Un prisma cuadrangular regular tiene 4 m de arista de la base y 6m de altura Calcula el area y el volumen

mario62 [17]

Answer:

El área y volumen del prisma cuadrangular mencionado son respectivamente:

Área = $16m^{2}$
Volumen = $96m^{3}$

Step-by-step explanation:

Para solucionar este ejercicio debes recordar que un prisma cuadrangular tiene como base y como superficie cuadrados, por lo tanto, para calcular el área de dicho cuadrado puedes utilizar la siguiente fórmula:

Área de un cuadrado = $arista^{2}$

Ya que el ejercicio nos da el valor de la arista (4 metros), podemos reemplazarla en la ecuación y calcular:

Área de un cuadrado = $(4m)^{2}$
Área de un cuadrado = $16m^{2}$

Por último, para calcular el volumen debes multiplicar el área superficial, el área del cuadrado calculado, por la altura del prisma, cuyo valor dentro del enunciado es de 6 metros, de esta forma:

Volumen de un prisma cuadrangular = área superficial * altura
Volumen de un prisma cuadrangular = $16m^{2}$ * $6 m$
Volumen de un prisma cuadrangular = $96m^{3}$

Como puedes ver tras los cálculos, el área superficial del prisma es de $16m^{2}$ y su volumen es $96m^{3}$ .

Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the ai

sashaice [31]

The probability that the aircraft is overloaded is 0.6141; since this is a greater than 50% chance, the pilot should either reduce the number of passengers on the plane or require them to reduce their baggage.

The z-score for this is given by

z = (X-μ)/σ = (169-180.2)/38 = -11.2/38 = -0.29.

Using a z-table (http://www.z-table.com) we see that the probability of weights being less than this (the area to the left of this score) is 0.3859; to find the probability that the weight is greater than this (to the right), we subtract from 1:

1-0.3859 = 0.6141.

Complete the table of values for y = 6 - 2x

Tpy6a [65]

Step-by-step explanation:

a) substitute x values:

6-2(0) = 6

6-2(1) = 4

6-2(2) = 2

6-2(3) = 0

6-2(4) = -2

6-2(5) = -4

b) rewrite equation as y=-2x+6.

this shows a negative slope with a y-intercept of 6.

c) 3=6-2x

-6 -6

-3 = -2x

divide both sided by 2

-3/-2 = x

3/2=x
