Answer:

<u>Height of the pyramid:</u>

h = $\sqrt{22.1^2 - (28/2)^2}$ = $\sqrt{292.41}$ = 17.1 m

<u>Volume:</u>

V = 1/3Bh
V = 1/3*28²*17.1 = 4468.8 m³

FORMULA:

Volume of pyramid = L × B × H/3

Height of pyramid = 3V/area of base(L × B)

ANSWER:

So, we have to just plug the respective value.

Height of given pyramid = √(22.1² - 14²)

√(488.41 - 196)
√292.41 = 17.1m

Now, Volume of given pyramid = 28 × 28 × 17.1/3

784 × 17.1/3
4468.8m³

Consider the line x+5y=6

Tems11 [23]

Answer:

$x + 5y = 6$ is perpendicular to $y = 5x + \frac{6}{5}$ and parallel to $y = -\frac{1}{5}x + 2\\$

Step-by-step explanation:

First, convert the equation to standard form so that y is isolated.

x + 5y = 6 --> x - 6 = -5y (divide both sides by -5) --> $y = -\frac{1}{5}x + \frac{6}{5}$

A perpendicular line will have a slope that is the opposite reciprocal of the original slope (meaning you flip the numerator and denominator then make it negative).

$-\frac{1}{5}$ is perpendicular to $-(\frac{-5}{1} )$ which simplifies to 5.

A parallel line will have the same slope, but the y-intercept will be different. It can be pretty much any number as long as the original slope is used in the new equation.

$y = -\frac{1}{5}x + \frac{6}{5}\\$ is parallel to $y = -\frac{1}{5}x + 2\\$ just like $y = -\frac{1}{5}x - \frac{100}{23}$ .
