Answer:

Below

Step-by-step explanation:

The polynomial has the following form:

● ax^2 + bx + c

Let x'and x" be the zeroes

● x x'= (1/5)

● x + x' = -2

When we khow the sum and the product of two numbers we can find them by solving the following quadratic equation:

● x^2 - Sx + p

S is the sum of those numbers and P is their product

● x^2 - (-2x) + 1/5

● x^2 + 2x + (1/5)

We will solve this equation by graphing it. The solutions are the intersection points with the x-axis

The solutions are approximatively -0.1 and - 1.9 ( pictures below)

● x'= -0.1

● x"= -1.9

The intial polynomial can be written in the factored form using the zeroes as:

● a ( x - x') (x- x")

● a (x -(-0.1)) ( x -(-1.9))

● a ( x+0.1) ( x+1.9)

The sum of the zeroes is -2 and their product is (1/5)

Assuming a = 1

● (x + 0.1) ( x +1.9)

● x^2 + 1.9x + 0.1x + 0.19

● x^2 + 2x + 0.19

Multiply by 100 to eliminate the decimal numbers

● 100x^2 + 200x + 19

Trigonometry

Alchen [17]

The area of the triangle PQR is 17.6 square units.

Explanation:

Given that the sides of the triangle are PQ = 12 and PR = 3 and $m\angle P = 78^{\circ}$

We need to determine the area of the triangle PQR

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

$\text {Area}=\frac{1}{2} qr \sin P$

Substituting the values, we get,

$\text {Area}=\frac{1}{2}(12)(3) \sin 78$

Simplifying, we have,

$\text {Area}=\frac{1}{2}(36)(0.98)$

Multiplying the terms, we have,

$\text {Area}=\frac{35.28}{2}$

Dividing, we get,

$\text {Area}=17.64$

Rounding off to the nearest tenth, we have,

$Area=17.6$

Thus, the area of the triangle PQR is 17.6 square units.

In the quotation in lines 61-64, George Will

The correct answer is option e) the extent to which a cloned person might differ from the original person.

In the quotation in lines 61-64, George Will primarily draws attention to the extent to which a cloned person might differ from the original person.

What is human(person) cloning?

Human cloning is the process of creating a genetically identical replica of a human (or clone).

The phrase is most commonly used to refer to artificial human cloning, or the replication of human cells and tissue. It does not relate to identical twins being conceived and delivered naturally.

The prospect of human cloning has sparked debate. Because of these ethical considerations, numerous countries have passed laws prohibiting human cloning.

Therapeutic cloning and reproductive cloning are the two most widely discussed kinds of human cloning. Therapeutic cloning would include cloning human cells for use in medicine and transplantation.

Context of lines 61-64

Satan is disoriented in a completely black pool of fire. Beelzebub, Satan's second-in-command, stands next to him. Satan addresses him and laments their current situation.

Satan advises them to flee the flaming lake and seek refuge on a distant beach. Beelzebub requests that Satan assemble his soldiers. Satan dons his armor and summons his armies to join him on land.

He addresses his troops and vows to continue his battle against God. The demons use their superhuman abilities to build Pandemonium, a huge temple for meetings.

EXPLANATION

The poet depicts the classic landscape of Hell in these verses. After their rebellion against God, Satan and his minions were hurled down from Heaven to Hell.

For nine days, they lay comatose in Hell's burning lake. When they regain consciousness, Satan notices that the location in which they are imprisoned is a horrifying, circular, and burning dungeon like a large furnace.

This analogy vividly conjures up the image of Hell's lake. Satan notes that there is fire but no light in Hell; it is complete darkness, complete darkness, without any residue, mixture, or prospect of light.

It will always be the blackness of darkness. The poet here employs the universal symbolism of light and dark to represent good and evil.

Satan, as Lucifer, was the brightest of all the angels before his fall; as he grows progressively more evil after his fall, he eventually loses all of his brightness.

Satan comes to the conclusion that the fires will never go out and the pain will never cease. In essence, the poet's description of Hell in these verses is a horrifying, scorching, and murky realm of sorrow and pain.
