The deepest known spot in the oceans is the challenger deep in the mariana trench of the pacific ocean and is approximately 11,000 m below the surface. for a surface density of 1030 kg/m3 , a constant water temperature, and an isothermal bulk modulus of elasticity of 2.3 × 109 n/m2 , find the pressure at this depth. hint: the density will vary with depth in this case.

Find the vertex(use the completing the square method), findthe x- and y-intercepts, and sketch the graph offunction. y = 2x2 + 4x - 1
