The partial factorization of xX-12 is modeled with algebra tiles.
Which unit tiles are needed to complete the
factorization?
O3 negative unit tiles
O3 positive unit tiles
O4 negative unit tiles
O4 positive unit tiles

step-by-step explanation:

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)

the correct answer is d

hope this
