Calculus
The area bounded between the line y=x+4 and the quadratic function y=(x^2)-2x. Hint: Draw the region and find the intersection of the two graphs. Add and subtract areas until the appropriate area is found. I found the intersection points as (-1,3) and (4,8). I'm not sure w...

Use the five steps for problem solving to answer the following question. Show all work. Andrew is having an irrigation system installed in his yard. Company A charges \$1250 plus \$15 per sprinkler head. Company B charges \$1200 plus \$17 per sprinkler head. How many sprinkler hea...

Carry on with the problem.. To find maximum profit, not revenue, would I take the derivative of the profit function, which I have as Profit=125*(12L+29L^2-1.1^3)-7000L. If I take the derivative of this(which I'm not sure I did right) my L=16.78 or .79. If I plug it back in...

1. So this is the answer I got 12L+29L^2-1.1L^3=0 L(12+29L-1.1L^2)=0 L=0, 26.77, -0.41 The minimum number of laborers would be 0. The maximum number of laborers would be 26.77. THe range would then be (0,26.77) because when I substitute a number >26.77 into the above equati...

I really need help, this is my second post. Information to solve problems Q=12L+29L^2-1.1L^3 Q= # of cars produced/year L=# of laborers used per year for production Each car sells for \$125. \$7000 per laborer per year is cost for labor and other consumable materials. Questions:...
