56. Let E(x, y, z) = tan-'(xy + 2z) + zex²-y² + z and let r(t) = (h(t), et²-2t, t²-3t+3) be a parametrization of a curve in space where h(t) is a differentiable function where h(2) = -1 and h'(2) = 4. (a) Find the value of the constant a such that the rate of change of E at the point (x, y, z) = (2,2, -1) in the direction of (x,-1,2) is 18/5. (b) Let ß represent the rate of change of E with respect to t along the path r(t) at t = 2. Find the value of the constant B.

Construction and building inspectors ensure that construction meets local and national buillding codes and ordinances, zoning regulations, and contract specifications. They spend considerable time inspecting worksites, alone or as part of a team. Most work full time during regular business hours. Many states and local jurisdictions require some type of license or certification. The median annual wage was $56,040 in May 2014.

What is the ramp's vertical distance (height)? inches State your response to the nearest 0. 1 Construction laws are very specific when it comes to access ramps for the disabled. Every vertical rise of 1 inch requires a horizontal run of at least 12 inches. Does the ramp above satisfy the requirement? O Yes O No
