The volume of water in a tank is modeled by the function y = 1.15x3 – 0.1x2 + 2 where x is the number of minutes after the faucet filling the tank is turned on. What is the y-intercept of the graph, and what does it represent in this context? Choose from the drop-down menus.

Answers

Given:

The volume of water in a tank is modeled by the function

[tex]y=1.15x^3-0.1x^2+2[/tex]

where, x is the number of minutes after the faucet filling the tank is turned on.

To find:

The y-intercept and what does it represent in this context?

Solution:

We have,

[tex]y=1.15x^3-0.1x^2+2[/tex]

Substituting x=0, we get

[tex]y=1.15(0)^3-0.1(0)^2+2[/tex]

[tex]y=0-0+2[/tex]

[tex]y=2[/tex]

Therefore, the y-intercept is 2 and it represents the volume of water in a tank before the faucet filling the tank is turned on.

The volume of water in a tank before the faucet filling the tank is turned on.

10 bags of chips and 8 soda cans cost $15. 5 bags of chips and 5 soda cans cost $8. How much does a bag of chips cost? How much does a can of soda cost?

Answers

I just had the answer but then forgot

Answer:

One bag of chips costs $1.10

One can of soda costs $0.50

Step-by-step explanation:

1. Create a system of equations (b = bags of chips | s = soda)

10b + 8b = 15

5b + 5s = 8

2. Use the Elimination method by multiplying 5b+5s=8 by -2

10b + 8b = 15

-2(5b + 5s = 8)

10b + 8b = 15

- 10b - 10s = -16

(10b and -10b will cancel out, so you will only have s left)

-2s = -1

Divide by 2

Soda = 1/2, or $0.50

3. Plug in S (0.50) into an equation above and get B by itself

5b + 5(0.50) = 8

5b + 2.5 = 8

- 2.5 -2.5

5b = 5.5

Bag of Chips = $1.10

A bag contains 4 yellow balls 5 red balls and 6 blue balls what is the probability of picking a yellow ball

Answers

Answer:

4/15

Step-by-step explanation:

there is a total of 15 balls and there is 4 yellow balls

The probability of picking a yellow ball

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

If the bad contains 4 yellow balls 5 red balls and 6 blue balls, the total outcome will be 15 balls

if a yellow ball is selected, the expected outcome will be 4

Pr(selecting a yellow ball) = 4/15

Hence the probability of picking a yellow ball is 4/15

For every cup of milk, we use 4 cups of flour. Write a linear equation to represent the relationship.

Answers

We can represent these value using variables. Let’s call cups of flour F, and cups of milk M.
So, for every cup of milk we have 4 cups of flour.
We can also wright this as M= 4F
When we have one M (cup of milk) it must be equal to 4F (cups of flour),
For every one M we have 4F.

We can replace M and F with X and Y. They still mean the same thing, we just often see expressions written with X and Y in math.

So,
y=4x

1. Sharon and Geordi both worked hard over the summer. Together they earned a total of $525. Geordi earned $75 more than Sharon.
(a) Write a system of equations for the situation. Use s for the amount Sharon earned and g for the amount Geordi earned.
(b) Graph the equations of the system on the graph provided

Answers

Answer:

s + g = 575

g = 75 + s

g = 325

s = 250

Step-by-step explanation:

Given that :

Total amount earned by Sharon and Geordi = $525

Also, Geordi earned $75 more than Sharon

Let amount earned by Sharon = s

Amount earned by Geordi = g

Equations :

s + g = 575 - - - equation 1

g = 75 + s - - - equation 2

Put g = 75 + s in equation 1

s + 75 + s = 575

2s + 75 = 575

2s = 575 - 75

2s = 500

s = 250

g = 75 + s

g = 75 + 250

g = 325

Submit the work as a file attachment. This means you will complete all work in a word processing document (e.g. Microsoft Word) and attach the file using the Submit Text Step 1: Find Some Physical ArtStart by thinking about all the places in your home, school, town, and general vicinity that you might come across physical art. Maybe there are various sculptures lining the streets in your town or perhaps there is a local museum that you enjoy visiting to admire the physical art. Or maybe you have various works of physical art right in your own home!Start exploring the physical art around you and choose a piece of physical art that you will use as inspiration for your digital art creation. Visit this piece of physical art with your camera in hand and take as many photographs as you possibly can from all angles and directions. You may even find it useful to bring a small notepad to jot down any observations that you make while viewing this art in person so it remains fresh in your memory.After you have fully locked all the details of this physical art piece into your mind (and into your camera/camera phone), you are ready to move on to the next step!Step 2: Research Software OptionsTake some time to explore online and learn about the various ways that digital art is created. What types of programs are used? Are there free websites or apps that might be helpful? What skills or tools will you need to call upon to create this digital art masterpiece?Make a list of the possible software tools and options that you find in your research that are available to help you create your digital art piece. Identify the program(s) or tool(s) that you plan to use for this lab.Step 3: Make a PlanNext, map out a loose plan for your digital art. This can be as simple as typing up some notes in a word processing document using bullet points to create a plan of action for how you will approach this digital creation.Some questions to consider:How will you capture the essence of the physical art digitally?What are some key aspects that you need to pay attention to?What components of the physical art are you apprehensive to re-create digitally?Are there any aspects of the physical art that you want to change when you re-create it digitally?It is important to note that while you should be able to recognize and see the resemblance between the physical art piece that you choose and your digital re-creation, you do have some creative ownership in this processafter all, youre the artist! That means that you have the creative freedom to shift or slightly change some aspects of the physical art that you want to while re-creating it digitally in order to truly make it your own!After exploring the possible programs or tools available to you to create your digital art and mapping out a plan, it is time to get started!Step 4: Create!Using whatever program or tools you decided on, jump right in to re-creating your physical piece of art in a digital medium.While you are creating your digital art, keep in mind that you will be submitting the photos of your physical piece of art along with your digital re-creation, and the resemblance should be evident. It is certainly okay for various details to be different based on your creative ideas and instincts, but make sure that the most defining and dominant features of the original piece of physical art are evident in your digital re-creation.Step 5: ReflectThe final piece in this lab is to compose a brief reflection/explanation of your digital re-creation. There are no specific questions that you need to answer in this reflection; however, you should aim to simply explain the components and features of your digital art piece that you are proud of and want recognized, as well as how these features relate to the physical piece.You can also discuss your experience with recreating a piece of physical art digitally and the challenges that you faced as well as the aspects of the assignment that you enjoyed.Your reflection should be no longer than one page; one to two paragraphs is sufficient.You will submit the photographs of the physical art piece you chose, your list of digital creation tools, your map or plan for your digital work of art, your actual digital re-creation, and your reflection all together.(i wanna do it on something with art) I did a chocolate lab.
