Given that vector p=i+2j-2k and q=2i-j+2k, find two vectors m and m satisfying the condition;
1 answer:
9514 1404 393
Answer:
Step-by-step explanation:
There are <em>an infinite number of possibilities</em>. Any vector whose dot-product with p is zero will be perpendicular to p.
Let m = 0i +1j +ak. Then we require ...
m·p = 0 = 0×1 +1×2 +a(-2) ⇒ 0 = 2 -2a ⇒ a = 1
m = 0i +1j +1k
__
Let n = 2i +0j +bk
n·p = 0 = 2×1 +0×2 +b(-2) ⇒ 2 -2b = 0 ⇒ b = 1
n = 2i +0j +1k

yes they are proportional
Step-by-step explanation:
|| represents the absolute value function:
|x| = x when x >= 0,
|x| = -x when x < 0.
Therefore (-8) * |2| = (-8) * 2 = -16. (A)
