Pole vault: The height of the winning pole vault in the early years of the modern Olympic Games can be modeled as a function of time by the formula

H = 0.05t + 3.3 .

 Here t is the number of years since 1900, and H is the winning height in meters. (One meter is 39.37 inches.)

 a. Calculate H (4) and explain in practical terms what your answer means.

 b. By how much did the height of the winning pole vault increase from 1900 to 1904? From 1904 to 1908?
