Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 50 gram sample of a substance that's
used to treat thyroid disorders has a k-
value of 0.1113.
Enter the correct swer
N- Noe
-kt
DONE
No - initial mass (at time t = 0)
N = mass at time t
k - a positive constant that depends on
the substance itself and on the units
used to measure time
t-time, in days

it is impossible.

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.
