5. a tank initially contains 20 lb of salt dissolved in 200-gallon of water. starting at time t = 0, a solution containing 0.5 lb of salt per gallon enters the tank at a rate of 4 gallons per minute and the well-stirred solution is withdrawn at the same rate. (a) find the amount(in lb) of salt q in the solution as a function of t in minutes. (b) find the time at which the amount of salt in the tank reaches 50 lb. (c) find the quantity of salt in the solution as t + .

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
