Elevation vs. Distance The following graph, obtained from GPS data, shows the elevation of a hiker as a function of the distance d from the starting point of the trail. a. Find the slope of the secant line that passes through points A and B . Interpret your answer as an average rate of change over the interval 1 ≤ d ≤ 3. b. Repeat the procedure outlined in part (a) for the secant line that passes through points P and Q c. Notice that the elevation function is nearly constant over the segment of the trail from mile d = 4.5 to mile d = 5. Give a plausible explanation for the horizontal line segment.

World Population The figure shows the real and projected total population w, in billions, of the world forselected years t from 1950 through 2050.a. Write the equation of the line connecting thepoints (1950, 2.556) and (2050, 9.346).b. Does this line appear to be a reasonable fit to thedata points?c. Interpret the slope of this line as a rate of changeof the world population.d. Use the equation from part (a) to predict what theworld population will be in 2025.
Studs in a framed wall are placed 16” inches apart. A sloped wall presents a challenge in that the distance (L) between studs along the top plate is longer. If the top plate has a slope of 4/12, calculate distance L so that the stud layout can be marked on the top plate. Round your answer to the nearest 16th of an inch. Hint: First use the slope to calculate the rise for a 16” run.
