8 pts Question 11
Mark is stacking books on a shelf.
Each book is 1 inches in length.
How many books can Mark stack on a shelf that is 60 inches long?
1/40
O 40

the answer to your question is b.

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.
