Use the coordinate plane, the figure below, coordinate proof strategies, and the lengths and slopes of pm and gr to verify this theorem: given: quad is a quadrilateral. p, g, r, m are the midpoints of the sides qu, ua, ad, and dq respectively. prove: the polygon formed by joining adjacent midpoints of a quadrilateral is a parallelogram.

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet
