The grade, g, of a road is defined as the distance it rises (or falls) to the distance it runs horizontally, usually expressed as a percentage. Consider a road with positive grade, g. Suppose that you begin driving on that road at an altitude a0. Complete parts (a) through (e). c. Apply your results in parts (a) and (b) to a road with a 5% grade and an initial altitude of 1 mile. Express your answer for the slope to four decimal places. a= + d (Round to four decimal places as needed.) d. For the road in part (c), what altitude will you reach after driving 10 miles along the road? miles (Round to three decimal places as needed.) e. For the road in part (c), how far along the road must you d
