A recipe for pizza crust calls for cups of flour. This amount of flour will make a pizza crust with an area of 200 square inches. Mr. Jason uses this recipe to make a pizza crust with an area of 400 square inches. Since he needs to double the recipe to get a 400 square inch crust, how many cups of flour will he need to use. Explain your answer.

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)
