Answer:5i

Step-by-step explanation:

√(-25)=√(-1)×√(25) √(-1)=I √(25)=5

Therefore √(-1)×√(25)=i×5=5i

Answer:

5i and -5i.

Step-by-step explanation:

i^2 = -1.

5i * 5i

= 25 * i^2

= 25 * -1

= -25.

-5i * -5i

= 25 * i^2

= 25 * -1

= -25.

Hi, please help me with the answers for the following questions. For this type of assignment, you make your own algebraic expres

LenKa [72]

The quotient of a trinomial and monomial can be 9x² +2x + 1 while the product of the polynomials x² + 2x + 1 and 3x² - 1 is 3x⁴ + 6x³ + 2x² - 2x - 1

<h3>The quotient of a trinomial and monomial</h3>

Let the variable be x.

Trinomial are polynomials that have three terms, while monomials have a single term.

Using the above definition, we have:

Trinomial = 9x³ + 2x² + x

Monomial = x

The quotient of the above is represented as:

$\frac{9x^3 +2x^2 + x}{x}$

Evaluate the quotient

9x² +2x + 1

<h3>The product or quotient of polynomials</h3>

To do this, we make use of the following polynomials:

x² + 2x + 1 and 3x² - 1

The product is represented as:

(x² + 2x + 1) * (3x² - 1)

Expand

3x⁴ - x² + 6x³ - 2x + 3x² - 1

Evaluate the like terms

3x⁴ + 6x³ + 2x² - 2x - 1

Hence, the product of the polynomials x² + 2x + 1 and 3x² - 1 is 3x⁴ + 6x³ + 2x² - 2x - 1

How does the volume of a cylinder change if the radius is quadrupled and the height is reduced to a third of its original size?

KIM [24]

Answer:

the answer is 1/3 pie r2h

Step-by-step explanation:

The volume of a cylinder is given by πr²h where, r is the radius of the cylinder and h is the height of the cylinder.

Also r=d/2 , where d is the diameter of the cylinder.

Therefore if the diameter is halved, the radius also gets halved ,i.e., it becomes r/2. Therefore the new volume = π(r/2)²h

=π(r²/4)h

=(1/4) πr²h

Therefore the volume becomes one-fourth of the initial volume.

35 POINTS! PLEASE HELP MEEE!!! HURRY PLEASE IM RUNNING OUT OF TIME!!!!!!!!!!!!!!!!!

Answer:

<h2>CYLINDER</h2>

Surface Area = 471.2 cm^2

<h2>TRIANGULAR PRISM</h2>

Surface Area = 60.75 m^2

Step-by-step explanation:

<h2>CYLINDER</h2>

The surface area formula for a cylinder is π x diameter x (diameter / 2 + height), where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is π x radius x 2 x (radius + height). ( π =3.14 )

FORMULA:

π x 5 x 2 x 15

WORK:

π x 5 = 15.7

15.7 x 2 = 31.4

31.4 x 15 = 471

<h2>TRIANGULAR PRISM</h2>

The surface area formula for a triangular prism is 2 * (height x base / 2) + length x width1 + length x width2 + length x base.

FORMULA:

2 x (2.5 x 1.5/2) + (6 x 4) + (6 x 4) + (6 x 1.5)

WORK:

(2.5 x 1.5) = 3.75/2 = 1.875

1.875 x 2 = 3.75

(6 x 4) = 24

(6 x 1.5) = 9

3.75 + 24 + 24 + 9 = 60.75
