Answer:
Similarly we can convert a limit of the form [infinity]/[infinity] to a limit of the form 0/0 or [infinity]/[infinity] by using the same technique of multiplying numerator and denominator by appropriate factors.
Step-by-step explanation:
To convert a limit of the form 0/[infinity] to a limit of the form 0/0 or [infinity]/[infinity], we can use the following algebraic manipulation:
Multiply the numerator and denominator by the reciprocal of the highest power of the variable in the denominator.
This will usually be the variable that appears in the denominator under a square root, a logarithm, or a trigonometric function.
Simplify the resulting expression by canceling out any common factors.
Evaluate the limit of the simplified expression.
Let's illustrate this with an example:
Example: Find the limit as x approaches infinity of x^2 / (e^x - 1)
Step 1: Multiply numerator and denominator by 1/x^2:
(x^2 / x^2) / [(e^x - 1) / x^2]
Step 2: Simplify the expression by canceling out x^2 in the denominator:
1 / [(e^x - 1) / x^2]
Step 3: Evaluate the limit of the simplified expression. As x approaches infinity, e^x grows faster than x^2, so the denominator goes to infinity and the limit is 0.
Therefore, we have converted the limit of the form 0/[infinity] to a limit of the form 0/0.
Similarly we can convert a limit of the form [infinity]/[infinity] to a limit of the form 0/0 or [infinity]/[infinity] by using the same technique of multiplying numerator and denominator by appropriate factors.

A tent is shown in the figure. If the amount of air only in cylindrical part is 300m^3, calculate the volume of the air in the tent.
Answer:
400 m³
Step-by-step explanation:
The tent consists of a cylinder at the bottom and the roof of the tent is a cone
The height of the cone = 2h - h = h which is the same as the height of the cylindrical part
Volume of a cylinder = πr²h where r = radius, h- height
We are given this volume = 300 m³
The volume of a cone is (1/3)πr²h
If the heights and radius are the same, the volume of the cone is 1/3 the volume of the cylinder
Volume of conical part of tent = 1/3 x volume of cylindrical part
= 1/3 x 300 = 100 m³
Total volume of the tent and therefore the volume of air
= 300 + 100 = 400 m³

How to find the solution of a system of linear equations graphically
In this problem we find two cases of systems of two linear equations with two variables, which are described by a system of the form:
a · x + b · y = c
d · x + e · y = f
Where:
a, b, d, e - Dependent variable.c, f - Independent variable.The solution of this kind of systems can be found graphically on Cartesian plane, whose procedure is described briefly:
Determine x-intercept on each line.Determine y-intercept on each line.Mark the intercepts on Cartesian plane.Construct the resulting lines. Mark the point of intersection of the two lines.Now we proceed to find the solution for each case:
Case 1
Line 1: y = 0.5 · x + 1
y-Intercept
y = 0.5 · 0 + 1
y = 1
(x, y) = (0, 1)
x-Intercept
0 = 0.5 · x + 1
0.5 · x = - 1
x = - 2
(x, y) = (- 2, 0)
Line 2: - 2 · x + 4 · y = 4
y-Intercept
- 2 · 0 + 4 · y = 4
4 · y = 4
y = 1
(x, y) = (0, 1)
x-Intercept
- 2 · x + 4 · 0 = 4
- 2 · x = 4
x = - 2
(x, y) = (- 2, 0)
Since the two lines have the same intercepts, then there are infinite solutions.
Case 2
Line 1: y = - x - 3
y-Intercept
y = - 0 - 3
y = - 3
(x, y) = (0, - 3)
x-Intercept
0 = - x - 3
x = - 3
(x, y) = (- 3, 0)

