Ventilation requirements Ventilation is an effective way to improve indoor air quality. In nonsmoking restaurants, air circulation requirements (in ft/min) are given by the func- tion V(x) = 35x, where x is the number of people in the dining area. (a) Determine the ventilation requirements for 23 people. (b) Find V-(x). Explain the significance of V-1. (c) Use V-1 to determine the maximum number of people that should be in a restaurant having a ventilation capa- bility of 2350 ft'/min.

The total fresh vegetables consumed per person per year can be modeled by V(t) = 0.2(t- 2)² + 64.8 where V(t) is the total fresh vegetables consumed per person in pounds per year t years since 2013. Find when the minimum intake of fresh vegetables per person occurred? {final answer will be just number only}
