Acommon inhabitant of human intestines is the bacterium escherichia coli. a cell of this bacterium in a nutrient-broth medium divides into two cells every 20 minutes. the initial population of a culture is 57 cells.
(a) find the relative growth rate. (assume t is measured in hours.)
k = ln(8)
(b) find an expression for the number of cells after t hours.
p(t) = 57(8)^t
(c) find the number of cells after 8 hours.
956,301,312 cells.
(d) find the rate of growth after 8 hours. (round your answer to three decimal places.)
cells per hour
(e) when will the population reach 20,000 cells? (round your answer to two decimal places.)

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

did you get the answer yet?
