Joel is planting a garden in the shape of a trapezoid. Three of the sides are the same length, and the fourth side is 18 feet long. He uses 58. 5 feet of fencing to surround the garden. What is the maximum length of each of the other three sides?.

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

It was crowded with sewer like smells. bad sewer systems
