Tennis balls are filled with nitrogen gas. 1.6% of the nitrogen gas has escaped from a particular ball after 10 hits. a) How much gas is left after a game that had 25 hits of the ball? b) The ball is considered too soft when the gas is at 75% of its original amount. How many hits are required before the ball is too soft? c) At what rate is the nitrogen gas escaping after 6 hits?(T 4 Marks + C 2 Mark) 1: 31 The tangents to the function .'P - sinx at x - 3 and x - T and the x-axis form a triangle. Determine the exact area of the triangle. Express your answer in terms of a. (Note: Draw a diagram indicating the area. Approximate sketch will do.)
