Problema envolvendo derivada e equação do segundo grau
Um fabricante de móveis estima que o custo semanal da fabricação de x reproduções (manuais) de uma mesa colonial é dado por C(x) = x3³? 3x² ? 80x+ 500. Cada mesa é vendida por R$ 2.800, 00. Que produção semanal maximizará o lucro? Qual o máximo lucro semanal possível?
Usei a seguinte formula e agora?
L= 2800x -( x³ – 3x² -80x +500)
L= 2800x -x³ +3x² +80x -500
L= -x³ +3x² +80x +2800x -500
L= -x³ +3x² +2880x -500
L= -3x² + 6x + 2880(-1)
L= 3X² -6X – 2880
usando BASKARA
X\’= 32 e X\” = 30
