Question

Tolong bangett kak, nanti kalo ga bisa jawab aku gak boleh ikut ulangan :(

Answer 1

Vektor Ruang 3

K { 1, - 2, - 8 }

L {3 , - 4, 0 }

KM = - 3 ML

m- k = -3 (l - m)

m - k = - 3l + 3m

3l - k = 3m - m

3l - k = 2m

m = 1/2 ( l - k)

*

m = 1/2 { (3, - 4, 0 )  +  (1 , - 2, -8 ) ]

m = 1/2 { (3+1), (-4 - 2) , (0 -8) }

m = 1/2 ( 4, - 6, - 8)

m = (2 , - 3 , -4)

m  = 2i - 3j - 4k
