Abaseball thrown noward at initial speed of 9.5m/s.
the approximate height of the ball, h metres, after t seconds is given by the equation h = -4.9t2 + 9.5t+1.
at the same time, a golf ball is hit upward at an initial speed of 12m/s. the approximate height of the ball, h metres, after t seconds is given by the equation h=-4.9t2 + 12t

a) when are both balls at the same height?

b) what is this height?

a) 0.4 s; b) 4.016 m

Step-by-step explanation:

a) Time to same height

b) Height

Insert the value of t into one of the equations.

The diagram below shows that the trajectories of the balls intersect after 0.4 s at a height of 4.016 m.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

none cuz there are no "following statements" regarding the question
