The first step is to draw the graph. Once we do this, we can easily see that the vertex is at (12,64), which means that the hourly profit of coffee sold is highest at 12 cups of coffee. The x-intercepts are at x = 4 and x = 20, which means that between 0 and 4 (inclusive) cups of coffee sold, and after 20 cups sold, there is no profit.

<em> 7850 ft²</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em>d = 2r => r = d/2 = 100ft/2 = 50 feet</em>
<em>A = πr² </em>
<em>= 3.14×(50ft)² </em>
<em>= 3.14×2500ft²</em>
<em>= 7850 ft²</em>
<em>Good luck !</em>
Answer:
The vertex of the graph of y = x is shifted to the right 3 units and up 4 units.
The vertex of the graph of y = x?is shifted to the right 4 units and up 3 units.
