According to the question, Triangles are said to be in SSS (Side-Side-Side) congruence if their third sides are the same length as the third sides of another triangle.

One of the following conditions must be satisfied for two triangles to be considered congruent: There is equality between all three pairs of corresponding sides. Two matching side pairs have identical angles between them, as well as equal sides between them. The corresponding sides between two sets of corresponding angles and their two pairs are equal.

If both of a triangle's three sides and three angles are equal in any orientation, the two triangles are said to be congruent.

When all three corresponding sides are the same length and all three corresponding angles are the same size, two triangles are said to be congruent. Slides, rotations, flips, and turns can be used to make these triangles appear identical.

The domain of the function [tex]f(x) =log x[/tex] is (0, ∞) which means the given function is defined for all the values greater than 0.

The domain of the function is the set of numbers for which the function is defined. It acts as input for the function and gives output known as range.The range of the function is the set of numbers of possible output values.It is derived from set of inputs known as domain.

Given function can also be written as   [tex]y=log_{10}x[/tex]

                                                             ⇒ [tex]10^{y}=x[/tex]

This means the domain of  [tex]logx[/tex]  is the set of all values that [tex]10^{y}[/tex] can be.Since 10 is a positive integer which means its power with any number will always be positive.Therefore domain of function [tex]logx[/tex] will always be positive.

The commutative and associative properties of multiplication help you find this product:

  [tex]\dfrac{5}{8}a\,\times\,\dfrac{3}{7}a = \left(\dfrac{5}{8}\cdot\dfrac{3}{7}\right)\times (a\cdot a)=\dfrac{5\cdot3}{8\cdot7}a^2=\boxed{\dfrac{15}{56}a^2}[/tex]

The range of the function g(x) = √-(x2 + 4) is |x| ≥ 2

Range of the function g of x is equal to negative square root of the quantity x squared plus 4.

The range of the function g(x) = √-(x2 + 4) can be determined by solving the inequality g(x) ≤ 0.

To solve the inequality, we need to first simplify the expression by squaring both sides:

(√-(x2 + 4))2 ≤ 0

-x2 - 4 ≤ 0

-x2 ≤ 4

x2 ≥ -4

Now, we can take the square root of both sides to get the final expression:

|x| ≥ √-4

|x| ≥ 2

Therefore, the range of the function g(x) = √-(x2 + 4) is |x| ≥ 2.

To form a triangle, all three sides must follow the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the length of the third side. In this case, 3 + 5 is not greater than 9, making it impossible to form a triangle. This theorem is based on the idea that the longer side of a triangle must always be opposite the largest angle. Therefore, the longest side of the triangle must be less than the sum of the other two sides.

[tex]f^{-1}{x} = \sqrt{(x+4)} + 1[/tex], is the inverse function of f(x) = (x-1)² - 4

What is an inverse of a function?

In mathematics, an inverse function is a function that undoes the effects of another function. Given a function f(x), the inverse function of f(x) is denoted as f^-1(x) or as f^1(x). The inverse function f^-1(x) satisfies the condition that f(f^-1(x)) = x and f^-1(f(x)) = x for all x in the domain of the function.

To find the inverse of a function, one common way is to algebraically manipulate the function and the relationship between the function and its inverse.

To identify the inverse of the function f(x)=(x-1)^2-4, we can start by swapping x and y in the original function:

y = (x-1)^2-4

Then we need to solve for x:

x = (y+4)^0.5 + 1

To check that this is indeed the inverse function, you can substitute x = (y+4)^0.5 + 1 into f(x) and check that you get back y:

f((y+4)^0.5 + 1) = (((y+4)^0.5 + 1)-1)^2-4 = y

Hence, [tex]f^{-1}{x} = \sqrt{(x+4)} + 1[/tex], is the inverse function of f(x) = (x-1)² - 4.

The flat fee that the store charges for renting a vacuum cleaner can be found by substituting 0 into the equation f(x) = 6x + 14. Doing this yields f(0) = 14, meaning the store charges a flat fee of 14.

The function f(x) = 6x + 14 models the total rental cost of a vacuum cleaner. This equation can be used to calculate the total rental cost of the vacuum cleaner. The equation is solved by substituting the number of hours the vacuum cleaner is rented for, x, into the equation. The flat fee that the store charges can be found by setting x equal to 0 in the equation, f(x) = 6x + 14. When x is set to 0, the equation becomes f(0) = 6(0) + 14. Simplifying the equation yields f(0) = 14. This means that the flat fee the store charges is 14.

To summarise, the flat fee that the store charges for renting a vacuum cleaner can be found by substituting 0 into the equation f(x) = 6x + 14. Doing this yields f(0) = 14, meaning the store charges a flat fee of 14.

The sum of the infinite series can be approximated by adding up the first few terms. The series is of the form (−1)^n/4^n n! with n = 1,2,3,4,… The first term is 1/4, which is the sum when n=1. The second term is then (-1/16), which is the sum when n=2. This pattern continues, with the next terms being 1/384 and -1/18432, respectively. After adding up the first five terms, we get a sum of 0.673975. Therefore, the sum of the series is approximately 0.6740, calculated to four decimal places.

The area of the large rectangle shown in the image is (2 + 3 + 4)a unit square

An equation is an expression that shows the relationship between two or more numbers.

Area is the amount of space occupied by a two dimensional shape or object.

The area of a rectangle is the product of its length and width. It is given by the equation:

Area of a rectangle = length * width

From the diagram:

Width = a; length = 2 + 3 + 4

Area = length * width

Substituting the terms into the equation:

Area = (2 + 3 + 4)a

Further simplification gives:

Area = 2a + 3a + 4a

The area of the rectangle is 2a + 3a + 4a
