Let r1,..., rp be vectors in Rn ,and let Q be an m*n matrix. Write the matrix [Q r1, ...,Qrp ]as a product of two matrices (neither of which is an identity matrix).

answer: 88

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
