La utilidad máxima esperada por la venta de televisores en una tienda departamental para el primer mes se representa por la sigu
finlep [7]

Explicación paso a paso:

La ganancia máxima esperada ocurre cuando dU / dx = 0

Dada la función U = - x2 + 500x + 100,000

dU / dx = -2x + 500

Dado que dU / dx = 0

Por lo tanto -2x + 500 = 0

Solución para x;

-2x = -500

x = 500/2

x = 250

Sustituya x = 250 en la función para obtener la máxima ganancia esperada como se muestra;

U = - (250) ^ 2 + 500 (250) + 100.000

U = -62500 + 125000 + 100000

U = 162,500 '

Por lo tanto, la ganancia máxima esperada por las ventas es de 162,500

an angle measures 58.4° more than the measure of its supplementary angle what is the measure of each angle
olga55 [171]

Answer:

58.4

119.2

Step-by-step explanation:

Givens

Let one angle = x

Let the other angle = x + 58.4

Together they make 180 degrees.

Equation

x + x + 58.4 = 180                Collect like terms.

Solution

2x + 58.4 = 180                    Subtract 58.4 from both sides

2x  = 180 - 58.4

2x = 121.6                              Divide by 2

x = 60.8

Answer

x = 60.8

x + 58.4 = 119.2
