Part 1
An athlete whose event is the shot put releases the shot. When the shot is released at an angle of
2525°,
its path can be modeled by the formula
y equals negative 0.01 x squared plus 0.5 x plus 5.9y=−0.01x2+0.5x+5.9
in which x is the shot's horizontal distance, in feet, and y is its height, in feet. This formula is shown by one of the graphs, (a) or (b), in the figure. Use the formula to answer the questions below.
(a)(b)
A coordinate system has a horizontal axis labeled Horizontal Distance from 0 to 160 in increments of 20 and a vertical axis labeled Height from 0 to 20 in increments of 5. There are two curves, labeled (a) and (b) both starting from a (0, 5.9). The curve labeled (a) rises at a decreasing rate to a maximum at (25, 12.15) before falling at an increasing rate to (59.9, 0). The curve labeled (b) rises at a decreasing rate to (25, 6.28) before falling at an increasing rate to (127.3, 0). All coordinates are approximate.
Horizontal Distance[0,160,20] by [0,20,5]
