A hiker is descending a mountain at an average rate of 0.01 mile in elevation for every 1 mile of hiking, as shown in the diagram below. which expression represents the measure of the angle of depression (x)?

What is the difference between regular convex and concave polygons

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
