The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f (x )equalsStartFraction x
ankoles [38]

Answer:

The rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities are:

a) 0.52

b) 2.63

Step-by-step explanation:

The rate of change of a function at a given point P can be obtained by evaluating the 1st derivative of the function in P. Thus,

f(x)=\frac{x^2}{2(1-x)}

\frac{df(x)}{dx} = \frac{d(\frac{x^2}{2(1-x)})}{dx} \\\frac{df(x)}{dx}  =\frac{x}{1-x}  + \frac{x^2}{2(1-x)^2} \\\frac{df(x)}{dx} = -\frac{x(x-2)}{2(x-1)^2}

Now for we just need to evaluate in each of the given points

a) \frac{df(0.3)}{dx} =-\frac{0.3(0.3-2)}{2(0.3-1)^2}\\\boxed{\frac{df(0.3)}{dx} =0.520408 \approx 0.52}

b)\frac{df(0.6)}{dx} =-\frac{0.6(0.6-2)}{2(0.6-1)^2}\\\boxed{\frac{df(0.6)}{dx} = 2.625\approx 2.63}
