Write each ratio in fraction form. Then write the percent equivalent.
12. 52 out of 208

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

most likely linear (proportionate)

step-by-step explanation:

as time increases heart rate increases

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.
