a trapiziod has vertices A(-2,3) B(4,1) C(-1,-1) and D(2,-2). prove that the line joining the midpoints of the non-parallel sides is the average length of the two parallel sides of the trapaziod.

1. The number of hours of daylight D(t) in Halifax at day t can be approximated by the function D(t) = a sin(bt + c) + d, where t = 1 on January 1, and t = 365 on December 31. The period is one year, and the cycle starts on the vernal equinox, March 21, w...
