Is the line through (−4, −6, 1) and (−2, 0, −3) parallel to the line through (12, 20, 7) and (7, 5, 17)?

aksik [14]

Answer:

yes

Step-by-step explanation:

A line is a one-dimensional figure having no thickness and extends infinitely in both directions.

Direction ratios of the line joining points $\left ( x_1,y_1,z_1 \right )\,,\,\left ( x_2,y_2,z_2 \right )$ are given by $\left ( x_2-x_1,y_2-y_1,z_2-z_1 \right )$ .

Direction ratio is a number proportional to the direction cosine.

Direction ratios of a line joining points (−4, −6, 1) and (−2, 0, −3):

$\left ( -2+4,0+6,-3-1 \right )=\left ( 2,6,-4 \right )$

Direction ratios of a line joining points (12, 20, 7) and (7, 5, 17): $\left ( 7-12,5-20,17-7 \right )=\left ( -5,-15,10 \right )$

Ratios of the direction ratios:

$\frac{2}{-5}=\frac{6}{-15}=\frac{-4}{10}=\frac{2}{5}$

We know that two lines are proportional if their direction ratios are proportional.

So, the given lines are parallel.

Two pyramids like the one below sit on top of the gates at the entrance to the bridge. A square pyramid. The base is 10 inches b

Gwar [14]

Answer:

Step-by-step explanation:

We need to find the volume of the pyramid. The volume of a square pyramid is denoted by: $V=\frac{1}{3} Bh$ , where B is the base area and h is the height.

Here, we know that the height of the pyramid is 12 and that the square base has dimensions 10 by 10. That means the base area is just 10 * 10 and the height is h = 12.

Plug these into the equation:

$V=\frac{1}{3} *10*10*12$

Thus, the answer is A.

Hope this helps!
