If h is vertical height, b=horizontal distance from wall to bottom of ladder and l=lenght of ladder,we can say lsquared = hsquared + b squared. Now differentiate w.r.t. time t. 2l*dl/dt= 2h* dh/dt + 2b*db/dt =0 However this solution doesn't give exactly the same answer when one solves the problem geometrically or using simple pythagorus. For example ,if l=20m and b=12 m and h=16m and db/dt is 2m/s, I calculate dh/dt as !.5 m/s using calculus but 1.717 m/s using geometry or straight Pythagorus. Where is the fallasy inthe method using calculus? Ray Bevan
Foot rests can be bought in a variety of places. One can buy them at furniture stores, home improvement stores, and home supply stores. One may also find foot rests through online retailers.
Fulcrum is the point that a lever rests or is supported.

If the wall is straight and the ground level then this is an outline of a right angle-triangle. If the top of the ladder makes an angle of 530 with the wall then the bottom of the ladder must make 370 to the ground. Use the sine ratio to find the length of the ladder (which will be the hypotenuse) sin = opp/hyp rearranged to hyp = opp/sin hyp = 15/sin370 = 24.92460212 feet So the length of the ladder is 25 feet correct to the nearest foot.
62+82=36+64=100 and the squared route of 100 is 10

It could indicate closeness, comfort, or a desire for intimacy from that person.
The answer is foundation because it means the natural or prepared ground or base on which some structure rests.
the bottom support of anything; that on which a thing stands or rests: a metal base for the table.By:Jorge Alcocer
The tongue rests in your mouth. It fit perfectly in your bottom jaw and is the strongest muscle in your body.
The sink sits on the pedestal and there is a hole or slot on the bottom edge that rests against the wall. A large screw or lag screw is put through these holes and into the wall. There should be a 2x6 or wider board in the wall for this purpose in the original construction.
