Step-by-step explanation:
- The Fibonacci Sequence is the series of numbers:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
- The next number is found by adding up the two numbers before it
# Example:
- The 2 is found by adding the two numbers before it (1+1)
- The 3 is found by adding the two numbers before it (1+2),
- The 5 is (2+3) and so on
- The rule of it is x(n) = x(n-1) + x(n-2) where
# x(n) is term number ⇒ n
# x(n-1) is the previous term ⇒ (n-1)
# x(n-2) is the term before that ⇒ (n-2)
- Example: the 8th term is the 7th term plus the 6th term:
x(8) = x(7) + x(6)
# Note: When we take any two consecutive Fibonacci Numbers,
their ratio is very close to the Golden Ratio φ
- The Golden Ratio φ is approximately 1.618034...
- We can calculate any Fibonacci Number using the Golden Ratio:
x(n) = [φ^n - (1 - φ)^n]/√5
- The answer is a whole number, exactly equal to the addition of the
previous two terms.
# There is an interesting patterns in Fibonacci sequence:
every nth number is a multiple of x(n)
- Example:
* x3 = 2 ⇒ every 3rd number is a multiple of 2 (2, 8, 34, 144, 610, ...)
* x4 = 3 ⇒ Every 4th number is a multiple of 3 (3, 21, 144, ...)
* x5 = 5 ⇒ Every 5th number is a multiple of 5 (5, 55, 610, ...)
- The man who invented it.
His real name was Leonardo Pisano Bogollo, and he lived between
1170 and 1250 in Italy.
- Fibonacci was his nickname
- Fibonacci sequence is it used for:
# Reflects patterns of growth spirals (a spiral curve , shape , pattern ,
object) found in nature
# It is the closest approximation in integers to the logarithmic spiral
series, which follows the same rule as the Fibonacci sequence
The Fibonacci sequence is a series of numbers important in mathematics and nature, introduced to European mathematics by Leonardo of Pisa, also known as Fibonacci. It describes various natural phenomena, appears in plants' growth patterns, contributes to arts and sciences, and has practical uses in algorithms and market analysis.
Explanation:The Fibonacci sequence is a series of numbers where a number is found by adding up the two numbers before it. Starting with 0 and 1, the sequence goes 0, 1, 1, 2, 3, 5, 8, 13, 21, and so forth. This mathematical concept was brought to European mathematics by Leonardo of Pisa, known as Fibonacci. He described this sequence in his book 'Liber Abaci' in 1202, although the sequence had been previously described in Indian mathematics.
The Fibonacci sequence is not just a number theory curiosity but has many applications and appears in the natural world. Notably, it is used to describe various phenomena in quantum computing, stock market analysis, and in nature, such as the branching of trees, the arrangement of leaves on a stem, or the fruitlets of a pineapple. In the context of spirals and botany, the mechanism of the spirals of plants follows the Fibonacci sequence, as explored in resources like 'Doodling in Math: Spirals, Fibonacci, and Being a Plant' by Vihart and 'How to Count the Spirals' by MoMath: National Museum of Mathematics.
The Fibonacci sequence also finds itself being applied to areas such as computer algorithms, especially in recursive algorithms where an operation needs to be repeated on a smaller scale. It also helps build a bridge between mathematics and the arts, showing how mathematics can inspire beautiful patterns and structures in man-made and natural art forms. The prevalence of the Fibonacci sequence and the golden ratio in aesthetic compositions demonstrates the union between form and number that fascinates both mathematicians and artists alike.

2
4
35
70
Answer:
The answer is 4.
Step-by-step explanation:
I believe that, if I'm correct, 2 students are equal to 1%. 2 x 35 = 70. 2 x 33 = 66. 70 - 66 = 4 more students. I hope this is correct.
The total number of students who preferred apples than cherries are 70 if the two hundred students were surveyed about their favorite fruit option, fourth is correct.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
From the diagram, we can see the total 35% students preferred apples.
Total number of students = 200
The number of students who preferred apples than cherries = 200×35%
= 200(35/100)
= 2(35)
= 70
Thus, the total number of students who preferred apples than cherries are 70 if the two hundred students were surveyed about their favorite fruit option fourth is correct.

Answer:
52 ft
Step-by-step explanation:
For each chord, the product of segment lengths is a constant. We can find that constant as the product of the segment lengths of the bisected chord:
(24 ft)·(24 ft) = 576 ft^2
Then the missing segment length (DX) of the diameter chord is ...
DX·(36 ft) = 576 ft^2
DX = (576 ft^2)/(36 ft) = 16 ft
So, the total length of the diameter chord is ...
DX +XL = 16 ft + 36 ft
DL = 52 ft
_____
We know DL is a diameter because the perpendicular bisector of any chord intersects the center of the circle.

