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

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
