The Cosine Function

The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:

[tex]y=\cos x[/tex]

Both the amplitude A and the angular frequency w of a cosine can be modeled by the function

[tex]y=A\cos(\omega x)[/tex]

The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:

[tex]\frac{\pi}{2}\omega =2\pi[/tex]

Thus:

[tex]\omega = 4[/tex]

Therefore, the equation of the sinusoid is:

[tex]y=3\cos (4x)[/tex]

Answer:12

Step-by-step explanation:

Given

Each coin roll can hold 40 quarters

There are a total of 479 quarters

So, no of coin roll [tex]=\dfrac{\text{Total quarters}}{\text{Holding capacity of each coin roll}}[/tex]

[tex]\Rightarrow \frac{479}{40}=11.975[/tex]

As no of coin rolls cannot be in decimal

[tex]\therefore[/tex] there are 12 coin rolls

Answer:

hello your question is incomplete attached below is the complete question

answer; [tex]\frac{\pi ^{2} }{16}[/tex]

Step-by-step explanation:

attached below is a detailed solution to the given question above

where :

cos 2x = 1-2sin^2x

cos2x = 2 cos^2x -1

sin^2 2x + cos^2 2x = 1

1-cos^2 2x = sin^2 2x

Answer:

[tex]\mathbf{ Volume (V) = \dfrac{\pi^2}{16} }[/tex]

Step-by-step explanation:

[tex]y = sin x .cos x \\ \\ A(x) = \pi [ sin \ x * cos \ x]^2[/tex]

[tex]= \pi sin^2 x* cos ^2x[/tex]

[tex]Volume (V) = \int ^{\pi/2}_{0} \pi \ sin^2 x \ cos^2x \ . dx[/tex]

[tex]=\pi \int ^{\pi/2}_{0} \Bigg [ \dfrac{1-cos \ 2x}{2} \times \dfrac{1 + cos \ 2x}{2} \Bigg ] \ . dx[/tex]

[tex]=\dfrac{\pi}{4} \int ^{\pi/2}_{0} \ [1 - cos^2 \ 2x] \ . dx[/tex]

[tex]=\dfrac{\pi}{4} \int ^{\pi/2}_{0} sin ^2 2x \ . dx[/tex]

[tex]=\dfrac{\pi}{4} \int ^{\pi/2}_{0} \ \dfrac{1-cos \ 4x}{2} \ . dx[/tex]

[tex]=\dfrac{\pi}{8} \int ^{\pi/2}_{0} \ (1-cos \ 4x) \ . dx[/tex]

[tex]=\dfrac{\pi}{8} \Bigg [x - \dfrac{sin \ 4x}{4} \Bigg]^{\pi/2}_{0}[/tex]

[tex]=\dfrac{\pi}{8} \Bigg [(\dfrac{\pi}{2} -0)-0 \Bigg][/tex]

[tex]\mathbf{ =\dfrac{\pi^2}{16} }[/tex]

Answer: 79

Step-by-step explanation:

Answer:

79

Step-by-step explanation:

95 total

3x8=24

24 - 95= 71

3 divided by 24=8

71+8=79

1 1/5 - 3/5 = 3/5

9 1/5 - 3/5 = 8 3/5

Answer:

1: 3/5 2: 8 3/5

Step-by-step explanation:

1 3/5 becomes 6/5. 6/5 - 3/5 = 3/5. 9 1/5 becomes 46/5. 46/5 - 3/5 = 43/5. 5*8=40 so 8 3/5.

Answer:

A) interest in the amount of $1,600

Sorry, this is late!

Step-by-step explanation:

Line 2 states that a taxpayer is ineligible to use the form if their total taxable interest is over $1,500. Answer A implies that the interest rate is $1,600 which applies perfectly.

The thing on line 2 that would make the taxpayer ineligible to use this form is D, None of the above.

This refers to the tax form in the United States that is used for people below the age of 65 and have dependents that earn less than $100,000 yearly.

Hence, we can see from line 2, we can see that it is stated that taxable interest is more than $1,500 and the person becomes ineligible and none of the answer choices satisfies this, so option D is the answer.

Answer: $382.25

Step-by-step explanation: Subtract 68.50 from 164.25, then add 286.50.

its a sqaure so the angles are 90 degress each.

90 - 38 = 52

answer: C. 52

Answer:

c = 52*

Step-by-step explanation:

If we assume that both shaded triangles are equivalent, and we know that the total angle of a square's corner is 90*, to find the missing angles of the unshaded area (angle z) we just subtract 38 from 90.

90 - 38 = 52*.

Answer:

class A 20/25 = 4/5

class B 24/30 = 4/5

they are both the same

Answer:

Both classes have the same fraction (80% or 4/5).

Step-by-step explanation:

20 is 4/5 of 25, so 80% of students in Class A passed in first class.

24 is 4/5 of 30, so 80% of students in Class B passed in first class.

Both 20/25 and 24/30 simplify to 4/5, or 80%, so both classes have the same fraction of students passing.
