The required solutions to sin(2x) = 2cos(x) are the following as :  [tex]\:x=\frac{\pi }{2}+2\pi n,\:x=\frac{3\pi }{2}+2\pi n[/tex].

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

The equation of trigonometry functions is given in the question:

sin(2x) = 2cos(x)

We have to determine the solution to the given trigonometry equation

As per the question, we have

⇒ sin(2x) = 2cos(x)

Rewrite the above trigonometry equation,

⇒ sin(2x) - 2cos(x) = 0

⇒ 2sin(x)cos(x) - 2cos(x) = 0

Common factor out from the equation,

⇒ 2cos(x)[sin(x) - 1] = 0

Solving each part separately

2cos(x) = 0 and sin(x) - 1 = 0

cos(x) = 0 and sin(x) = 1

[tex]\:x=\frac{\pi }{2}+2\pi n, and \:x=\frac{3\pi }{2}+2\pi n[/tex].

Thus, the required solutions to sin(2x) = 2cos(x) are the following:  [tex]\:x=\frac{\pi }{2}+2\pi n,\:x=\frac{3\pi }{2}+2\pi n[/tex].

Answer:

Option D: 66 degrees

Step-by-step explanation:

Interior angles of a triangle add up to 180 degrees.

Thus, 90+24+x=180 would be the equation you make to solve:

90+24+x=180

114+x=180

x=66

So <x=66 degrees

The answer is B) 122 degrees

Answer:

Step-by-step explanation:

The current that flows through most substances is directly proportional to the voltage V applied to it. The German physicist Georg Simon Ohm (1787–1854) was the first to demonstrate experimentally that the current in a metal wire is directly proportional to the voltage applied: I∝V I ∝ V .

Just substitute the number on the x side of the table for x in the equation and solve to get the y value.

The completed table of Y values using the function rule y = 4 + 4x is as follows:

X     Y

2     12

3     16

4     20

10    44

To fill in the Y values using the function rule y = 4 + 4x, we substitute the given X values into the equation and solve for Y.

When the value of X = 2:

4 + 4(2) = 4 + 8 = 12

When the value of X = 3:

4 + 4(3) = 4 + 12 = 16

When the value of X = 4:

4 + 4(4) = 4 + 16 = 20

When the value of X = 10:

4 + 4(10) = 4 + 40 = 44

The completed table is as follows:

X     Y

2     12

3     16

4     20

10    44

Hi, you've asked an incomplete question. I attached the missing caption that completes the question.

Explanation:

By looking closely at the caption we notice there are measuring coordinates along the margin of the caption. To find the middle of the chairs, take note of the total coordinate distances between points C and D;

Substracting both differences in distances we get 2 (4-2) so at point (10, 7) we find the middle or halfway between the chairs at points C  and D.

The length of side of original square is: 20 inches

Step-by-step explanation:

Let x be the length of side of original square

Then x+5 will be the side of new square

Th formula for perimeter is:

[tex]P = 4*side[/tex]

As we know the perimeter of the new square we can use the perimeter to find the value of x

[tex]100 = 4 * (x+5)\\100 = 4x+20\\4x = 100-20\\4x = 80\\\frac{4x}{4} = \frac{80}{4}\\x = 20[/tex]

The value of x is 20 inches.

Hence,

The length of side of original square is: 20 inches

Answer:so the standard form is y = mx + b

m is the slope (rise/run)

b is the y-intercept or where the slope intercepts the y-axis

so you end up with
