7) no 25n A) 1 D)-; for all x B) 5 10 Parametric equations and and a parameter interval for the motion of a particle in the xy-plane are given. Identify the particle's path by finding a Cartesian equation for it. Graph the Cartesian equation. Indicate the portion of the graph traced by the particle and the direction of motion. Make a table if necessary. Remeber-there is a direction to these curves. [MORE CHOICES ON NEXT PAGEL 8) from A) x2y2-25 (-5, 0) to (5, 0) FORMB

Answer 1

So the path gos from (-5,0) to (0,-5) to (5,0) ow = 25(cos2 t+ sin2 t = 25 So the cartesian equation of the path ofthe partile is the cercle x2 + y2 =25 The path is actually lower semi circle ofx® 2-25 n counterclockwise Hence the correct option is A.
