All vectors are in rn. check the true statements below:

a. for any scalar c, u* (cv) = c(u*v).

b. for a square matrix a, vectors in col a are orthogonal to vectors in nul a.

c. if vectors v1; : : : ; vp span a subspace w and if x is orthogonal to each vj for j = 1; : : : ; p, then x is in w(

d. if the distance from u to v is equal to the distance from u to -v, then u and v are orthogonal.

e. v*v =llvll^ 2

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

step-by-step explanation:

hope my answer has you!

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
