A teacher asked has three students, Tom, Helen and Sandy to complete 200 exercises. The ratio of the exercises completed by Tom to the exercises completed by Helen to the exercises completed by Sandy is 3:3:4. Tom receives 8points for each exercise. If the three students altogether receive 1240 points, how many points does Helen receive for a completed exercise?

i can answer this question sweetie!

step-by-step explanation:

8(1/6)

step-by-step explain:

49/6= 48

8 (1/6)

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.
