(1 point) a tank contains 2780 l of pure water. solution that contains 0.05 kg of sugar per liter enters the tank at the rate 3 l/min, and is thoroughly mixed into it. the new solution drains out of the tank at the same rate. (a) how much sugar is in the tank at the begining? y(0) = 0 (kg) (b) find the amount of sugar after t minutes y(t) = (kg) (c) ast becomes large, what value is y(t) approaching ? in other words, calculate the following limit. lim y(t) = (kg)

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour. valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house. which graph correctly represents valerie's distance from her house after her coffee break?
