a closed box with a square base is made of material that's costs 10$ per m squared for the top and bottom and 5$ per meter squared for the sides.
express the cost of the box as a function of x and h. ( h being the height and x being the length and width)
if the voloume is 8 meters cubed than express the cost as a function of x alone.
also if you can help h(x) = x cubed/ 2
how do I find that inverse ?
How do I find a rule
and how do you show that they are inverses ?
also are all inverses reflections of some sort??
Please help me , I work so hard but I'm really confused!!
:confused:
Thank you so much!
