Para armar un escritorio, Eduardo tendrá que usar 20 tarugos, los que debe cubrir completamente con una capa de pegamento. Él ca
Degger [83]

El área superficial total de los veinte tarugos es mayor que el área superficial cubierta por el pegamento.

<h3>Como determinar si la superficie cubierta por el pegamento es suficiente</h3>

En esta pregunta debemos calcular el área superficial total de los tarugos (A_{s}), en milímetros cuadrados, y comparar el resultado con la cifra afirmada por Eduardo. El área superficial total es:

A_{s} = 20\cdot \pi\cdot (5\,mm)^{2}\cdot (80\,mm)

A_{s} \approx 125663.706\,mm^{2 }

En consecuencia, el área superficial total de los veinte tarugos es mayor que el área superficial cubierta por el pegamento. Francisca tiene la razón. \blacksquare

<h3>Observación</h3>

El enunciado omite las dimensiones <em>geométricas</em> de cada tarugo (5 milímetros de radio y 80 milímetros de longitud).

Which table represents a linear function that has a slope of 5 and a y-intercept of 20?
erastovalidia [21]

Answer:

The first image.

x |  y

-4 | 0

0 | 20  <--- When x = 0, the y value is the y-intercept.

4 | 40

8 | 60

Step-by-step explanation:

To check the slope, we can use the equation (y₂ - y₁) ÷ (x₂ - x₁) using any two pairs given. For this example, I'll use (-4, 0) and (4, 40).

                                                              x₂  y₂         x₁   y₁

(0 - 40) ÷ (-4 - 4)

(-40) ÷ (-8)

<u>Slope = 5</u>

<u></u>

~Hope this helps!~
