Thanks! When it asks to find the rate the area is changing at that point in time, did you get the answer -357/5? Because I did, but it doesn't seem right...

Well, I bet it turns out to be a square but anyway: A = b c where b is breadth and c is length 2 b + 2 c = 800 so b + c = 400 c = (400 - b) so A = b * (400-b) A = 400 b - b^2 b^2 - 400 b + A = 0 where is the vertex of this parabola (I assume you do not do calculus) b^2 - 400 b...

xy=384 so, y = 384/x f = 2x+3y = 2x + 1152/x df/dx = 2 - 1152/x^2 min f is when df/dx=0, at x=24 So, the field is 24x16 f = 48+48=96 as usual in these problems, the fencing is divided equally among lengths and widths.

Calculus - Definite Intergrals
the equilibrium price is where supply equals demand. 71 - 1/10 x = 35 + 1/20 x x = 240 Pmax (the y-intercept of D) is 710 Consumer surplus is thus ∫[240,710] D(x) dx and just take it from there. Similarly for producer surplus.

Integral of x / sqrt(x-1) dx We can use substitution method. Let u = x - 1 Thus, x = u + 1 and dx = du Substituting, Integral of (u+1)/sqrt(u) du Integral of (u+1)(u^(-1/2)) du Integral of u^(1/2) + u^(-1/2) du = (2/3)*u^(3/2) + (2)*u^(1/2) + C = (2/3)*(x-1)^(3/2) + 2(x-1)^(1/...
