The maximum safe load for ahorizontal rectangular beam varies jointly with thewidth of the beam and the square of the thickness ofthe beam and inversely with its length. If an 8-foot beamwill support up to 750 pounds when the beam is 4 incheswide and 2 inches thick, what is the maximum safe loadin a similar beam 10 feet long, 6 inches wide, and 2 inchesthick?

The safe load, L, of a wooden beam supported at both ends varies jointly as the width, w, and the square of the depth, d, and inversely as the length, l. A wooden beam 8in. wide, 7in. deep, and 2ft long holds up 27412lb. What load would a beam 5in. wide, 6in. deep, and 18ft. long, of the same material, support? Round your answer to the nearest integer if necessary.

A gardener has 120 feet of fencing and wants to fence off a rectangular garden that borders the back of his property. The back of the property already has a fence. What are the dimensions of the garden that has the largest area? Note: You may consider the length: the value across from the fence that already exists, and the width: the two values that are adjacent to the fence that already exists. Omit units of measurement from your answer. Length = Width =
