Un tren de pasajeros parte de la estación 1.2 horas después que parte un tren de carga. El tren de pasajeros viaja 18 millas por hora más rápido que el de carga, y ambos transitan en vías paralelas. los trenes viajan en la misma dirección y estarán en el mismo punto tres horas después de la salida del tren de pasajero. Calcule la velocidad de cada tren.

answer: can you give the

step-by-step explanation:

ur right ive taken the test

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
