- Consider the following elevation function for a region of irregular terrain: z(x, y) = 1 x² + y² 25 Here, z is the elevation of the terrain over a point (x, y) with x and y being the horizontal coordinates. The region of interest lies between x = 0 and x = 5, and y 0 and y = 5. Your tasks are the following: = 1. Analyze how the elevation changes with respect to x and y. To find the elevation changes, calculate the partial derivatives of the elevation function z with respect to x and 2. Calculate the total volume of soil above the 0-level (z region of interest. = y. 0). To do so, integrate z(x, y) over the wholearrow_forwardA truck loaded with rocks weighs 14,260 lb.
