Question 459923: The number of tickets sole each day for an upcoming performance of Handel's Messiah is given by N(x)=-0.5x^2+12x+11, where x is the number of days since the concert was first announced. When will daily ticket sales peak and how many tickets will be sold that day? Answer by nerdybill(7384) (Show Source):
You can put this solution on YOUR website! N(x)=-0.5x^2+12x+11
It will peak at the vertex. We know this because of the negative coefficient associated with the x^2 term -- that is, the parabola opens downward.
x = -b/(2a)
x = -12/(2(-0.5))
x = -12/(-1)
x = 12
.
ans: it will peak 12 days after concert was first announced
