Calculus Optimization Problem.. =(?
the average worker at wakefield avionics can assemble N(t) = -2t^3 + 12t^2 + 2t
(0 <= t <= 4)
ready to fly radio controlled model airplanes t hr into the 8 am to 12 noon morning shift. at what time during this shift is the average woker performing at peak efficiency? Thanks for your time
dN/dt = -6t^2 + 24t + 2 = 0
divide by - 2 :
3t^2 - 12t - 1 = 0
solve for t
