PREGUNTA 5Una fábrica produce 300 rodamientos de apoyo a un costo de 3200 dólares, pero si produce 700 el costo es de $4800. Si se sabe que la relación del costo (C) y el número de rodamientos de apoyo (x) es lineal, obtenga una fórmula que exprese esta relación y calcule el costo de producir 950 rodamientos de apoyo.

Answer 1
Answer:

Answer:

C = 4x + 2000 es la ecuación

El costo de los rodamientos de soporte 950 es de $ 5,800

Step-by-step explanation:

Esperamos una gráfica lineal de costo contra el número de rodamiento de respaldo.

Un punto en este diagrama tendrá una representación como (número de demoras, costo)

Ahora, a partir de la pregunta, podemos identificar dos puntos; (300,3200) y (700,4800)

Generalmente, la ecuación de una línea recta tiene la forma

y = mx + c

donde m es la pendiente y c es la intersección en y

Lo que esto significa en esta línea es que tenemos dos cosas para calcular, que es la pendiente de la línea y la intersección de la línea. Usando los dos puntos podemos calcular estos.

matemáticamente, la pendiente se puede calcular como;

tenemos m = (4800-3200) / (700-300) = 1600/400 = 4

Como conocemos la pendiente, el modelo lineal ahora se convierte en

y = 4x + c

Para obtener el valor de la intersección con el eje y, podemos usar cualquiera de los dos puntos. Digamos que queremos usar el primer punto (300,3200)

3200 = 4 (300) + c

3200 = 1,200 + c

c = 3200-1200

c = 2000

Así la ecuación se convierte

y = 4x + 2000

Ahora usemos los parámetros definidos en la pregunta, tenemos;

C = 4x + 2000

donde C es el costo yx es el número de rodamientos de soporte

Ahora queremos calcular el costo de 950 rodamientos

Simplemente usamos la ecuación que hemos modelado donde en este punto, x = 950

C = 4 (950) + 2000

C = $ 5,800

Find the product of 2x4(4x2 + 3x + 1). 8x6 + 6x5 + 2x4

8x8 + 3x4 + 2x4

2x4 + 6x5 + 8x6

6x6 + 5x5 + 3x4

Answers

Answer:

The product of the 2x^(4)(4x^(2)+3x+1) is 8x^(6)+6x^(5)+2x^(4) .

Step-by-step explanation:

As given the expression in the question be

= 2x^(4)(4x^(2)+3x+1)

First open the bracket

= 2x^(4)* 4x^(2)+2x^(4)* 3x+2x^(4)* 1

Now by using the property

x^(a)* x^(b)=x^(a+b)

= 8x^(6)+6x^(5)+2x^(4)

Therefore the product of the 2x^(4)(4x^(2)+3x+1) is 8x^(6)+6x^(5)+2x^(4) .

2x^4(4x^2 + 3x + 1)=\n\n(2x^4)(4x^2)+(2x^4)(3x)+(2x^4)(1)=\n\n8x^6 + 6x^5+2x^4

The answer is A.

Answers

Answer:

x = 2

y = 6 1/3

Step-by-step explanation:

5x - 6y = -32

3x + 6y = 48

-----------------

8x = 16

x = 2

5(2) - 6y = 48

10 - 6y = 48

-6y = 48 - 10

-6y = 38

y = 6 1/3

you want to create a box that can hold at the very longest a 4in object. find the dimensions of a box that will work

Answers


If you were working with a flat rectangle and you were given the diagonal,
you'd want to use the Pythagorean theorem to choose two sides whose
squares would add up to the square of the diagonal.

It works exactly the same with a 3-D box.  We need three dimensions for
the box, whose squares add up to the square of the diagonal between
opposite corners.  That's (4)² = 16.

So (L)² + (W²) + (H²) = 16 . From there, you're completely free to pick any
numbers you want, just as long as their squares add up to 16.  There are
an infinite number of possibilities.  Here are a few:

1 x 1 x √14

1 x 2 x √11

2 x 2 x √8

2 x 3 x √3

1 x 3 x √6
