4x + 4 = 9x - 36 my answer is 8
5h - 9 = -16 + 6h

Not knowing what your teacher will recognize, it's hard to say, but I'd guess an octagon would be easy enough. Start with a square, with vertices at, say, (1,1)(5,1)(5,5)(1,5) Now add another four points near the midpoints of the sides, say at (3,0)(6,3)(3,6)(0,3) Now ...
Calculus (check my work)
no, R(11) is just that. No derivative. It's showing you how the marginal revenue can be approximated by noting the increase in revenue from one point to another. R(11) = 759 R(10) = 700 ∆R = 59, which is pretty close to R'(10)
max R when R'=0 R' = -2x+400 R'=0 when x=200 In a way, you are on the right track. R is a parabola, whose vertex is midway between the roots. That is, at x=200. Using R' always works, though, even when R is not a nice easy function like a quadratic. This is a c...

P(x) = R(x)-C(x) = -2x^2+360x-100 P'(x) = -4x+360 P'=0 at x=90 P(90)=16100 good work AvgCost A(x) = C(x)/x = x+40+100/x A'(x) = 1-100/x^2 A'=0 at x=10 A(10) = 60
if you can find the critical numbers, that is where the derivative is zero. That is the point of min/max of the function. Check some of the related links below; you will find such problems worked out. Also, a net search for minimum revenue and such will produce many examples s...
revenue is price * quantity profit is revenue - cost avg cost is totalcost/quantity as usual, max/min is found via the derivative
