Fpr brainliest this question confuesd !

which number is the best approximation for 47√−23√ ?

a.)0.9

b.)2.9

c.)7.0

d.)13.8

the correct answer is 7.0

Step-by-step explanation: i used the wrong answer from above and they made me get the answer wrong so afterwards teh test i checked to see what the real answer was and it said it was 7.0

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

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.
