I need to solve this question by finding the maximum using differentiation. But word problems are my major weakness. I can't seem to construct an equation/graph based on the given data.
The sum of two real numbers x and y is 12. Find the maximum value of their product xy.
Help please...
Alright, thank you. Solved the rest.
Now another word problem that I cannot solve.
A rectangular sheet of metal measures 50cm by 40cm. Equal squares of side x cm are cut from each corner and discarded. The sheet is then folded up to make a tray of depth x cm. What is the domain of possible values of x? Find the value of x which maximizes the capacity of the tray.
