Cho hệ các vector U = {(1,2,5 ); (0, -1, -4);(2, 3, 6); (1, 0, -3} .

a. Tìm số chiều và một cơ sở W của không gian con sinh bởi hệ vector U .

b. Tìm tham số k để 2

u k = + (2,3, 1) là một tổ hợp tuyến tính của W , và suy ra [ ]W

u .

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

answer: the answer is ann

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
