Calculus: Early Transcendentals

Match the polar equations with the graphs labeled I-VI. Give reasons for your choices. (Don't use a graphing device.)
(a) $ r = \ln \theta $, $ \; 1 \leqslant \theta \leqslant 6\pi \qquad $ (b) $ r = \theta^2 $, $ \; 0 \leqslant \theta \leqslant 8\pi $
(c) $ r = \cos 3\theta \qquad $ (d) $ r = 2 + \cos 3\theta $
(e) $ r = \cos(\theta/2) \qquad $ (f) $ r = 2 + \cos(3\theta/2) $

According to Salary Wizard, the average base salary for a brand manager in Houston, Texas,
is $\$ 88.592$ and the average base salary for a brand manager in Los Angeles, California, is $\$ 97,417$ (Salary Wizard website, February $27,2008 ) .$ Assume that salaries are normally distributed, the standard deviation for brand managers in Houston is $\$ 19,900,$ and the standard
deviation for brand managers in Los Angeles is $\$ 21,800 .$
a. What is the probability that a brand manager in Houston has a base salary in excess of
$\$ 100,000 ?$
b. What is the probability that a brand manager in Los Angeles has a base salary in excess
of $\$ 100,000 ?$
c. What is the probability that a brand manager in Los Angeles has a base salary of less
than $\$ 75,000 ?$
d. How much would a brand manager in Los Angeles have to make in order to have a
higher salary than 99$\%$ of the brand managers in Houston?
