(cos²x-sin²x)²-sin4x+sin²2x=0

or, cos²2x-sin4x+sin²2x=0

You do the opposite function to find your answer

Answer:

1. t = 21

2. s = 2

3. c = 6

4. v = 45

Step-by-step explanation:

1. t - 19 = 2

*Add 19 to both sides.

t = 21

2. 1 + s = 3

*Subtract 1 from both sides.

s = 2

3. 24 = 4c

*Divide each side by 4.

6 = c

4. v/5 = 9

*Multiply each side by 5.

How do I solve this problem: 6c - 8 - 2c = -16

Answers

Answer:

c = -2

Step-by-step explanation:

6c-8-2c = -16

4c -8 =-16

4c = -16 +8

4c = -8

4c/4 = -8/4

c = -2

Answred by Gauthmath

The solution of the equation 6c - 8 - 2c = -16 is -2 calculated by combining like terms and isolating the variable then dividing the equation by coefficient of the c variable.

To solve the equation 6c - 8 - 2c = -16, isolate the variable c on one side of the equation.

Combine like terms on the left side of the equation:

6c - 2c = 4c

The equation now becomes:

4c - 8 = -16

Take constant term on the right side of the equation by adding 8 to both sides:

4c - 8 + 8 = -16 + 8

The equation simplifies to:

4c = -8

To find the value of c, divide both sides of the equation by 4:

4c / 4 = -8 / 4

c = -2

Hence, the value of c is -2 in the equation  6c - 8 - 2c = -16.

Answer:

1.

a rectangular prism is simply a block. it has length, width and height. and similar to the area of a rectangle (length×width) we get as volume length×width×height.

other than that we only need to consider that a volume always has cubic units (like cm³, m³, ft³, ...).

the volume of a cylinder is again ground area times height, when we imagine the cylinder to stand on it circular side.

and the states standard formula (hi, internet !) for the volume of a cylinder is pi×r²×height

so, we have 75×20×14 = 21,000 cm³

and pi×75²×120 = pi×5625×120 = 2,120,575 cm³

so, the cylinder has a much bigger volume.

3.a.

the standard formula for the volume of a pyramid (hi, internet !) is length×width×height/3

the diagram means that it is a square pyramid (the ground area is a square). therefore all sides of the ground area are of equal length. length = width

so, we have 64×64×40/3 = 54631.333... m³

3.b.

as the description says, 5000 people fit in, so, to find how much volume is there available per person, we need to divide the volume by 5000.

54631.333... / 5000 = 10.923 m³

Step-by-step explanation:

and again, you need only to search the formulas on the internet, and then calculate this with the given numbers yourself, and you will be much faster than paying things here and waiting for answers and copy/pasting things.

again, there is practically nothing to explain, just to use the standard formulas and the calculator. what's the problem ?

I will gladly explain to you concepts you have not understood (that is the point of Brainliest). but I and others here are not your personal slaves to do your work for you.

Find m angle AFE.


Please I need help badly

Answers

It’s 173. Add all the given angles and so AFD is 116. Then you can see that angle DFE has the same angle marking as BFC which means they must have the same measure. So 116+57=173. Hope this helps.

The measure of the angle AFE or m∠AFE is 173 degrees option (B) 173 is correct if the angle AFB = 25 degrees, Angle BFC = 57 degrees, Angle CFD = 34 degrees, and Angle DFE = 57 degrees.

What is an angle?

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

We have angles shown in the picture.

Angle AFB = 25 degrees

Angle BFC = 57 degrees

Angle CFD = 34 degrees

Angle DFE = 57 degrees

Angle AFE is the sum of the angle AFB, Angle BFC, Angle CFD, and Angle DFE.

Angle AFE = Angle AFB + Angle BFC + Angle CFD + Angle DFE

Angle AFE = 25 + 57 + 34 + 57

Angle AFE = 173 degrees

Thus, the measure of the angle AFE or m∠AFE is 173 degrees option (B) 173 is correct if the angle AFB = 25 degrees, Angle BFC = 57 degrees, Angle CFD = 34 degrees, and Angle DFE = 57 degrees.

Magnitude of angle D = 170
Because,
Sum of interior angles of a pentagon = 540 degree
That is,
Angle A + angle B + angle C + angle D + angle E = 540 degree
87degree + 125 degree + 63 degree + 95 degree + angle D = 540 degree

So that gives angle D = 170 degree

Hope this helps.
ArmyCee:)

Answer:

m<D = 170°

Step-by-step explanation:

In a pentagon, the angles add up to 540°. This means the sum of <A, <B, <C, <D, and <E add up to that, and we can write an equation:

m<A + m<B + m<C + m<D + m<E = 540°

We are already given the measures of all the angles except D, so we can substitute them in:

87° + 125° + 63° + m<D + 95° = 540°

Now, we can simplify and solve for <D:

m<D + 370° = 540°

m<D = 170°

The actor stands alone, saying his lines. However, when you see the actual movie, he is talking to a formidable seven-foot-tall monster in a creepy dark forest. A process called blue-screen technology is used to insert images into a background. Today, moviemakers use this process to combine digitally created, or computer-generated, characters with real people on the screen. Here's how it works:The scene calls for a real character to interact with a seven-foot-tall digitally created monster. First, the real character's part must be filmed. He may rehearse with another actor who plays the part of the monster. During the rehearsal, the "monster" might wear a tall hat to represent the stature of the monster. The real actor practices looking at the top of the hat during the scene so that it seems that he is looking up at a very tall creature. The actor gets used to where the monster stands and moves. The monster's movements are marked on the floor so that the actor doesn't walk on top of the monster during the scene. Then it is time for the scene to be shot. The actor stands alone in front of a blue screen and delivers his lines as if the monster were there. Eventually, the blue background is deleted, using a computer, and images of the digital monster and background are then transferred to the film.Which of the following is a reasonable conclusion to draw from the reading?a.Scenes with seven-foot-tall monsters are easy to add with blue-screen technology.b.Movies are more fun to watch because of blue-screen technology.c.Adding special effects to movies using blue-screen technology isn't worth the effort.d.As a result of blue-screen technology, adding special effects to movies is easier and faster.
