Question

Can you explain why the answer for vector parametric equation is incorrect. Also can you explain how to determine limit of integration. Thank you

Find the line integral with respect to arc length
(5x + 3y)ds, where C is the line segment in the xy-plane with endpoints P = (5, 0) and
Q = (0,4).
(a) Find a vector parametric equation r(t) for the line segment C so that points P and Q correspond tot = 0 and t = 1, respectively.
7(t) = (5 – 5t,4t)
(b) Using the parametrization in part (a), the line integral with respect to arc length is
(5x + 3y)ds =
(25 – 13t) V41 dt
with limits of integration a = 0 and b = 1
(c) Evaluate the line integral with respect to arc length in part (b).
