A scale drawing of a square playground has a side length of 4 inches. The drawing has a scale of 1 in : 5 ft. Find the actual perimeter and area of the playground.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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.
