What is the square root of x^6 over y^4

Alinara [238K]

$\sqrt\frac{x^6}{y^4}=\frac{\sqrt{x^6}}{\sqrt{y^4}}=\frac{\sqrt{x^{3\cdot2}}}{\sqrt{y^{2\cdot2}}}=\frac{\left(\sqrt{x^2}\right)^3}{\left(\sqrt{y^2}\right)^2}=\frac{|x|^3}{|y|^2}=\frac{|x|^3}{y^2}\\\\\\\\y\neq0$

That's the question ??

Oksanka [162]

Step-by-step explanation:

Before we answer, the area of a Circle given it radius is

$a = \pi r {}^{2}$

The area of a circle given it diameter is

$a = \pi( \frac{d}{2} ) {}^{2}$

So let answers question 1-4.

1. The area is

$1024\pi$

2. The area is

$576\pi$

3.

$1.225\pi$

4.

$309.76\pi$

For the 5th problem, circumference is

$\pi \times d$

where d is the diameter and

$2\pi r$

where r is the radius.

A circumference of 100 m means the radius is 50 because

$2\pi \times r = 100\pi$

$r = 50$

So this means the area is

$2500 {\pi}$

Imagine that you are planning to estimate the price of the average book at your college bookstore. The bookstore carries 13,000

mafiozo [28]

Answer: "13,000 books" represents the population.

"200" books represents the sample.

Step-by-step explanation:

A population is the term that denotes a whole large possible group of individuals, objects, events or measurements.
A subset of population is known as ample.
When population is too large to the researcher , then it uses sample to represent the entire population.

Here, "13,000 books" represents the population.

"200" books represents the sample which is a subset of 13,000 books.
