Question 1 A contour map shows the level curves fox,y) = c for equally Spaced Values of c . When reading a contour map , keep in mind : - your altitude does not change when you hike along a level curve - your altitude increases or decreases by the spacing when you hike from one level curve to the next. - The spacing of the level curves indicates steepness. they are closer together where the graph is Steeper . The average rate of change from P to Q is the ratio altitude 4 horizontal Refer to the contour map below C -540 B 400 D horizontal scale i km * let spacing = 20 meters what is the change in elevation from A to B ? Estimate the average rate of change from A to C . Estimate the average rate of change from point iis to li and i .Question 2 A measure of how hot the weather feels to an average person is the apparent temperature index, I. A model for this index is I= 0.885T - 22. 4 H + 1. 21.TH - 0.541 where I is the apparent temperature in degrees Celsius, I is the air temperature and It is the relative humidity in decimals . ( a) find DI and dI aT when T= 30 and H= 0-80. ( which has a greater effect on I, air temperature or humidity ? Explain.540 B 500 1 140 400 D 1 km let spacing 20 meters
