The maximum height is the vertex of y = −4t^2 + 10t.
t = −b/(2a) = −10/(2·−4) = 1.25 s.
y(1.25) = −4(1.25)^2 + 10(1.25) = 6.25 feet.
So the maximum height is 6.25 feet (25/4 ft).
t = −b/(2a) = −10/(2·−4) = 1.25 s.
y(1.25) = −4(1.25)^2 + 10(1.25) = 6.25 feet.
So the maximum height is 6.25 feet (25/4 ft).
