Soccer A regulation soccer field has a rectangular penalty area that measures 132 feet ~J by 54 feet. The goal is 24 feet wide and centered along the back of the penalty area. Assume the goalkeeper can block a shot 6 feet to either side of their position for a total coverage of 12 feet. (Source: Federation lntemationale de Football Association)A penalty kick is taken from a comer of the penalty area at position A (see Figure 11). The goalkeeper stands 6 feet from the goalpost nearest the shooter and can thus block a shot anywhere between the middle of the goal and the nearest goalpost (segment CD). To score, the shooter must kick the ball within the angle CAE. Find the measure of this angle to the nearest tenth of a degree. 24ft Figure 11

Human Cannonball In Example 2 of Section 1.2, we found the equation ofthe path of the human cannonbalL At the 1997 Washington County Fair in Oregon, David Smith, Jr., The Bullet, was shot from a cannon. As a human cannonball, he reached a height of 70 feet before landing in a net 160 feet from the cannon. In that example we found the equation that describes his path is 7 y= 80)2 + 70 for 0 x:O:; 160 Graph this equation using the window o x:O:; 180, scale 20; 0:0:; y:o:; 80, scale = 10 Then zoom in on the curve near the origin until the graph has the appearance of a straight line. Use ITRACE Ito find the coordinates of any point on the graph. This point defines an approximate right triangle (Figure 15). Use the triangle to find the angle between the cannon and the horizontal. y Figure 15 Figure 16

Human Cannonball To get a better estimate of the angle described in Problem 73, we can use the table feature of your calculator. From Figure 15, we see that for any point (x, y) on the curve, (J = tan-1 (y/x). Define functions Yl andY2 as shown in Figure 16. Then set up your table so that you can input the following values of x: x 10,5, 1,0.5,0.1,0.01 Based on the results, what is the angle between the cannon and the horizontal?
