9) a fighter plane, which can shoot a laser beam straight ahead, travels along the path r(t) = h5 − t, 21 − t 2 , 3 − t 3 /27i. show that there is precisely one time t at which the pilot can hit a target located at the origin

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
