What is the twentieth term of the arithmetic sequence described by the
equation an= 3n - 10?

Answers

Answer:

The twentieth term is 50.

Step-by-step explanation:

The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:

a1 = 3*1 - 10

a1 = -7

Therefore to find the twentieth term we need to make n equal to 20. This is done below:

a20 = 3*20 - 10

a20 = 60 - 10

a20 = 50

The twentieth term is 50.

Calculate the volume of the figure. Use 3.14 for π.

Enter your answer as the number of m3, rounded to the nearest hundredth if necessary, like this: 42.53

Answers

Answer:

[tex]586.13\,\,m^3[/tex]

Step-by-step explanation:

Given: Figure

To find: Volume of the figure

Solution:

The given figure is composed of two shapes:cylinder and hemisphere

Radius of cylinder = 4 m

Height of cylinder = 9 m

Volume of cylinder = [tex]\pi (radius)^2height=\pi (4)^2(9)=3.14(16)(9)=452.16\,\,m^3[/tex]

Volume of hemisphere = [tex]\frac{2}{3}\pi (radius)^3=\frac{2}{3}(3.14)(4)^3= \frac{2}{3}(3.14)(64)=133.9733\,\,m^3[/tex]

So,

total volume of the figure = Volume of cylinder + Volume of hemisphere = 452.16 + 133.97 =586.1333 [tex]m^3[/tex]

If 586.1333 is rounded to the nearest hundredth, it becomes 586.13  [tex]m^3[/tex]

Answer:

586.13 is the answer

Show the Euler-Descartes formula holds for the Great Pyramid of Cheops

Answers

Answer:

For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula

Step-by-step explanation:

The great pyramid of Cheops is a square based pyramid therefore we have;

V + F = E + 2

Where:

V = Vertices

F = Faces

E = Edges

Hence, we have for a square pyramid;

V = 5 vertices (One at the peak, and four  at the base edges)

F = 5 faces (The four lateral or side faces and the base)

E = 8 edges ( The four lateral edges and the four base edges)

Hence;

5 + 5 = 8 + 2 which proves Euler-Descartes formula.

Solve the following equation:

​ 12(b+2)+3b=−1

​Enter your answer as a fraction.

Answers

Answer: -5/3

Step-by-step explanation:

12(b + 2) + 3b = -1

12b + 24 + 3b = -1

15b + 24 = -1

15b = -1-24

b = -25/15 = -5/3

The solution to the equation 12(b+2) + 3b = -1 is b = -5/3.

What is the solution to the given equation?

Given the equation in the question:

12( b + 2 ) + 3b = -1

To solve the equation 12( b + 2 ) + 3b = -1, first apply the distributive property.

Distribute the 12 across the terms inside the parentheses:

12( b + 2 ) + 3b = -1

12×b + 12×2 + 3b = -1

Simplifying, we get:

12b + 24 + 3b = -1

Collect and combine the like terms on the left side of the equation:

12b + 3b + 24 = -1

15b + 24 = -1

Subtract 24 from both sides of the equation:

15b + 24 - 24 = -1 - 24

15b = -1 - 24

15b = -25

Divide both sides by 15:

b = -25/15

Simplify

b = -5/3

Therefore, the value of b is -5/3.

2. How much paint (in square meters) do you need to paint the pool?
3. How much will it cost to paint the pool?
4. How much water will the pool hold?

Answers

Answer:

Step-by-step explanation:

I'm going to assume you meant to put numbers in the question, but I will answer in terms of x, y, and z, for length, width, and depth, respectively.

1. You need to pain 4 walls as well as the floor, so 5 surfaces total.

2. This question is asking for the surface area of the pool. There is 1 floor, 2 long walls and 2 wide walls.

         Surface Area = 2 (wide) + 2 (long) + 1 (floor)

                                = 2(x*z) + 2(y*z) + 1(x*y)

         *remember to answer in meters squared*

3. Total Cost = (surface area) * (cost per square meter)

         *remember this is in dollars*

4. This question is asking about the volume of the pool:
