what is arithmetic progression ?An algebraic progression is when there is a continual difference between terms that follow each other in an series. For illustration, the decimal number 5, 7, 9, 11, 13, and 15 is an example of an algebraic expression with a tolerance of two. A advance with a set tolerance among any two consecutive numbers is referred to as a "arithmetic progression" (A.P.). Two types of algebraic progression are plausible: series in mathematics with a finite length A finite geometric evolution is a series with just a finite number of terms. The early, late, allowance, and frequency of terms may all be calculated using the terms in the series.
given
a1 = 3
a2 = 5 * 3 + 1 = 16
a3 = 5 * 16 + 1 = 81
a4 = 5* 81 + 1 = 406

a library has 2500 books.40% of the books are fiction.How many books are not fiction books
A library has 2500 books.40% of the books are fiction, number of not fiction books are 1500.
A percentage is a relative figure that represents one tenth of a quantity. Since one percent (symbolised as 1%) is equal to one tenth of anything, 100 percent stands for everything, while 200 percent refers to double the amount specified.
Total amount of book in library are 2500 ,
Out of that 40% are fiction so the number of the non fiction books are 60%
so 60% of 2500 will give us the value of non fiction books,
Number of non fiction = 2500 x 60%
= 2500 x 60/100
= 25 x 60
= 1500

$2,250 was invested at 2% and the remaining $3,500 was invested at 12%. The combined interest earned amount for the first year was $475.
The financial planner invested $5,750 of the couple's money. Let x be the amount of money invested in the savings account paying 2% annual simple interest and y be the amount of money invested in the riskier mini-mall development plan paying 12% annual simple interest. Since the combined interest earned for the first year was $475, we can write the equation 2x + 12y = 475. Since the total amount of money invested was $5,750, we can add the equation x + y = 5,750 to our system of equations. Solving the system of equations yields x = 2,250 and y = 3,500. Thus, $2,250 was invested at 2% and the remaining $3,500 was invested at 12%. The combined interest earned for the first year was $475.

A (4,0).B (1.5), and C(-3,-5) are three vertices of a parallelogram ABCD. What is the ordered pair for D, the fourth vertex of the parallelogram?
Answer: In a parallelogram, opposite sides are equal in length and parallel, so if we subtract the vectors AB and BC from each other, we will get the vector for CD.
Given A = (4,0), B = (1.5,0), and C = (-3,-5), we can calculate the vectors AB and BC as follows:
AB = B - A = (1.5, 0) - (4, 0) = (-2.5, 0)
BC = C - B = (-3, -5) - (1.5, 0) = (-4.5, -5)
Next, we subtract these vectors to find the vector for CD:
CD = BC - AB = (-4.5, -5) - (-2.5, 0) = (-2, -5)
Finally, we add the vector CD to vertex C to find vertex D:
D = C + CD = (-3, -5) + (-2, -5) = (-5, -10)
So, the ordered pair for vertex D is (-5, -10).