Antoine has $18.20 to spend on some oranges and a pumpkin. Oranges cost
$1.30 per pound, and a pumpkin costs $5.20
The inequality 1.30x + 5.20 18.20 models this situation, where x is the
number of pounds of oranges.
Solve the inequality. How many pounds of oranges can Antoine buy?
Answer:
10 pounds
Step-by-step explanation:
You forgot the inequality sing, but since Antoine can't spend more than $18.20, I am positive that the sign is [tex]\leq[/tex] (Antony can spend $18.20 or less than $18.20).
Therefore, our inequality is: [tex]1.30x+5.20\leq 18.20[/tex]
where [tex]x[/tex] is the pounds of oranges
Let's solve step-by-step to find how many pounds of oranges he can buy
Step 1. Subtract 5.20 fro both sides of the inequality
[tex]1.30x+5.20-5.20\leq 18.20-5.20[/tex]
[tex]1.30x\leq 13[/tex]
Step 2. Divide both sides of the inequality by 1.30
[tex]\frac{1.30x}{1.30} \leq \frac{13}{1.30}[/tex]
[tex]x\leq 10[/tex]
We can conclude that Antony can buy 10 pounds of oranges.

Madame Pickney has a rather extensive art collection and the overall value of her collection has been increasing each year. Three years ago, her collection was worth $600,000. Two years ago, the value of the collection was $690,000 and last year, the collection was valued at $793,500.
Assume that the rate at which Madame Pickney’s art collection’s value increase remains the same as it has been for the last three years. The value of the art collection can be represented by a geometric sequence. The value of the collection three years ago is considered the first term in the sequence.
What explicit rule can be used to determine the value of her art collection n years after that?
Answer:
an = 600,000 (1.15)^(n-1)
Step-by-step explanation:
So the first year, a₁ = 600,000. The next year, a₂ = 690,000. So:
r = a₂ / a₁
r = 690,000 / 600,000
r = 1.15
So an = 600,000 (1.15)^(n-1).

A box plot is also known as a(n) box-and-whisker plot. Use the box plot below to find each of the following.
Minimum: _____
First quartile: _____
Median: _____
Third quartile: _____
Maximum: _____
Answer:
the min is 53 the max is 90 median is 65 first quartile is 60 and the third quartile is 82
Step-by-step explanation:
The correct answers are: Minimum: 53, First quartile: 60, Median: 65, Third quartile: 82, Maximum: 90.
To read a box plot, we look at the five-number summary: the minimum, first quartile, median, third quartile, and maximum.
The box plot shows the middle 50% of the data, which is the interquartile range (IQR). The IQR is represented by the box, with the median represented by the line inside the box.
The whiskers extend from the box to the minimum and maximum values, respectively.
In this box plot, the minimum value is 53 and the maximum value is 90. The IQR is 65 - 60 = 5, which means that the middle 50% of the data is within 5 points of the median. The median is 65, so the first quartile is 60 and the third quartile is 82.

(PLEASEEE dont ignore, need help) ❗️⚠️ State whether the two triangles are similar. If so, write a similarity statement and tell if they are similar by AA, SSS, or SAS
Answer:
Step-by-step explanation:
For 2 triangles to be similar, they have to have congruent angle measures with corresponding sides that exist in proportion to one another. #14 shows a triangle with 2 angle measures given. We can find the third angle in that triangle to be 65. The one on the right in #14 shows a triangle with 66 degrees in the position corresponding to 65 on the left. Those are not similar (we know nothing about the side lengths so we have no choice but to work with the angles).
#15 shows 2 triangles that are "attached" by angle M in the center. Those 2 angles meet to create vertical angles, and vertical angles are congruent, so angle HMG and angle KMJ are congruent. If both triangles have 2 angles that are corresponding and congruent, then the third angles in both will also be guaranteed to be congruent. So those 2 triangles are similar by AA
One number is 4 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 538, find the numbers
Answer:
73
292
173
Step-by-step explanation:
x = first number
4x = second number
100 + x = third number
x + 4x + 100 + x = 538
6x + 100 = 538
6x + 100 - 100 = 538 - 100
6x = 438
6x/6 = 438/6
x = 73
Check:
73 + 4(73) + 100 + 73 = 538
73 + 292 + 173 = 538
538 = 538
Answer:
The numbers are 73, 173 and 292.
Step-by-step explanation:
If the numbers are x, y and z we have:
y = 4x
z = x + 100
x + y + z = 538
Substituting for y in the last equation:
x + 4x + z = 538
5x + z = 538.............(1)
From the second equation:
z - x = 100................(2)
Equation (1) - (2) gives:
6x = 438
x = 73
Therefore y = 4x) = 4(73) = 292
and z = x + 100 = 73 + 100 = 173.

