Given that Jogging
is one of the few sports that has been consistently increasing over the
past few years and that the number of people jogging (in millions) from the
years 2000 to 2009 is given by the equation y=x+26,
where x is the number of years after 2000.
Part A
Use this equation or a graph of it to complete the ordered pair (8, ).
Given the equation: y = x + 26, when x = 8, then y = 8 + 26 = 34
Therefore, the complete ordered pair is (8, 34)
Part B
Write a sentence explaining the meaning of the answer to part a.
Given that x is the number of years after 2000, this means that x = 8 refers to 2008.
Therefore, the sentence describing the meaning of the answer to part a is 'The number of people jugging in the year 2008 equals 34 million.'
Part C
If this trend continues, how many joggers will there be in 2017?
For year 2017, x = 17 and the number of joggers in million is given by y = 17 + 26 = 43
Therefore, the number of joggers in 2017 is 43 million.
