    Optimization Problem Help


    (a) Show that C^2=(2x^3)/(2x-8.5)
    (b) Find the domain of C.
    (c) Determine the x-value that minimizes C.
    (d) Determine the minimum length of C.

    I am unsure on how to approach this problem.... it would seem that I would need more angle information. It seems I could solve the left region of the polygon, but I have no idea what to do with the right-hand portion.

    Set up equations now and this should be easy.

    EDIT: Did you get your equations?
