Question

Determine the parametric equations of the path of a particle that travels the circle: (x - 4)2 + (y - 3)2 = 49 on a time interval of 0 <t< 21 : if the particle makes one full circle starting at the point (11,3) traveling counterclockwise X(t) = 4+7*cos(t) y(t) = 3+7*sin(t) You are correct. Your receipt no. is 163-9070 Previous Tries if the particle makes one full circle starting at the point (4, 10) traveling clockwise x( t ) = 4+7cos(t) y( t ) = 3-7sin(t) Submit Answer You have entered that answer before Incorrect. Tries 4/8 Previous Tries if the particle makes one half of a circle starting at the point (11, 3) traveling clockwise x( t ) = 4+7cos(t/2) y( t ) = 3+7sin(2) Submit Answer Incorrect. Tries 6/8 Previous Tries
