Tolong jawab nomor 2 ya, pake cara, terima kasih

VEKTOR

==> PERBANDINGAN <==

M = (3×P + 1×Q)/(3+1) = 1/4×(3(4,9,-8) + 1(-4,-3,0))
M = 1/4 ×((12,27,-24) + (-4,-3,0))
M = 1/4 × (8, 24, -24)
M = (2, 6, -6)

MQ = Q-M = (-4,-3,0)-(2,6,-6) = (-6, -9, 6)

panjang MQ
= akar((-6)^2 + (-9)^2 + 6^2)
= akar(36+81+36)
= akar(153)

Jwb. e

P(4,9,-8) Q(-4,-3,0)
PM : MQ = 1:3
M=
(4×3+(-4×1))×1/4=(12-4)×1/4=8×1/4=2
(9×3+(-3×1))×1/4=(27-3)×1/4=24×1/4=6
(-8×3+(0×1))×1/4=(-24+0)×1/4=(-24)×1/4=(-6)
MQ = Q - M
= -4-2= -6
-3-6= -9
0-(-6)= 6
Jadi panjang MQ=
akar [(-6)^2+(-9)^2+6^2]
akar (36+81+36)
akar 153
