Let the vector system U = {(1,2, 9); (0,-1,-8);(2,3,10);(1,0,-7)} a. Find the number of dimensions and a basis W of the subspace generated by the vector system U .
b. Find the parameter x so that u=(2,3,+1) is a linear combination of W , and derive [U]w.

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
