Ahiker walks up and down a hill. the hill’s cross section can be modeled by the function y = – 3/4|x – 300| + 400 where x and y are measured in feet and d: [0, 600]. how far does the hiker walk?

Find the value of 1715⋅211.though these numbers aren't quite as nice as the ones from the example or the previous part, the procedure is the same, so this is really no more difficult. give the numerator followed by the denominator, separated by a comma.

Name the most appropriate metric unit for each measurement like the mass of cow

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.
