Question

Find a vector A and its magnitude with initial point P(1, 2, -1) and terminal point (3, 2, 2).

Answer 1

Answer:

will my height increase 5 inches? I am 5'7 nd goal us 6' age is 14 yr 4 months (yes i look a like a 17yro but i live in village and my genes are such hairy and big) my dad is only 5'9 but grandpa was 6'2.

will my height grow??

Answer 2

Answer:

Vector PQ = Final Point - Initial Point

Vector PQ = (3i,2j,2k)-(1i,2j,-1k)

Vector PQ = [(3i-1i) , (2j-2j) , (2k-(-1k))]

Vector PQ = (2i , 3k)

Magnitude of Vector PQ = $\sqrt{{2}^{2}+{3}^{2}}$

Magnitude of Vector PQ = $\sqrt{4+9}$

Magnitude of Vector PQ = $\sqrt{13}$

Hope it helps
