If the exchange rate between Argentina and Chile is based on their relative value to the US$, what is the exchange rate for Chilean Pesos versus Argentinean Pesos?

- "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."

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
