Answer:

[tex]g(x)=-4\sqrt{\dfrac{x}{5}}-6[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=4\sqrt{x}+1[/tex]

1.  Horizontal stretch

[tex]f\left(\dfrac{1}{a}x\right) \implies f(x) \: \textsf{stretched parallel to the $x$-axis (horizontally) by a factor of $a$}.[/tex]

Therefore, if f(x) is horizontally stretched by a factor of 5:

[tex]\implies f\left(\dfrac{1}{5}x\right)=4\sqrt{\dfrac{x}{5}}+1[/tex]

2.  Reflection across the x-axis

[tex]-f(x)\implies f(x) \: \textsf{reflected in the $x$-axis}.[/tex]

Therefore, if f(x/5) is reflected in the x-axis:

[tex]\begin{aligned}\implies -f\left(\dfrac{1}{5}x\right)&=-\left(4\sqrt{\dfrac{x}{5}}+1\right)\\\\&=-4\sqrt{\dfrac{x}{5}}-1 \end{aligned}[/tex]

3.  Translation

[tex]f(x)-a \implies f(x) \: \textsf{translated $a$ units down}[/tex]

Therefore, if -f(x/5) is translated 5 units down:

[tex]\begin{aligned}\implies -f\left(\dfrac{1}{5}x\right)-5&=-4\sqrt{\dfrac{x}{5}}-1 -5\\\\&=-4\sqrt{\dfrac{x}{5}}-6\end{aligned}[/tex]

Therefore:

[tex]g(x)=-4\sqrt{\dfrac{x}{5}}-6[/tex]

The required difference is equal to 25x/42

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

Given here: Alton shoveled snow on 5/6 of his driveway before lunch. Then he shoveled 2/7 of it after lunch.

Let the total snow quantity be x then we have

Before lunch as = 5/6×x

                           =5x/6

After lunch = 5x/6 × 2/7

                   =5x/21

∴ Difference = 5x/6 - 5x/21

                     =35x-10x / 42

                     = 25x/42

Hence, The required difference is equal to 25x/42

Answer:

We can use the formula for the area of a circle and the information provided to find the approximate area of the circle.

The formula for the area of a circle is A = πr², where r is the radius of the circle.

We know that the distance from the center of the circle to the chord AB is 6 and the length of the chord AB is 10.

We can use the Pythagorean theorem to find the radius of the circle.

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

So, we can use this theorem to find the radius of the circle as follows:

r² = (length of the chord /2)² + (distance of the chord to the center)²

r² = (10/2)² + 6²

r² = 25 + 36

r² = 61

r ≈ 7.8

Now that we know the radius of the circle, we can use the formula for the area of a circle to find the area of the circle:

A = πr²

A ≈ π (7.8)²

A ≈ 191.8

The approximate area of the circle is 192 square units.

Using the provided conditions and values, This is solved with the concept of word problem, The answer is first, second and third aircrafts have 576,512 and 864 seats.

A word problem in mathematics is a problem that is written in natural language (i.e., words) rather than in mathematical notation. It presents a real-world scenario that requires the use of mathematical concepts and skills to solve. Word problems often involve finding unknown quantities based on given information, and they can be challenging because they require students to understand the problem and translate it into mathematical equations or formulas. They are often used in primary and secondary education to help students apply their math skills to real-world situations and develop critical thinking skills.

A mathematical expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that represents a mathematical statement or equation. Mathematical expressions can be evaluated to find a numerical value. They can also be simplified by applying the order of operations (PEMDAS) to combine like terms or to remove unnecessary parentheses. Additionally, mathematical expressions can also be used to represent the relationship between different variables.

Let x be the number of seats on the second aircraft. Then, the first aircraft has x+64 seats and the third aircraft has 2x-152 seats.

We know that the total number of seats for all three aircraft is 1900, so we can set up the following equation:

x + (x+64) + (2x-152) = 1900

Solving this equation gives us x = 512, which means the second aircraft has 512 seats. We can then use this information to find the number of seats for the other two aircraft:

First aircraft: 512 + 64 = 576 seats

Third aircraft: 2(512) - 152 = 864 seats.

ES = 10.63 units

The length of the line segment connecting any two points represents the distance between them. There is just one line that connects the two places. Therefore, by measuring the length of the line segment that connects the two sites, the distance between them may be determined.

