Tisha and her academic team are working to go to state finals. they must have a certain number of points to advance. they have had three local matches and will attend a district match. district match points count for twice the number of points than local matches do. choose the equation that would tisha find how many points they need to earn in the district match, d, to advance.

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)
