Given p(x), find p(-3) by using synthetic substitution: 1. p(x) = 8x3 + 7x2 + 2x + 4
2. p(x) = 2x3 + 5x2 – 3x

Ok a point t on a segment with endpoints d(1, 4) and f(7, 1) partitions the segment in a 2: 1 ratio. find t. you must show all work to receive credit.

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b

Segment wx is shown explain how you would construct a perpendicular bisector of wx using a compass and a straightedge