When given a straight line on a graph, you can find the length of this line by using the Distance Between Two Points Formula. This formula uses the vertices of the beginning and ending points of a straight line to find the length of the line, which is the distance between the two points.

The Distance Between Two Points Formula is:

= √(( x₂  – x₁ )² + ( y₂ – y₁) ²)

The vertices of the line ES are E ( -3, -4 ) and S ( 4, 4 ).

The computation of sin^3(x) + cos^3(x) is mathematically given as (2/5)(1 - sin(x)cos(x))

Generally, The study of the connections between the lengths of the sides of triangles and the angles of those triangles is the subject of the mathematical discipline known as trigonometry.

Applications of geometry to astronomical research gave rise to the discipline in the Hellenistic civilization during the third century B.C.

To compute sin^3(x) + cos^3(x), we can use the identity:

sin^3(x) + cos^3(x) = (sin(x) + cos(x))(sin^2(x) - sin(x)cos(x) + cos^2(x))

We know that sin(x) + cos(x) = 2/5, so we can substitute this into the above equation: sin^3(x) + cos^3(x) = (2/5)(sin^2(x) - sin(x)cos(x) + cos^2(x))

We also know that sin^2(x) + cos^2(x) = 1, so we can substitute this into the above equation:

sin^3(x) + cos^3(x) = (2/5)(1 - sin(x)cos(x))

Then we can simplify the above equation:

sin^3(x) + cos^3(x) = (2/5)(1 - sin(x)cos(x))

The domain of the composite function f(g(x)) is equal to (x - 2)/(4 + 4x).

A function is composite when the co- domain of the first mapping is the domain of the second mapping

We shall evaluate the domain of the function f(g(x)) as follows:

f(g(x)) = 1 ÷ 12/[(x - 2) + 4]

f(g(x)) = 1 ÷ [12 + 4(x - 2)]/(x - 2) {simplify the denominator to a single fraction}

f(g(x)) = 1 ÷ (12 + 4x - 8)/(x - 2) {open bracket for 4(x - 2)}

f(g(x)) = 1 ÷ (4 + 4x)/(x - 2) {simply like terms}

f(g(x)) = 1 × (x - 2)/(4 + 4x) {changing division to multiplication}

f(g(x)) = (x - 2)/(4 + 4x)

Answer:

To calculate the interest earned on an investment, we can use the formula:

A = P(1 + r)^t

Where A is the amount in the account after time t, P is the initial principal or deposit, r is the interest rate, and t is the time in years.

In this case, the initial deposit is $8,241.78, the interest rate is 5.5% (or 0.055 as a decimal), and the time is 31 days.

Since the interest is compounded daily, we need to calculate the number of compounding periods for 31 days, which is 31 days.

Therefore, the formula becomes:

A = 8241.78(1+0.055)^31

To calculate the interest earned, we will subtract the initial deposit from the final amount in the account

Interest = A - P

So the interest earned in 31 days will be:

$8241.78 * (1+ 0.055)^31 - $8241.78 = $35094.06

The radius of the cylindrical lampshade is approximately 13.98 cm.

The formula for the curved surface area of a cylinder is 2πrL, where r is the radius, L is the height and π is pi. Given that the curved surface area of a cylindrical lampshade is 3520 cm² and the height is 40cm.

We know that:

2πrL = 3520cm²

So we can solve for the radius by dividing both sides by 2πL:

r = 3520cm² / (2π * 40cm)

Substituting the value of pi we have

r = 3520cm² / (6.284 * 40cm) = 3520cm² / 251.36cm = 13.98cm

Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable. An example of a polynomial with one variable is x^2+x-12. In this example, there are three terms: x^2, x and -12.

Based on the number of terms present in the expression, it is classified as

Monomial:-A monomial is an expression which contains only one term. For an expression to be a monomial, the single term should be a non-zero term. A Examples of monomials are: 5x,3.

Binomial:-A binomial is a polynomial expression which contains exactly two terms. A binomial can be considered as a sum or difference between two or more monomials.  Examples of binomials are:

– 5x+3, 6a^4 + 17x.

Trinomial:-A trinomial is an expression which is composed of exactly three terms. A Examples of trinomial expressions are:

– 8a^4+2x+7, 4x^2 + 9x + 7.

Now,

Given polynomials are 2x ^ 2 - 2, 3x - 9,  - 3i ^ 2 - 6i + 9.
