I think it’s between the first and third one
Answer:
pay child support and I will answer
Sorry if I'm wrong
a = 10
this what I did
7 - 3 = 4 ÷ 0.4 = 10
Let be the line given by the vector equation
.
First, we use the director vectors of the lines L1 and L2 to get the
vector equation of the plane containing them, which we denote by . This is,
We observe that . Therefore, the vector equation of defines a plane and is a normal vector to
Finally, the vector equation for the wanted plane, which we denote by , is
Thus, if , then and since is parallel to , then it is perpendicular to .
