Given , revenue function : 
Cost function 
Profit = Revenue - Cost
Hence, P = R(x) - C(x)
Total revenue for x = 12000 is 
Total cost for x = 12000, 
Profit = 60000-28500 = 31500
Answer = 31500
Answer:
±2 sqrt(3) =x
Step-by-step explanation:
12 - x^2 = 0
Add x^2 to each side
12 - x^2 + x^2 = x^2
12 = x^2
Take the square root of each side
±sqrt(12) = sqrt(x^2)
±sqrt(4*3) = sqrt(x^2)
±sqrt(4) sqrt(3) = x
±2 sqrt(3) =x
9 feet above the ground, since it has to be 3 feet away from the wall you would have to subtract those 3 feet from the length of the ladder.
Answer:
the answer is b
Step-by-step explanation:
because p is at (6,4) and its moving to the left so the y wont change but the x will so subtract 10 units from 6 and you get -4.
