What exactly is a closed area?
All space between a floor and ceiling that is enclosed on all sides by solid walls or windows, except doors that stretch from the floor to the ceiling, is referred to as an enclosed area.
What do you mean by the region that a closed curve encloses?
The sum of all infinitely thin rectangles with height f(x), enclosed by the curve y=f(x), and the x-axis between x=a and x=b, is what we mean when we write baf(x)dx.
Whether contained or not?
Use enclosed at all times. No longer regarded as a regular variety, enclosed would even be mistaken for another word by many readers. Use enclose, encloses, and enclosing rather than inclose for other words that are similar to enclosed.The graph is attached in equation y = x² , y = 2 x

nancy wants to vacation in austin texas. Hotel A charges $179 per night with a 14% nightly room tax and free parking. Hotel B charges $169 per night with 18% nightly room tax plus a one time $40 parking fee. After how many nights will Hotel B be less expesnsive?
The number of nights will be 8.62 when the Hotel B charge is less than A.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that hotel, A charges $179 per night with a 14% nightly room tax and free parking. Hotel B charges $169 per night with 18% nightly room tax plus a one-time $40 parking fee. The number of the nights will be calculated as below:-
From the given data from the equations:-
A = 179 + ( 0.14 x 179 ) x
A = 204.06x
B = ( 169 + ( 0.18 x 169 )x + 40
B = 199.42x + 40
Equate the two equations:-
204.06x = 199.42x + 40
4.64x = 40
x = 40 / 4.64
x = 8.62 nights
Therefore, the number of nights will be 8.62 when the Hotel B charge is less than A.

For each equation, find the center and radius of the circle.
(x-1)²+(y-1)²=1
The equation of the circle (x - 1)^2 + (y - 1)^2 = 1 has a radius of 1 and a center located at (1 , 1).
The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2

Find the equation for the line parallel to 3x+5y-4=0, with the same x-intercept as 2x-3y-6=0
Equation of line is 5y = -3x + 9 .
What is equation of line?
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept.
3x+5y-4=0
5y = -3x + 4
y = -3/5 x + 4/5
since it is parallel, its slope, m is -3/5
2x-3y-6=0
3y = 2x - 6
y = 2/3x - 2
at x-intercept, y is zero
2 = 2/3x
x = 3
therefore
y = mx + c
0 = (-3/5 * 3 ) + c
c = 9/5
equation is
y = -3/5x + 9/5

What do we mean by a triangle's congruency?If all three corresponding sides and angles of two triangles are the same size, they are said to be congruent.These triangles can be moved, rotated, flipped, and turned to appear identical.If they are moved, they will coincide.When two triangles satisfy the five congruence conditions, congruence exists.They are the side-side-side (SSS), side-angle-side (SAS), angle-side-angle (ASA), angle-angle-side (AAS), and right angle-hypotenuse-side (RHS).So,
Given:
∠A and ∠C are right angles.∠ABE ≅ ∠CBD, AE ≅ CDSo, we can say that △ABE ≅ △CBD is under AAS condition.

The arithmetic mean a n of the given terms a n₋₁ = 0.3, a n₊₁ = 1.9 is
a n = 1.6.
What is direct variation?
a n₋₁ = 0.3, a n₊₁ = 1.9
a n = a [tex]n_{+1}[/tex] - a[tex]n_{-1}[/tex]
a n = 1.9 - 0.3
a n = 1.6
Direct variation is the change in one quantity as a result of the change in another. This suggests that if one quantity rises or falls, the other must rise or fall correspondingly as well.
The formula y = kx is used to answer direct variation questions. If finding the proportionality constant is necessary, the answer is obtained by dividing y by x.

How can you determine whether two variables x and y for a real-life situation are, correlated?
To determine if two variables, X and Y, are correlated, we can use the two simple ways. One is to create a scatter plot simply—a scatter plot plots X and Y pair values. A scatter plot shows a diagram of correlations. We can also identify if the correlation formed is positive, negative, or non-existent. Calculating the correlation coefficient R and determining its p-value associated with R is also possible.
Correlation coefficient values are always between -1 and 1.

Where did the formula for summing finite geometric series come from? Suppose the geometric series has first term a₁ and constant ratio r , so that S n= a₁ + a₁r+ a₁ r²+ . . +a₁ rⁿ⁻¹
a. Show that r S n = a₁r+ a₁ r²+ a₁ r³+ . . . . +a₁rⁿ .
The total of a geometric series is an unlimited number of terms with a fixed ratio between them.
If S n= a₁ + a₁r+ a₁ r²+ . . +a₁ rⁿ⁻¹ then rSn = a₁r + a₁ r²+ . . +a₁ rⁿ⁻¹+a₁ rⁿ.
What is the formula for geometric series?
The sum of a geometric series Sn is given by:
[tex]$S_n=a(\frac{1-r^{n} }{1-r} )[/tex]
Given:
Sum of first n terms of the Geometric progression be
Sn = a₁ + a₁r + a₁ r² + . . + a₁ rⁿ⁻¹ ---(1)
On multiplying by r on both sides,
r Sn = a₁r + a₁ r² + . . + a₁ rⁿ⁻¹ + a₁ rⁿ ----(2)
So, (2) − (1) gives,
[tex]rS_n-S_n=ar^{n} -a[/tex]
[tex]S_n(r-1)=a(r^{n} -1)[/tex]
Therefore, the sum of n terms of a GP is:
[tex]$S_n=a(\frac{1-r^{n} }{1-r} )[/tex]
Let the expression be r S n = a₁r + a₁ r² + a₁ r³ + . . . . + a₁rⁿ
Sum of first n terms of the Geometric progression is:
Sn = a₁ + a₁r + a₁ r² + . . + a₁ rⁿ⁻¹
On multiplying by r on both sides, we get
rSn = a₁r + a₁ r²+ . . +a₁ rⁿ⁻¹+a₁ rⁿ
Therefore, rSn = a₁r + a₁ r²+ . . +a₁ rⁿ⁻¹+a₁ rⁿ

The equation of the line parallel and perpendicular are y = -0.9(x+7) and y = 10/9(x+7) respectively
Equation of a lineThe equation of a line in point slope form is expressed as;

The first ten terms of the Fibonacci sequence are 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and so on.
What is Fibonacci sequence and what are the first ten terms?The Fibonacci numbers, sometimes known as Fn in mathematics, are a series of numbers. Each number in the Fibonacci sequence is composed of the sum of the two numbers before it. Typically, the sequence begins with 0 and 1.
means
0 + 1 = 1
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
5 + 8 = 13
8 + 13 = 21
13 + 21 = 34
21 + 34 = 55
34 + 55 = 89

By looking at the graph:
Domain: (-6, 1] U (1, 5]
Range: (-3, 2] U [3, 7)
How to find the domain and range of the graphed function?
The domain is the set of inputs (horizontal axis) and the range is the set of the outputs (vertical axis).
By looking at the horizontal axis we can see that the first part goes from x = -6 to x = -1, this interval is (-6, 1]
(at x = -6 there is a open circle, so x = -6 does not belong to the domain)
Similarly, the second interval is (1, 5]
Then the domain is D: (-6, 1] U (1, 5]
