(1 point) a tank contains 1060 l of pure water. a solution that contains 0.06 kg of sugar per liter enters the tank at the rate 9 l/min. the solution is mixed and drains from the tank at the same rate. (a) how much sugar is in the tank at the beginning? y(0)= 0kg (include units) (b) with s representing the amount of sugar (in kg) at time t (in minutes) write a differential equation which models this situation. s′=f(t,s)= 0.54-(9s/1060) . note: make sure you use a capital s, (and don't use s(t), it confuses the computer). don't enter units for this function. (c) find the amount of sugar (in kg) after t minutes.

Points (−3, 5) and (3, 5) on the coordinate grid below show the positions of two players on a tennis court: A coordinate plane is shown. There is a point at 3, 5 labeled Player 2. There is a point at negative 3, 5 labeled Player 1. Which statement best describes the relationship between the positions of the two players? Player 2's position is Player 1's position reflected across the y-axis; only the signs of the y-coordinates of Player 1 and Player 2 are different. Player 2's position is Player 1's position reflected across the x-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different. Player 2's position is Player 1's position reflected across the x-axis; only the signs of the y-coordinates of Player 1 and Player 2 are different. Player 2's position is Player 1's position reflected across the y-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.

The positions of two divers from the water's surface after a dive are shown:Yong: −15 feetMaurine: − 12 feetWhich inequality explains why Maurine is closer to the surface than Yong? Because −12 < −15, so −12 is closer to 0 than −15 Because −12 > −15, so −12 is closer to 0 than −15 Because −12 < −15, so −12 is farther from 0 than −15 Because −12 > −15, so −12 is farther from 0 than −15
