For a system of vectors U = {(1,2,9 ); (2,3, 1);(0,-1,1-9);(2,3,10);(1,0,2-9) } . a. Find the number of dimensions and a basis W of the subspace generated by the vector system U .

b. Find the parameter k so that u = (2,3,k3+1) is a linear combination of W , and deduce [ u]W .

step-by-step explanation:

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
