Find exact coordinates of the centroid of the region bounded by the given curves. y = x + 56, y = x2 (X, V) - ( 5,34

Find the Area of the region bounded by given curves. For the complete solution, kindly write it on a sheet of paper for full visualization, thanks in advance.

Which surface below is shaped like a saddle? -x^2 + y^2 + z^2 = 1 z = -x^2 + y^2 O y^2 - x^2 = 1 z = -x^2 - y^2

Please explain each step with reasoning and definitions; I'm having a hard time understanding what I'm doing.
