Mr. roberts is the soil conservation agent for caddo county and just completed a study of the feral hog population in the county. he created the expression below to represent the projected population after t years. which statement below best describes the coefficient, 94? a. the size of the initial population b. the rate at which the population was changing before the study c. the rate at which the population is changing d. the size of the yearly population change

Here is their argument. given the obtuse angle x, we make a quadrilateral abcd with ∠dab = x, and ∠abc = 90◦, and ad = bc. say the perpendicular bisector to dc meets the perpendicular bisector to ab at p. then pa = pb and pc = pd. so the triangles pad and pbc have equal sides and are congruent. thus ∠pad = ∠pbc. but pab is isosceles, hence ∠pab = ∠pba. subtracting, gives x = ∠pad−∠pab = ∠pbc −∠pba = 90◦. this is a preposterous conclusion – just where is the mistake in the "proof" and why does the argument break down there?

Will mark name all segments skew to bc
