Question 290291: Can someone help me finish this? I am in Iraq fighting with this crappy internet bout to fail pleeeeeease help!!! Just need the last four answers. THANKS!!
Suppose you are an event coordinator for a large performance theater. One of the hottest new Broadway musicals has started to tour and your city is the first stop on the tour. You need to supply information about projected ticket sales to the box office manager. The box office manager uses this information to anticipate staffing needs until the tickets sell out. You provide the manager with a quadratic equation that models the expected number of ticket sales for each day x. ( is the day tickets go on sale).

a. Does the graph of this equation open up or down? How did you determine this?
It opens down because the x^2 term is a negative.
b. Describe what happens to the tickets sales as time passes.
Over time the sales rise, peak then begin to fall.
c. Use the quadratic equation to determine the last day that tickets will be sold.
The last day of ticket sales will be on the 60.9th(61ST)day after going on sale
Note. Write your answer in terms of the number of days after ticket sales begin.

d. Will tickets peak or be at a low during the middle of the sale? How do you know?
The ticket sales will peak during the middle of the sale.
e. After how many days will the peak or low occur?
The peak occurs on the 30th day of sales.

f. How many tickets will be sold on the day when the peak or low occurs?

g. What is the point of the vertex? How does this number relate to your answers in parts e. and f?

h. How many solutions are there to the equation ? How do you know?

i. What do the solutions represent? Is there a solution that does not make sense? If so, in what ways does the solution not make sense?

I already answered all but f.
f)For that just plug in x=30 and solve
g)That will be the other part of the vertex
h) told you two
I)remember I told you that they sold tickets before they started to sell tickets.
