Solve the problem.
-Your company uses the quadratic model $y = - 11 x ^ { 2 } + 350 x$ to represent how many units ( $y$ ) of a new product will be sold $( x )$ weeks after its release. How many units can you expect to sell in week 12?
A) 5784 units
B) 2616 units
C) 4068 units
D) 4332 units

Quizplus · Accepted Answer

To find the number of units sold in week 12, substitute $x = 12$ into the quadratic model $y = -11x^2 + 350x$. This gives $y = -11(12)^2 + 350(12) = -11(144) + 4200 = -1584 + 4200 = 2616$ units.

Solve the Problem y=−11x2+350xy = - 11 x ^ { 2 } + 350 xy=−11x2+350x

Solve the Problem $y = - 11 x ^ { 2 } + 350 x$
