Answer

Find out the  the vertical height (h)of the tetrahedron .

To prove

By using the pythagorus theorem

Hypotenuse² = Perpendicular² + Base²

As given

The Tetrahedron Superyacht designed by Jonathan Schwinge is a regular tetrahedron with edges 20 m long.

The distance r from one corner to the center of the base is 11.5 m.

As shown in the diagram given below.

AB² = AD² + DB²

As given in the question

AD = h , AB = 20 m , DB = 11.5 m

Put in the above

(20)² = h² + (11.5)²

h² =  (20)² - (11.5)²

h² = 400 - 132.25

h² = 267.75

h = \sqrt{267.75}

h = 16.36 m (approx)

Therefore the vertical height,h ,of the tetrahedron is 16.36 m (approx) .

What is the Slope of a line That contains (2,5) and (3, 1) Sketch the graph. Need help with this question.​
Svetach [21]

Answer:

-4/1

Step-by-step explanation:

To find the slope, first plot the two points we are given on the provided coordinate plain. Then using rise/run (slope) find the distance between the two points going up and over or rising and running. So we go up 4 and over 1, this means the slope is 4/1. Since the line we just graphed is going top left towards bottom right, it is negative.

What is the equation of the line that is parallel to the given line and passes theought the point (12, -2)
Nesterboy [21]

Answer:

<u>Option </u><u>D</u> (y = 5/6x -12).

Step-by-step explanation:

Hey there!

The equation of the line which passes through the point (12,-2) is (y+2) = m2(x-12)………(i) [Using one point formula].

According to the question, the first line passes through point (12,6) and (0,-4).

So,

slope(m1) =  \frac{y2 - y1}{x2 - x1}

or \: m1 =  \frac{ - 4 - 6}{0 - 12}

or \: m1 =   \frac{5}{6}

Therefore, the slope of the line is 5/6.

Now as per the condition of parallel lines, m1 =m2 = 5/6.

So, keeping the value of m2 in equation (i), we get;

(y+2) = 5/6(x-12)

y + 2 =  \frac{5}{6} x - 10

or, y = 5/6x - 12.

Therefore, the required equation is y = 5/6 X - 12.

<u>Hope</u><u> </u><u>it </u><u>helps</u><u>!</u>
