The 50th derivative of y=cos2x is [tex]& y^{50}(x)=-2^{50} \cos (2 x)[/tex].
Consider y=cos 2x
Derivative: The rate of change of a function with respect to a variable. Derivatives are fundamental to the solution of problems in calculus and differential equations.
Finding the nth derivative means to take a few derivatives (1st, 2nd, 3rd…) and look for a pattern. If one exists, then you have a formula for the nth derivative. To find the nth derivative, find the first few derivatives to identify the pattern. Apply the usual rules of differentiation to a function, then find each successive derivative to arrive at the nth.
The first derivative is
[tex]$$\begin{aligned}& y^{\prime}=-2 \sin 2 x \\& =-2\left[\cos \left(2 x+\frac{\pi}{2}\right)\right]\end{aligned}$$[/tex]
The second derivative is
[tex]$$y^{\prime \prime}=-2^2\left[\cos \left(2 x+2 \cdot \frac{\pi}{2}\right)\right]$$[/tex]
Similarly, we get the [tex]n^{th}[/tex] derivative
[tex]$$y^n(x)=-\left[2^n \cos \left(2 x+n \frac{\pi}{2}\right)\right]$$[/tex]
When n=50
[tex]$$\begin{aligned}& y^{50}(x)=-\left[2^{50} \cos \left(2 x+50 \cdot \frac{\pi}{2}\right)\right] \\& y^{50}(x)=-2^{50} \cos (2 x)\end{aligned}$$[/tex]
Therefore, the [tex]50^{th}[/tex] derivative of y = cos 2x is [tex]& y^{50}(x)=-2^{50} \cos (2 x)[/tex].

45/14 rounded to the nearest tenth
Answer:Not Sure if this is correct but Is it 3.2?
Step-by-step explanation:
Thats the only thing i can think of
Main answer: 3.2142857142
To Find: 45/14 rounded to the nearest tenth
Solution:
First step:
divide 45 by 14 ( Here Dividend is 45 and the divisor is 14)
Second step:
14 multiplied by 3 = 42 ( It means dividing 45 by 14 will get a 3 quotient)
Third step:
Put a decimal in the quotient to add an extra zero in the dividends to find the value in the decimal.
Fourth step:
After subtracting 42 from 45 will get 3 as a remainder
We will add 0 to find the value in decimal
so, 30 is dividend, we will again divide it by 12
14*2 = 28 ( 2 is quotient)
Fifth step:
we will get 2 as remainder
again repeat the same step by adding 0 and dividing it by 14
Sixth step:
Now, 20 divided by 14 , will get 1 as quotient and 7 as remainder
Seventh step:
6 will become 60, after dividing it by 14, will get 4 as quotient and 4 as remainder
Eighth step:
After dividing 40 divided by 14, will get 2 as quotient and 12 as remainder
as 12 is lesser than 14, we will add extra zero in dividend
after dividing 120 by 14, we will get 8 as quotient and 8 as remainder
divide 80 by 14, will get 5 as quotient and 10 as remainder
divide 100 by 14 , will get 7 as quotient and 2 as remainder
divide 20 by 14 , will get 1 as quotient and 6 as remainder
divide 60 by 14, will get 4 as quotient and 4 as remainder
divide 40 by 14, will get 2 as quotient and 12 as remainder
divide 120 by 14, will get 8 as quotient and 8 as remainder
Final answer: 3.2142857142

Circumcenter of Triangle:
The circumcenter of a triangle is defined as the point where the perpendicular bisectors of the sides of that particular triangle intersect. The parallel points of the bisectors of a triangle are called the circumcenter. This is represented by P(X,Y). The circumcenter is also the center of the triangle's circumcircle, which can be either inside or outside the triangle.
Line Segment:
In geometry, a line segment is a portion of a straight line bounded by two different endpoints and includes all points on the line between the endpoints. The length of the line segment is determined by the Euclidean distance between the endpoints. A closed line includes both endpoints, but an open line does not. A half-open line contains only one endpoint. In geometry, line segments are often denoted by lines over two endpoint symbols.
Examples of line segments are the sides of triangles or squares. More generally, if both endpoints of a segment are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if the vertices are adjacent, or a diagonal line . If both endpoints are on a curve (such as a circle), the line segment is called a chord (of that curve).

What is the example of SAS congruence?
The SAS congruence states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
First, let's take two triangles ABC and DEF. If the side lengths of both triangles are the same (AB = DE, AC = DF) and the included angle (angle A) is the same in both triangles (angle A = angle D) then the two triangles are congruent. This is known as the SAS congruence.
To prove the SAS congruence, we can use the Law of Congruent Triangles. This law states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
To prove this, we can use the Side-Angle-Side Postulate. This postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
This means that if the side lengths of both triangles are the same (AB = DE, AC = DF) and the included angle (angle A) is the same in both triangles (angle A = angle D) then the two triangles are congruent. This is known as the SAS congruence.

x + 5 ≤ 1 or x - 7 ≥ -3
Subtract both sides of the inequalities by the constant terms
So, we have the following representation
x + 5 - 5 ≤ 1 - 5 or x - 7 + 7 ≥ -3 + 7
Evaluate the differences
This gives
x ≤ -4 or x ≥ 4
The ≤ and ≥ means that the circles on 4 and -4 are closed circles
It also means that the arrows point to different directions and they never meet
Hence, the graph is (d)

use series to evaluate the limit. lim x → 0 sin(3x) − 3x + 9 2 x3 x5
The limit as x approaches 0, or lim x → 0 of sin(3x) – 3x + 9/2x3x5 is 9.
This limit, which can be written as Lim, the approach can be evaluated by rewriting or rephrasing the limit as a power series and evaluating the limit from one term to the other limit term. The power series of the sin(3x) is 3x - (9/2)x3 + (27/8)x5 - (81/16)x7 + (243/128)x9 - O(x10). As the x approaches the 0, the higher-order terms are very much negligible as well as the limit itself simplifies to the calculations as given below:
9 – 0 + 9/2 = 9.
