Solve the problem.The Ideal Gas Law states that the pressure P of a gas obeys the function 
where n is the number of particles in the sample, T is the Kelvin temperature of the gas, V is the volume of the gas in liters, and k is the constant 1.38 × 10-23. Does the pressure have a local minimum along the line 
If so, what is the value of the
minimum pressure? Give reasons for your answer. Fill in the blank(s) with the appropriate word(s).
Solve the problem.An experimental model for a suspension bridge is built in the shape of a parabolic arch.
