Problem 2.2
A company bought a milling machine for $ 100,000. The company intends to use the machine for the next 5 years. The machine is expected to save the company $ 42,000 during the first year of operation. Thereafter annual savings are expected to decrease 3% each year due to maintenance costs. Assuming 4,000 hours of operation per year and that the machine will have no “Salvage Value” at the end of the 5 years, determine the equivalent savings per hour of operation at 14% compounded annually.

Quadrilateral ABCD is a parallelogram. What is BC?
Try to explain if you can! Thank you
The side [tex]BC[/tex] represents the base of the parallelogram.
How to analyze a parallelogramsIn this question we must analyze a particular quadrilateral based on their inherent characteristics. Quadrilaterals are figures formed by four sides and four internal angles so that the sum of the latter equals 360°.
Parallelograms are quadrilaterals with two pairs of parallel sides of equal lengths, each pair is not parallel to its counterpart. Like any quatrillateral, it can be represented in terms of its base and height.
According to the image given, the side [tex]BC[/tex] and, likewise, the side [tex]AD[/tex] represent the base of the parallelogram. In a nutshell, the side [tex]BC[/tex] represents the base of the parallelogram. [tex]\blacksquare[/tex]

hope that helps
Hey there!
These are the 2 kinds of sequences:
Arithmetic sequence. This is where we use addition/subtraction in order to get the next term.Geometric sequence. This is where we use multiplication/division in order to get the next term.Let's check the given sequence:
15, 12, 9, 6...
Do we use addition, subtraction, multiplication or division?
Well, we definitely do not multiply or divide anything here, so we have an arithmetic sequence.
Do we use addition or subtraction?
Well, let's take another look at our sequence.
15, 12, 9, 6...
As you can see, we use subtraction in order to get the next term.

Find the slope and the y-intercept of the line.
3x+2y=7
Write your answers in simplest form.
Step-by-step explanation:
Make 3x+2y=7 to slope intercept form. y = mx + b
So subtract 3x from both sides to get 2y= -3x + 7
Then divide by 2 on both sides to get y = -3x/2 + 7/2
The slope is -3/2 and the y-intercept is 7/2
This data set represents the number of cups of flour used in different recipes. What is the mean of this data set? {1/2, 1/3, 2/3, 1 1/2} Enter your answer as a fraction in simplest form in the box.
Using it's concept, it is found that the mean of the data-set is of [tex]\frac{3}{4}[/tex].
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
In this problem, the 4 observations are given by:
[tex]\left{\frac{1}{2}, \frac{1}{3}, \frac{2}{3}, 1\frac{1}{2} = 1 + \frac{1}{2} = \frac{3}{2}\right}[/tex]
Hence, the mean is given as follows:
[tex]M = \frac{\frac{1}{2} + \frac{1}{3} + \frac{2}{3} + \frac{3}{2}}{4} = \frac{\frac{3 + 2 + 4 + 9}{6}}{4} = \frac{18}{24} = \frac{3}{4}[/tex]
The mean of the data-set is of [tex]\frac{3}{4}[/tex].

What is the equation in point slope form for a linear function with a slope of m= -4 that passes through the pot
(2, - 7)?
Answer:
Step-by-step explanation:
m = -4 ; (x₁ , y₁) = (2, -7)
Point slope form: y - y₁ = m(x - x₁)
y - [-7] = (-4)(x - 2)
y + 7 =(-4)(x - 2)
