The revenue is given by the unit price * number of units.
Profit = Revenue - Cost = 200x - 500,000 - 80x - 0.003x^2 = 120x - 500,000 - 0.003x^2
For profit to be maximum dP/dx = 0
120 - 0.006x = 0
x = 120/0.006 = 20,000
Therefore, to maximize profit, the firm should produce 20,000 penicillin.

Answer: 416 cubic feet</h3>
=========================================================
Explanation:
The volume of any block is V = L*W*H where L,W,H represents length, width and height respectively. The order of multiplication doesn't matter.
The volume of the block on top is 16*4*4 = 256 cubic feet. The "16" is from the fact we subtract the 20 ft and 4 ft.
The volume of the block underneath is 10*4*4 = 160 cubic feet
Add the two volumes to get the final answer: 256+160 = 416 cubic feet.
We can abbreviate "cubic feet" into "ft^3" without quotes.
Answer: 12/13, i think
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Required
Determine the roots
To get the root of the function, then f(b) must be 0;
i.e. f(b) = 0
So, the expression becomes
Add 75 to both sides
Take square roots of both sides
Reorder
Expand 75 as a product of 25 and 3
Split the expression
The options are not clear enough; however the roots of the equation are
