the first part of the problem asks them to calculate the work done on the gas when the gas goes from the initial state to the final state shown. here is part of their dialogue: nora: the gas is compressed because the volume decreases. that means that there is work done on the gas, and the work is positive. bob: ok. that's right because we're using the first law with q w. we need to use that area thing to find the work. nora: yeah. we want the area under the line between the dots. bob: that line shows the process, right? nora: yup, that's the one. so the area is one-half times base times height. it's the area of that triangle. bob: but you have to add the area of that skinny rectangle below it, don't you? nora: i don't think so. that bottom dot for the final state tells you where the bottom of the area is. bob: why don't we ever agree? tell you what. we'll each try our own way and let webassign tell us who's right. nora: hmmm... i hope i get the big, green check mark!

Find the degree measure of each interior angle of quadrilateral PQRS.
Note: Figure not to scale.
angle s= 2yº
angle p= 3yº
angle q= 4y°
angle r= y°
Answers
S=72, P=108, Q=144, and R=36 are the degree measures for each quadrilateral angel.
Calculating the angles:Since the sum of all angles is 360.
∠S+∠P+∠Q+∠R=360
2y+3y+4y+y=360
10y=360
y=36.
Hence, we get ∠S=72, ∠P=108, ∠Q=144 and ∠R=36.
Name some of the properties of the quadrilateral and explain what it is?A polygon with four sides, four vertices, and four angles is called a closed quadrilateral. It is made by joining four non-collinear points together. In all cases, the inner angles of quadrilaterals add up to 360 degrees.
Do the interior angles of all quadrilaterals add up to 360?The fact that the sum of the interior angles is always equal to 360 degrees is a property shared by all of the above four-sided shapes. Each interior angle of a regular quadrilateral, such as a square, will be equal to: 90 degrees is 360/4.
Are there four equal angles in every quadrilateral?They split in two directions. There are both regular and irregular quadrilaterals. The diagonals of a regular quadrilateral must cross each other and have four equal sides and angles. The only quadrilateral that meets all of these requirements is square

1. You are the manager of a small store that specializes in hats, sunglasses, and other accessories. You are considering a sales promotion of a new line of hats and sunglasses. You will offer the sunglasses only to those who purchase two or more hats, so you will sell at least twice as many hats as pairs of sunglasses. Moreover, your supplier tells you that, due to seasonal demand, your order of sunglasses cannot exceed 100 pairs. To ensure that the sale items fill out the large display you have set aside, you estimate that you should order at least 210 items in all. Assume that you will lose $3 on every hat and $2 on every pair of sunglasses sold. Given the constraints above, how many hats and pairs of sunglasses should you order to lose the least amount of money in the sales promotion? [Using Graphic method]
Answers
Graphical techniques are widely used to assess whether the data support the fractionation of a single source or the mixture of two putative sources.
For 210 items in total there will be 140 number of hats and 70 number of pairs of sunglasses.
What is meant by Graphic method?To determine if the data support the mixing of two potential sources or the fractionation of a single source, graphical approaches are frequently used.
To better interpret their data, researchers now employ a variety of graphical tools, including scatterplots, box plots, and histograms. Graphs are excellent for illustrating trends, patterns, and correlations between variables as well as for displaying and summarizing vast volumes of numerical data.
We generate a graph for each equation in order to solve systems of equations or simultaneous equations graphically. Then, we search for the intersection of the two graphs. The system of equations would have a solution at the coordinates of the point of intersection.
Let x be the number of hats and y be the number of pairs of sunglasses.
The constraints exists:
2y = x (because for every 2 hats sold, 1 pair of sunglasses is sold)
y <= 100 (because the supplier can only provide 100 pairs of sunglasses)
x + y >= 210 (because you want to sell at least 210 items in total)
x, y >= 0 (because the number of items sold cannot be negative)
Lose in every hat is $3 and in Pair of Sunglasses is $ 2
Total loss in promotion or cost of promotion is
3x + 2y
For least purchase,
x + y = 210
⇒ x + x/2 = 210
⇒3x/2 = 210
⇒ x =140
y = 140/2 = 70
So, for 210 items in total there will be 140 number of hats and 70 number of pairs of sunglasses.

