future. Company X is expected to pay a dividend of $4.40 per share next year, and its stock currently sells at a price of $55 per share.
Company X can obtain new capital in the following ways:
Preferred: New preferred stock with a dividend of $13 can be sold to the public at a price of $109 per share.
Debt: Debt can be sold at an interest rate of 11%.
Calculate the following:
a. Cost of Common equity?
b. Cost of Preferred Equity?
c. Cost of debt?
d. Weighted Average Cost of Capital (WACC)
Answers
The computations of Company X's Capital Structure is as follows:
a. Cost of Common equity = 7.48% ($4.114/$55 x 100)
b. Cost of Preferred stock = 11.93% ($13/$109 x 100)
c. After-tax cost of debt = 8.25% (11% x 1 - 0.25)
d. Weighted Average Cost of Capital (WACC):
= (39% x 7.48% + 28% x 11.93% + 33% x 8.25%)
= (2.92% + 3.34% + 2.72%)
= 8.98%
= 9%
Data and Calculations:
Capital Structure Weights:
Weight of Debt =33%
Weight of Preferred stock = 28%
Weight of Common equity = 39%
Corporate tax rate = 25%
Earnings growth = 6.5%
Expected dividend per share next year = $4.40
Dividend per share for the current year = $4.114 ($4.40 x 93.5%)
Current common stock price per share = $55

Find the coordinates of the point.
The point is seven units to the left of the y-axis and two units below the x-axis.
Answers
Answer:
(-7, -2)
Step-by-step explanation:
If you look on a graph and travel 7 units to the left of the y axis, you are traveling in the x direction (along the x axis). Since you are 7 units to the left, you are at -7 in the x direction.
If you look on a graph and travel 2 units down below the x axis, you are traveling in the y direction (along the y axis). Since you are 2 units down, you are at -2 in the y direction.
Coordinates are listed in (x,y) format, so it would be (-7, -2)
