Given

sin(x) - sin(4x)

= 2 cos (( x + 4x)/2) * sin ( ( x - 4x) / 2))

= 2 cos 5x/2 • sin -3x / 2

= - 2 cos 5x/2 • sin 3x/2

Hope it helps :)❤

The sum sin(x) - sin(4x) can be written as a product as 2 sin (5x/2) cos (3x/2).

Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.

The main three trigonometric ratios are sine, cosine and tangent functions.

We have the trigonometric formula that,

sin A - sin B = 2 sin ([tex]\frac{A+B}{2}[/tex]) cos ([tex]\frac{A-B}{2}[/tex])

Here the sum is, sin(x) - sin(4x) where A = x and B = 4x.

sin(x) - sin(4x) = 2 sin ((x+4x)/2) cos ((x-4x)/2)

                       = 2 sin (5x/2) cos (-3x/2)

We also have, cos(-x) = cos(x).

So, sin(x) - sin(4x) = 2 sin (5x/2) cos (3x/2)

Hence the product form is sin(x) - sin(4x) = 2 sin (5x/2) cos (3x/2).

No, 1/2x+3/4-5/8x-7/8 and 1/8(x+1) are not equivalent expressions.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given expression is 1/2 x+3/4-5/8 x-7/8

Now, 1/2 x-5/8 x+3/4-7/8

-1/8 x- 1/8

-1/8(x+1)

Therefore, the equivalent expression for the given expression is -1/8(x+1).

Answer: 5 terms.

Step-by-step explanation:

We know that the n-th term of a sequence is:

Aₙ = n² + 20

Where n can be any natural number, then n ∈ {1, 2, 3, ...}

We want to find how many terms are smaller than 50.

Then we could find the first value of n such that Aₙ is equal or larger than 50.

Then we can solve:

Aₙ = n² + 20 = 50

then:

n² = 50 - 20 = 30

n = √30 = 5.48

This is not a natural number, so we need to round to the next one that is n = 6

This means that the first natural number n such that Aₙ is equal or larger than 50 is n = 6, then for the values:

n = 1, 2, 3, 4, 5

Aₙ is smaller than 50

This means that there are 5 terms of the sequence that are smaller than 50.

There is no limit to how many figures you can create. There is not enough information to solve this. If this is only a part of the question, try to include all of it.

Answer: I disagree. If Pablo has enough time to make 10 figures. He could make 8 of the large figures and make $80.00 and then make 2 of the large figures and make $16. Together with the 8 small and 2 large figures they would make $96.00

Ungrouped data

Step-by-step explanation:

The ungrouped data is the data where it has only individual data points that means it does not have a frequency distribution

So according to the given situation

Since it is mentioned that , 4, 10, 3, 3, 4, 7, 4, 6, 5, 11, 9, 5, 7 so this represent the ungrouped date

Answer:

Step-by-step explanation:

All triangles without exception, have 180 degrees.

x + 53 + 70 = 180                Add the left

x + 123 = 180                       Subtract 123 from both sides.

x + 123 - 123 = 180 - `123    Combine.

x = 57

Answer:

The radius of the arc is 5

Step-by-step explanation:

An arc is a part of the circumference of a circle that has been cut out. It can be best understood as an incomplete circle. The length of the arc is how long the arc is.

The formula relating how long the arc is with its radius is

length of arc = [tex]\frac{\theta}{360} \times 2 \pi R[/tex]

where R is the radius we are looking for.

Θ = 135 which can be seen as the arc angle

[tex]R =\frac{l \times 360}{\theta \times 2 \pi} =\frac{(15 \pi /4) \times 360 }{135 \times 2 \pi}=5[/tex]

The radius of the arc = 5

The side length does not matter here because it's useless unless you're trying to find the perimiter of a triangle, which has a completely different algorithm. It is called the Pythagorem Theorum. I just learned the Pythagorem Theorum last class, and it isn't too difficult once you get the hang of it. Wow I went off course. Anyways I hope this helps!
