What are the steps for using integer tiles to evaluate the expression 45 divided by 15? Start with 15 tiles and separate them into 3 same-sized groups. Start with 45 tiles and separate them into 15 same-sized groups. Assemble 45 groups of 3 tiles each. Assemble 45 groups of 15 tiles each.

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)
