A spherical helium balloon that is 8 feet in diameter can lift about 10 pounds. What does the diameter of a balloon need to be to lift a person who welghs 80 pounds?

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
