Katie is working on a blueprint for a fence she is designing. She will need to construct parallel lines to ensure that the second slat is parallel to the first. Which step will Katie need to do first to ensure that the second slat is parallel to the first slat in the diagram below?

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)
