3. Is x^5 + x² + x? a polynomial? Explain why or why not.

**ANSWER:**

A polynomial is an algebraic expression of ordered addition, subtraction, and multiplication made up of variables, constants, and exponents.

Polynomials are made up of finite terms. Each term is an expression that contains one or more of the three elements they are made of variables, constants, or exponents.

In this case, for each term, the variable is x, the constant is 1, and the exponents are 5, 2, and 1, respectively.

This means that we have a sum of monomials, that is, that the expression is a polynomial.

A 8 letter Code word is selected. What is the probability that there are no repeated letters?

**Probability** of selecting eight letter word without repetition of letter** is **0.3016.

There are total 26 letters in English** alphabets**. A 8 letter Code word is selected. We have to take care of repetition of letters as be are not allowed to repeat the letters.

Any letter being chosen should have an equal probability of 1/26. So, we have a probability of 1 to get a **non-repeated** **letter** while choosing the first letter.

For first letter the probability is = 26/26

For second letter the probability is = 25/26

For third letter the probability is = 24/26

For fourth **letter** the probability is = 23/26

For 5th letter the probability is = 22/26

For 6th letter the probability is = 21/26

For 7th letter the probability is = 20/26

For 8th letter the probability is = 19/26

To get an **eight letter code** that has no repeated letters, all these events have to occur.

Probability of selecting eight letter word without repetition of letters = (26/26) (25/26) (24/26) (23/26) (22/26) (21/26) (20/26) (19/26)

Probability of selecting eight letter word without repetition of letters = 0.3016

So, 0.3016 is the **probability **of selecting eight letter word without repetition of letters.

The area of one surface of a cube is 19,600 sq. cm. If the cube is filled with water how many bottles of 4 litres each can be filled from it?

**686 bottles** of 4 liters each can be filled from this **cube. **

We can solve this problem by following a few steps.

As we know that** a cube has 6 surfaces** and each surface has a geometrical shape of a square. We also know that each side of a square is the same.

So, the **surface area of a square ≡ Side × Side. **

Let's assume the side as z

Now, the area of this square ≡ z × z = z²

∴ z² = 19600, as per the question.

We have to solve the equation, z² = 19600 Or, z = 140 ( by doing root both sides)

Now we know the side of the cube, then the volume of this cube is z³.

As, we know the **volume of a cube ≡ side × side × side**, as the height of a cube is also identical.

Volume of the cube = 140³ = 2,744,000 cc

**1000 cc is considered as 1 liter**. Therefore, this cube consists of, 2,744,000/1000 = 2744 liter of water.

Each bottle consists of **4 liters **of water. Then we can fill, 2744/4 = **686 **bottles of water.

a) x+4

b) a = 1, b = 10

**Step-by-step explanation:**

a) You can read the lenght of AB, which is 4 + x

b) The lenght of AD is 6+x

The area of the rectangle ABCD is lenght AB * lenght CD,

so (4+x)*(6+x) = 24 + 6x + 4x + x^2 = x^2 + 10x +24

Since this must equal 28, it follows that

x^2 + 10x + 24 = 28,

so 1*x^2 + 10x = 4

(note that 1*x^2 is just x^2)

so a = 1 and b = 10

Five rays share a common endpoint. Set up an equation to find the value of x.

The **equation** that can be set up is, 2x° + 3x° + 36.5° + 36.5° + 2x° = 360°.

The value of x is: x = 41.

What are Angles around a Point?Angles that are formed around an **endpoint **but several rays will have a sum of 360 degrees when each of the angles formed around the **endpoint **is added together.

The diagram shows the angles that are formed by the five rays at a common **endpoint**. The angles are, 2x°, 3x°, 36.5°, 36.5°, and 2x°.

The sum of all these angles formed will give us 360 degrees. Therefore, the **equation** that would be created to find the value of x would be written as:

2x° + 3x° + 36.5° + 36.5° + 2x° = 360° [**equation** set up to find x]

Combine like terms

7x° + 73° = 360°

Subtract 73 from each side

7x° + 73° - 73° = 360° - 73° [subtraction property of equality]

7x = 287

Divide both sides by 7:

7x/7 = 287/7 [division property of equality]

**Step-by-step explanation:**

Write an equation that represents the line.

Use exact numbers.

**Answer:**

**y = -2x -3**

**Step-by-step explanation:**

To write an equation we need two points that the line cuts through.

we then use the formula: Gradient = Rise/Run

the points chosen are (0,-3) and (1,-5)

Gradient = (-5--3)/(1-0)

= -2

to write the equation we need one known point, gradient and one unknown point say (x,y).

we therefore use the formula for gradient/slope

G = Rise/Run

-2 = y+3/x-0

-2x = y + 3

**y = -2x -3**

**Answer:**

y = - 2x - 3

**Step-by-step explanation:**

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (1, - 5) ← 2 points on the line

m = [tex]\frac{-5-(-3)}{1-0}[/tex] = [tex]\frac{-5+3}{1}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2
