The height, s, of a ball thrown straight down with initial speed 64 ft/sec from a cliff 80 feet high is s(t) = -16t2 - 64t + 80, where t is the time elapsed that the ball is in the air. what is the instantaneous velocity of the ball when it hits the ground? (2 points) select one: a. 256 ft/sec b. -96 ft/sec c. 0 ft/sec d. 112 ft/sec the surface area of a right circular cylinder of height 4 feet and radius r feet is given by s(r)=2πrh+2πr2. find the instantaneous rate of change of the surface area with respect to the radius, r, when r = 4. (2 points) select one: a. 24π b. 16π c. 64π d. 20π

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
