Thanks. Just two questions, already corrected most on District 1.
36. Points A, B, C, and D are on a circle O such that segment PA is a secant to circle O through point B and segment PC is a secant to circle O through point D. If PB=14", AB=20", PD=10" then CD=?
(a) 37[unparseable or potentially dangerous latex formula]
I used the power of a point theorem and got 47[unparseable or potentially dangerous latex formula] as the answer.
57. Given the function [unparseable or potentially dangerous latex formula] there is a possibility of how many positive real zeroes?
(b) 3 or 1
Anyways, is it me or does the test look so much easier when you go over it slowly?
