IN For r(t) = (2t, t2, 1-t), find T, N and B.

v1 =[ 2 5 1 ] , v2 =[ − 3 1 − 1 ] , b =[ 11 19 5 ] Show that b is in Span{v1,v2}. Express b as a linear combination of v1 and v2.

6. Find the foci for (a) (c) (x-6)² 9 (y-7)² + 25 - F₁ = (6, 11) and F₂ = (6,3) F₁ = (-6, 11) and F₂ = (6,3) 1 (b) (d) F₁ = (6, 12) and F₂ = (6,2) F₁ = (11,7) and F₂ = (1,7)