What is trigonometry?Trigonometry is the branch of mathematics that deals with the relationships between the angles and sides of triangles, particularly right triangles. Trigonometry is used to study properties such as lengths, angles, and areas of triangles and the relationships between them. It is also used in many fields, including physics, engineering, and navigation. Trigonometry is based on the study of the ratios of the sides of a right triangle. The three main ratios are sine, cosine, and tangent. These ratios are defined using the right triangle's angles and are often abbreviated as sin, cos, and tan. In addition to these three main ratios, there are also several other trigonometric functions, including cosecant, secant, and cotangent. These functions are the reciprocals of the sine, cosine, and tangent functions, respectively.
What is a right triangle?A right triangle is a type of triangle that has one angle that measures exactly 90 degrees. This angle is called the right angle and the two sides that form the angle are called the legs of the triangle. The side opposite the right angle is called the hypotenuse. A right triangle can also be defined as a triangle that has a 90-degree angle and two acute angles. The legs of the triangle are the sides that are opposite the acute angles, and the hypotenuse is the side that is opposite the right angle.

in 1 year? How much money will be in the account after 4 years?
Therefore , the solution to the given problem of interest comes out to be $324.
What is meant by interest?By dividing the original capital by the cost of borrowing, the time period, and other factors, simple interest is calculated. Simple return is calculated as follows: principal + interest + hours. This method of calculating interest is the simplest. The most typical method is to calculate it as a percent of the principal amount. For instance, if he took $100 from a buddy and promised to repay it with 5% interest, he would only be required to pay his proportion of the interest. $100 (0.05) = $5. When you make loans, you should pay interest, and you also need to when you lend money. Interest is often computed as a percentage of a loan.
Here,
Given: $300 is the principal amount
Time: 4 years,
2% interest rate
To discover the basic interest:
Using this formula
Simple interest equals
=> P*R*T/100,
=> 300*2*4/100
=> 24.

How to prove 3 points are collinear in 3d using section formula?
The section formula provides a way to check if three points in 3D space are collinear by verifying that the equation (x2 - x1)(y3 - y1) - (x3 - x1)(y2 - y1) = 0 is satisfied when their coordinates are substituted.
To prove three points are collinear in 3D using the section formula, first determine the coordinates of the three points. Then, substitute the coordinates into the section formula equation, (x2 - x1)(y3 - y1) - (x3 - x1)(y2 - y1) = 0. Finally, calculate the equation and if it is equal to 0, the three points are collinear.
For example, if the coordinates of three points are (x1, y1, z1), (x2, y2, z2) and (x3, y3, z3), then the three points are collinear if the following equation is satisfied:
(x2 - x1)(y3 - y1) - (x3 - x1)(y2 - y1) = 0
If the equation is not equal to 0, the points are not collinear. To illustrate, if the coordinates of three points are
(x1, y1, z1), (x2, y2, z2) and (x3, y3, z3),
then the three points are collinear if the following equation is satisfied: (x2 - x1)(y3 - y1) - (x3 - x1)(y2 - y1) = 0.
If this equation is not equal to 0, then the three points are not collinear. To check if the points are collinear, one must calculate the equation and determine if the equation is equal to 0. If so, the three points are collinear.

How do you determine if a triangle is right acute or obtuse?Compare the total of the squares on the two smaller sides to the square on the largest side to determine if the triangle is acute, right, or obtuse. Because of the larger sum, the triangle is sharp.
The Pythagorean formula applies to all triangles and is generalised by the law of cosines. The square of one side of the triangle, c², is said to be equal to a² + b², the sum of the squares of the other two sides, minus 2ab cos C, which is the product of the two squares times the cosine of the opposite angle.
Three closed sides make up a triangle. The Pythagoras theorem and the Heron's formula are two significant formulas that pertain to triangles.

What is y in this equation?
Answer:
y = 15.4
Step-by-step explanation:
the outer and inner triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{y}{11}[/tex] = [tex]\frac{8+3.2}{8}[/tex] = [tex]\frac{11.2}{8}[/tex] ( cross- multiply )
8y = 11 × 11.2 = 123.2 ( divide both sides by 8 )
y = 15.4
If the quadrilateral ABCD is reflected across the x-axis, what will be the coordinates of B’?
The coordinate of the point reflection across the x-axis will be (3, -6). Then the correct option is A.
What is a transformation of a point?A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
The reflection does not change the shape and size of the geometry. But flipped the image.
