A barrel starts with 6 cups of water in it. During a heavy rainstorm, the amount of water in the barrel doubles every minute. A) What is the domain and the range of this scenario?

B) Write an exponential function for this scenario.

C) How many cups of water are in the barrel after 7 minutes?

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

- "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."

what is the model?
