question 111

Multiple Choice

Find parametric equations for the tangent line to the curve with parametric equations $x = 9 t$ , $y = 7 t ^ { 2 } , z = 4 t ^ { 3 }$ at the point with $t = 1$ . Select the correct answer.

• A) \(x = 9 + 9 t , y = 7 + 14 t , z = 4 + 12 t\)
• B) \(x = 9 + 9 t , y = 7 + 7 t , z = 4 + 4 t\)
• C) \(x = 1 + 9 t , y = 1 + 7 t , z = 1 + 4 t\)
• D) \(x = 1 + 9 t , y = 1 + 14 t , z = 1 + 12 t\)
