/|\\ In 1920, the record for a certain race was 45.9 sec. In 1930, it was 45.7 sec. Let R(t) = the record in the race and t=the number of years since 1920. a) Find a linear function that ts the data. b) Use the function in (a) to predict the record in 2003 and in 2006. c) Find the year when the record will be 44.04 sec. ER Find a linear function that ts the data. R(t) = |:[ (Round to the nearest hundredth.) The predicted record for 2003 is [1 sec. (Round to the nearest hundredth.) The predicted record for 2006 is 1:] sec. (Round to the nearest hundredth.) The predicted record is 44.04 seconds in the year D. (Round to the nearest year.)
