Given that vector p=i+2j-2k and q=2i-j+2k, find two vectors m and m satisfying the condition;

Answer:

m = j +k
n = 2i +k

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

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

4x - 5y = 21

<em>y</em> = -4

<u>Step 2: Solve for </u><em><u>x</u></em>

Substitute in <em>y</em>: 4x - 5(-4) = 21
Multiply: 4x + 20 = 21
[Subtraction Property of Equality] Subtract 20 on both sides: 4x = 1
[Division Property of Equality] Divide 4 on both sides: x = 1/4
