How many distinguishable 7 letter "words" can be formed using the letters in ALABAMA?

ALABAMA has seven letters

Step-by-step explanation:

so we will start at 7! Counting the number of A's in the word we have 4 A's and so we will divide it by 4!

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.
