The curve C C\,C has parametric equations
x=3−2tt+1y=3t+1t+10≤t≤5 x = \frac{3 - 2t}{t + 1} \quad y = \frac{3t + 1}{t + 1} \quad 0 \leq t \leq 5 x=t+13−2ty=t+13t+10≤t≤5It is given that C C\,C is part of the straight line y=−25x+115\displaystyle y = -\frac{2}{5}x + \frac{11}{5}y=−52x+511 and that the length of the line segment is 5296\displaystyle \frac{5\sqrt{29}}{6}6529.
Verify that C C\,C is part of a straight line.
Verify that the length of the line segment is 5296\displaystyle \frac{5\sqrt{29}}{6}6529.
