Queremos encontrar una ecuación que relacione la <u>cantidad de combustible</u> que una locomotora consume con la distancia que esta recorre.

Veremos que:

a) 318.7 L

b) 796.8 L

c) 120.2 km

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

Veamos como resolver esto.

Primero, sabemos que la locomotora consume 39.9L para moverse una distancia de 10 km.

Entonces la cantidad que se mueve por litro es:

r  = (10 km)/(39.9 L) = 0.251 km/L

Así podemos escribir la ecuación:

D =  (0.251 km/L)*C

Donde D es una distancia y C es la <u>cantidad de combustible que se consume.</u>

a) ¿Cuántos  litros de diésel consumirá para mover la misma carga a 80 km?

Reemplazamos D por 80km y resolvemos para C:

80km =  (0.251 km/L)*C

80km/(0.251 km/L) = C = 318.7 L

b) ¿Cuántos  litros de diésel consumirá para mover la misma carga a 200 km?

Reemplazamos D por 200km y resolvemos para C:

200km =  (0.251 km/L)*C

200km/(0.251 km/L) = C = 796.8 L

c) Si ha consumido 478.8 litros, ¿qué distancia  ha recorrido?

Reemplazamos C por 478.8 L y resolvemos para D:

D = (0.251 km/L)*478.8 L = 120.2 km

If x-2 is one of the factors of x^4-kx^2+4, find the value of k.
Andrei [34K]

Step-by-step explanation:

Given expression is x⁴-kx²+4 =0

x−2 is a factor of the given expression.

So, x=2

Substitute in the equation, we get

2⁴-k(2)²+4

⇒16+4k+4=0

⇒4k=−20

⇒k=−5

And object is traveling at a steady speed of 8 2/3 mph how long will it take to object to travel 5 1/5 miles

\bf \begin{array}{ccll}&#10;miles&hours\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;8\frac{2}{3}&1\\\\&#10;5\frac{1}{5}&h&#10;\end{array}\implies \cfrac{8\frac{2}{3}}{5\frac{1}{5}}=\cfrac{1}{h}\implies \cfrac{\quad \frac{26}{3}\quad }{\frac{26}{5}}=\cfrac{1}{h}\implies \cfrac{26}{3}\cdot \cfrac{5}{26}=\cfrac{1}{h}&#10;\\\\\\&#10;\cfrac{5}{3}=\cfrac{1}{h}\implies 5h=3\implies h=\cfrac{3}{5}

which is just 36 minutes.

A cardboard sheet is cut in the shape of a triangle, with vertices at (0,0), (20,0), and (3,4) units. the thickness of the sheet
kenny6666 [7]
This problem can be solved in two ways, the long way, or the short way.

1. The long way
We know that the base of the triangle is along the x-axis, and the length of the base is 20.
The centre of mass is located at 2/3 of the distance from vertex (3,4) along the median, which cuts the base at (10,0).
Therefore the centre of mass is located at
x=3+(10-3)*2/3=23/3
y=4/3

2. The short way
It turns out that the centre of mass of a triangle sheet is located at the mean of the coordinates of the three vertices, i.e.
CG=((0+20+3)/3, (0+0+4)/3)=(23/3, 4/3)  as before.
