Verified answer

1. P(5)= -475

P(50)= 2000

P(120)= -2200

2. Can't graph here...

3. The x-intercepts are 100 and 10. This means that you make profit when x is between 10 and 100

4. Vertex is where x=-b/2a or x=55

Vertex = (55, 2025)

This means at x=55, you make 2025

for P(5) you just set x=5 in your equation and evaluate so P(5)= -5^2 + 110*5 - 1000

graph using the points you find

when they profit function crosses the x axis it means it's no longer profitable

vertex is at x=1/50 then plug in to find y

this vertex represents maximum profit

The gist of the communicate available (sorry, there are too many pages to offer each and all the hyperlinks) is that wands help to concentration the magic resident interior the witch or wizard, yet wandless magic continues to be available, extremely for terribly proficient people like Snape and Dumbledore. some examples ...
