A company estimates that the demand for its product fluctuates with the price it charges. The demand function is given as:
q = 100,000 - 200p

Where .q. equals the number of units demanded and .p. equals the price in rupees. The total cost of producing q units of the product is estimated by the function:

C = 150,000 + 100q + 0.003q2
Required:

a.Determine how many units of q should be produced in order to maximize annual profit?
b.What price should be charged?
c.What is the annual profit expected to equal?
determine the mass of the lamina corresponding to the first quadrant portion of the circle x^2+y^2 =25 where the density at thr point of (x,y) is f(x,y)=k*sqrt(x^2+y^2)
The demand function for a firm’s product is
q=150,000-75p
Where q equals the numbers of units demanded and p equals the price in dollars.
Determine the price which should be charged to maximize total revenue.
What is maximum value for total revenue
How many units are expected to be demanded?
A closed cylindrical tin is of height h cm and radius r cm, its total surface area is A cm2 and its volume is r cm3. Find an expression for A in terms of r . Taking , find an expression of v in terms of r , hence determine the value of r which make v maximum.
A window consists of a rectangular piece of clear glass with a semicircular piece of
colored glass on top; the colored glass transmits only 1/2 as much light per unit area as the the clear
glass. If the distance from top to bottom (across both the rectangle and the semicircle) is 2 meters and
the window may be no more than 1.5 meters wide, find the dimensions of the rectangular portion of the
window that lets through the most light.
The temperature of an object is given by T ( t ) = 280 + 1.5 t 2 e − 0.12 t where t is measured in minutes and T is measured in Kelvins (abbreviated K). (a) Find the rate of change of the rate of change of temperature at the instant t = 20 minutes.
The sides of an equilateral triangle are decreasing at a rate of 3 in/hr. How fast is the area enclosed by the triangle decreasing when the sides are 2 feet long?
Determine the length of y =(3x +2)^2 1<x<4


Cylindrical soup cans are to be manufactured to contain a given volume V . No waste is involved in cutting the material for the vertical side of each can, but each top and bottom which are circles of radius r, are cut from a square that measures 2r units on each side. Thus the material used to manufacture each soup can has an area of A = 2πrh + 8r2 square units.

(a) How much material is wasted in making each soup can?

(b) Find the ratio of the height to diameter for the most economical can (i.e. requiring the least amount of material for manufacture.)

(c) Use either the fi rst or second derivative test to verify that you have min-imized the amount of material used for making each can.


Find f(x) and g(x) so that the function can be described as y = f(g(x)).


y = 8/x^2 + 2
