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 ( $\mathrm { x } )$ weeks after its release. How many units can you expect to sell in week $20 ?$
A) 2600 units
B) 7220 units
C) 11,400 units
D) 6780 units

Quizplus · Accepted Answer

To find the number of units sold in week 20, substitute $x = 20$ into the quadratic model: $y = -11(20)^2 + 350(20)$. This simplifies to $y = -11(400) + 7000 = -4400 + 7000 = 2600$ units.

Solve the Problem -Your Company Uses the Quadratic Model y=−11x2+350xy = - 11 x ^ { 2 } + 350 xy=−11x2+350x
