There are a very large amount of possible solutions. A few examples.
10 + 10 + 10 + 10 + 10 + 1 + 1 = 52.
10 + 10 + 10 + 10 + (12 ones here) = 52.
10 + 10 + 10 + (22 ones here) = 52.
10 + 10 + (32 ones here) = 52
10 + (42 ones here) = 52
(52 ones here) = 52

I'm fairly sure those are all possible ways.

The table lists the results from a survey (of questionable accuracy) of adults and how much they spend on a night out.
daser333 [38]
You are going to make a graph. The x-axis will represent age while the y-axis represents the amount of money spent on a night out. Graph the ordered pairs, making a scatter plot. Once you have all of the points on the graph, answer the question by saying something like "the older someone is, the less money they spend on a night out" but make sure it's accurate. (:

Can someone explain how to do numbers 41, 44, and 47 and show all work please?
pantera1 [17]
41. Degree 3 = x^3 (maximum power in the equation)

Zeros: -1, 1, 3

(x-1)(x+1)(x-3)=f(x) <--- expand as necessary

44. Zeros: -4, 0, 2

(x+4)x(x-2)= f(x) <--- expand as necessary

47. Multiplicity is how many times a particular number is 0 for a given function.

(x+1)(x-1)^3(x-2)^3 <-- not too sure about this one, google definition of multiplicity?

Hope I helped :)

A new furnace for your small factory will cost $29,000 and a year to install, will require ongoing maintenance expenditures of $
Neporo4naja [7]

Answer:

Net present value is $61,058.

Step-by-step explanation:

Net present value is the difference between present value of cash inflows and the present value cash outflows over the period of time. NPV method is used in capital budgeting to analyze profitability of the project.

Less: initial cost is $29,000

Add: Year 1: Cost saving due to new furnace is $5,600 (2,800 oil gallons * $ 2 per gallon)

Year 2: Cost saving due to new furnace is $7,000 (2,800 oil gallons * $ 2.50 per gallon)

Year 3- 20: Cost saving due to new furnace is $8,400 (2,800 oil gallons * $ 3 per gallon)

Less : Maintenance expenditure is $1,200

The furnace will benefit for 20 years and the price per gallon will increase by $0.50 year.

The annuity factor is applied at discount factor of 6% and then present value of each cash inflow and outflow is calculated. The net present value is $61,058.
