Un aserradero adquiere maquinaria y equipo para el corte de madera, que va perdiendo valor conforme transcurren los años, hasta que su valor contable es cero, como indica la gráfica de la función D(x)=(-x^3+2x^2+20x+20)/(x^2+4x+4) que modela esta depreciación en el eje y cada unidad son 20 000 pesos y en el eje x cada unidad es de 3 años.
a) ¿Cuál es el valor inicial del equipo y herramienta? ¿cuánto se ha depreciado al cabo de 12 años?

b) ¿existe un modelo lineal que aproxime los mismos valores que la función D(x)?

c) ¿En cuánto difieren los valores de ambas funciones al cabo de 9 años?

Marley loves to draw and color. She bought 6 boxes of crayons. There are 8 crayons in each box. What is the total number of crayons Marley bought? What operation did you use to find your answer? Be sure to write your answer in a complete sentence.

Answers

Answer:

48 crayons

Step-by-step explanation:

There are 6 boxes total, each with 8 crayons in them. Notice that if you would count all the crayons, you would add 8 to the total number of crayons each time you counted a box. There are 6 boxes, so that would be equivalent to adding 8 a total of six times. You would use multiplication: 6 x 8 which is 48.

Answers

Answer:

[tex]x^2-\dfrac{9}{2}x-9=0[/tex]

Step-by-step explanation:

The solutions of a quadratic equation are :

x = -3/2 and x = 6

or we can write it as :

[tex]x+\dfrac{3}{2}=0\ and\ x-6=0\\\\(x+\dfrac{3}{2})(x-6)=0[/tex]

Multiplying both values,

[tex](x+\dfrac{3}{2})(x-6)=0\\\\x^2-6x+\dfrac{3}{2}x-9=0\\\\x^2-\dfrac{9}{2}x-9=0[/tex]

Hence, the required quadratic equation is [tex]x^2-\dfrac{9}{2}x-9=0[/tex].

Andre sets up a rain gauge to measure rainfall in his backyard. On Tuesday, it rains off and on all day, use the graph to determine how much total rain fell on Tuesday

Answers

The total amount of rainfall is an illustration of the sum operator

The total amount of rainfall that fell on Tuesday is 35 mm

How to determine the total amount of rainfall?

From the graph (see attachment), we have the following function values

f(10) = 2

f(11) = 3

f(12) = 2

f(1) = 4

f(2) = 6

f(3) = 8

f(4) = 10

f(5) = 0

Add up the function values to determine thet total amount of rainfall

Total = 2 + 3 +2 + 4 + 6 + 8 + 10 + 0

Evaluate the sum

Total = 35

Hence, the total amount of rainfall that fell on Tuesday is 35 mm

The Company has spent $5 million in research and development over the past 12 months developing cutting-edge battery technology which will be incorporated into the electric vehicle market. INT now need to choose between the following three options for bringing the product to market. These options are: Option 1: Manufacturing the product in-house and selling directly to the market Option 2: Licensing another company to manufacture and sell the product in return for a royalty Option 3: Sell the patent rights outright to the company mentioned in option 2 Your task Your manager, INTs CFO, Mr Barry Smith, has asked you to evaluate the three different options and draft a memo to the Board of Directors providing recommendations on the alternatives, along with supporting analyses. Mr Smith has outlined the following three (3) areas you need to cover in your memo: a) Analyse base case figures for the three options and using NPV as the investment decision rule; b) Provide recommendations based on the base-case analyses; c) Provide recommendations on further analyses and discuss factors that should be considered prior to making a final decision on the three options (Note. You do NOT have to undertake any further financial analyses). Further details for the various options are as follows: Option 1: Manufacturing the product in-house and selling directly to the market Three months ago, INT paid an external consultant $1.5 million for a production plan and demand analysis. The consultant recommended producing and selling the product for five years only as technological innovation will likely render the market too competitive to be profitable enough after that time. Sales of the product are estimated as follows: In the first year, it is estimated that the product will be sold for $45,000 per unit. However, the price will drop in the following three years to $40,000 per unit and fall again to $36,000 per unit in the final year of the project, reflecting the effects of anticipated competition and improving technology Year Estimated sales volume (units) 1 5,200 2 4,600 3 4,200 4 3,800 5 3,600In the first year, it is estimated that the product will be sold for $45,000 per unit. However, the price will drop in the following three years to $40,000 per unit and fall again to $36,000 per unit in the final year of the project, reflecting the effects of anticipated competition and improving technologyin the market. Variable production costs are estimated to be $29,000 per unit for the entire life of the project. Fixed production costs (excluding depreciation) are predicted to be $3 million per year and marketing costs will be $1.6 million per year. Production will take place in factory space the company owns and currently rents to another business for $2.5 million per year. Equipment costing $87 million will have to be purchased. This equipment will be depreciated for tax purposes using the prime cost method at a rate of 10% per annum. At the end of the project, the company expects to be able to sell the equipment for $37 million. Investment in net working capital will also be required. It is estimated that accounts receivable will be 30% of sales, while inventory and accounts payable will each be 25% of variable and fixed production costs (excluding depreciation). This investment is required from the beginning of the project because credit sales, inventory stocks and purchases on trade credit will begin building up immediately. All accounts receivable will be collected, suppliers paid and inventories sold by the end of the project, thus the investment in net working capital will be returned at that point.

Rework the photo memoir essay to incorporate the historically significant information into a new essay that argues a point based on the graphic and textual sources you gathered. Cite the sources both implicitly and explicitly within your essay.Here is the memoir I wroteIt is what it is. Though its a cliche phrase, this is the photograph that Ive selected to discuss. It may sound trite, this quote possesses a deeper meaning. When life seems to be out of control, it causes me to feel overwhelmed. Its an instinct that I immediately want to take matters into my own hands, but in some situations, this is not feasible. This quote represents a deeper meaning that I cannot control things that are beyond me. Furthermore, the topic of discussion will revolve around It Is What It Is. Its hard to deny that when situations in our life don't go our way or even how we had planned we don't get upset. In my case, this situation can ruin my day. For example, before a ski race I used to have an expectation for myself, and I would give my best performance on the hill. Sometimes I would come up short, and this is what used to upset me. Although at the time I didn't realize that I did everything in my control to win, so at the end of the day I was racing myself. How does this tie back to It Is What It Is? Well, it seems that increasingly often you hear the phrase, It is what it is. I was taking the phrase to mean, Its not this and its not that; its something more subtle that I dont have a name for, and Im ok with that. This actively demonstrates that you're ok with things not going your way, and this can lead to better self-development. By letting things hang in an uncategorized state in their mind they may slowly come to a richer, more nuanced understanding of it, which may lead to a new insight or invention.Although there are benefits to It Is What It Is, the phrase comes with downfalls. For example, when you do have the power to change something going wrong, and you use the phrase it may come more across as giving up. Another way of saying this would be if somebody needs your help, and you have the power to help them, although you decide not to because you think the outcome is inevitable. Even though there is this downfall it does not ruin the phrase. You just have to use it at the correct time. For instance, the correct time to use this phrase would be when something is out of your control, and you are struggling to cope with it. The phrase wasn't meant to give up, it's less meant to deal with it. This phrase oddly enough has helped me cope with things that are out of my control. To sum up, everything that has been stated so far It Is What It Is is an expression used to characterize a frustrating or challenging situation that a person believes cannot be changed and must just be accepted. In saying this it demonstrates more regard for I won't let something out of my control affect me.Help me understand what to do? A fossil contains 1/16 of the carbon -14 it began with.
