Answer:

Following are the solution to the given question:

Step-by-step explanation:

In question a:

$\to 16= 4^2$ is a perfect square.

$\to 125 = 5^3$ is not a perfect square

In question b:

$\to 20 = 2 \times 2 \times 5$ , not a perfect square.

$\to 25 = 5^2$ is a perfect square .

$\to 100 = 10^2$ is a perfect square .

$\to 125$ is not a perfect square, its nearest perfect square is $121 = 11^2 .$

$\to 144 = 12^2$ is a perfect square .

$\to 225 = 15^2$ is a perfect square .

$\to 10,000 = 100^2$ is a perfect square .

What is the surface area of the cylinder? 14ft length 9ft height

Alina [70]

Answer:

Step-by-step explanation:

I am assuming the top and bottom are closed.

Surface are = area of the curved side + 2 * area of the top

= 9* 14 * π + 2 * π * 7^2

= 126π + 98π

= 224π ft^2

Two models of cellular telephones, red and blue, are stored in boxes. One box weighs twelve pounds and contains four of the red

GenaCL600 [577]

First, make a equation in which r= red and b=blue.

So, since in the first box it has 4 red models and one blue model equaling 12,

the first equation looks like 4r+b=12.

The second equation looks like 2r+b=8.

What you would do is try and first solve for r by getting rid of b.

Since both equation has a positive b, you would make one equation have a negative b by multiplying the whole equation by -1.

-1*(2r+b=8)= -2r-b=-8

Add.

4r+b=12
+(-2r-b=-8)

2r=4
r=2

Then, you plug in 2 for the r for any of the original equations.

4(2)+b=12

8+b=12

b=4

or

2(2)+b=8

4+b=8
b=4

So, the red models weigh 2 pounds while the blue models weigh 4.

Which of the following equations is non-linear?

lakkis [162]

2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Step-by-step explanation:

Lets define a linear equation first.

A linear equation is an equation in which there is no variable with exponent greater than 1 or the degree of the equation is 1.

So,

x + 12 = -8x + 10 - 2y

The equation is a linear equation because the degree of the equation is 1.

x = 8x + 19 - 10y

The equation is a linear equation because the degree of the equation is 1.

2x + 6y = 14y - 19x^2 + 12

The equation involve a term with exponent 2 which makes the degree of the equation 2 making it a quadratic equation

2x + 13y + 14x - 7 = 16y - 3

The equation is a linear equation because the degree of the equation is 1.

Hence,

2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Keywords: Linear, quadratic

Can someone explain Scientific Notations? I don't understand them...

wlad13 [49]

Answer:

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.The primary reason for converting numbers into scientific notation is to make calculations with unusually large or small numbers less cumbersome.
