Step-by-step explanation:
Answer: 10 1/2, which can be simplified as 10.5
Explanation: First, set up a proportion with acres of corn to time in hours:
8 3/4 acres = x acres
5/6 hour = 1 hour
Reorder the terms:
x = (8 3/4) / (5/6)
To figure that out the math, change the mixed fraction to an improper fraction, and change the division into a multiplication:
x = (35/4) * (6/5)
Next cancel out:
x = (7/2) * (3/1)
x = 21/2
Lower that faction the the lowest denominator:
21/2 = 10½
Thus, your answer is 10½, or in other words 10.5

The axis of symmetry is 1.
To find this, do -b/2a, putting -8 in the place of b and -4 in the place of a. Proceed to solve to get 1.
The equation provided is vertex form, so to find the needed components, you need to solve for the vertex. To do so, implement 1 in as x and solve for the vertex.
The vertex is 1, -16.
(y - 16) = -4(x - 1)^2
Although it is not exactly vertex form, the only difference is that instead of it being +k at the end, it is subtracted with the y.
Hope this helps!
