The cost of controlling emissions at a firm rises rapidly as the amount of emissions reduced increases. Here is a possible model

Nadusha1986 [10]

Answer:

$\bar C = 4100\,dollars$

Step-by-step explanation:

a) The average value of a function is given by the following integral:

$\bar C = \frac{\int\limits^{q_{max}}_{0} {4100+90\cdot q^{2}} \, dq }{q_{max}}$

$\bar C = \frac{1}{q_{max}}\cdot \left(4100\cdot q_{max} + 30\cdot q_{max}^{3} \right)$

$\bar C = 4100 + 30\cdot q_{max}^{2}$

b) The determination of the minimum average daily cost per pound of pollutant is done by the First Derivative Test and the Second Derivative Test, which is:

$\bar C' = 60\cdot q_{max}$

$60\cdot q_{max} = 0$

$q_{max} = 0$

$\bar C'' = 60$ (absolute minimum).

The level of reduction corresponding to the lowest average daily cost per pound of pollutant is:

$\bar C = 4100\,dollars$

Solve systems of equations algebraically x+y=6 and 2x+3y=13

HACTEHA [7]

X+y=6 is.....
solve for x=0... y=6
solve for y=0... x=6
intersect x-axis at (6,0)... calculate the slop: solve for x=1... 1+y=6... 6-1= 5 y=5
calculate the slope: a= y(x=1)-y(x=0)/1=-1
x+y=6
