<u>Part A</u>
<u />
<u>Part B</u>
The vertex of the graph will be a maximum because the leading coefficient is negative.
The x coordinate of the vertex is
.
When x=15/8,
.
So, the vertex has coordinates 
<u>Part C</u>
Plot the two x-intercepts and the vertex and then draw a curve in the shape of a parabola passing through them.
The graph is in the attached image.
36 I believe sorry if it’s wrong what I did was multiply 2x 18 have I nice day good luck!
So the initial question is x / 113 = 3.14 (we're keeping it a smaller decimal for now)
What you should do first is multiply both sides by 113
Your answer should be x = 354.82
Round this up to x = 355. <-- This is why we only used 3.14 at the start
Now check your work:
x / 113 = ?
355 / 113 = 3.14159265358979... which essentially is pi
