Answer:
36 feet.
Step-by-step explanation:
We have been given that a ball is thrown upward from ground level. Its height h, in feet, above the ground after t seconds is . We are asked to find the maximum height of the ball.
We can see that our given equation is a downward opening parabola, so its maximum height will be the vertex of the parabola.
To find the maximum height of the ball, we need to find y-coordinate of vertex of parabola.
Let us find x-coordinate of parabola using formula .
So, the x-coordinate of the parabola is . Now, we will substitute
in our given equation to find y-coordinate of parabola.
Therefore, the maximum height of the ball is 36 feet.
Answer:
Step-by-step explanation:
Let's substitute the first equation into the second one.
- Multiply by
and bring all the terms to one side.
I'll use my graphical calculator to solve this but you could factor:
(All rounded to 2 decimal places)
Now we can substitute these values into an equation for
.
