Find a basis for the column space of a. a = 1 −1 3 5 2 1 0 1 −2 −1 −1 1 find a basis for the null space of at for the given matrix. verify that every vector in col(a) is orthogonal to every vector in null(at).

what do you need me to answer?

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

do have an equation or graph or
