If friction is ignored, the time t (in seconds) required for a block to slide down an inclined plane (see the figure) is given by the formula t = 2a gsin⁡θcos⁡θ, where a is the length (in feet) of the base and g≈32 feet per second per second is the acceleration due to gravity. How long does it take a block to slide down an inclined plane with base a = 90 feet when θ = 30∘? t = (Do not round until the final answer. Then round to two decimal places as needed.)

XYZ Moving Company has a new tool that consists of a heavy-duty ramp that connects the truck to the apartment buildings, so customers can slide their items directly into the truck without using the elevator or stairs. If friction is ignored, the time t (in seconds) required for an item to slide down the ramp is given by the function: t(θ) = 2a gsin⁡θcos⁡θ Where a is the distance from the building to the truck and g ≈ 32 feet per second per second is the acceleration due to gravity. How long would it take an object to slide from the balcony of an apartment to the truck if the distance between the building and the truck is a = 10 feet when:

The concentration of particulate matter (in parts per million) t hours after a factory ceases operation for the day, is given by the following formula, C(t). Find the average concentration for the period from t = 0 to t = 6. C(t) = 18 ln⁡(t+11) (t+11)2 The average concentration of particulate matter, for the time period from t = 0 to t = 6, is approximately parts per million. (Do not round until the final answer. Then round to four decimal places as needed.)
