The equation, y = 10(1.0605)x, represents the winning prize money, in thousands, for first place in the Indianapolis 500 auto race, x represents the number of years after 1911, the first year. What is the value for 1911 (x = 0)? This is the prize money, in thousands. For instance, if you got 23, this represents $23,000. $10,605 $10,000 c. $0 The equation, y = 10(1.0605)x , represents the winning prize money, in thousands, for first place in the Indianapolis 500 auto race, x represents the number of years after 1911, the first year. What is the amount of prize money in 1961 ? Use x = 50, as it is 50 years after 1911. Round to the nearest whole number and add three zeros to the end. For instance, if you get an answer like 142.8, this rounds to 143, and add three zeros to get $143,000. $139,000 $530,000 $30,000 The table below represents the ordered pairs when the first four years are substituted into the equation y = 10(1.0605)x. They are rounded to the nearest whole number. Which one is incorrect: 1,2,3, or 4? 1 2 3 4 The equation, y = 19(1.057)x , represents book sales in billions of dollars since 1990. x represents the number of years after 1990. How many billions of dollars of books were sold in 1990? Use x = 0 and round the answer to the nearest whole number. $18 billion $19 billion $20 billion This is the table for the billions of dollars in book sales for the first four years after 1990, using the equation y = 19(1.057)X. They have been rounded to the nearest whole number. 1 2 3 4 If the equation, y = 19(1.057)x, predicts correctly, what will be the billions of dollars in book sales for 2010? Use x = 20 as 2010 is 20 years after 1990. Express the answer rounded to the nearest whole number. $58 billion $402 billion $21 billion Mark is in training for a marathon race. He has been training by running 10 miles each day. He will be increasing his running by this weekly formula: y = 10(1.1 )x. What is the value if x = 0? 0 miles 10 miles 11 miles The table below represents the amounts Mark ran in the first four weeks after he started increasing his distance by the formula, y = 10(1.1 )x , rounded to the nearest mile. Which of the values is incorrect? 11 12 14 15 Using the formula, y = 10(1.1 )x, what distance, in miles, will Mark be running in 10 weeks? Round to the nearest mile. 20 24 26 Compute the distance Mark will run if he continues using the formula, y = 10(1.1 )x, for 52 weeks (one year). Does this distance seem reasonable? yes no