Given f(x)=4(x−2)^3+2, classify each statement about f^−1(x) as true or false.
Choose the answers which are correct or false.
1. The point of symmetry on f^−1(x) is (2,2).
2. The domain of f^−1(x) is (−∞,4).
3. The graphs of f^−1(x) and f(x) are reflections across the line y = x
4. f^−1(x) is not a function.
Answer:
1. True
2. False
3. True
4. False
Step-by-step explanation:
Given function:
[tex]f(x)=4(x-2)^3+2[/tex]
1. Point of SymmetryThe point-of-symmetry of a cubic graph is its point of inflection.
To find the x-value of the point of inflection of a cubic function, differentiate the function twice:
[tex]f'(x)=12(x-2)^2[/tex]
[tex]f''(x)=24(x-2)[/tex]
Set the second differentiated function to zero and solve for x:
[tex]\implies 24(x-2)=0[/tex]
[tex]\implies x-2=0[/tex]
[tex]\implies x=2[/tex]
Substitute the found value of x into the original function to find the y-value of the point of inflection:
[tex]\implies y=4(2-2)^3+2[/tex]
[tex]\implies y=4(0)^3+2[/tex]
[tex]\implies y=0+2[/tex]
[tex]\implies y=2[/tex]
Therefore, the point of symmetry of the cubic function is (2, 2).
The inverse of a cubic function its reflection in the line y = x.
As the point of symmetry is (2, 2), then its reflection in the line y = x is also (2, 2).
So the point of symmetry on f⁻¹(x) is (2, 2).
2. DomainThe given function has an unrestricted domain and range.
Domain of f(x): (-∞, ∞) → all real numbersRange of f(x): (-∞, ∞) → all real numbersThe domain of the inverse function is the range of the function.
The range of the inverse function is the domain of the function.
Therefore, as the domain and the range of the original function are unrestricted, so are the domain and range of the inverse function.
Domain of f⁻¹(x): (-∞, ∞) → all real numbersRange of f⁻¹(x): (-∞, ∞) → all real numbers3. Reflection across the line y = xThe inverse of a cubic function with an unrestricted domain is its reflection across the line y = x.
Therefore, the graphs of f⁻¹(x) and f(x) are reflections across the line y = x.
4. Inverse functionTo find the inverse of the given function, swap x and y:
[tex]\implies x=4(y-2)^3+2[/tex]
Rearrange to make y the subject:
[tex]\implies x-2=4(y-2)^3[/tex]
[tex]\implies \dfrac{x-2}{4}=(y-2)^3[/tex]
[tex]\implies \sqrt[3]{\dfrac{x-2}{4}}=y-2[/tex]
[tex]\implies y=\sqrt[3]{\dfrac{x-2}{4}}+2[/tex]
Replace y with f⁻¹(x):
[tex]\implies f^{-1}(x)=\sqrt[3]{\dfrac{x-2}{4}}+2[/tex]
As we have already established, the domain and range of the inverse function are unrestricted. As each x-value has only one y-value associated with it, f⁻¹(x) is a function.

Polygon ABCD is drawn with vertices A(−4, −4), B(−4, −6), C(−1, −6), D(−1, −4). Determine the image coordinates of C′ if the preimage is reflected across y = 4.
C′(−3, 6)
C′(−3, 14)
C′(−1, 6)
C′(−1, 14)
Answer:
(d) C'(-1, 14)
Step-by-step explanation:
You want the coordinates of C' after the point C(-1, -6) is reflected across the line y = 4.
ReflectionReflection across the horizontal line y=4 will not change the x-coordinate of the point, so C' has an x-coordinate of -1.
The point (-1, 4) on the line of reflection will be the midpoint of C and C', so we have ...
(C +C')/2 = (-1, 4)
C +C' = 2(-1, 4) = (-2, 8) . . . . .multiply by 2
C' = (-2, 8) -C
C' = (-2, 8) -(-1, -6) = (-1, 8+6)
C' = (-1, 14)
__
Additional comment
Effectively, the reflection across the line y=4 is the transformation ...
(x, y) ⇒ (x, 8 -y)
Answer:
C'(-1, -6).
Step-by-step explanation:
the reflection across y = 4 for point C(-1, -6).
When reflecting a point across a horizontal line like y = 4, the y-coordinate remains the same, and the x-coordinate is inverted with respect to the line of reflection.
For point C(-1, -6), the y-coordinate remains -6, and the x-coordinate is inverted across y = 4:
New x-coordinate = -1
So, the reflected image of point C across y = 4 is C'(-1, -6).
None of the provided options match this reflection, so it seems there might be an error in the given answer choices. The correct reflection of point C(-1, -6) across y = 4 is C'(-1, -6).

Let x be the number of biology textbooks sold. Then, the number of psychology textbooks sold was x - 61.
The combined total of the two types of textbooks sold was 251, so we can write an equation:
x + (x - 61) = 251
Expanding the right side:
2x - 61 = 251
Adding 61 to both sides:
2x = 312
Dividing both sides by 2:
x = 156
the number of psychology textbooks sold = x - 61
= 156 - 61
= 95
So, 156 biology textbooks were sold and 95 psychology textbooks were sold.
