Answer:

A. 5.0 * 10⁻⁹ J

Step-by-step explanation:

Q is charge.

ΔV is electric potential energy.

All we have to do is plug both values in.

PE = (1/2)(1.0 * 10⁻¹⁰)(100) = (1/2)(1.0* 10⁻⁸) = 5.0 * 10⁻⁹ J

A banner has a length of 10 feet and an area of 7 square feet. What is the width of the banner?
const2013 [10]

Answer:

the width is 0.7 feet

Step-by-step explanation:

Well we know that area = length * width. We know both the area and length, but not the width. Let's substitute the area and length in this equation, and substitute x for the width.

 

7 = 10 * x, or 7 = 10x

 

Now, solve for the width, or x, by dividing both sides by 10.

 

7(/10) = 10x(/10)

 

7/10 = x

 

Simplify 7/10 = 0.7

So the width of the banner is is 0.7 ft!

Someone help please ?
Rudik [331]

Answer:

8x^3y

Step-by-step explanation:

To evaluate or simplify expressions with exponents, we use exponent rules.  

1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.

2. When we multiply terms with the same bases, we add exponents.

3. When we divide terms with the same bases, we subtract exponents.

4. When we have a base to the exponent of 0, it is 1.

5. A negative exponent creates a fraction.

6. When we raise an exponent to an exponent, we multiply exponents.

7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.

We will use these rules to simplify.

\frac{(2yx^2)^4}{x^4y^42xy^{-1}}=\frac{2^4y^4x^{2*4}}{2x^{4+1}y^{4+-1}}= \frac{2^3y^4x^8}{x^5y^3}=8x^3y
