True/false: Suppose f(r, y) and g(x, y) are continuous functions and f(x, y) > g(x,y) for all x, y in a region R. /| 25(z, y)dA - || 29(x, y)dA > 0

If X and y are continuous functions of t on an interval /, then the equations X = x(t) and y = y(t) are called and t is called the %3D Name the curves represented by a) x =t - 3 and y = t b) x = 4sin(t) and y = 3cos(t)|

2x'y+x?y? + 3xy³ 16x4 – ya if (x, y) # (0,0) Let f(x, y) = if (r, y) = (0,0) Determine the set of all points where f is continuous.

Consider a function z = F(u(s, t), v(s, t)) where F, u, and u are differentiable and u(8, 6) = -1, v(8, 6) = 2, u, (8, 6) = 5, u, (8, 6) = 9, vs(8, 6) = −3, v₁(8, 6) = 4, Fu(-1,2) = -4, and F(-1,2)= -10. Compute and when s = 8 and t = 6 dt
