How to determine the graph of the scenario?From the question, we have the following parameters that can be used in our computation:
The empty graph
Also from the question, we have the following equation
f(x) = 80 - 10x
This means that
The variable f is a function of x i.e. f(x)
To plot the graph, we represent the function f(x) on the y-axis
See attachment for the graph of the function
The zeros of the functionThis is the point where the graph crosses the x-axis
This is represented a f(x) = 0
Substitute the known values in the above equation, so, we have the following representation
80 - 10x = 0
Add 10x to both sides
10x = 80
Divide both sides by 10
x = 8

The factors of the polynomial t¹² – r³s¹⁵ is (t⁴ + rs⁵)(t⁸ - rs⁵t⁴+ r²s¹⁰). The correct answer is B.
Describe factor.The definition of a factor is a number that completely divides another number. If adding two whole numbers results in an item, the numbers we are adding are variables of the item since the item can be used to separate them.
By using formula

Step-by-step explanation:
So hi this is saveon and this is how you do the question so first you divide 44.52 by 21 you will get 2.12 feet and that is your answer
It is 2.12 feet wide.
What is rectangle ?
A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.
An equiangular quadrilateral is another name for a rectangle. The reason for this is that a rectangle is a quadrilateral form (4-sided shape) with parallel sides that are equal to one another and four corners with 90o angles. A rectangle can also be referred to as an equiangular quadrilateral because all of the angles are 90 degrees.
Rectangle area = width * height

In addition, the new machine would allow the company to produce one new style of donut, resulting in the sale of 1,000 dozen more donuts each year. The company realizes a contribution margin of $1.20 per dozen donuts sold. The new machine would have a six-year useful life.
Click here to view Exhibit 13B-1 and Exhibit 13B-2, to determine the appropriate discount factor(s) using tables.

1. What would be the total annual cash inflows associated with the new machine for capital budgeting purposes?
2. What discount factor should be used to compute the new machine’s internal rate of return? (Round your answers to 3 decimal places.)
3. What is the new machine’s internal rate of return to the nearest whole percent?
4. In addition to the data given previously, assume that the machine will have a $9,125 salvage value at the end of six
years. Under these conditions, what is the internal rate of return to the nearest whole percent?
As per the question, Total Annual Cash Inflows = 5000, Discount Factor = 3.72 and New Machine's internal rate of return = 16%
Note: The query is not complete and does not contain the necessary information for part 4. It is impossible to fully answer this question without the exhibits stated in the questions. Up until part 3, we will be solving it.
1) The entire annual cash inflows must be calculated for this, and the formula is given below:
Total annual cash inflows are equal to the annual savings from part-time labor plus the additional contribution margin from anticipated sales.
Annual Cash Inflows Total = 3800 + ( 1000 x 1.20)
= 3800 + 1200
= 5000
2. Formula for figuring up the discount percentage:
Discount Factor = New Machine Price/Annual Cash Flow
New machine cost is 18600 USD.
Annual inflow of cash = 5000
Discount Factor is equal to 18600/5000.
Discount Ratio is 3.72.

The linear function in this problem is defined as follows:
y = -328.275x + 3142.5.
The number of CD's sold by year decreases by about 328 million per year. About 3143 million of CD's were sold in 2010.
The estimate for the year of 2019 is of: 188 million CD's.
How to define the linear function?The slope-intercept definition of a linear function is presented as follows:
y = mx + b.
In which the coefficients of the function are defined as follows:
m is the slope, representing the rate of change of the output y relative to the input x.b is the y-intercept, representing the value of the output y when the input x assumes a value of y.Two points of the linear function in this problem are given as follows:
(2, 2485.6), (6, 1172.5)
The slope is given by the change in y divided by the change in x, hence:
m = (1172.5 - 2485.6)/4 = -328.275.
Then:
y = -328.275x + b.
When x = 2, y = 2485.6, hence the intercept b is obtained as follows:
2485.6 = -328.275(2) + b.
b = 2485.6 + 328.275(2)
b = 3142.5.
Hence the function is:
y = -328.275x + 3142.5.
2019 is nine years after 2010, hence the estimate is obtained as follows:
y = -328.275(9) + 3142.5 = 188 million CD's.

this type of bias occurs when researchers fail to choose a representative sample of potential respondents.
Sampling bias, also known as sample selection bias, refers to flaws in research studies that arise when researchers do not appropriately select their subjects.
When a sample is collected in such a way that some members of the intended population have a significantly lower or higher sampling risk than others, sampling bias is reduced.
It yields a skewed sample of a population (or non-human variables) in which not all individuals, but rather cases, were picked in the same way. If this is not considered, the outcomes may be incorrectly attributed to the study problem rather than the sample method.
Sampling bias is often classified as a subset of selection bias, also known as sample selection bias, but some believe it to be a separate type of bias.
The difference between sampling bias and selection bias, though not frequently recognized, is that sampling bias reduces a test's external validity, whereas selection bias only addresses the internal validity of differences or similarities detected in the sample at hand.

A vine called the mile-a-minute weed is known for growing at a very fast rate. It can grow up to 0.5 ft per day. How fast in inches per hour can the mile-a-minute weed grow up to? Show your work using the correct conversion factors.
Answer: 0.25 inches per hour.
Step-by-step explanation:
The mile-a-minute weed can grow up to 0.5 ft per day. To convert this to inches per hour, we need to convert the distance from feet to inches and the time from days to hours.
There are 12 inches in 1 foot, so the mile-a-minute weed can grow up to 0.5 x 12 = <<0.5*12=6>>6 inches per day.
There are 24 hours in 1 day, so the mile-a-minute weed can grow up to 6 / 24 = <<6/24=0.25>>0.25 inches per hour.
Therefore, the mile-a-minute weed can grow up to 0.25 inches per hour.
Here's the complete solution using the correct conversion factors:
1 ft = 12 inches
1 day = 24 hours
0.5 ft/day * (12 inches/1 ft) / (24 hours/1 day) = 0.25 inches/hour
