Name two pairs of parallel lines in the figure. a transversal intersecting two lines creates eight different angles: pairs of corresponding angles, pairs of alternate interior angles, and pairs of alternate exterior angles.

a.
2 . . 2 . .2
b.
4 . . 2 . . 2
c.
2 . . 2 . . 4
d.
4 . . 4 . . 4

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)
