Considere as matrizes a, b e c, quadradas da mesma ordem. sabe-se wue a=b=c e que a11=x+3y; b11=4x+2y e c11= 10, sendo a11,b11 e c11 os elementos da primeira linha e primeira coluna das matrizes a, b e c, respectivamente. com essas informações, qual o valor de x. y?

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)