This is a case of enlargement of a figure of scale factor [tex]\frac{1}{3}[/tex].
In any enlargement, [tex]Area(F')=k^2 Area(F)[/tex], where the transformation maps F onto F'.
In this case, let F be polygon XXX and let F' be polygon YYY. Hence,
[tex]Area(YYY) = k^2 Area (XXX)[/tex]
[tex]Area(YYY) = (\frac{1}{3})^2 Area(XXX)[/tex]
[tex]Area(YYY) = \frac{1}{9} Area(XXX)[/tex]
Therefore, the area of polygon YYY is [tex]\frac{1}{9}[/tex] of the area of polygon XXX.

The area of a right triangle with side lengths 7 and 7 is [tex]\frac{bh}{2} = \frac{7*7}{2} = \frac{49}{2} = 24.5[/tex]
Answer: ≈ 13.98 in2
Step-by-step explanation:
A segment of a circle is a region bounded by an arc and its chord.
To determine the area of the segment, begin by finding the area of the sector defined by the central angle.
A sector of a circle is a region bounded by two radii of the circle and their intercepted arc.
The formula for the sector area is A = πr2 (m∘/360∘).
It is given in the figure that central angle MNO is a right angle. So, m∠MNO = 90∘. It is also given that r = 7 in.
Substitute the given values into the formula and simplify.
A = π(7)2 (90∘/360∘) = 49/4π in2
Find the area of △MNO.
Since the radii in a circle are congruent, NO = NM = 7. To find the area of △MNO, use the formula for the area of a triangle, A = 1/2bh.
Substitute 7 for b and 7 for h, then simplify.
A = 1/2 (7) (7) = 24.5 in2
The area of the segment is the difference between the two areas, the area of the sector and the area of the triangle.
A = 49/4π − 24.5 ≈ 13.98 in2
Therefore, the area of segment MNO is ≈ 13.98 in2.

∵ a/b ÷ c/d
- To solve it change the division sign to multiplication sign and
reciprocal the fraction after the sign
∴ a/b × d/c = ad/bc

- Lets take the denominator and simplify by make it a single
fraction, let the denominator of it 2x and change
the numerator
∴ [tex]\frac{x^{2}}{2}+\frac{2}{x}=\frac{x(x^{2})+2(2)}{(2)(x)}=\frac{x^{3}+4}{2x}[/tex]
∴ The fraction = [tex]\frac{\frac{3x-7}{x^{2}}}{\frac{x^{3}+4}{2x}}[/tex]
* Now lets change it by (up ÷ down)
∴ [tex]\frac{3x-7}{x^{2}}[/tex] ÷ [tex]\frac{x^{3}+4}{2x}[/tex]
- Change the division sign to multiplication sign and reciprocal
the fraction after the sign
∴ [tex]\frac{3x-7}{x^{2}}[/tex] × [tex]\frac{2x}{x^{3}+4}[/tex]
∴ [tex]\frac{(2x)(3x-7)}{(x^{2})(x^{3}+4)}[/tex]
- We can simplify x up with x down
∴ [tex]\frac{2(3x-7)}{x(x^{3}+4)}[/tex]

Find the values of x and y when the smaller triangle shown here has the given area.
The values of x and y, when the smaller triangle has an area of 10 cm² are x = 4cm and y = 5cm.
Explanation:In the given triangle, the area can be expressed as [tex]\( \frac{1}{2} \times x \times y \)[/tex], where x and y represent the base and height of the triangle, respectively. Since the area is given as 10 cm², the equation becomes [tex]\( \frac{1}{2} \times x \times y = 10 \)[/tex].
To find x and y, we can rearrange the equation:
[tex]\[ x \times y = \frac{10 \times 2}{1} \][/tex]
[tex]\[ x \times y = 20 \][/tex]
Now, we need to find two numbers whose product is 20. The pair x = 4 and y = 5 satisfies this condition, as 4 × 5 = 20. Therefore, the values of x and y that satisfy the given area are x = 4cm and y = 5cm.
In conclusion, the solution x = 4cm and y = 5cm satisfies the given area condition. This is determined by substituting these values into the area formula, resulting in an area of 10 cm².

