violet throws a ball up in the air. the graph below shows the height of the ball h in feet after t seconds. how many seconds have gone by when the ball is at its highest point?

violet throws a ball up in the air. the graph below shows the height of the ball h in feet after t seconds. how many seconds have gone by when the ball is at its highest point?

Answer

Explanation:

Step1: Identify the highest - point on the graph

The highest point of the graph of height $h$ vs time $t$ is given as the vertex of the parabola. The vertex of the parabola in the form $(t, h)$ is $(0.75,9)$.

Step2: Determine the time value

We are interested in the time $t$ when the ball is at its highest point. From the vertex coordinates $(0.75,9)$, the $t$ - value is $0.75$.

Answer:

$0.75$
