Let u1 =(2, 1), u2 =(1,1), v1 =(3,−2) and v2 = (−1,1); and let L be a linear operator on R2 whose matrix representation with respect to the ordered basis E = {u1, u2} is A = (2 1
3 2).
Find the matrix representing L with respect to the ordered basis F = {v1, v2}.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
