x= chronological order of the second letter in your first name
y = is the last digit of your student number; example, 5 in 20x-12345.
(a) DEMAND RATE When the price of a certain commodity is p dollars per unit,
customers demand x hundred units of the commodity, where
f + 3px + p² = 79.
How fast is the demand x changing with respect to time when the price is $5 per
unit and is decreasing at the rate of 30 cents per month?
(b) MANUFACTURING At a certain factory, output Q is related to inputs u and v by
the equation
2u + 30
Q = 3u? +
(u+v)
If the current levels of input are u = 10 and v =
change in input v that should be made to offset a decrease of 0.7 unit in input u so
that output will be maintained at its current level.
