Arocket is fired upward from some initial distance above the ground. its height in feet, h, above the ground, t seconds after it is fired, is given by h=−16t^2+96t+2560.

what is the rocket's maximum height?

how long does it take for the rocket to reach its max height?

after it's fired, the rocket reaches the ground at t=__ sec.

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?
