Homework Statement Homework Equations Rd = retardation factor = (1 + (ƥbKd / n)) log(Koc) = -0.55logS + 3.64 Kd = Koc*foc The Attempt at a Solution Part C is the only part I feel sure on. I simply plugged 1480 mg/L into the log(Koc) equation above to solve for Koc. Then I multiplied Koc...

Ok so for the line segments of the triangle I got x=3, y=0, and y=x Along the segment x=3, I plugged 3 in for x in the original function and got 5y2-20y+9 When evaluating this for y for 0 and 3, I got that the max would be y=0 which equals 9, and the min would be y=3 which is -6 Along the...

Homework Statement f(x,y) = x2-4xy+5y2-8y ; enclosed by the triangular region (0,0), (3,0), and (3,3) Find the absolute maximum and minimum Homework Equations N/A The Attempt at a Solution First I took the partial derivatives with respect to x and y: fx = 2x - 4y fy = -4x + 10y -8 I...
