To find the position of the rocket ship after 10 seconds, we need to substitute t=10 into the parametric equations x(t) and y(t):
x(10) = 3(10) = 30
y(10) = 4(10)^2 + 1 = 4(100) + 1 = 401
Therefore, the rocket ship is at position (30, 401) after 10 seconds. So, the correct answer is C. (30,401).
x(10) = 3(10) = 30
y(10) = 4(10)^2 + 1 = 4(100) + 1 = 401
Therefore, the rocket ship is at position (30, 401) after 10 seconds. So, the correct answer is C. (30,401).