In a train yard, there are 6 flat cars, 7 boxcars, and 3 livestock cars. A train is made up of 9 cars. Which would you use to find the number of ways the train could be made up?
A. 16P9
B. 16P7
C. 9P16
D. 9P7
Answer:
Option A
Step-by-step explanation:
In a train yard there are 6 flat cars, 7 box-cars and 3 livestock cars.
So total number of cars = 6 + 7 + 3
= 16
Now a train is to be made by 9 cars, out of 16 cars.
So number of ways the train can be made up will be =[tex]^{n}P_{r}[/tex]
where n = 16 and r = 9
so number of ways =[tex]^{16}P_{9}[/tex]
Option A is the answer.
Considering the definition of permutation, you use 16P9 to find the number of ways the train could be made up. (Option A).
What is PermutationPermutation is placing elements in different positions. So, permutations of m elements in n positions are called the different ways in which the m elements can be arranged occupying only the n positions.
That is, permutations refer to the action of arranging all the members of a set in some sort of order or sequence.
In other words, permutations (or Permutations without repetition) are ways of grouping elements of a set in which:
take all the elements of a set.the elements of the set are not repeated.order matters.To obtain the total of ways in which m elements can be placed in n positions, the following expression is used:
[tex]mPn=\frac{m!}{(m-n)!}[/tex]
where "!" indicates the factorial of a positive integer, which is defined as the product of all natural numbers before or equal to it.
This caseIn a train yard there are 6 flat cars, 7 box-cars and 3 livestock cars. So total number of cars is 6 + 7 + 3= 16.
A train is made up of 9 cars, out of 16 cars.
To obtain the total of ways in which 16 elements can be placed in 9 positions, you use the permutation 16P9.
Finally, you use 16P9 to find the number of ways the train could be made up. (Option A).

graph the equation by plotting three points. if all three are correct, the line will appear.
-3y=5x-7
Answer:
(x, y) = (-1, 4), (2, -1), (5, -6)
Step-by-step explanation:
You can choose any value you like for either x or y, then solve for the other value. I like to plot points with integer coefficients, so I would look for sets of those.
The nature of this equation is that it will have integer solutions with x-values spaced 3 apart and y-values spaced 5 apart. (The spacing of each corresponds to the coefficient of the other.) So, the trick is to find an x-value that gives an integer solution for y. (You will need to try at most 3 consecutive integers.)
Solving the equation for y, we get ...
y = -5/3x +7/3
Right away, we know that x=0 will not give an integer solution for y. Nor does x=1. The third consecutive integer that is easy to try is x = -1, so ...
y = (-5/3)(-1) +7/3 = (5+7)/3 = 4 . . . . an integer value for y
Our first point is then (x, y) = (-1, 4).
Since the slope is negative, we know that increasing x will decrease y. Thus we can simply add (3, -5) to any point to get another point on the line.
Two more points on the line are ...
(-1, 4) +(3, -5) = (2, -1)
(2, -1) +(3, -5) = (5, -6)
Three integer-valued points on this line are (-1, 4), (2, -1), (5, -6).

Please help me with this..
Answer:
w = 93°
Step-by-step explanation:
The angle with measure 142° forms a straight angle with the third angle in the triangle and are supplementary, thus
third angle = 180° - 142° = 38°
The sum of the 3 angles in the triangle = 180°
w = 180° - (38 + 49)° = 180° - 87° = 93°

Polygon ABCDE has the vertices A(2, 8), B(4, 12), C(10, 12), D(8, 8), and E(6, 6). Polygon MNOPQ has the vertices M(-2, 8), N(-4, 12), O(-10, 12), P(-8, 8), and Q(-6, 6).
A transformation or sequence of transformations that can be performed on polygon ABCDE to show that it is congruent to polygon MNOPQ is a
If polygon MNOPQ is translated 3 units right and 5 units down, it will coincide with a congruent polygon, VWXYZ, with its vertices at
Answer:
1). Option C
2). Option A
Step-by-step explanation:
The given vertices of polygon ABCDE are A(2, 8), B(4, 12), C(10, 12), D(8, 8) and E(6, 6)
After reflection new polygon formed MNOPQ has the vertices M(-2, 8), N(-4, 12), O(-10, 12), P(-8, 8) and Q(-6, 6).
By comparing the vertices we find the x-coordinates of polygon ABCDE have been changed to MNOPQ by negative notation only.Y- coordinates are same.
Therefore, polygon ABCDE has been reflected across the y-axis.
Option C. is the answer.
If polygon MNOPQ is translated 3 units right and 5 units down then the new vertices of congruent polygon VWXYZ will be
M(-2, 8) = [(-2 - 3), (8 + 5)] = (-5, 13)
N(-4, 12) = [(-4 - 3), (12 + 5)] = (-7, 17)
O(-10, 12) = [(-10 - 3),(12 + 5)] = (-13, 17)
P(-8, 8) = [(-8 - 3), (8 + 5)] = (-11, 13)
Q(-6, 6) = [(-6 -3),(6 + 5)] = (-9, 11)
Therefore, Option A. is the correct option.
