integrate the following:
[tex] \displaystyle \int \frac{ \cos(2x) - \cos(2a) }{ \cos(x) - \cos( \alpha ) } dx[/tex]
Answer:
[tex] \displaystyle 2 \sin(x) + 2x \cos( \alpha ) + \rm C[/tex]
Step-by-step explanation:
we would like to integrate the following integration:
[tex] \displaystyle \int \frac{ \cos(2x) - \cos(2 \alpha ) }{ \cos(x) - \cos( \alpha ) } dx[/tex]
notice that you can simplify the integrand
recall that,
[tex] \displaystyle \cos(2 \theta) = 2 \cos(\theta) ^{2} - 1[/tex]
thus substitute:
[tex]\displaystyle \int \frac{ 2\cos^{2} (x)- 1 - \{2\cos ^{2} (\alpha ) - 1 \} }{ \cos(x) - \cos( \alpha ) } dx[/tex]
remove parentheses:
[tex]\displaystyle \int \frac{ 2\cos^{2} (x)- 1 - 2\cos ^{2} (\alpha ) + 1}{ \cos(x) - \cos( \alpha ) } dx[/tex]
[tex]\displaystyle \int \frac{ 2\cos^{2} (x) - 2\cos ^{2} (\alpha ) }{ \cos(x) - \cos( \alpha ) } dx[/tex]
factor out 2:
[tex]\displaystyle \int \frac{ 2(\cos^{2} (x) - \cos ^{2} (\alpha )) }{ \cos(x) - \cos( \alpha ) } dx[/tex]
we can use algebraic identity i.e
a²-b²=(a+b)(a-b) to factor the denominator
[tex]\displaystyle \int \frac{ 2(\cos^{} (x) + \cos ^{} (\alpha ))( \cos(x) - \cos( \alpha ) ) }{ \cos(x) - \cos( \alpha ) } dx[/tex]
reduce fraction:
[tex]\displaystyle \int \frac{ 2(\cos^{} (x) + \cos ^{} (\alpha ))( \cancel{\cos(x) - \cos( \alpha ) ) }}{ \cancel{\cos(x) - \cos( \alpha ) }} dx[/tex]
[tex] \displaystyle \int 2( \cos(x) + \cos( \alpha ) )dx[/tex]
distribute:
[tex] \displaystyle \int 2 \cos(x) + 2\cos( \alpha ) dx[/tex]
use sum integration formula:
[tex] \rm \displaystyle \int 2 \cos(x) dx+ \int2\cos( \alpha ) dx[/tex]
recall integration rules:
[tex] \displaystyle 2 \sin(x) + 2x \cos( \alpha ) [/tex]
and we of course have to add constant of integration
[tex] \displaystyle 2 \sin(x) + 2x \cos( \alpha ) + \rm C[/tex]

Kirk drew a scale drawing of a petting zoo. The scale he used was 8 centimeters : 5 meters. The goat pen is 24 centimeters long in the drawing. How long is the actual pen?
The actual length of the pen is 15 meters
How to determine the actual length of the pen?The given parameters can be represented using the following ratio
Ratio = 8 centimeters : 5 meters
The scale length of the goat pen is given as
Scale length = 24 centimeters
So, we have
24 centimeters : Actual length = 8 centimeters : 5 meters
Rewrite as
24 : Actual length = 8 : 5 meters
Express as fraction
Actual length/24 = 5 meters/8
Multiply by 8
Actual length = 15 meters
Hence, the actual length of the pen is 15 meters

Answer:
2x + 2x + x - 8 = 4 (x + 2)
x = 16
Step-by-step explanation:
Because that's a square, the perimeter would be 4s where s is the measure of the side:
2x + 2x + x - 8 = 4 (x + 2)
To solve, refer below:
2x + 2x + x - 8 = 4x + 8
5x - 8 = 4x + 8
5x = 4x + 8 + 8
x = 16

Step-by-step explanation:
We are given the equation [tex]\frac{n^4}{p^2} + \frac{n^2}{p^3}[/tex]
To solve we need to first find the LCM of the denominators, which would be [tex]p^3[/tex].
[tex]\frac{n^4p}{p^3} + \frac{n^2}{p^3}[/tex]

An oatmeal container has a diameter of 20 cm and can hold 1570 cm3 of oatmeal. What is the height of the container of oatmeal
Answer:
5 cm approx
Step-by-step explanation:
Given data
Diameter= 20cm
radius= 10cm
Volume= 1570cm^3
We know that the expression for the volume of the container/cylinder is
V= πr^2h
1570= 3.142*10^2*h
1570=3.142*100*h
1570=314.2h
h= 1570/314.2
h=4.99 cm
Hence the height is 5 cm approx

Max has a collection of 99 dimes and pennies worth $4.41. How many pennies does he have?
Answer:
61 pennies
Step-by-step explanation:
d + p = 99
0.1d + 0.01p = 4.41
d = 99 - p
0.1(99 - p) + 0.01p = 4.41
9.9 - 0.1p + 0.01p = 4.41
-0.09p = -5.49
p = 61
Answer: 61 pennies
Which type of interest can be described as interest that is earned on the principal amount only
Simple interest is the type of interest that is earned on the principal amount only.
What is Interest?Interest in simple terms is the extra amount that you have to pay if you borrow money or the extra money you get if you lend the money.
Simple interest is one of the type of interest.
Simple interest is defined as the interest obtained over the principal amount on a certain rate.
Suppose that, a certain transaction has an annual interest rate of 2% for a period of 10 years.
If the principal amount is P, then in simple interest, interest will be a fixed amount, that is, 2% of P, in the whole period.
In compound interest, the interest will be compounded each of the year or month or quarterly depending on the criterion.
Hence the type of interest described here is simple interest.

Angelo rode his bike around the trail that was 1/4 of a mile long. He rode his bike around the trail 8 times. Angelo says he rode a total of 8/4 miles. Terresa says he is wrong and that he actually rode 2 miles. Who is correct? Use your words to explain how you know?
Answer:
They both are correct
Step-by-step explanation:
It is given that :
The length of the trail is = 1/4 of a mile
Angelo rode his bike around the trail = 8 times
So Angelo said that he rode his bike around the trail for = 8/4 miles
Terresa says Angelo actually rode his bike = 2 miles
They both are correct as 8/4 mile is equal to 2 miles in the simplified form.
So both of them are correct.
what is the length of RU?
Answer:
Length of RU is 20 units.
Step-by-step explanation:
In ΔRSt and ΔRUT,
ST ≅ TU [Given]
RT ≅ RT [Reflexive property]
∠RTS ≅ ∠RTU [Both the angles are the right angles]
ΔRTS ≅ ΔRTU [By SAS property of congruence]
Therefore, RS ≅ RU [By CPCTC (corresponding parts of the congruent triangles are congruent]
8x = 6x + 5
8x - 6x = 5
2x = 5
x = 2.5
Length of RU = (6x + 5)
= 6(2.5) + 5
= 15 + 5
= 20
Length of RU is 20 units.
