Fiona started her study of bacteria growth with 1,000 bacteria in a petri dish. after 1 hour, the count was increased to 1,800. after 2 hours, the count was 3,240. after the third hour showed a count of 5,832, fiona wrote an equation to represent the exponential growth of the bacteria. what exponential growth function did fiona write? f(x) =

f (x )=1000 (1.8)x

:)

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
