Answer by ankor@dixie-net.com(15636)   (Show Source): You can put this solution on YOUR website! The number of tickets sold each day for an upcoming performance of Handel's Messiah is given by N(x)=-0.4x^2+8.8x+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? : N(x)=-0.4x^2 + 8.8x + 11 Find the axis of symmetry: x = -b/(2a), in this equation a=-.4; b=8.8 x = x = x = +11 days since announced : Find the no. of tickets, substitute 11 for x N(x) = -0.4(11^2) + 8.8(11) + 11 N(x)=-0.4(121) + 96.8 + 11 N(x)= -48.4 + 96.8 + 11 N(x) = 59.4 ~ 59 tickets sold on the 11th day
