The answer is 4.51.............
Answer:
The rectangular prism boxes should be used because they will cost the company $2.50 less than using the cylindrical containers.
Step-by-step explanation:
Box
2400/60 * .5 = 20
Cylinder
2400/80 * .75 = 22.5
Box cost 2.50 less
<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>
<em><u>Solution:</u></em>
<em><u>Given is:</u></em>

We have to find the vertex and axis of symmetry
<em><u>The general equation is given as:</u></em>

Comparing with given equation,
a = 2
b = 0
c = -1
<em><u>The axis of symmetry is given as:</u></em>


Thus axis of symmetry is 0
The x coordinate of the vertex is the same
x coordinate of the vertex = 0
h = 0
The y coordinate of the vertex is:
k = f(h)
k = f(0)

Thus, y coordinate of the vertex is -1
Therefore, vertex is (0, -1)
