Answer:
Max height: 64 feet, and the socond one was higher.
Step-by-step explanation:
The max height is the y value of the vertex, because that’s when the graph peaks.
we can already very clearly see the vertex on the graph, so we don’t need to calculate it.
the max height of the second golf ball is 64 feet.
Now let’s look at the max height on the first golf ball.
we get the equation
h=-16t squared + 48t
to find the vertex of this, we can use the formula -b/2a
-48/-32 = 1.5
1.5 is the t value of this vertex.
to find the h value, we plug it in.
h = -16 (1.5) squared + 48(1.5)
h =2.25 times -16 + 72
h = -36 +72
h = 36
the first one is 36 max height, and the second is 64. The second one is bigger.
