The properties of limit are the following:

A limit is a value which obtained when a function approaches the output value for an input value. For a variable x approaches a particular value say "a", i.e., x → a and limit is denoted as [tex] \lim_{x \to a} f(x) \\ [/tex].

The basic properties of limit are :

1) Sum rule : limit of sum of two functions is equal to sum of individual function limit.

[tex]\lim_{x \to a} (f(x) + g(x)) = \lim_{x \to a} f(x) + \lim_{x \to a}g(x) \\ [/tex]

2) Product rule : The limit of product of two functions is equal to product of individual function limits.

[tex]\lim_{x \to a} (f(x) \times g(x)) = \lim_{x \to a} f(x) \times lim_{x \to a} g(x) \\ [/tex]

3) Difference rule : The limit of difference of two functions is equal to difference of individual function limits.

[tex]\lim_{x \to a} (f(x)-g(x))=\lim_{x \to a} f(x) - \lim_{x \to a}g(x) \\ [/tex]

4) Law of constant : The limit of a constant is equal to constant itself.

[tex]\lim_{x \to a}c \: = c \\ [/tex]

5) Constant multiply rule : The limit of product of constant with function is equal to constant times limit of function.

[tex]\lim_{x \to a} (k \times f(x)) = k\times lim_{x \to a}f(x)\\ [/tex]

Two matrices are row equivalent if they can be transformed into each other using elementary row operations.

Elementary row operations are operations such as the addition or subtraction of two rows, the multiplication or division of a row by a non-zero constant, or the interchange of two rows. Row equivalent matrices are equal in terms of row space, meaning any linear combination of the rows of one matrix will yield the same linear combination of the rows of the other matrix. An example of two row equivalent matrices is given below:

Matrix A =

[tex]\begin{bmatrix} 1 & 2 & 3 \\4 & 5 & 6 \end{bmatrix}[/tex]

Matrix B =

[tex]\begin{bmatrix} 1 & 2 & 3 \\2 & 3 & 4 \end{bmatrix}[/tex]

These matrices are row equivalent because adding the first row of Matrix A to the second row of Matrix B yields Matrix A. To show this mathematically, let row 1 of Matrix A be represented as r1, and row 2 of Matrix B be represented as r2. We can then say that r2 + r1 =

[tex]\begin{bmatrix} 1 & 2 & 3 \\6 & 8 & 10 \end{bmatrix}[/tex]

Answer:

L = 53.37 cm

Step-by-step explanation:

We have the relationship

M ∝ L³

We can rewrite this as an equation:
M = k · L³

where k, a constant, is known as the constant of proportionality

Given M = 100 kg when L = 20, we get

100 = k · 20³

100 = k · 8000

k = 100/8000 = 0.0125

If M = 1900 kg and k = 0.0125 we can plug in these values to get

1900 = 0.0125 L³

==>  L³ = 1900/0.0125

==> L³ = 152000

Therefore L = ∛152000

L = 53.36803 or

L = 53.37 cm  rounded to 2 DP

The solution of the system of equations y = 2x - 3.5 and x - 2y = -14 is (7, 10.5).

In the given question, we have to solve the solution to the system of equations

y = 2x - 3.5..................(1)

x - 2y = -14...............(2)

Now putting the value of y from the equation 1 in the equation 2.

x - 2(2x - 3.5) = -14

Now simplifying the expression using the distributive property

x - 4x + 7 = -14

-3x + 7 = -14

Subtract 7 on both side, we get

-3x = -21

Divide by -3 on both side, we get

x = 7

Now putting the value of x in the equation 1,

y = 2(7) - 3.5

y = 14 - 3.5

y = 10.5

A right angle is defined as an angle that measures exactly 90 degrees.

To prove this:

This definition of a right angle has been established by mathematical convention, and it is widely accepted and used in mathematics and geometry. The reason for this is that a right angle is the most convenient and natural angle to use as a standard unit of measure for angles.

