help me in this too pls​

Hello!

[tex]\large\boxed{\frac{2\pi}{3} \text{ and } \frac{4\pi}{3}}[/tex]

2cosФ + 1 = 0

Begin by isolating for cosФ. Subtract both sides by -1:

2cosФ = -1

Divide both sides by 2:

cosФ = -1/2

Using the unit circle, we know that from [0, 2π), values that have a cosine of -1/2 are 2π/3 and 4π/3.

Therefore, the solutions of this equation are:

Ф = 2π/3 and 4π/3

Answer:

[tex]A=190.75\ cm^2[/tex]

Step-by-step explanation:

The diameter of a hemisphere, d = 9 cm

Radius, r = 4.5 cm

We need to find the surface area of the paperweight. The formula for the surface area of a hemisphere is given by :

[tex]A=3\pi r^2\\\\A=3\times 3.14\times (4.5)^2\\\\A=190.75\ cm^2[/tex]

So, the surface area of the paperweight is [tex]190.75\ cm^2[/tex].

Answer:

x=0.5

Step-by-step explanation:

Simplifying

4x + -3(2x + -1) + -4x = 0

Reorder the terms:

4x + -3(-1 + 2x) + -4x = 0

4x + (-1 * -3 + 2x * -3) + -4x = 0

4x + (3 + -6x) + -4x = 0

Reorder the terms:

3 + 4x + -6x + -4x = 0

Combine like terms: 4x + -6x = -2x

3 + -2x + -4x = 0

Combine like terms: -2x + -4x = -6x

3 + -6x = 0

Solving

3 + -6x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + -6x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + -6x = 0 + -3

-6x = 0 + -3

Combine like terms: 0 + -3 = -3

-6x = -3

Divide each side by '-6'.

x = 0.5

Simplifying

x = 0.5

kamal needs to buy 84 in of wire.

Step-by-step explanation:

multiply the length value by 12:

if he wants 7 feet, and the store only sells it in inches, then we know what a foot is twelve inches so 12x7=84.

Answer:

The area would be 153.86

Step-by-step explanation:

Since the diameter is 14, the radius would be 7.

The area is pi times the radius squared.

7 squared is 49.

If your using 3.14 for pi, then its 3.14 times 49.

That gives you 153.86.

Answer:

The conclusion of the Mean Value Theorem says that there is a number

c

in the interval

(

1

,

3

)

such that:

f

'

(

c

)

=

f

(

3

)

−

f

(

1

)

3

−

1

To find (or try to find)

c

, set up this equation and solve for

c

.

If there's more than one

c

make sure you get the one (or more) in the interval

(

1

,

3

)

.

For

f

(

x

)

−

−

x

−

x

, we have

f

(

=

, and

f

(

)

=

−

+

=

−

19

Also,

f

'

(

x

)

=

−

x

−

.

So the

c

we're looking for satisfies:

f

(

=

c

=

(

So we need

c

=

−

9

. And

c

=

2

.

Note:

I hope you've been told that actually finding the value of

c

is not a part of the Mean Value Theorem.

The additional question"find the value of

c

" is intended as a review of your ability to solve equations. For most functions, you will not be able to find the

c

that the MVT guarantees us is there..

Answer:

x = -1

Step-by-step explanation:

Simplify by starting in the innermost parentheses and moving outwards:

[tex]1 + 3(1 + 3(1 + 3(1+x)))=13\\1 + 3(1+3(1+3 + 3x)) = 13\\1 + 3(1 +3(3x + 4)) = 13\\1 + 3(1 + 9x + 12)) = 13\\1 + 3(9x + 13) = 13\\1 + 27x + 39 = 13\\27x + 40 = 13\\27x = -27\\x = -1[/tex]

Answer:

b. Not binomial: there are more than two outcomes for each trial.

Step-by-step explanation:

Binomial probability distribution:

We need

Fixed number of trials.

Independent trials.

Each trial can be reduced to a yes/no proposition.

Rolling a single "loaded die 19 times, keeping track of the numbers that are rolled.

There are six possible outcomes(1,2,3,4,5,6), so cannot be reduced to a yes/no proposition, and the answer is given by option b.

Step-by-step explanation:

Answer:  1/6 is greater than 1/24

=========================================================

Explanation:

Let's assume that 1/6 is equal to 1/24 for now. We'll see later this is false.

1/6 = 1/24

1*24 = 6*1 .... cross multiply

24 = 6

The last equation is false, so the first equation is false.

To fix things, we need to replace every equal sign with a greater than sign like so

1/6 > 1/24

1*24 > 6*1

24 > 6

Now each of those three statements are true, since the last statement is true. This shows that 1/6 is greater than 1/24.

----------------

We can take another approach to use the calculator to see that

1/6 = 0.167 approximately

1/24 = 0.042 approximately

We can see that 0.167 is the larger decimal, so 1/6 is the larger fraction.

If you want, you can move the decimal point over 3 spots to the right for each decimal number. So that would mean 0.167 becomes 167, and 0.042 becomes 42. Then it becomes more clear that 167 is the larger value, helping confirm that 0.167 is the larger decimal.

Answer:

The coefficients of x are different in the expressions, but the constant values are the same. Zero times any value is zero, so both expressions will be equal to -5.9. If Ryan tried any other number, he would see that the expressions are not equivalent.
