Answer:

Step-by-step explanation:

Co-ordinate of point P(0,0,0)

Q (-4,3,-1)

R (-4,2,-2)

S (-8,5,-3)

\vec{PQ}=

\vec{PS}=

Area of Parallelogram =|\vec{PQ}\times \vec{PS}|

Area=\begin{vmatrix}i &j &k \\ -4 &3 &-1 \\ -8 &5 &-3 \end{vmatrix}

A=|\hat{i}(-9+5)-\hat{j}(-12-8)+\hat{k}(-20+24)|

A=|-4\hat{i}+20\hat{j}+4\hat{k}|

A=\sqrt{(-4)^2+(20)^2+(4)^2}

A=\sqrt{432}

A=20.78\ unit^2

Vanyuwa [196]

Answer:

The correct answer is the last choice. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.

Step-by-step explanation:

In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.

In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words, it didn't move.

In the last segment, it moved up again for 2 hours.
