Since we are finding dy/dx when x is 9, we get: dy/dt = (1/2 (sqrt9)^ (-1/2)) (12) dy/dt = (1/2 * 1/3) (12) dy/dt = (1/6) (12) dy/dt = 2. Inx=t+InC. f (x) then derivative is represented as d f (x)/dx. Monod Growth Model. So constant length means that x^2 + h^2 = constant^2, which implies that 2x dx/dt = -2h dh/dt. ∫ dx f(x) = ∫ dt ∫ d x f ( x) = ∫ d t. This gives df dt = (2xyz)et +x2z +x2y . Solution.
