Web4.1 Linear combination Let x1 = [2,−1,3]T and let x2 = [4,2,1]T, both vectors in the R3. We are interested in which other vectors in R3 we can get by just scaling these two vectors and … Web1 4 b 1 2 9 b 2 −1 −4 b 3 . Then the goal is to get this into reduced echelon form. To do so, subtract twice row 1 from row 2 and add row 1 to row 3, yielding: 1 4 b 1 0 1 b 2 −2b 1 0 0 b 3 +b 1 . The given equation is solvable only if b 3 +b 1 = 0, 3

Web1 2 3 +T 4 −5 6 = 3 −1 + −1 −11 = 2 −12 so the first condition of linearity appears to hold. Let’s prove it in general. Let u = u1 u2 u3 and v = v1 v2 v3 be arbitrary (that is, randomly selected) vectors in R3. Then T(u+v) = T u1 u2 u3 + v1 v2 v3 = T u1 +v1 u2 +v2 u3 +v3 = u1 +v1 +u2 +v2 (u2 +v2) −(u3 +v3) = u1 +u2 +v1 +v2 (u2 ...

Web1 day ago · Furthermore, we found that for low-VAF PZMs, deleteriousness decreased over time (odds ratio = 0.58, P = 1.4 × 10 −9) but remained constant for high-VAF PZMs (P = 0.15). These results suggest that mutations that appear deleterious on an evolutionary time scale may be benign or even beneficial to a growing fetus so long as the mutation ...
