1. Answer Following Questions, Show work, clear hand writing,
thank you
a. Set up (i.e. DO NOT SOLVE) an integral to find the volume of
the solid obtained when the given region is rotated about the given
axis. The region bounded by y = 2x^2 and y = 2x^3 about the line x
= −1
b. get the general antiderivative of f(x) = (x^2)*(e^−x)
c. Find the length of the polar curve r = 2cosθ

There are one positive charge +3Q and one negative charge −Q
which are fixed on the x-axis with coordinate (−d,0) and (d,0)
respectively. We would like to place a third one, carrying +2Q, at
some place such that the net electric force on it is zero.
I said that the third charge should be placed to the right of
the negative charge (-Q) so that the +3Q and -Q charges are
canceling out.
k(3Q)(Q)/(x^2) = k(2Q)(Q)/(x-2d)^2

The (total) cost function is given by C = 60 +
80q – 15q2 + 2q3,
where q is the quantity produced by the firm.
Find the break-even point (q and AC).
Find the shut-down point (q and AVC).
Draw a graph to illustrate AC, AVC, and
MC functions for quantities Q on the interval
between 1 and 10. Make sure you show (put the numbers there) where
exactly the MC curve intercepts AVC and
AC curves.
If the price...

Many of the world's largest companies, such as Toyota offshore
their manufacturing and /or assembly processes. 1- where
are its products or product components made? why did the company
choose to manufacture its products there? 2- has the company
experienced any negative reactions to outsourcing? please if I can
get at least three paragraph for this. this have to be own
words. please thank you. Write THREE paragraphs about your
topic. The first paragraph should give a brief history and...

Can someone please clarify for me the following... I am very
confused in chemistry when it comes to orbitals and what exactly
they mean and represent. Like let's take a random element.. for
example Fe. Iron has an electron configuration of
1s22s22p63s23p64s23d6,
but what exactly does that mean? Please answer the following to
help me understand:
1. When I read
1s22s22p63s23p64s23d6,
does this represent a single electron in Fe or does it represent
all of them at once?
2. If...

Could you please show me how to set up and calculate the
matrices for the following problem. They need to be done using
matrix multiplication. Could you please explain each of the steps
in detail because I am having trouble setting up the matrices. I
will leave feedback for you if you provide a quality answer. Thank
you.
