Seattle’s factory is the company’s newest. It was constructed with sustainable building techniques and materials, so its cost structure has been affected in several ways. The Seattle plant uses a mix of solar power (not very reliable with so many clouds), thermal power, and wind. It has an array of batteries, so at the beginning of each production day, there is “free” stored energy that can produce up to 8,000 units. Of course, energy is just one factor of the cost of production, but it is significant.
The cost function for the Seattle factory is given by the following piecewise function. That is, C(x)is the cost function, where x is the number of units produced. The plant’s maximum capacity is 42,000 units per day.
[tex]C(x)=\left \{ {{0.35 if x \leq 8,000} \atop {0.75 if 8,000\ \textless \ x\leq 20,000}} \right \atop0.83-(\frac{x}{200,000} ) if 20,000\ \textless \ x\leq 42,000[/tex]
A) Sketch a graph to model Seattle’s cost structure over the domain [0, 42000]. Be sure to label the axes and any endpoints where the graph breaks.
B) Describe the function over each part of its domain. State whether it is constant, increasing, or decreasing, and state the slope over each part.
Answer:
Natural Capitalism as an idea and thesis for a book emerged in 1994, the year after the
publication of The Ecology of Commerce. After meeting with and speaking to different
business, government, and academic institutions in the aftermath of the book's
publication, it became clear to Hawken that industry and government needed an overall
biological and social framework within which the transformation of commerce could be
accomplished and practiced. To that end, articles and papers were written that became the
basis of a book about natural capitalism. A key element of this theory was the idea that
the economy was shifting from an emphasis on human productivity to a radical increase
in resource productivity. This shift would provide more meaningful family-wage jobs, a
better worldwide standard of living to those in need, and a dramatic reduction of
humankind's impact upon the environment. So while the context for Natural Capitalism
existed in a theoretical framework, the exposition did not.
Contemporaneously, Amory and Hunter Lovins were coming to the same conclusion: that
a shared framework was needed that could harness the talent of business to solve the
world's deepest environmental and social problems. Both were writing Factor Four:
Doubling Wealth, Halving Resource Use for publication in Germany in 1995. The senior
author of Factor Four, Ernst von Weizsäcker, among Europe's top innovators in
environmental policy, had teamed up with the Lovinses to pool the experience of their
respective nonprofit research centers—Wuppertal Institute in Germany and Rocky
Mountain Institute (RMI) in Colorado. The three authors had assembled fifty case studies
of at least quadrupled resource productivity to detail how, across whole economies,
people could live twice as well but use half as much material and energy. Factor Four
showed that such striking gains in resource efficiency could be profitable, and that
obstacles to their implementation could be hurdled by combining innovations in business
practice and in public policy.
Both Factor Four and The Ecology of Commerce urged the private sector to move to the
vanguard of environmental solutions. Factor Four described a creative policy framework
that could foster fair and open competition in achieving that success. The Ecology of
Commerce suggested techniques that when combined with business's unique strengths
could enable it to meet this challenge successfully.
Hunter Lovins sent a draft of Factor Four to Paul Hawken in early 1995. He saw that it
was the exposition that natural capitalism needed if it were to make its theoretical claims
credible and demonstrable. The ideas not only meshed, they were absolutely
complementary. We agreed to work together toward one book, under the title of Natural
Capitalism, that would contain both theory and practice. After the work began, we
discovered it wasn't that simple. Factor Four was anecdotal, Europe-oriented (by 1997 it
had also been published in England after being a German bestseller for nearly two years),
and written more for policy and environmental activists than for business practitioners. It
needed not adaptation but complete rewriting. Further, the examples offered concentrated
mainly on efficiency and did not take fully into account the need for the restoration of
natural capital nor for several other important elements of natural capitalism that go far
The graph shows the cost (C) of shipping a package based on its mass in pounds (p)
Enter an equation to represent the cost (C) of shipping a package based on its mass in pounds (p).
Answer:
C = 4p
Step-by-step explanation:
Because it starts at 0 pounds costs 0 dollars, we know it starts at the origin and has no y-intercept. Because it rises up 20 dollars for every 5 pounds, we can use rise/run to do 20/5 to get an increase of 4 dollars per pound.

