In which number is the place value of the "5" equal to 1/10 of the place value of the "5" in 6.85?

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)

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)

The slope of the line passing through the points (2, 7) and (-4, 8) is
