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:
45/28
Step-by-step explanation:
Hey There!
They want us to find the tangent of R
Remember in sohcahTOA
t - tangent
o - opposite
a - adjacent
meaning that
The opposite of angle r is 45
the adjacent of angle r is 28
so 
For this case we have an equation of the form:
This equation in vertex form is:
where (h, k) is the vertex of the parabola.
We have the following function:
We look for the vertice.
For this, we derive the equation:
We equal zero and clear the value of x:
Substitute the value of x = -7 in the function:
Then, the vertice is:
Substituting values we have:
Answer:
The quadratic function in vertex form is:
