The following function represents the profit p(n), in dollars, that a concert promoter makes by selling tickets for n dollars each:

p(n) = -250n2 + 2,500n - 5,250

part a: what are the zeroes of the above function and what do they represent? show your work. (4 points)

part b: find the maximum profit by completing the square of the function p(n). show the steps of your work. (4 points)

part c: what is the axis of symmetry of the function p(n)? (2 points)

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
