A glass paperweight is shown below.
The paperweight is a hemisphere with diameter 9cm..
Find the surface area of the paperweight.

Answers

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].

I’m pretty sure the coefficient would be 5, sorry if I’m wrong.

Answer: 3

Step-by-step explanation:

A term is a group of numbers and variables.

In your expression, there are 3 term: 3k, 10, and 5n^3

A coefficient is just the number attached to the variable.

In the term 3k, the first one in your expression, the 3 is the coefficient because it is being multiplied by an unknown, k. There is also another term with a variable in your expression: 5n^3. 5 would be the coefficient because it is being multiplied by an unknown, n, multiplied by itself three times

A constant is just a number.

In your expression, 10 is a constant because it doesn't have a variable, so no matter what the other variables are, that term will always stay 10

Hope this helps :)

Find all solutions of the equation in the interval [0, 2π). 2cosθ+ 1= 0

Answers

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:

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.

4x+3(2x-1)-4x i need help

Answers

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

a. Not binomial: the trials are not independent.
b. Not binomial: there are more than two outcomes for each trial.
c. Procedure results in a binomial distribution.
d. Not binomial: there are too many trials.

Answers

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.
