Question

(b) Jane walks 100 feet in a direction of 20°, then 60 feet in a direction of 140°, then 80 feet in a direction of 260°, and another 40 feet in a direction of 300°. How far from her starting point is she, and what direction must she face to see the starting point? (c) Consider the line segment that starts at (2,3) and ends at (5,10) i. Write the parametric equation of this segment, using parameter t with 0 St3 1. ii. Now write this parametric equation in vector form ỹ-ที่1+b, still using t with 0 1. t ii. Normally we see m as slope, but the slope of this line segment is 5. Either describe why m is a slope, or why it is not
