Notice: 10 K = 10,000 Meters Answer items1-3 below based on the information that Jim received about his three running friends. Use x as the number of minutes elapsed since the race began and y as the number of meters completed.
1. Use DESMOS to make a single scatter plot or multiple scatter plots showing the data for each runner.

Find a parametrization for the curve「and determine the work done on a particle moving along γ in r3 through the force field f: r^3--r^3'where f(x, y,z) = (1,-x, z) and (a) im (γ) is the line segment from (0,0,0) to (1,2,1) (b) im (γ) is the polygonal curve with successive vertices (1,0,0), (0,1,1), and (2,2,2) (c) im (γ) is the unit circle in the plane z = 1 with center (0,0,1) beginning and ending at (1,0,1), and starting towards (0,1,1)
