It is true if two vectors point in opposite directions. This means their cross product must be zero.
<h3>What is cross product?</h3>
Cross product is a vector product of two vectors in the three dimensional vector space.
In the case when the two vectors point in opposite directions so there cross product should be zero.
Impact on two points:
In the case when the two vectors point in opposite directions so there cross product should be zero.
Like
A*B = [A][B] sin
Here theta is be the angle that lies between them
So,
A*B = [A][B] sin 180
So, A*B = 0
hence, the given statement is true.

<em><u>The proportion that could be used to solve for the variable is:</u></em>
h = 7.5
<em><u>Solution:</u></em>
Given that,
16 walls in 40 hours 3 walls in h hours
Which means,
16 walls build in 40 hours
Then 3 walls in h hours
We have to write a proportion
The number of walls and the number of hours are proportion
Therefore, we get,
Cross multiply and solve for h
Thus the proportion is solved
