Answer:

Properties of a rhombus used to solve the following

Opposite angles are congruent
Diagonals are angle bisectors
Diagonals are perpendicular to each other
Adjacent angles are supplementary

(30)

∠2 = ∠3 = ∠5 = 27°
∠1 = ∠4 = 180° - (2*27°) = 126°

(31)

∠4 = 70°
∠1 = ∠2 = ∠3 = ∠5 = 1/2(180° - 70°) = 1/2(110°) = 55°

(32)

∠1 = ∠2 = ∠5 = 90° - 26° = 64°
∠3 = 26°
∠4 = 90°

Thallium-210 has a half-life of 1.32 minutes. Find an equation for the percent of Thallium-210 sample that remains after t minut

Lady bird [3.3K]

Answer:

p(t) = 100%·2^(-t/1.32)

Step-by-step explanation:

The equation for exponential decay is ...

(remaining amount) = (initial amount)·2^(-t/(half-life))

Here, we can represent the percentage remaining by p(t) and the initial amount by 100%. Then, for a half-life of 1.32 minutes, the amount remaining is ...

p(t) = 100%·2^(-t/1.32) . . . . . where t is in minutes

_____

Alternate functional forms are possible, such as ...

p(t) = 100%·e^(-0.525112t)

p(t) = 100%·0.591489^t