A school principal wants to buy some book cases for the school library. She can choose between two types of book case. Type A costs $10 and it requires 0.6 m2 of floor space and holds 1.2 m3 of books. The maximum floor space available is 7.2 m2 and the budget is $140 (but the school would prefer to spend less). What number and type of bookcases should the principal buy to get the largest possible storage space for books?
The principal should buy 8 of type A and 3 of type B to get the largest possible storage space for books
How to determine the number and type of book cases?Let x represent type A and y represent type B,
So, we have the following table:
x y Available
Floor space 0.6 0.8 7.2
Budget 10 20 140
Book hold 0.8 1.2
Using the above table, we have the following linear model
Objective function Min Z = 0.8x + 1.2y
Subject to
0.6x + 0.8y ≤ 7.2
10x + 20y ≤ 140
x, y > 0
Using a graph, the solution to the above system of inequalities is:
(x,y) = (8,3)
Hence, the principal should buy 8 of type A and 3 of type B to get the largest possible storage space for books

Determine the cost of 2 years at a community college or 4 years at a state college (in your home state or out of state). explain the cost of your chosen college in 4-6 sentences. remember, the cost of college includes: tuition room and board books/supplies gas spending money
The explanation of the cost of a sample college would be the fact that fees such as tuition would be paid, other essentials that are necessary for the learning and development of the student such as books are also needed.

[tex]2 \cos(2x - \frac{\pi}{3} ) = 1[/tex]
[tex] \cos(2x - \frac{\pi}{3} ) = \frac{1}{2} [/tex]
Take the inverse cosine of both sides
[tex]2x - \frac{\pi}{3} = \cos {}^{ - 1} ( \frac{1}{2} ) [/tex]
[tex]2x - \frac{\pi}{3} = \frac{\pi}{3} + 2\pi(n)[/tex]

Find the quotient of 2 3/5 ÷ 1 2/5 Give your answer as a mixed number in its simplest form.
The quotient of 2 3 / 5 ÷ 1 2 / 5 as a mixed fraction is 1 6 / 7
What is quotient?Quotient is the answer obtained when we divide one number by another. Therefore,
2 3 / 5 ÷ 1 2 / 5
let's convert the mixed fraction to improper fractions.
2 3 / 5 = 13 / 5
1 2 / 5 = 7 / 5
Therefore,

what’s the area and the perimeter and of the triangle?
Answer:
Area = 3.3998
Perimeter = 2.9
Step-by-step explanation:
A method for calculating the area of a triangle when you know the lengths of all three sides.
Let a,b,c be the lengths of the sides of a triangle. The area is given by:
Area = √ p ( p − a ) ( p − b ) ( p − c )
where p is half the perimeter, or
a + b + c / 2
p = 1.7 + 1.7 + 2.4 / 2 = 5.8 / 2 = 2.9
a = Area = 3.3998

Maria and Bridgette both belong to the same public pool and attend swim classes with a coach. Maria pays $105 for her season pass and 6 swim classes. Bridgette pays $135 for her season pass and 9 swim classes. What is an equation for the cost of a season pass and swim classes as a function of the number of swim classes attended? Explain what each variable represents and identify the initial value and the rate of change. Show your work.
Answer:
T = 10s + 45Step-by-step explanation:
Since both Maria and Bridgette belong to the same public pool they pay same rate for season pass and each class.
Let the season pass be y and swim class cost be x.
Then according to given we have the following equations
y + 6x = 105y + 9x = 135Solve the system by elimination, subtract the equations
y + 9x - y - 6x = 135 - 1053x = 30x = 10Find y
y + 6*10 = 105y = 105 - 60y = 45The initial value is 45 and rate of change is 10.
The equation for the total cost would be
T = 10s + 45, where T - total cost, s - number of swim classes
