Solve each equation for 0 ≤ θ 2π -2√2=-4sin 2θ

Answers

Answer:

Step-by-step explanation:

Begin by dividing both sides by -4 to get:

[tex]\frac{\sqrt{2} }{2}=sin2\theta[/tex] and then take the inverse sin of both sides to get

[tex]sin^{-1}(\frac{\sqrt{2} }{2})=2\theta[/tex] (the inverse sin undoes the sin on the right). Now we need to look on our unit circle to find the angles where [tex]sin(\frac{\sqrt{2} }{2})[/tex] is positive. There are 2 places. Sin is positive in both QI and QII. The angles are

[tex]\frac{\pi}{4},\frac{3\pi}{4}[/tex]. Therefore, our 2 equations are

[tex]\frac{\pi}{4}=2\theta[/tex]  and  [tex]\frac{3\pi}{4}=2\theta[/tex].  Solving the first equation:

[tex]\theta=\frac{\pi}{8}[/tex]

and the second equation:

[tex]\theta=\frac{3\pi}{8}[/tex]

What is the center of the circle (x+7)^2+(y+4)^2=25

Answers

9514 1404 393

Answer:

  (-7, -4)

Step-by-step explanation:

Compare the given equation to the standard form equation for a circle with center (h, k) and radius r.

  (x -h)^2 +(y -k)^2 = r^2

You see that ...

  -h = +7   ⇒   h = -7

  -k = +4   ⇒   k = -4

Then the center is ...

  (h, k) = (-7, -4)

__

The radius is ...

  r^2 = 25   ⇒   r = √25 = 5 . . . radius of the circle

Solve for x.
5(x - 10) = 30 – 15x
O x= 1
O x = 4
O x = 5
O x = 8

Answers

Answer:

X=4

Step-by-step explanation:

Distribute  

5(x−10)=30−15x

5 − 5 0 = 3 0 − 1 5

Rearrange terms

5x−50=30−15x

5 − 5 0 = − 1 5 + 3 0

Add  5 0  to both sides of the equation

5x-50+50=-15x+30+50

Add  1 5  to both sides of the equation

5 + 1 5 = − 1 5 + 8 0 + 1 5 \

2 0 /2 0 = 8 0/ 2 0

= 4

Option B is correct, the value of x in the equation 5(x - 10) = 30 – 15x is 4,

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is 5(x - 10) = 30 – 15x

Five times of x minus ten equal to thirty minus fifteen times of x.

x is the variable in the equation

Apply distributive property on left hand side

5x-50=30-15x

Take the variables on one side and constants on other side

5x+15x=30+50

Combine the like terms

20x=80

Divide both sides by 20

x=4

Hence, the value of x in the equation 5(x - 10) = 30 – 15x is 4, option B is correct.

Step-by-step explanation:

Very simple. We find the area of the circle, A=Pi Radius Square.

So 3.14 (15x15)

A≈706.86

The bottom shape is 706.86x24=16964.64

The top is a cone, meaning its V≈3769.91

So 3769.91+16964.64=17734.55

Step-by-step explanation:

Answer:

It is in fact the second one.

Step-by-step explanation:

It says that he bought a total of 7 tickets and it cost $32.

x represents the number of adult tickets and y represents the number of chid tickets.

So:

x + y = 7 because the adding the number of adult and child tickets should equal the total number bought.

and

8x + 2y = 32 because each adult ticket was 8 dollars and each child was 2 and the total should add up to 32
