Electrons and protons are particles in an aton with equal but opposite charges. Electrons have a negative charge and protos have
vredina [299]

Answer:

The total charge on atom is -2.

Step-by-step explanation:

We are given the following in the question:

Electrons have a negative charge.

Let this charge be represented by -1.

Protons have a positive charge. Let this charge be represented by +1.

An atom have 2 more electrons than protons.

Let x be the number of protons.

Then, the number of electrons are (x+2)

Total charge on atom =

=Charge on atom = Charge of protons + Charge of electrons

=(+1)(x) + (-1)(x+2)\\=x-x-2\\=-2

Thus, the total charge on atom is -2.

Which domain restrictions apply to the rational expression? x^2+4x+4 / x^2−4 Select each correct answer x≠−4 x≠−2 x≠0 x≠2 x≠4
Degger [83]
The correct answers are x≠2 and x≠(-2).

Domain restrictions are any points in the domain where the function will not have a value.  This basically means that it's a point where x won't work in the function.

For the numerator, any value will work for x.  We can have a value of 0 in the numerator, or a positive, negative, or decimal number.

However, the denominator cannot equal 0.  This is because a fraction bar represents division, and we cannot divide by 0.  The values that make the denominator 0 can be found by:

x²-4=0

Add 4 to both sides:
x²-4+4 = 0+4
x² = 4

Take the square root of both sides:
√x² = √4

x = 2 or x = -2.

Answer:

Fraction Form: \frac{2187}{4000000}

Decimal Form: 0.000547

Step-by-step explanation:

=\frac{5}{256} * \frac{3}{5}^1^2 / \frac{3}{5}^5

\frac{3}{5}^1^2/\frac{3}{5}^5=\frac{2187}{78125}

=\frac{5}{256}*\frac{2187}{78125}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}

\frac{5*2187}{256*78125}

\mathrm{Factor\:the\:number:\:}\:78125=5\cdot \:15625

=\frac{5*2187}{256*5*15625}

\mathrm{Cancel\:the\:common\:factor:}\:5

=\frac{2187}{256*15625}

\mathrm{Multiply\:the\:numbers:}\:256\cdot \:15625=4000000

\frac{2187}{4000000}
