A limit is generally written as
[tex]lim _{x- > c} f(x) = L[/tex]
It is read as “the limit of f of x, as x approaches c equals L”
A limit in mathematics is a point at which a function approaches the output for the specified input values. Calculus and mathematical analysis depend on limits, which are also used to determine integrals, derivatives, and continuity. It is employed in the analysis process and constantly considers how the function will behave at a specific point. The idea of the limit of a topological net broadens the definition of the limit of a sequence and relates it to the limit and direct limit in theory category. In general, there are two sorts of integrals: definite integrals and indefinite integrals. The upper limit and lower limit for definite integrals are correctly defined.
Let us consider a real-valued function “f” and the real number “c”, the limit is normally defined as:
[tex]lim _{x- > c} f(x) = L[/tex]
It is read as “the limit of f of x, as x approaches c equals L”. The “lim” shows limit, and fact that function f(x) approaches the limit L as x approaches c is described by the right arrow.
Let us take an example to fully understand how to write limits.
[tex]lim_{x- > 2} 2x + 2[/tex]
= 2(2) + 2 = 6
This is how to write and represent limits.

What is a fraction?Is a number that expresses the portion of some number over a total. The number that expresses the portion is known as the numerator and the number that expresses the total is known as the denominator.
To solve this problem we must perform the corresponding algebraic operations with mixed fraction.
Original equation:
4 / (1 1/3)
A mixed operation is solved as follows:
For the denominator: the same denominator is placed.
For the numerator:
The value of the denominator is multiplied by the integer component.The result is added to the numerator of the fraction.We transform the mixed fraction into improper fraction and we have:
1 1/3 = [(3*1) + 1)] /3 = [3+ 1] /3 = 4/3
Now, describing the equation with the improper fraction we get:
4 / (4/3)
Solving the division with fractions we have:
(4*3) / 4

What is the y-intercept of y =- 3 4x 6?.
1) y intercept in the given equation is 6
The graph's intersection with the y-axis is known as the y-intercept. Finding the intercepts for any function with the formula y = f(x) is crucial when graphing the function. An intercept can be one of two different forms for a function-t he x-intercept and the y-intercept. A function's intercept is the location on the axis where the function's graph crosses it.
An equation of a straight line is written in the form: y=mx+c
where y is the y-coordinate,
m is the slope of the line,
x is the x-coordinate
and c is the y-intercept
Thus, from the question, y=3/4x+6, we can say

What is the trigonometric ratio of Cosθ?.
When we have a right triangle, Cos = a / h, according to the cosine law. In this situation, the letter "a" stands for adjacent.
The hypotenuse, denoted by the letter "h," can be calculated using the Pythagorean Theorem. All you need to get cosine is the hypotenuse and the neighboring side.
The ratio of the length of the side next to the angle divided by the length of the triangle's hypotenuse is known as the cosine of an angle.
The triangle's sides, a, b, and c, are determined using the cosine formula, which is given as
c = [a2 + b2 - 2ab cos C]
According to the Cosine Rule in trigonometry, the square of the length of any side of a given triangle equals the sum of the squares of the other sides minus twice the product of the other two sides multiplied by the cosine of the angle that separates them.

A car travels 2 miles in 5 minutes at a constant speed. How far did the car travel in 30 minutes?
Running a mile in five minutes is similar to moving at 12 mph (19.4 kph) on a treadmill.
How is miles calculated?
the statutory mile, which has a length of 5,280 feet, is one example of a mile (1.609 km). Its original unit of measurement was the 5,000-foot-long Roman mile passus, often known as the "thousand paces."
Discover the distance formula, a Pythagorean theorem application, to determine the separation between two places. To get the separation between any two points, we can rewrite the Pythagorean theorem as d=((x 2-x 1)2+(y 2-y 1)2).
The formula for the distance between the points (a,b) and (c,d) is square root of (a,c)2 + (b,d)2. The distance in three dimensions between points (a, b, c) and (d, e, f) is equal to the square root of (a, d), (b, e), and (c, f)2.
We have,
Car speed = 0.4 miles per minute
We need to find the distance traveled in 30 minutes with a speed of 0.4 miles per minutes.
Speed is given by:
Speed = Distance / Time
Distance = Speed x Time
Distance = 0.4 x 30

