match each exponential equation to its percent rate of change.

60% growth, 40% decay, 20% decay, 80% decay, 40% growth. In that order :)

Step-by-step explanation:

The number inside the parenthesis is always 1+a number. So for every .1 up or down, that's 10% growth or decay(up being growth, down being decay).

Step-by-step explanation:

A). In exponential equation , 1.6 is the common ratio which represents [(1 + 60% of 1) = 1.6] a growth of 60%.

B). In common ratio is 0.6 [(1 - 40% of 1)] which represents 40% decay.

C). In common ratio is 0.8 [(1 - 20% of 1)] which represents 20% decay.

D). In common ratio is 0.2 [(1 - 80% of 1)] which represents 80% decay.

E). In common ratio is 1.4 [(1 + 40% of 1)] which represents 40% growth.

- "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."
