In Business, the following functions are important.
Revenue function = (price per unit) . (quantity of units) Symbols:
Cost function = (average cost per unit) . (quantity of units) Symbols:
Profit function = revenue − cost
Symbols:
Sometimes in a problem some of these functions are given. Note: Do not confuse p and P .
The price per unit p is also called the demand function p .
Marginal Functions:
The derivative of a function is called marginal function.
The derivative of the revenue function R(x) is called marginal revenue with notation: The derivative of the cost function C(x) is called marginal cost with notation:
The derivative of the profit function P(x) is called marginal profit with notation:
Example 1: Given the price in dollar per unit p = −3x2 + 600x , find: (a) the marginal revenue at x = 300 units. Interpret the result.
R=p.x
C=C.x
P=R−C
R′(x) = dR dx
C′(x) = dC dx
P′(x) = dP dx
revenue function: R(x) = p . x = (−3x2 + 600x) . x = −3x3 + 600x2 marginal revenue: R′(x) = dR = −9x2 + 1200x
dx
marginalrevenueat x=300 =⇒ R′(300)= dR =−9(300)2+1200(300)=−450000
dx x=300
Interpretation: If production increases from 300 to 301 units, the revenue decreases by 450 000 dollars.
(b) the marginal revenue at x = 100 units. Interpret the result. revenue function: R(x) = p . x = (−3x2 + 600x) . x = −3x3 + 600x2
marginal revenue: R′(x) = dR = −9x2 + 1200x dx
marginalrevenueat x=100 =⇒ R′(100)= dR =−9(100)2+1200(100)=30000 dx x=100
Interpretation: If production increases from 100 to 101 units, the revenue increases by 30 000 dollars.

Evaluate the surface integral. ??s (x2 y2 z2 ds s is the part of the cylinder x2 y2 = 4 that lies between the planes z = 0 and z
kondor19780726 [428]
The surface S can be parameterized by

\mathbf r(\theta,z)=(2\cos\theta,2\sin\theta,z)

where 0\le\theta\le2\pi and 0\le z\le2. Then the surface integral can be computed with

\displaystyle\iint_S(x^2+y^2+z^2)\,\mathrm dS
\displaystyle=\int_{\theta=0}^{\theta=2\pi}\int_{z=0}^{z=2}(4\cos^2\theta+4\sin^2\theta+z^2)\|\mathbf r_\theta\times\mathbf r_z\|\,\mathrm dz\,\mathrm d\theta=\dfrac{128\pi}3

Emily is making a punch that contains 75% apple juice and the rest ginger ale. The punch has 2 liters of ginger ale.
Flura [38]
For this item, we may let x be the number or liters of apple juice present in the ginger ale. The total volume of the punch then becomes
                                 total volume = 2 + x 
Then, considering that 75% of this is apple juice,
                                  x/(2 + x) = 0.75
                                   x = 0.75(2 + x) = 1.5 + 0.75x
                                          x = 1.5 + 0.75x
Also, for this item, the vaue of x is equal to 6 liters.
