IL The Hiker You are planning a 20-mile hike in the Cascades. The guidebook provides you with a chart, plotting elevation above the trailhead (in feet) as a function of the distance hiked (in miles). This plot is shown and is modeled by the function e(x)=125x²-6.25x¹. s 31-33. Using the graph of e(x), explain in words how the tangent lines to the graph relate to the difficulty of the 34-36. What can you say about the slope of the tangent line at the point of highest elevation on the graph? 37-39. Find the instantaneous rate of change of elevation as a function of x (distance hiked). Include units your answer. 40-42. Determine how far the hiker will have traveled when he reaches the highest point on the trail. teat 5000
