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

step-by-step explanation:

it's 15

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
