How would you do this problem? need asap you!

Short answer

9 you just read the graph. The distance traveled is pretty remarkable.

Discussion

1 hour = 60 minutes.

Read the graph until you hit the line when you start from 60 minutes and go vertically until you hit the line.  When you hit the line go horizontally and read what you see on the y axis. It should be 9.

There are other ways of solving this problem, but as long as you have the graph, you might just as well use it.

.

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)

i'm sure goog can you get that answer
