Sketch the graph of the resulting equation, showing both sets of axes. 9x2+24xy+16y2+90x130y=024E25E26E27E28E29E30E31E32E33E34E35E36E37E38E39E40E41E42E43E44E45E46E47E48E49E50E51E52E53E54E55E56E57E58E59E60E61E62E63E64E65E66E67E68ESketch and describe the orientation of the curve given by the parametric equations x=2tandy=4t2+2,2t2.2ECPSketch the curve represented by each set of equations by eliminating the parameter. a. x=5cos and y=3sin,02 b. x=1+tan and y=2+2sec,/23/2Find a set of parametric equations to represent the graph of y=x2+2, using each parameter. a. t=x b. t=2xWrite parametric equations for a cycloid traced by a point P on a circle of radius a as the circle rolls along the x -axis given that P is at a maximum when x=0.1E2E3E4E5E6E7E8E9E10E11E12E13E14E15E16E17E18E19E20E21E22E23E24E25E26E27E28E29E30E31E32E33E34E35E36E37E38E39E40E41E42E43E44E45E46E47E48E49E50E51E52E53E54E55E56E57E58E59E60E61E62E63E64E65E66E67E68E69E70E71E72E73E74E75E76E77E78E79E80E81E82E83E84E85E86E87E88E89E90E91E92EPath of a Baseball The center field fence in a baseball stadium is 7 feet high and 408 feet from home plate. A baseball player hits a baseball at a point 3 feet above the ground. The ball leaves the bat at an angle of degrees with the horizontal at a speed of 100 miles per hour (see figure). (a) Write a set of parametric equations that model the path of the baseball. (See Exercises 91 and 92.) (b) Use a graphing utility to graph the path of the baseball when =15. Is the hit a home run? (c) Use the graphing utility to graph the path of the baseball when =23. Is the hit a home run? (d) Find the minimum angle required for the hit to be a home run.94E95E96E97E98E99E100E101E102E103E104E105E106E107E108E109E110EPlot each point given in polar coordinates. a.3,/4b.2,/3c.2,5/32ECP3ECP4ECP5ECP1E2E3E4E5E6E7E8E9E10E11E12E13E14E15E16E17E18E19E20E21E22E23E24E25E26E27E28E29E30E31E32E33E34E35E36E37E38E39E40E41E42E43E44E45E46E47E48E49E50E51E52E53E54E55E56E57E58E59E60E61E62E63E64E65E66E67E68E69E70E71E72E73E74E75E76E77E78EConverting a Polar Equation to Rectangular Form In Exercises 79-100, convert the polar equation to rectangular form. r=5Converting a Polar Equation to Rectangular Form In Exercises 79-100, convert the polar equation to rectangular form. r=781EConverting a Polar Equation to Rectangular Form In Exercises 79-100, convert the polar equation to rectangular form. =5/3Converting a Polar Equation to Rectangular Form In Exercises 79-100, convert the polar equation to rectangular form. =/2Converting a Polar Equation to Rectangular Form In Exercises 79-100, convert the polar equation to rectangular form. =3/285E86E87E88EConverting a Polar Equation to Rectangular Form In Exercises 79-100, convert the polar equation to rectangular form. r=2cosConverting a Polar Equation to Rectangular Form In Exercises 79-100, convert the polar equation to rectangular form. r=4sin91E92E93E94E95E96E97E98E99E100E101E102E103E104E105E106E107E108E109E110E111E112E113E114E115E1ECP2ECP3ECP4ECP5ECP6ECP1E2E
