The graph for the height of a diving board above the water level, h(t), in feet after t
seconds passes through the points (0,5),
(3, -1), and (5,15). Sketch a graph of the
quadratic function that models the situation.
Find the point that represents the minimum
height of the bird.

Grace is standing 18 feet from a lighthouse and kelly is standing 10 feet from grace. the angle that grace looks up to see the top of the lighthouse is 45°. the angle that kelly looks up to see the top of the lighthouse is y°. find the height, h, of the lighthouse. find the angle, rounded to the nearest tenth of a degree, in which kelly looks up to the top of the lighthouse. to the nearest tenth of a degree, find the value of x° . in two or more sentences, explain your calculations
