What is the value of x? sin(x+34)°=cos(2x+20)°
vfiekz [6]
We know that
if sin A=cos B
then 
angle A and angle B are complementary angles
so
A+B=90 degrees
in this problem
(x+34)+(2x+20)=90-------> 3x+54=90----> 3x=90-54-----> x=36/3----> x=12°

the answer is
the value of x is 12 degrees

3. Problema 2: Suponga que un fabricante de radios tiene la función de costo total C (x) = 43x + 1850 dólares y la función de in
allochka39001 [22]

Responder:

$ 11,137

Explicación paso a paso:

Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.

Dado

Función de costo C (x) = 43x + 1850

Función de ingresos R (x) = 80x

Obtener la función de ganancias

P (x) = R (x) - C (x)

P (x) = 80x - (43x + 1850)

P (x) = 80x - 43x - 1850

P (x) = 37x - 1850

Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:

P (351) = 37 (351) - 1850

P (351) = 12,987-1850

P (351) = 11,137

<em>Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137</em>