An absolute maximum point is where the function reaches its highest value.
What is the difference between absolute maximum and absolute minimum?A function may have more than one location (x values) or point (ordered pairs) where these values occur, but there can be only one absolute minimum value and one absolute maximum value (in a given closed interval).
A point where the function achieves its highest value is known as an absolute maximum point. Similar to this, an absolute minimum point is the location at which the function's maximum value is obtained.
Minimum refers to the bare minimum that can be done. For instance, if anything requires seven dollars as the minimum payment, you cannot make a payment of six or less (you must pay at least seven). More than the bare minimum is acceptable, but not less. Maximum refers to the greatest quantity of anything.

Step-by-step explanation:
x + y = 3/4
x -y = 5/2
2x = 13/4 3/4 + 5/2 = 3/4 + 10/4 = 13/4 Next divide both sides by 2
[tex]\frac{2x}{2}[/tex] = [tex]\frac{\frac{13}{4} }{2}[/tex] [tex]\frac{13}{4}[/tex] ÷[tex]\frac{2}{1}[/tex] = [tex]\frac{13}{4}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{13}{8}[/tex]

13/8 + y = 3/4 Subtract 13/8 from both sides
y = -7/8 3/4 - 13/8 = 6/8 - 13/8 = -7/8
Check:
substitute x = 13/8 and y = -7/8 back into the original two equations to see if the equations ae true

find the fixed point of the function f. [a fixed point of a function f is a real number c such that f(c)
Answers
The fixed point of the function f(x) = x^2 + 1 is c = 0.
f(x) = x^2 + 1
c = 0
To find the fixed point of the function f, we can set the equation f(x) = x^2 + 1 equal to x, since the fixed point is when f(x) is equal to x.
Therefore, we can solve for x by setting x^2 + 1 = x. Re-arranging the equation, we get x^2 - x + 1 = 0.
Using the quadratic formula, x = (-(-1) ± √(1 - 4(1)(1))/(2(1))
Simplifying this expression, x = (-1 ± √3)/2.
Since we are looking for a real number, we can eliminate the negative solution and set x = (1 + √3)/2.
Therefore, the fixed point of the function f is c = 0.
The fixed point of the function f(x) = x^2 + 1 is c = 0.

Answers
Answer:
Perimeter = 8π cm
Area = (32π - 64) cm²
Step-by-step explanation:
ABCD is a square.
Therefore:
AB = BC = CD = DA = 8 cmArea = 8 × 8 = 64 cm²PerimeterThe perimeter of the shaded part is the sum of two congruent quarter circles, i.e. half the length of the circumference.
The arcs AC are quarter circles of a circle with radius 8 cm.
Therefore the perimeter of the shaded area is:
[tex]\implies \sf Perimeter=Half\;circumference=\dfrac{1}{2} \cdot 2\pi r=\pi r=8\pi\;cm[/tex]
AreaTo find the area of the shaded area, subtract the two unshaded areas from the area of the square.
As the two unshaded areas are congruent we only need to find the area of one unshaded area.
The area of one unshaded area is the area of the square minus the area of the sector ADC (which is a quarter of a circle with radius 8 cm).
[tex]\begin{aligned}\implies \textsf{Area of one unshaded area}&=\textsf{Area of square}-\textsf{Area of $\frac{1}{4}$ circle}\\&=64-\dfrac{1}{4} \pi r^2\\&=64-\dfrac{1}{4} \pi \cdot 8^2\\&=64-\dfrac{1}{4} \pi \cdot 64\\&=(64-16 \pi)\; \sf cm^2\end{aligned}[/tex]
Now we have found the area of one unshaded area, to calculate the area of the shaded area simply subtract two unshaded areas from the area of the square:
[tex]\begin{aligned}\implies \textsf{Shaded area}&=64-2(64-16\pi)\\&=64-128+32\pi\\&=(32\pi-64)\; \sf cm^2 \end{aligned}[/tex]
