The rate at which a tsunami approaches the coast of North Carolina is modeled by r=439t where r is rate and t is time. If the tsunami is approaching at 150 km/hr, how much time do we have to prepare?

the answer for your question is

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.

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
