Question 5 In 1999, the population of Richmond-Petersburg, Virginia, metropolitan area, was 961,400 and was
increasing at a at roughly 9200 people per year. The average annual income in the area was $30,593
per capita, and this average was increasing at about $1400 per year. Use the product rule to estimate
the rate at which total personal income was rising in the area at this time. Explain the meaning of
each term in the product rule.
Question 6 Use Logarithmic differentiation to prove the product rule and the quotient rule. Hint: Let f(x) =
A(x)B(x) and g(x) = C(x)/D(x) to start then take the natural log of both sides of each equation and
then take the derivative of both sides of the equation.
Question 7 Use Logarithmic differentiation to find the derivative of a" for a positive constant a.
2) The Nikkei 225 index is a stock market index for the Tokyo Stock Exchange. The
Nikkei 225 index for the period 1990-2010 can be modeled by
V (t) = 23,500e-0.0381t
where t is the number of years after 1990. Determine how many years after 1990 the
Nikkei 225 index reached $20,000.
III. In a particular very small region, the consumer price index, C, depends on the current value of
gross regional domestic expenditure E, number of people living in poverty P, and the average
number of household members in a family F, by the following formula:
-EP
C = 100 +
F
If it is known that the gross regional domestic expenditure is decreasing at a rate of PHP 50 per
year, and the number of people living in poverty and the average number of household members
in a family are increasing at 3 and 1 per year, resp., how fast does the consumer price index
change per year at the moment when E = 1, 000, P = 200, and F = 5?
