Determine which of the following is false. (a) 3 vectors in r^3 lie in the same plane, then they are l-d. (b) if s = {01, up} is l-i but {01, up, u} is l-d, then u e span s (c) if a subset of r", s = {01, up}, is l-i but {v1, up, u} is l-d for all u e r", then r" = span s. (d) s = {v1, up} is l-d if p > n. (e) none of these

i believe the correct answer is b.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

maybe i can

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
