Answer:
20ft
Step-by-step explanation:
-16t² + 32t + 4
The main goal to find the maximum height is to find the vertex of the parabola because the vertex is always the minimum or the maximum value.
To find the x value of the vertex, use the formula x =
The a-value is the first coefficient and the b value is the second coefficient:
x =
x = 1
We can say x = t because t is the x value in the equation.
Now, we can substitute x back into the original equation to find the y-value for the vertex.
y = -16t² + 32t + 4
y = -16(1)² + 32(1) + 4
y = -16(1) + 32 + 4
y = -16 + 32 + 4
y = 20
In a word problem, height is typically the y-value and time is typically the x-value. Since t = x, the answer is 20.
