A company spends x hundred dollars on an advertising campaign. The amount of money in sales S ( x ) (in $1000) for the 4-month period after the advertising campaign can be modeled by S ( x ) = 5 + 7 ln ( x + 1 ) If the sales total $19, 100, how much was spent on advertising? Round to the nearest dollar.

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
