1. Ryan was making a match stick square sequence as shown below. Use this sequence to answer the following questions: (a) How many squares connected together must be formed to use 28 matches?

___________________________

(b) How many squares connected together must be formed to use n matches?

___________________________

2 A ball rebounds one-half the height from which it is dropped. The ball is dropped from a height of 160 feet and keeps on bouncing. What height does it reach after the tenth bounce? (Do not round your answer.)

_____________________________

3. Use the information about the relationship between Amy's age and height in the table to answer parts (a) and (b).

 Age (years) 3 4 5 6 Height (cm) 100 110 120 130

(a) Write an equation that can be used to calculate Amy's height, h, when her age is n years.

______________________________________

(b) If Amy continues to grow at the same rate, what will her age be when she grows to a height of 195 cm?

______________________________________ A series of connected squares creates rectangles of different sizes. For example, the series of two connected squares at right creates a total of 3 rectangles. Use this information to answer questions 4 and 5.

4. How many rectangles are created by this series of 12 connected squares? ______________________________________

5. How many rectangles are created by a series of n connected squares?
