can any one explain why you have to do Addition and Subtraction in Scientific Notation or how we will use it in the real world
We must remember to multiply each integer by a power of 10 while subtracting numbers in scientific notation.
what is significant figures ?A value's accuracy is influenced by the number of significant digits in the value, which is frequently a measurement. Count the significant digits starting with the first non-zero digit. All zeros are permitted in the decimal places to the right of the last non-zero place. Consider the five significant digits in the number 0.0079800. Any zeros to the right of the last non-zero digit, when they come from the measurement, are significant. rounding an integer to 3 significant digits and 3 decimal places is identical. Go up to three and begin counting at the first digit that is not zero. Remove the last digit after that. The final two digits to the right of the decimal point should be increased by zeros.
To make it simple to subtract these integers, they must all be in the same power, as demonstrated in the example below.
5×10^2−3×10^2=
5(100)−3(100)^2×10^2=
(500−300)^2×10^2
=200
However, before continuing, we must restate the numbers in similar powers of ten if the powers of ten for the numbers to be subtracted are not the same.

What is variables?In programming, a variable is a value that can change, depending on conditions or on information passed to the program. Typically, a program consists of instruction s that tell the computer what to do and data that the program uses when it is running. The data consists of constants or fixed values that never change and variable values (which are usually initialized to "0" or some default value because the actual values will be supplied by a program's user).Usually, both constants and variables are defined as certain data type s. Each data type prescribes and limits the form of the data. Examples of data types include: an integer expressed as a decimal number, or a string of text characters, usually limited in length.In object-oriented programming , each object contains the data variables of the class it is an instance of. The object's method s are designed to handle the actual values that are supplied to the object when the object is being used.To learn more about decimal number refer to:

What is the length of the hypotenuse of a 45 45 90 triangle?
The length of the hypotenuse of a 45 45 90 triangle with one side of length 8 is 8√2.
The length of the hypotenuse of a 45 45 90 triangle can be calculated using the Pythagorean Theorem. The Pythagorean Theorem states that the sum of the squares of the two sides of a right triangle is equal to the square of the hypotenuse. This can be expressed mathematically as a2 + b2 = c2, where a and b represent the lengths of the two sides and c represents the length of the hypotenuse.
In a 45 45 90 triangle, both sides are equal in length. This means that the mathematical equation simplifies to a2 + a2 = c2 or 2a2 = c2. To calculate the length of the hypotenuse, we can solve for c by taking the square root of both sides, resulting in c = √2a.
In this particular example, if the length of one of the sides is 8, then the length of the hypotenuse can be calculated as c = √2(8) = 8√2. Therefore, the length of the hypotenuse of a 45 45 90 triangle with one side of length 8 is 8√2.

If the sum of 1/ of a number and 15 is 13.Find the number?
Answer:
-2
Step-by-step explanation:
Let's call the unknown number x.
We are given that:
1/x + 15 = 13
To find the value of x, we need to isolate x on one side of the equation.
To do this, we can subtract 15 from both sides:
1/x + 15 - 15 = 13 - 15
This gives us:
1/x = -2
To find x, we can multiply both sides by x:
x * (1/x) = x * (-2)
This gives us:
x = -2x
Therefore the number is -2

None of the above. The answer is 10! (10 factorial) which number is 3,628,800.
The number of ways to arrange 10 people in a line is 10! (10 factorial). This is equal to 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 which is 3,628,800.
The answer to the question is 10! (10 factorial). This is because in order to determine the number of ways to arrange 10 people in a line, you must multiply the number of people by every number between that number and 1. In this case, it would be 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 which is 3,628,800.

What is sequence?A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important.
Similar to a set, it has members (also called elements, or terms).
The length of the series is the number of elements (potentially infinite). In contrast to a set, the same items might appear more than once in a sequence at various points, and unlike a set, the order is important.
A sequence can be described formally as a function from natural numbers (the positions of the sequence's elements) to the items at each of those positions.
An indexed family, which is a function from any index set, can be thought of as a generalization of the idea of a sequence.

y varies inversely with x. Write an equation relating x and y.
Then find the indicated value. Show your work.
y = 3 when x = 8. Find the value of y when
x = 6.
y = 9 when x = 6. Find the value of x when
y = 4.
y= 1.5 when x = 14. Find the value of y when
x = 9.
y = 20 when x = 10. Find the value of x when
y = 25.
The equation of variation is xy = k.
The required values are given below.
What is proportional relationship?A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.
Given:
y inversely varies as x.
That means, y ∝ 1/x.
So, y = kx, where k constant of variation.
Then, x × y = k
When y = 8, x = 3.
k = 3 × 8 = 24
So, the equation of variation is xy = 24.
When x = 6,
6y = 24
⇒ y = 4
When y = 9, x = 6.
k = 6 × 9 = 54
So, the equation of variation is xy = 54.
When y = 4,
4x = 54
⇒ x = 27/2
When y = 1.5, x = 14.
k = 1.5 × 14 = 21
So, the equation of variation is xy = 21.
When x = 9,
9y = 21
⇒ y = 7/3
When y = 20, x = 10.
k = 20 × 10 = 200
So, the equation of variation is xy = 200.
When y = 25,
25x = 200
⇒ x = 8
Therefore, the values are given above.

What is f1 and f2 in lens?
F1 and F2 refer to the two principal focal lengths of a lens.
The two main focal lengths of a lens are referred to as f1 and f2 in the field of optics. The first principal focal length, or f1, is the distance from the lens to the point where parallel light rays, which have already passed through the lens, condense into a single point known as the focal point.
The second principal focal length, or f2, is the distance from the lens to the point where light rays diverging from a single point will appear to converge after passing through the lens. The distance from the lens to the point at which the light rays converge or diverge is known as the focal length. The values of f1 and f2, respectively, depend on the shape and type of the lens.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.
Two triangles are comparable if they have two pairs of sides that are in the same ratio and if the included angles are likewise equal.
The square of any ratio between any two matching sides of two comparable triangles is equal to the ratio of their areas. As an illustration, Area of ABC/Area of DEF equals (AB)2/(DE)2 = (BC)2/(EF)2 = (AC)2(DF)2 for any two comparable triangles ABC and DEF.

From linear equation of a line,
y=mx+c or y=mx+b
Slope of a line is m and y-intercept is c (or b).
So first we have to make y the subject in

→y= - 8x+9
y = mx + c
Hence slope is (-8) and y-intercept is 9.
for x-intercept, put y=0 and we get

x=-8/-9
x= 8/9
therefore x intercept is 8/9.
