The cost, in thousands of dollars, of airing x television commercials during a sports event is given by
C(x) = 20 + 5,000x + 0.05x2.
(a) Find the marginal cost function
Use it to estimate how fast the cost is increasing when x=4 ............. thousand dollars
Compare this with the exact cost of airing the fifth commercial.
The cost is going up at the rate of $ per television commercial. The exact cost of airing the fifth commercial is $ . Thus, there is a difference of $ .
(b) Find the average cost function C, and evaluate C(4).
What does the answer tell you?
The average cost of airing the first four commercials is $ per commercial.

If
you were interested in looking at the difference between
commercials shown during daytime television (7am-5pm) and primetime
television (6pm-11pm), what do you think you would find? Why do you
think commercial content is different during these two times? If
you wanted to test your hypotheses, what would your unit of
analysis be? What would your units of observation be?

Feminized faces in TV commercials. Television commercials most
often employ females or “feminized” males to pitch a company’s
product. Research published in Nature (August 27 1998) revealed
that people are, in fact, more attracted to “feminized” faces,
regardless of gender. In one experiment, 50 human subjects viewed
both a Japanese female face and a Caucasian male face on a
computer. Using special computer graphics, each subject could morph
the faces (by making them more feminine or more masculine) until
they...

In a test of the quality of two television commercials, each
commercial was shown in a separate test area six times over a
one-week period. The following week a telephone survey was
conducted to identify individuals who had seen the commercials.
Those individuals were asked to state the primary message in the
commercials. The following results were recorded.

1)The total profit P(x) (in thousands of dollars) from a sale
of x thousand units of a new product is given by
P(x)= ln (-x3+9x2+48x+1) (0≤x≤10).
a) Find the number of units that should be sold in order to
maximize the total profit.
b) What is the maximum profit?
