Answer:
Step-by-step explanation:
The simplest way to do this is to break in into parts
2 * 4 = 810^6 * 10^2 = 10^8 Notice that when you multiply base 10 powers, you add the powers. That's the key to scientific notation.When you combine these two you get 8 * 10^8

If two angle measurements are 53° and 70,° what must the third angle measurement equal to form a triangle?
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

Write the sum as a product.
sin(x)-sin(4x)
Step-by-step explanation:
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).
What are Trigonometric Ratios?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).

The length of the 135˚ arc below is 15/4 π. Find the radius of the circle. Please explain the answer.
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
