What is the sine for the figure below?
Answers
The sine for the right triangle A is 3/5.
The ratio between the side opposite the angle and the triangle's hypotenuse is known as the sine (sin) of an acute angle in a right-angled triangle. A right angle in geometry and trigonometry is an angle that is exactly 90 degrees, or 2 radians, which is equivalent to a quarter turn. If a ray is positioned so that its terminal is on a line and they are equal, the neighbouring angles are right angles.
Sin(A) = opposite/hypotenuse
=BC/AB
=3/AB
Given,
BC = 3
AC = 4
Now solve for AB using Pythagorean theorem:
BC2 + AC2 = AB2
32 + 42 = AB2
9 + 16 = AB2
25 = AB2
AB = 5
Hence,
The value of AB is 5.
BC/AB = 3/5
Therefore, The sin of triangle A is 3/5.

Answers
I bought 2 small notebooks and 4 large notebooks.
Let us represent the number of small notebooks with x and number of large notebooks with y.
Forming equation according to bought number of books -
x + y = 6 - equation 1
Rewriting the equation according to x
x = 6 - y - equation 2
Now, forming equation according to cost of notebooks -
8x + 10y = 56 - equation 3
Keep the value x from equation 2 in equation 3
8 (6 - y) + 10y = 56
Performing multiplication
48 - 8y + 10y = 56
Performing subtraction and shifting values to other side of equation
2y = 56 - 48
2y = 8
Shifting 2 to other side of equation and performing division
y = 8 ÷ 2

Answers
Answer:

Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180.
We can write the following equation to find, first value of m, then the value of n:
65 + 42 + 55 + m = 180 add like terms
162 + m = 180 subtract 162 from both sides
m = 18

Two people pair up to create a sequence. Each of them pick five random digits from 1 to 9 (with repetitions, if they
wish). They merge their digits to make a list of ten. Now, each of them construct a different ten-digit number using
exactly the digits in the list. Let a₁ = the (positive) difference between the two numbers. Let an+1 = the sum of the
digits of an for n21. This sequence converges because it is eventually constant. What is the limit?
Answers
Answer: The nth term of the sequence whose integers are between 1 -9 such that there is the permission of repetition but no two consecutive digits must be even is 1.834 x [tex]10^{21}[/tex]
Step-by-step explanation:
Given data,
Two people pair up to create a sequence. Each of them pick five random digits from 1 to 9.
Define Consecutive numbers :
Consecutive numbers are numbers that follow each other in order. They have a difference of 1 between every two numbers. In a set of consecutive numbers, theme an and the median are Equal. If n is a number, then n, n+1, and n+2 would be consecutive numbers Examples. 1, 2, 3, 4, 5.
The numbers that are given:
1, 2, 3, 4, 5, 6, 7, 8, 9 are all consecutive.Now, suppose a (n) denotes the number of n-digit positive integers as stated in the question, thereby using:
1, 2, 3, 4, 5, 6,7, 8, 9 with the permission of repetition; no two consecutive digits are even.Then, the number of n can be computed as n!= (9!) x (8!) x (7!) × (6!) × (5!) × (4!) × (3!) × (2!) × (1!)
= 362880 x 40320 x 5040 x 720 x 120 x 24 x 6 x 2 x 1
[tex]n^{th}[/tex] = 1.834 x [tex]10^{21}[/tex]
Therefore,
The nth term of the sequence whose integers are between 1 -9 such that there is the permission of repetition but no two consecutive digits must be even is 1.834 x [tex]10^{21}[/tex].

Answer:
The value of x after simplification is 6, which when substituted in the given expression will make both the sides equal.
Step-by-step explanation:
It is given that the expression given below is to be simplified using the order of operations;
The given expression is;
=> (3×2)² + 8 = ___² + 8
Now, let us assume that the blank space is 'x' in the above-mentioned question;
Firstly,
We will solve the terms within brackets as per BODMAS rules that is multiplication of both the terms;
=> (3×2)² + 8 = x² + 8
=> 6² + 8 = x² + 8
Now, we will solve the squares of the terms given above;
=> 36 + 8 = x² + 8
Now, we will add the terms as per BODMAS rules;
=> 44 = x² + 8
=> 44 - 8 = x²
Now, we will subtract the terms as per BODMAS rules;
=> 36 = x²
Now, we will square-root both the sides given above;
=> x = √36
=> x = 6
Therefore, the value of x after simplification is 6, which when substituted in the given expression will make both the sides equal.

What is the slope of the line?

hi
Slope is 2 .
here is how you do the trick : by reading on the graph
if you go forward of 1 on the X axis , how much did the line goes up or down ?
Here at 0 on X- axis, we are at 0 on the Y- axis.
If you go forward of 1 on X axis, you are at 2 on Y axis.
So the slope is + 2
Other technique by calculus between two points.
Take two diffents point on the X axis. Call them A and B
Slope is : ( f(A) -f(B) ) / A-B
exemple here : we have two easy points . Take 0 as A and 1 as B
We read on the graph :
A = 0 and B = 1
f(A)= 0 and f(B) = 2
Now we apply formula :
( f(A) -f(B) ) / (A-B )
(0 -2 ) / (0-1) = -2/-1 = 2
Slope is 2

Determine whether each set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer.
4.2,6.4,7.6
Answers
Yes, the given set of numbers can be the measures of the sides of a triangle. The triangle is obtuse.
By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.
4.2 + 6.4 > 7.6
6.4 + 7.6 > 4.2
7.6 + 4.2 > 2.6
Hence, these set of numbers can be the measures of the sides of a triangle.
According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:
acute if [tex]a^{2} + b^{2} < c^{2}[/tex]
obtuse if [tex]a^{2} + b^{2} > c^{2}[/tex]
right if [tex]a^{2} + b^{2} = c^{2}[/tex]
∴The longest side is 7.6.
Hence, a = 4.2, b = 6.4 and c = 7.6;
Consider [tex]a^{2} + b^{2}[/tex] :
= [tex]4.2^{2} + 6.4^{2}[/tex]
= 58.6.
Now consider [tex]c^{2}[/tex] :
= [tex]7.6^{2}[/tex]
=57.76.
Thus, [tex]a^{2} + b^{2} > c^{2}[/tex]
Hence, the triangle is obtuse.

What is coordinates ?
Coordinates are a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane. The x axis (horizontal) and y axis are the two axes that make up a coordinate plane (vertical).The formulae for finding the new coordinates are given by
x' = x cosθ - y sinθ
y' = x sinθ + y cosθ
Substituting θ = 270
x' = x cos270° - ysin270° = x(0) - y( -1) = y
y' = x sin270° + y cos270° = x(-1) + y( 0) = x
