Consider the exponential function f(x)=13500×0.89^x which models the value of mikaylas scooter, where x represents the number of years since she purchased scooter

part a: is the value of of mikaylas scooter growing or decaying?

part b: what is the rate of growth or decay?

part c: what does 13500 represent?

Part a: decaying;

Part b: decays 11% each year( 100-89=11);

Part c:the initial value of the scooter ( money spent to buy the scooter)

- "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."
