At what points does the curve intersect the paraboloid (If an answer does not exist, enter DNE.) 15. 2/2 points | Previous Answers SCalcET7 13.1.030. At what points does the helix intersect the sphere (Round your answers to three decimal places. If an answer does not exist, enter DNE.) 16. 1/1 points | Previous Answers SCalcET7 13.1.041. Find a vector function, r ( t ), that represents the curve of intersection of the two surfaces. The cone and the plane r ( t ) = r ( t ) = t i + ( 4 t t 2 ) k z = x 2 + y ( x , y , z ) = (smaller t -value) ( x , y , z ) = (larger t -value) r ( t ) = sin t , cos t , t x 2 + y 2 + z 2 ( x , y , z ) = (smaller t -value) ( x , y , z ) = (larger t -value) z = x 2 + y 2 z = 7 2 ? = 5 ? + y

Find a vector function, r ( t ), that represents the curve of intersection of the two surfaces. The paraboloid and the parabolic cylinder r ( t ) = 18. 1/1 points | Previous Answers SCalcET7 13.1.047. If two objects travel through space along two different curves, it's often important to know whether they will collide. (Will a missile hit its moving target? Will two aircraft collide?) The curves might intersect, but we need to know whether the objects are in the same position at the same time . Suppose the trajectories of two particles are given by the vector functions for Find the values of t at which the particles collide. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)
