- 9. The arch of a train tunnel is in the shape of a parabola. The maximum height of the tunnel is 20 m. If the origin of a grid is placed at one end of the arch where the tunnel contacts the road, the other point of contact with the road is 40 m away. Which quadratic function can be used to model the arch?6. The path of a diver under water after a dive is in the shape of a parabola that opens upward. Using the water surface as the x-axis, the x-intercepts that the diver makes are 1 m and 5 m from the edge of the pool. The maximum depth, d, in metres, of the diver under water is 2 m. Which quadratic equation models the path of the diver?In 1993, the sports league introduced a salary cap that limits the amount of money spent on players' salaries. The quadratic model y=0.2313x2+2.600x+35.17 approximates this cap in millions of dollars for the years 1993-2013, where x=0 represents 1993, x=1 represents 1994, and so on. Approximate the sports league salary cap in 2009. The approximate sports league salary cap in 2009 is $_____ million. (Round to the nearest tenth as needed.) According to the model, in what year did the salary cap reach 60 million dollars? According to themodel, in _____, the salary cap reached 60 million dollars. (Round down to the nearest year.)
