find the length of longest pipe that can be carried level around a right angle corner of the two intersecting corridors are the width of 4 feet and 6 feet by calculus 

A steel pipe is being carried down a hallway 9 ft wide. At the end of the hall there is a right-angled turn into a narrower hallway 6 ft wide. What is the length of the longest pipe that can be carried horizontally around the corner?

Two identical right-angled triangles, JKL and MLK, overlap along side KL, as shown. Sides JL and MK intersect at N.
The area of the overlapped region, 4KLN, is equal to half of the area of 4JKL. The area of the figure JKLMN is 48 cm2.

If JK = 6 cm, determine the length of KL.

5. The length of a rectangle is decreasing at the rate of 1 foot per second, but the area remains constant. How fast is the rectangle's width is changing when its length is 10 feet and its width is 5 feet? (10 points) A=lw 4A = 10 + antw. Since A is a constant A = 0 0 = 10 + ( - 1)5 = lot = -
