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

Which equation represents the solution of the linear equation - 4x + 5 = 9?
A. x = 4
B. x = 1
C. x = -1
D. x = -4
Solve for x.
5(x - 10) = 30 – 15x
O x= 1
O x = 4
O x = 5
O x = 8
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.

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

someone please help
Answer:
17734.55 inches cubed. If you found this helpful, love the answer! Thank you :D
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

Two cyclists, 68 miles apart, start riding toward each other at the same time. One cycles 3 miles per hour faster than the other, and they meet after 4 hours of riding.
a. Write an equation using the information as it is given above that can be solved to answer this problem. Use the variable r to represent the speed of the slower cyclist.
b. What are the speeds of the two cyclists? _______________
Answer:
4r + 4(r + 3) = 68
r = 7 miles per hour
r + 3 = 10 miles per hour
Step-by-step explanation:
distance = rate * time
a)
4r + 4(r + 3) = 68
Distribute
4r + 4r + 12 = 68
8r + 12 = 68
8r = 56
r = 7 miles per hour
r + 3 = 10 miles per hour
a) The given equation using the information as it is given above that can be solved to answer this problem is 4r + 4(r+3) = 68
b) The speed of both cyclists are 3mi/hr and 10mi/hr respectively
The formula for calculating the distance covered is expressed as:
Distance = speed * time
Let the speed covered by one cyclist be t
If one cycles 3 miles per hour faster than the other, the speed of the other will be t + 3
If both meet after 4 hours of riding, then their time will be 4 hours
Distance covered the first cyclist = 4r
Distance covered by the second = 4(r+3)
If the two cyclists are 68 miles apart, then:
4r + 4(r+3) = 68
a) The given equation using the information as it is given above that can be solved to answer this problem is 4r + 4(r+3) = 68
b) Expand the equation in a to get "r"
4r + 4r + 12 = 68
8r + 12 = 68
8r = 68 - 12
8r = 56
r = 56/8
r = 7miles per hour
Speed of the first cyclist = 7mi/hr
Speed of the second cyclist = 3 + 7mi/hr = 10mi/hr
Hence the speed of both cyclists are 3mi/hr and 10mi/hr respectively
