8. A container holds 2 liters of liquid and is full, but unfortunately has a leak that will empty the container in 20 minutes. We can express the volume of liquid in the container as V(t) = 2t2 – 80t + 800. Using completing the square to solve, when will the container only have 0.5 liters left? Answer step-by-steps. 9. A tennis ball is thrown up into the air. Its height, h in metres, after t seconds, is given by the function h(t) = -4.9t2 + 19.6t + 2.1. Using completing the square, how high is the ball after 3 seconds? Please round your answer to two decimal places. Answer step-by-steps.
