In 2004, the highest space plane flight was made by Brian Binnie in Space Sip One. A flight with this altitude can be modeled by the function h = -0.17t^2 + 187t + 61000, where h is the altitude in meters and t is flight time in seconds. What was the highest altitude reached by the space plane?

He concluded that a heavier object dropped from the same height as a lighter object will land

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
