<h2>Answer:   y - 5 =  - 4 (x - 4)</h2>

Step-by-step explanation:

The point-slope form of a line is (y - y₁) = m(x - x₁)

Since we know the slope (m) is -4

And the point  ( x₁, y₁ ) is (4, 5)

Then we can just plug these into the equation above:

                               ⇒  y - 5 =  - 4 (x - 4)

<em>I often use Desmos to check my answer. As seen below, the equation does pass through the point (4, 5).</em>

Calculamos el volumen (V) de un prisma cuadrangular expresado en unidades cúbicas. Respondemos: ¿cómo se calcula?...............
Vadim26 [7]

Answer:

a) El procedimiento queda resumido en lo que sigue:

1) Se halla el área de la base del cuadrilátero.

2) Se multiplica el resultado anterior por la longitud del prisma.

b) La expresión para calcular el volumen del prisma (V), en unidades cúbicas, es:

V = w\cdot h \cdot l

Donde:

w - Ancho de la base, en unidades.

h - Altura de la base, en unidades.

l - Longitud del prisma, en unidades.

Step-by-step explanation:

a) Dimensionalmente hablando, la unidad de volumen es igual al cubo de la unidad de longitud. Se explica a continuación los pasos necesarios para el cálculo de prisma cuadrangular:

1) Se halla el área de la base del cuadrilátero.

2) Se multiplica el resultado anterior por la longitud del prisma.

b) En consecuencia, se deriva la expresión para el volumen del prisma:

V = A\cdot l (1)

Donde:

A - Área de la base del prisma, en unidades cuadradas.

l - Longitud del prisma, en unidades.

V = w\cdot h \cdot l (2)

Donde:

w - Ancho de la base, en unidades.

h - Altura de la base, en unidades.
