Dear Daniel,

 You got 95 (out of 100) in the makeup exam

 
Here is what you got wrong:
#1: The parametric equation is x=t, y=0, z=0 or in vector notation (t,0,0) NOT just x=t:
-3 points

#7: You did it numerically, that is not a complete proof: -2 points

Since this is higher than 85 (that you got in midterm 1) 
your score is 95

 Best wishes,

  Dr. Z.
