A veterinarian knows that a 50-pound dog gets 0.5 milligram of a certain medicine, and that the number of milligrams, m. varies directly with the weight of the dog, w. The vet uses these steps to find the amount of medicine to give a 10-pound
dog.
In which step did the veterinarian make his first error?

Step 1, 2, 3, or 4

in total they made   333.74 your welcome : d

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.

i don't even know how to read that, ill try to do it if you translate it into english.
