# Ahighway engineer wants to estimate the maximum number of cars that can safely travel on a particular road at a given speed. she assumes that each car is 14 feet long, travels at speed s, and follows the car in front of it at a safe distance for that speed. she finds that the number n of cars that can pass a given spot per minute is modeled by the function n(s)=86s14+14(s17)2 at what speed can the greatest number of cars travel safely on that road?

Titus works at a hotel. part of the job is to keep the complementary picture of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water as the shift progresses, he reports the level of the water every 10 minutes after two hours uses a regression calculator to compute an equation for the decrease in water his equation is w= -0.414t+129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
