Answer:

Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic and strong forces.[1]

See below for the proof that the areas of the lune and the isosceles triangle are equal

<h3>How to prove the areas?</h3>

The area of the isosceles triangle is:

A_1 = \frac 12r^2\sin(\theta)

Where r represents the radius.

From the figure, we have:

\theta = 90

So, the equation becomes

A_1 = \frac 12r^2\sin(90)

Evaluate

A_1 = \frac 12r^2

Next, we calculate the length (L) of the chord as follows:

\sin(45) = \frac{\frac 12L}{r}

Multiply both sides by r

r\sin(45) = \frac 12L

Multiply by 2

L = 2r\sin(45)

This gives

L = 2r\times \frac{\sqrt 2}{2}

L = r\sqrt 2

The area of the semicircle is then calculated as:

A_2 = \frac 12 \pi (\frac{L}{2})^2

This gives

A_2 = \frac 12 \pi (\frac{r\sqrt 2}{2})^2

Evaluate the square

A_2 = \frac 12 \pi (\frac{2r^2}{4})

Divide

A_2 = \frac{\pi r^2}{4}

Next, calculate the area of the chord using

A_3 = \frac 12r^2(\theta - \sin(\theta))

Recall that:

\theta = 90

Convert to radians

\theta = \frac{\pi}{2}

So, we have:

A_3 = \frac 12r^2(\frac{\pi}{2} - \sin(\frac{\pi}{2}))

This gives

A_3 = \frac 12r^2(\frac{\pi}{2} - 1)

The area of the lune is then calculated as:

A = A_2 - A_3

This gives

A = \frac{\pi r^2}{4} -  \frac 12r^2(\frac{\pi}{2} - 1)

Expand

A = \frac{\pi r^2}{4} -  \frac{\pi r^2}{4} + \frac 12r^2

Evaluate the difference

A =  \frac 12r^2

Recall that the area of the isosceles triangle is

A_1 = \frac 12r^2

By comparison, we have:

A = A_1 = \frac 12r^2

This means that the areas of the lune and the isosceles triangle are equal

Nastasia [14]

Answer:

0

Step-by-step explanation:

-10 + 10

-10 and 10 are additive inverses, so when we add them, it is equal to zero

-10 + 10 = 0
