Answer:
16m
Step-by-step explanation:
4 x 2 = 8
8 x 2 = 16
Answer should be 1.85 x 10^18
no solutions → C
The 2 given lines are parallel and never intersect thus no solution
Answer:
Step-by-step explanation:
Since there exists a scalar
λ
λ
(namely
λ=a⋅b
λ=a⋅b
) such that
b=λa
b=λa
, the directions of the two vertices are the same (they are collinear). This implies that
|a⋅b|=|a||b|
|a⋅b|=|a||b|
.
So,
|a|=|(a⋅b)b|=|a||b||b|
|a|=|(a⋅b)b|=|a||b||b|
which implies that
|b|=1
|b|=1
