 Find r(t)  given the following. \text { Find } \mathbf { r } ( t ) \text { given the following. } rt(t) =18t5j+6tk,r(0) =2i+18j\mathbf { r } ^ { t } ( t ) = 18 t ^ { 5 } \mathbf { j } + 6 t \mathbf { k } , \mathbf { r } ( 0 ) = 2 \mathbf { i } + 18 \mathbf { j }


A) r(t) =2i+(18+3t6) j+3t2k\mathbf { r } ( t ) = 2 \mathbf { i } + \left( 18 + 3 t ^ { 6 } \right) \mathbf { j } + 3 t ^ { 2 } \mathbf { k }
B) r(t) =2i+3t2j+(18+3t6) k\mathbf { r } ( t ) = 2 \mathbf { i } + 3 t ^ { 2 } \mathbf { j } + \left( 18 + 3 t ^ { 6 } \right) \mathbf { k }
C) r(t) =(18+3t6) j+3t2k\mathbf { r } ( t ) = \left( 18 + 3 t ^ { 6 } \right) \mathbf { j } + 3 t ^ { 2 } \mathbf { k }
D) r(t) =2i+(183t6) j3t2k\mathbf { r } ( t ) = 2 \mathbf { i } + \left( 18 - 3 t ^ { 6 } \right) \mathbf { j } - 3 t ^ { 2 } \mathbf { k }
E) r(t) =18i+(2+3t6) j+3t2k\mathbf { r } ( t ) = 18 \mathbf { i } + \left( 2 + 3 t ^ { 6 } \right) \mathbf { j } + 3 t ^ { 2 } \mathbf { k }
