The growth of a population of bacteria can be modeled by the exponential function P(t) = 500 (2)tThe graph models the population of the bacteria colony P(t) as a function of the time, t, that has passed.

What was the average rate of change for the first four weeks of population growth? [_] bacteria per week

JustSaiyan:

I am not that great at Math, you will want @Vocaloid when she gets on, when she has time.

Average rate of change is just the slope. So what are the coordinates of the first week and the fourth week? And then use the slope formula to find it. :)

nikkixmarie:

is it 1000

Show your work

nikkixmarie:

i did 500 times 2t

nikkixmarie:

got 1000t

TheSmartOne:

That's not how you find the slope of two points. Also your equation is 500(2)^t

nikkixmarie:

i dont know how to do this i gotta hurry im in class rn

TheSmartOne:

What are the two points when x=1 and when x=4 The formula is Slope is (y2-y1)/(x2-x1)
