The radius of convergence is 1.
The interval of convergence is [8, 10).
How to find the radius of convergence?We can use the ratio test to find the radius of convergence, r:
lim (n → ∞) |(x - 9)^(n+1)/(x - 9)^n|= lim (n → ∞) |x - 9|= |x - 9|The series converges if the limit is less than 1, which gives us:
|x - 9| < 1
So, the radius of convergence is 1.
How to find the interval of convergence?To find the interval of convergence, we need to test the endpoints of the interval [8, 10].
For x = 8, the series becomes:
∑ (8 - 9)^n = ∑ (-1)^n
which is an alternating series that converges by the alternating series test.
For x = 10, the series becomes:
∑ (10 - 9)^n = ∑ 1^n
which is a divergent series.
Therefore, the interval of convergence is [8, 10), which includes the endpoint x = 8 and excludes the endpoint x = 10. In interval notation, this can be written as [8, 10).

The size of a computer monitor is usually given by the length of its diagonal. A monitor's aspect ratio is the ratio of its width to its height. This monitor has a diagonal length of 27 inches and an aspect ratio of 16:9. Using ratios and the Pythagorean Theorem the approximate width is 23.5 inches and the height is inches.
The length and width of the computer monitor is 23.36 inches
and 13.14 inches.
According to the given statement
we have given that
The length of diagonal of rectangular monitor = 27 inches
The length to width ratio is 16:9
So , Let the Length of monitor = 16x
and The Width of monitor = 9x
And we have to find the length and width of the computer monitor.
So, For this purpose,
From Pythagoras theorem
(Diagonal)² = Length² + width²
Put the values in it and then
27² = (16x)² + (9x)²
729 = 256x² + 81x²
After solving we get
337x² = 729
So, x² = 2.16
∴ x = = 1.46 inches
So, The length = 16x = 23.36 inches
And The width = 9x = 13.14 inches.
Hence, The length and width of the computer monitor is 23.36 inches
and 13.14 inches.

Solve the system of equations 2x-2y=-14 and 3x-y=-1 by combining the equations.
Combining the equations, the solution to the system of equations is: x = 3, y = 10.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the equations are:
2x - 2y = -14.3x - y = -1.Combining(adding) them, we have that:
5x - 3y = -15.
From the second equation:
y = 3x + 1.
Replacing in the combined equation:
5x - 3(3x + 1) = -15.
-4x = -12
x = 3.
y = 3x + 1 = 3 x 3 + 1 = 10.

Due to length restriction we kindly invite to check the explanation for further details about the analysis of three quadratic equations and inherent rigid transformations.
How to difference between parent quadratic equations and resulting quadratic equations
Herein we find the graph of the parent quadratic equation f(x) = x² and two proposed resulting functions, whose difference with the former one have to be explained in terms of the kind of rigid transformations they have.
By comparing them, we find that both functions g(x) and h(x) are the result of a rigid transformation of the form f'(x) = k · f(x), where the transformation is a simple vertical dilation for k > 1, simple vertical contraction for 0 < k < 1, vertical contraction and reflection around the x-axis for - 1 < k < 0 and vertical dilation and reflection around the x-axis for k < - 1.
Function g(x) is the result of dilating f(x) by a factor of 3 and function h(x) is the result of dilating and reflecting f(x) around the x-axis by a factor of - 3.
The tables for each quadratic function are summarized below:
g(x):

g(x) 12 3 0 3 12
f(x):

Using translation concepts, the inequality that represents the graph is given as follows:
f(x) > sqrt(1 - x)
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
The parent square root function is given by:
y = sqrt(x)
It increases to right starting at x = 0, and in this problem it increases to left starting at x = 1, meaning that it was reflected over the y-axis and shifted right one unit, hence the function is:
sqrt(1 - x)
The part graphed is the values above the function, that is, the values that are greater, as the line is only dashed, hence the inequality is:

How to analyze quadratic equations
In this question we have a graph of a quadratic equation translated to another place of a Cartesian plane, whose form coincides with the vertex form of the equation of the parabola, whose form is:
g(x) = C · (x - h)² - k (1)
Where:
(h, k) - Vertex coordinatesC - Vertex constantBy direct comparison we notice that (h, k) = (5, 1) and C = 1. Now we proceed to check if the points (x, y) = (2, 10) and (x, y) = (8, 10) belong to the parabola.
x = 2
g(2) = (2 - 5)² + 1
g(2) = 10

The five consecutive integers are -2, -1, 0, 1 and 2.
What are the values of the integers?
Given that;
The sum of five consecutive integers equals 5.5 times the middle integer.
Since the integers are consecutive, let the integer be;
x, x+1, x+2, x+3 and x+4.
Now, sum of the integers equals 5.5 times the middle integer.
Middle integer is x+2.
Hence we have;
x + x+1 + x+2 + x+3 + x+4 = 5.5( x+2 )
x + x+1 + x+2 + x+3 + x+4 = 5.5x + 11
We collect like terms
x + x + x + x + x - 5.5x = 11 - 1 - 2 - 3 - 4
5x - 5.5x = 1
-0.5x = 1
x = -( 1 / 0.5 )
x = -2
Since our integers are; x, x+1, x+2, x+3 and x+4.
We substitute in the value of x
x = -2
x+1 = -2 + 1 = -1
x+2 = -2 + 2 = 0
x+3 = -2 + 3 = 1
