Question
The cost, c(x), in dollars per hour of running a certain cruise ship is modelled by the quadratic function c(x)=2.6x^2-18.2x+160.2, where x is the speed
The cost, c(x), in dollars per hour of running a certain cruise ship is modelled by the quadratic function c(x)=2.6x^2-18.2x+160.2, where x is the speed in kilometers per hour. At what speed should the boat travel to achieve the minimum cost?