One reason is that a right angle is easy to construct and measure. A right angle can be created by using a square or a set square, which are simple and inexpensive tools. Also, right angles are found in many natural and man-made objects, such as corners of walls and buildings, which makes them easy to recognize.

Another reason is that a right angle is a fundamental building block in Euclidean geometry, and it is used to define other geometric concepts such as parallel lines and perpendicular lines. The properties of a right angle make it a useful tool for solving geometric problems and for understanding the relationships between angles and shapes.

In summary, the 90 degrees definition of a right angle is a mathematical convention that is widely accepted due to its convenience, natural appearance in many objects, and its importance in Euclidean geometry.

Answer:

f = 53.13 degrees

Step-by-step explanation:

An isosceles triangle has two equal sides, so in this case the sides of length 60cm are equal. The base angle (f) is opposite the base of the triangle, which is the side of length 100cm.

To find the base angle, we can use the law of cosines.

c^2 = a^2 + b^2 - 2ab*cos(f)

where c is the hypotenuse (the side of length 100cm), a and b are the legs (the sides of length 60cm), and f is the base angle we are trying to find.

Substituting in the given values, we get:

100^2 = 60^2 + 60^2 - 2(60)(60)cos(f)

Simplifying this equation, we get:

10000 = 3600 - 3600cos(f)

so

cos(f) = (10000-3600)/3600 = 6400/3600 = (8/3)^2

then

f = cos^-1((8/3)^2)

Therefore, f = 53.13 degrees

Let u and v be a vectors. Then u can be broken up into two components, r and s such that r is parallel to v and s is perpendicular to v.

The component of u perpendicular to v is referred to as s, while r is referred to as the projection of u onto v. Then, u v = u1v1 + u2v2 + + unvn is the dot product of u with v.

Keep in mind that u v is defined when u and v have the same number of components and that the dot product of two vectors is a scalar. Though the dot product is a union of two vectors, the outcome is not a vector, which is an intriguing observation.

What is function ?

function can be defined in such a way that it relates an input to the output.

Given function y = x-3

The degree of the function means the highest power of the variable

Here, the degree is 1, it is odd.

The leading coefficient is 1, which is positive.

By taking sample values of x, we get values of y with the graph as shown

From the graph, we can say that the degree of the function is odd, so the ends of the graph continue in opposite directions

Because the leading coefficient is positive, the left side of the graph continues down the coordinate plane and the right side continues upward.

The following describes the function x-3  that the degree of the function is odd, so the ends of the graph continue in opposite directions.

Let the first point be A ( 0 , 1000 )

Let the second point be B ( 1 , 800 )

Now , the exponential equation be represented as A

y = abˣ   be equation (1)

The APR if the finance terms are $21.99 per week for 52 weeks is 83.48%. Hence option 4 is correct.

The annual percentage rate, or APR, is the interest rate that is charged on a loan balance that is still outstanding. The expected cost of the annual fees connected with a certain sort of borrowing is what the APR conceptually reflects.

APR is a commonly used formula by lenders that enables borrowers to compare various loan choices. The stated interest rate on a loan is typically insufficient on its own to help borrowers choose the best loan option.

A loan with a low stated interest rate could also have significant costs attached that should not be disregarded. The best alternative might be a loan with a smaller fee structure and a higher advertised interest rate. APR is calculated as (Periodic Interest Rate x 365 Days) x 100 i.e.

[tex]$\mathrm{APR=\left(\left(\frac{\frac{Fees+Interest}{Principal}}{n} \right) \times 365 \right) \times 100}[/tex]

​where:

Interest = Total interest paid over life of the loan

Principal = Loan amount

n = Number of days in loan term

Fees = 0

​Interest = 2​Interest = $519.48

Principal = $624.00

n = 52 × 7 = 364 days

Plug the data in the formula:-

[tex]$\mathrm{APR=\left(\left(\frac{\frac{0+519.48}{624}}{364} \right) \times 365 \right) \times 100}[/tex]
