someone plz help me....

In 1920 the record for a certain race was 46.6 sec. In 1950 it was 46.0 sec. let r(t)= the record in the race and t= the number of years since 1920.

(a) find a linear function that fits the data r(t)= (round to the nearest hundredth)

(b)use the function in (a)to predict the record in 2003 and in 2006.What is the predited record for 2003 and 2006 roun to the neareat tenth.

(c) In what year will the predicted record be 44.7 seconds?

  1. Have you provided all information. I would be extremely surprised to find that you are asked the questions you provided based solely on 2 points of data (1920 and 1950). Is there more data?
