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

V = 2,560 m^3

Step-by-step explanation:

The formula for the volume of a pyramid is...

[tex]V=\frac{1}{3}Bh[/tex]

B is the area of the base, which in this case is a rectangle. We need to find the area of the rectangle to plug in for B.

The formula for the area of a rectangle is...

[tex]l*w[/tex]

We can plug in the numbers.

[tex]16*24[/tex]

= 384

Now that we have B, we can plug that into the volume formula along with the height.

[tex]V=\frac{1}{3}(384*20)[/tex]

[tex]V=\frac{1}{3}*7,680[/tex]

V = 2,560 m^3

An in-ground swimming pool is meters long, meters wide, and meters deep. The water-resistant paint needed for the pool costs $ per square meter. Step by step.
1. How many sides of the pool do you have to paint?
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:

         Volume = x*y*z

The square of a number can never be negative and as such a² ≠ - 25.

Proof of this is that the √-25 = 5i  (aka an imaginary number).
