Pressure measurements are taken at certain points behind an airfoil over time. These data best fit the curve y = 6 cos x − 1.5 sin x from x = 0 to 6 s. Use four iterations of the golden-search method to find the minimum pressure. Set xl = 2 and xu = 4.

Fa bus driver leaves her first stop by 7: 00 a.m., her route will take less than 37 minutes. if she leaves after 7: 00 a.m., she estimates that the same route will take no less than 42 minutes. which inequality represents the time it takes to drive the route, r?
