Question 49

Multiple Choice

Find a parametric representation for the part of the elliptic paraboloid x+y2+10z2=5x + y ^ { 2 } + 10 z ^ { 2 } = 5 that lies in front of the plane x=0x = 0 .


A) x=x,y=5x10z2,z=zx = x , y = \sqrt { 5 - x - 10 z ^ { 2 } } , z = z
B) x=5y210z2,y=y,z=y,y2+10z25x = 5 - y ^ { 2 } - 10 z ^ { 2 } , y = y , z = y , y ^ { 2 } + 10 z ^ { 2 } \leq 5
C) x=5y210z2,y=y,z=y,0y2+10z23x = 5 - y ^ { 2 } - 10 z ^ { 2 } , y = y , z = y , 0 \leq y ^ { 2 } + 10 z ^ { 2 } \leq 3
D) x=x,y=±5x10z2,z=zx = x , y = \pm \sqrt { 5 - x - 10 z ^ { 2 } } , z = z
E) x=5y210z2,y=y,z=y,y2+10z25x = 5 - y ^ { 2 } - 10 z ^ { 2 } , \mathrm { y } = y , z = y , y ^ { 2 } + 10 z ^ { 2 } \geq 5
