<PRE><B>Question 174293</B>
he hopes to be able to bend his knee a full 110 degrees in six weeks so he can play in the playoffs. after one week of physical therapy he can bend his knee at a 50 degree angle, after two weeks he can bend it 65 degrees and after three 78 degrees.will his knee be fully recovered in time for the playoffs?
-------------------
You have three points: (1,50),(2,65),(3,78)
-------------------
Making a regression analysis you might get the 
following equation: bend = 14*week + 36 1/3
---------------------------
bend(6 weeks) = 14*6 + 36 1/3
bend(6) = 120.3333333
------------------
His bend in the 6th week is predicted to be 120 1/3 degrees
He should be fully recovered in time for the playoffs.