The average rate of change in the number of inches of snowfall from January 8 to January 11 include the following: A. 2/3 in.
What is the rate of change?In Mathematics, the rate of change is sometimes referred to as slope or gradient and it can be calculated by using this formula;
Rate of change, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Rate of change, m = (y₂ - y₁)/(x₂ - x₁)

4. Find the equation of the line passing through the point (3.2) and parallel to line x + 2y = 5
5. Find the equation of the line passing through the point (2,5) and parallel to line x + 3y - 8
Answer:
To find the equation of the line passing through the point (3,2) and parallel to line x + 2y = 5, we need to use the point-slope form of a linear equation. The point-slope form of a linear equation is: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
We know that two lines are parallel if they have the same slope. Since the given line x + 2y = 5 has a slope of -1/2, the equation of the line passing through (3,2) and parallel to x + 2y = 5 is y - 2 = -1/2 (x - 3), or simplifying y = -1/2x + 7/2
To find the equation of the line passing through the point (2,5) and parallel to the line x + 3y - 8, we need to use the point-slope form of a linear equation. The point-slope form of a linear equation is: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
We know that two lines are parallel if they have the same slope. Since the given line x + 3y - 8 has a slope of 1/3, the equation of the line passing through (2,5) and parallel to x + 3y - 8 is y - 5 = 1/3 (x - 2), or simplifying y = 1/3x + 1/3
It's important to note that the lines are parallel because they have the same slope and different y-intercept, which means that they will never intersect.
Step-by-step explanation:
Write a possible equation for a sine function that has a minimum point at (-3, 0) and a maximum point at (-9, 6).
The sinusiodal function created from 2 given points is y = 3 sin (πx + 90) + 3
From the case, we have:
Minimum point = (-3,0)
Maximum point = (-9,6)
The sinusoidal fuction would be in the form of:
y = A sin (Bx - C) + D
where:
A = amplitudo
B = 2π / Period
C = Phase shift
D = Midline
First, we need to find the amplitudo:
A = (Y max - Y min) / 2
A = (6 - 0) / 2
A = 3
Periode = (X max - X min) x 2
Periode = (-9 - (-3) x 2
Periode = -6
B = 2π / Periode
B = 2π / 6
B = 1/3 π
D = (Y max + Y min) / 2
D = (6 + 0) / 2
D = 3
We can use one point to find the value of C:
0 = 3 sin (π/3 (-3) - C) + 3
0 = 3 sin (π - C) + 3
-3 = 3 sin (π - C)
sin (π - C) = -1
(π - C) = 270
C = -1/2 π
C = - 90
Then the sinusiodal function would be:

Show your work.
The difference in volume between the cereal box and pastry box is 167.991 cubic inches.
What are Dimensions?
Dimensions refer to the measurement of the size or extent of an object or space in a particular direction, such as length, width, and height. In the context of boxes, dimensions are used to describe the length, width, and height of a box, usually given in inches or centimeters.
To find the volume of a rectangular box, we use the formula:
Volume = length x width x height
Let's first find the volume of the cereal box:
Volume of cereal box = 7 inches x 12 inches x 2 inches = 168 cubic inches
Now let's find the volume of the pastry box:
Volume of pastry box = 3% inches x 3% inches x 2% inches = 0.009 cubic inches
Now, to find the difference in volume between the two boxes, we subtract the volume of the pastry box from the volume of the cereal box:
168 cubic inches - 0.009 cubic inches = 167.991 cubic inches
Hence, the difference in volume between the cereal box and pastry box is 167.991 cubic inches.
