Domain: x > –6; range: all real numbers are the domain and range of f (x).

What is domain and range ?

The range of values that can be plugged into a function is known as its domain. The x values for a function like f make up this set (x).

                              The collection of numbers that the function assumes is known as its range. After we enter an x value, the function outputs this sequence of values.

we need to remove all the values of x such that

x + 6 ≤ 0

Solving for x, we get

x ≤ -6

So the only values of x allowed are the ones that make the next inequality true:

x > -6.

Thus we can write the domain as:

D {x | x ∈ R | x > -6}

Where the second part, x ∈ R, is usually ignored, as we assume that x is a real number .

The length of the other leg of the triangle is 11.7 inches

Now, According to the question:

We have the right triangle

The length of the right triangle is 24 inches

The length of the hypotenuse is 26.7 inches

To find the length of the other leg of the triangle

We know that the Pythagorean theorem.

The Pythagorean theorem states that the sum of the squares of the two legs is equal to the hypotenuse squared.

Let the length of the other leg of the triangle be 'x'

According to the information:

[tex]24^2 + x^2 = 26.7^2[/tex]

576 + [tex]x^{2}[/tex] = 712.89

[tex]x^{2}[/tex] = 712.89 - 576

[tex]x^{2}[/tex] = 136.89

1) x² - x - 30 = 0 : (x - 5)(x + 6) = 0

2) x² - 10x = -21 : (x - 7)(x + 3) = 0

3) x²= 10x - 9 : (x - 3)(x + 3) = 0

4) x – 5x =0 : x = 0

5) 10x - 24 = x² : (x - 6)(x - 4) = 0

6) x² = -12x : (x + 6)(x - 2) = 0

What is the factor of the quadratic expression?

Factorization of quadratic equations is the part of finding the roots of a quadratic equation. Factoring quadratic equations means converting the given quadratic expression into the product of two linear factors.

1) x² - x - 30 = 0

To factor this quadratic expression, we can use the method of finding the two integers that multiply to give us the constant term (-30) and add to give us the coefficient of the x term (-1). The two integers that fit this criterion are -6 and 5, so we can factor the expression as:

(x - 5)(x + 6) = 0

2) x² - 10x = -21

To factor this quadratic expression, we can use the method of finding the two integers that multiply to give us the constant term (-21) and add to give us the coefficient of the x term (-10). The two integers that fit these criteria are -7 and 3, so we can factor the expression as:

(x - 7)(x + 3) = 0

3) x²= 10x - 9

To factor this quadratic expression, we can use the method of finding the two integers that multiply to give us the constant term (-9) and add to give us the coefficient of the x term (10). The two integers that fit this criteria are -3 and 3, so we can factor the expression as:

(x - 3)(x + 3) = 0

4) x – 5x =0

To solve this equation, we can first combine like terms to get:

-4x = 0

Then, we can divide both sides by -4 to get:

x = 0

5) 10x - 24 = x²

To solve this equation, we can first move the x² term to the left side and the constant term to the right side to get:

x² - 10x + 24 = 0

To factor this quadratic expression, we can use the method of finding the two integers that multiply to give us the constant term (24) and add to give us the coefficient of the x term (-10). The two integers that fit this criteria are -6 and 4, so we can factor the expression as:

(x - 6)(x - 4) = 0

6) x² = -12x

To solve this equation, we can first move the constant term to the right side to get:

x² + 12x = 0

To factor this quadratic expression, we can use the method of finding the two integers that multiply to give us the coefficient of the x term (12) and add to give us 0. The two integers that fit this criteria are -6 and 2, so we can factor the expression as:

(x + 6)(x - 2) = 0

Hence, the factor of the quadratic expression are:

1) x² - x - 30 = 0 : (x - 5)(x + 6) = 0

2) x² - 10x = -21 : (x - 7)(x + 3) = 0

3) x²= 10x - 9 : (x - 3)(x + 3) = 0

4) x – 5x =0 : x = 0

5) 10x - 24 = x² : (x - 6)(x - 4) = 0

The length of the line segment with endpoints P(2, 1, -4) and Q(-1, 5, 3) is 8.60 units

To find the length of a line segment with endpoints P(x1, y1, z1) and Q(x2, y2, z2) in three-dimensional space, we can use the distance formula:

length = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²)

Substituting the coordinates of P and Q into the formula, we get:

length = √((-1 - 2))²  + (5 - 1))²  + (3 - (-4)))² )

          = √((-3))²  + (4))²  + (7))² )

0.117 Or 11.7% chance of n should the player choose in order to maximize the probability of winning a prize.

The probability of precisely x successes on n further trials in an experiment with two potential outcomes is referred to as the binomial probability (commonly called a binomial experiment).

When a procedure is performed a certain number of times (for example, in a group of patients), the result for each patient can either be a success or a failure, the binomial distribution model enables us to calculate the probability of witnessing a defined number of "successes."

The probability of winning a prize remains the same for. n = 10 or n=20 or n = 100; the probabilities are the same.

Given that,

p = 0.5, So, q = 1 - 0.5 = 0.5.

If 70% of 'n' games are won then 30% of n games must be lost.

Let n = 10.

Therefore, P ( x = 3) = [tex]^{10}C_3p^7q^3[/tex]

or, P ( x = 3) = [tex]^{10}C_3(0.5)^7(0.5)^3[/tex]

or, P (x = 3) = 120×0.0078×0.125.

or, P (x = 3) = 0.117 Or 11.7% chance.

Now, Changing the value won't have any effect as all the 'n's are multiple of 10 and we'll have same probability.

b) The compound interest for the first period is $ 114.125 and the amount is $ 18,374.125

The compound interest for the second period is $ 114.83828125 and the amount after second period is $ 18,488.96

What is Compound Interest?

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

a)

Let the principal be P = amount after first period =  $ 402

Now , the rate of interest r = 6 %

The compound interest is calculated by compounding monthly

Now , the interest for the second period = ( PRT / 100 x 12 )

Substituting the values in the equation , we get

The interest for the second period = ( 402 x 6 x 1 ) / 1200

The interest for the second period = $ 2.01

The amount after the second period = amount after first period +  interest for the second period

The amount after the second period = 402 + 2.01

The amount after the second period = $ 404.01

b)

Let the principal be P = $ 18260

The rate of interest r = 2.5 %

The compound interest is calculated by compounding quarterly

Now , the interest for the first period = ( PRT / 4 x 100 )

Substituting the values in the equation , we get

The interest for the first period = ( 18260 x 2.5 ) / 400

The interest for the first period = 45650 / 400

The interest for the first period = $ 114.125

The amount for the first period = 18260 + 114.125

The amount for the first period = $ 18,374.125

Now , the principal for the second period = interest + amount of first period

The principal for the second period = $ 18,374.125

The rate of interest = 2.5 %

The interest for the second period = ( PRT / 4 x 100 )

Substituting the values in the equation , we get

The interest for the second period = ( 18374.125 x 2.5 ) / 400

The interest for the second period = 45935.3125 / 400

The interest for the second period = $ 114.83828125

The amount for the second period = 18,374.125+ 114.84

The amount for the second period = $ 18,488.96
