Answer:
appreciated; depreciated
Explanation:
The dollar appreciates when there is an increase in the value of the dollar compared to others. In 2009 $1 U.S dollar could buy $0.89 Canadian dollars. Then, in 2010 $1 U.S dollar could buy $0.96 Canadian dollars. Therefore, the U.S dollar appreciated because $1 U.S dollar can buy more Canadian dollars.
The opposite happened with the exchange rate between the U.S dollar and the euro. From 2009 to 2010 the exchange rate decreased from 83.8 to 76.9. Then the U.S dollar depreciated: $1 U.S dollar can buy less euros.
