Dani and jack went on a hike that started at a height of 4,000 feet. during the trek, they gained 500 feet in height per hour, h. its total elevation, e, therefore, can be represented by the equatione = 500h + 4,000.in the lines below, identify each part of the equation as a coefficient, variable or term.

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.
