Answer:

576 cm^3

Step-by-step explanation:

Express this volume formula as V = π r^2 h, where the " ^ " symbol indicates exponentiation. Substitute 4 for r (this is half the diameter), 12 cm for h, and 3 for π: V = 3*(4)^2*12 cm^3, or V = 576 cm^3.

Cos(100)-cos(99)=? Can you do it step by step

Svetllana [295]

Let's see what to do buddy...

________________________________

If 99 & 100 are in Degree

_________________________________

STEP (1)

The angles 99 and 100 are in the second quarter of the trigonometric circle.

The cosine is negative in the second quarter.

To make things easier, we can use angle conversion.

Look :

$we \: know \: that \: 100 = 90 + 10$

$also \: we \: know \: 99 = 90 + 9$

So :

$\cos(100) = \cos(90 + 10) = \cos( \frac{\pi}{2} + 10 ) \\$

$\cos(99) = \cos(90 + 9) = \cos( \frac{\pi}{2} + 9 ) \\$

_________________________________

STEP (2)

Well now we have to do the arc deletion.

To remove the arc, we remove π/2 from the arc.

Remember that every time we remove π/2 from the arc, the trigonometric ratio changes.

That is, if it is a sine, it becomes a cosine, and if it is a cosine, it becomes a sine.

Or if it is a tangent, it becomes a cotangent, and if it is a cotangent, it becomes a tangent.

$in \: second \: quarter \: cosine \: is \: negative \\ \\ \cos( \frac{\pi}{2} + 10 ) = - \sin(10) = - 0.173$

$\cos( \frac{\pi}{2} + 9 ) = - \sin(9) = - 0.156 \\$

_________________________________

STEP (3)

$\cos(100) - \cos(99) = \\ - \sin(10) - ( - \sin(9) \: ) = \\ - 0.173 - ( - 0.156) = \\ - 0.173 + 0.156 = - 0.017$

And we're done here.

_________________________________

If 99 & 100 are in Radian

_________________________________

STEP (1)

First we need to know how many degrees 1 radian is.

The following equation is used to convert degrees to radians or radians to degrees.

$\frac{degree}{180} = \frac{radian}{\pi} \\$

So we have :

$\frac{d}{180} = \frac{1}{\pi} \\$

Multiply the sides of the equation by 180 :

$d = \frac{180}{\pi} = \frac{180}{3.14} = 57.32 \\$

So 1 radian is approximately equal to 57 degrees.

And we have :

$100 \: rad \: = 100 \times 57 = 5700 \: deg \\ \\ 99 \: rad \: = 99 \times 57 = 5601 \: deg$

_________________________________

STEP (2)

Let's move on to deletion.

Look : 5700° = 15 × 360° + 300°

and : 5601° = 15 × 360° + 201°

We know π rad = 3.14 × 57 = 180° deg

So 2π rad = 2 × 180 = 360 ° deg

Then :5700 = 15 × 2 π + 300° = 30 π + 300°

and :5601 = 15 × 2 π + 201° = 30 π + 201°

Remember that deleting 2π is unconditional.

$\cos(30\pi + 300) = \cos(300) = \cos(360 - 60) = \cos(2\pi - 60) = \cos( - 60) = \\ cosine \: eat \: negative \\ \cos( - 60) = \cos(60) = \frac{1}{2}$

$\cos(30\pi + 201) = \cos(201) = \\ \cos(180 + 21) = \cos(\pi + 21) = \\ - \cos(21) = - 0.933$

$\frac{1}{2} - ( - 0.933) = 0.500 + 0.933 = 1.433$

And we're done.

Thanks for watching buddy good luck.

Evaluate the expressions

likoan [24]

<h3>Answer:</h3>

1. x + 20

2. 0

3. 2x - 8

4. 95x + 10

5. -9x - 6

6. 4x + y - 5

7. -x + 6y + 5

8. x + y - 15

9. x + 4y + 4

<h3>Step-by-step explanation:</h3>

• When working with variables and numbers, you have to put the variables first (in alphabetical order) and then the numbers.

• To evaluate an algebraic expression, we find the value of the expression when the variable is replaced by a given number.

• To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

• When we are not given a number for the variable in the expression, we have to group like-terms.

Example: 5x + 6 + 3x - 2 - y

1st: group 5x and 3x (add the terms together) = 8x
2nd: group 6 and -2 (add the terms together) = 4
3rd: Since -y has no like-terms, we can't group it = -y
Fourth, put the terms in order (variables = alphabetical order and then numbers) = 8x - y + 4

1. 4x + 12 - 3x + 8

4x - 3x = 1x = x
12 + 8 = 20
x + 20

2. -8x + 1 + 2x - 1 + 6x

-8x + 2x + 6x = -8x + 8x = 0
1 - 1 = 0
0

3. 4x - 3 - 2x - 5

4x - 2x = 2x
-3 - 5 = -8
2x - 8

4. 100x + 5 - 5x + 5

100x - 5x = 95x
5 + 5 = 10
95x + 10

5. -4x - 4 - 2 - 5x

-4x - 5x = -9x
-4 - 2 = -6
-9x - 6

6. 2x - 1 + 2x - 4 + y

2x + 2x = 4x
-1 - 4 = -5
4x + y - 5

7. 5y - x + 2y - y + 5

5y + 2y - y = 5y + 1y = 6y
-x + 6y + 5

8. -15 + 3y - 3x - 2y + 4x

3y - 2y = 1y = y
-3x + 4x = 1x = x
x + y - 15

9. 4 - 3y + 3x - 2x - y

-3y - y = 4y
3x - 2x = 1x = x
x + 4y + 4
