Consider a sequence defined similarly to the Fibonacci, but with a slight twist:
f(n) = f(n-1)-f(n-2) with f(1) = 2 and f (2) = 5
Generate terms f (3), f(4), f(5), f(6), f(7), and f(8). Then, determine the value of f(25).
A sequence can be arithmetic, geometric, and it can take several other forms such as Fibonacci.
The values of f(3), f(4), f(5), f(6), f(7), and f(8) are 3, -2, -5, -3, 2, 5The value of f(25) is 2The given parameters are;
[tex]\mathbf{f(n) = f(n-1)-f(n-2)}[/tex]
[tex]\mathbf{f(1) = 2 }[/tex]
[tex]\mathbf{f(2) = 5 }[/tex]
Calculate f(3), f(4), f(5), f(6), f(7), and f(8).
Substitute 3 for n in [tex]\mathbf{f(n) = f(n-1)-f(n-2)}[/tex]
[tex]\mathbf{f(3) = f(3-1)-f(3-2)}[/tex]
[tex]\mathbf{f(3) = f(2)-f(1)}[/tex]
[tex]\mathbf{f(3) = 5-2}[/tex]
[tex]\mathbf{f(3) = 3}[/tex]
Following the above sequence, we have:
[tex]\mathbf{f(4) = f(3)-f(2)}[/tex]
[tex]\mathbf{f(4) = 3-5}[/tex]
[tex]\mathbf{f(4) = -2}[/tex]
[tex]\mathbf{f(5) = f(4)-f(3)}[/tex]
[tex]\mathbf{f(5) =-2- 3}[/tex]
[tex]\mathbf{f(5) = -5}[/tex]
[tex]\mathbf{f(6) = f(5)-f(4)}[/tex]
[tex]\mathbf{f(6) =-5- -2}[/tex]
[tex]\mathbf{f(6) = -3}[/tex]
[tex]\mathbf{f(7) = f(6)-f(5)}[/tex]
[tex]\mathbf{f(7) =-3--5}[/tex]
[tex]\mathbf{f(7) = 2}[/tex]
[tex]\mathbf{f(8) = f(7)-f(6)}[/tex]
[tex]\mathbf{f(8) =2--3}[/tex]
[tex]\mathbf{f(8) = 5}[/tex]
Hence, the values of f(3), f(4), f(5), f(6), f(7), and f(8) are 3, -2, -5, -3, 2, 5
Then, determine the value of f(25).
In (1), we have:
[tex]\mathbf{f(3) = 3}[/tex]
[tex]\mathbf{f(4) = -2}[/tex]
[tex]\mathbf{f(5) = -5}[/tex]
[tex]\mathbf{f(6) = -3}[/tex]
[tex]\mathbf{f(7) = 2}[/tex]
[tex]\mathbf{f(8) = 5}[/tex]
This means that:
[tex]\mathbf{f(n) = -f(n-3i)}[/tex]
Where i is greater than 0
Substitute 25 for n
[tex]\mathbf{f(25) = -f(25-3i)}[/tex]
Let i = 7.
So, we have:
[tex]\mathbf{f(25) = -f(25-3 \times 7)}[/tex]
[tex]\mathbf{f(25) = -f(25-21)}[/tex]
[tex]\mathbf{f(25) = -f(4)}[/tex]
So, we have:
[tex]\mathbf{f(25) = -(-2)}[/tex]
[tex]\mathbf{f(25) = 2}[/tex]
Hence, the value of f(25) is 2

why is the order you use to name polygons important when writing a congruency statement?
Answer:
When stating that two triangles are congruent, use a congruence statement. The order of the letters is very important, as corresponding parts must be written in the same order. Notice that the congruent sides also line up within the congruence statement. One congruence statement can always be written six ways.

which of these figures has rotational symmetry?
Answer: Choice C
We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.
The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. The correct option is C.
What is Rotational Symmetry?The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. When turned 180 degrees or with specific angles, clockwise or anticlockwise, many geometrical forms appear to be symmetrical. Examples include squares, circles, hexagons, and more.
The shape that has a rotational symmetry is option C, which is a parallelogram.

A ___ thermometer has a liquid that _____ and rises in a ____ tube when it's temperature goes up; the liquid ___ and it's level drops when the temperature goes down.
Answer:
The answer is "bulb, expands, and glass ".
Step-by-step explanation:
The bulb thermometer is the common glass temperature sensor for which you might be grown up. This thermometer is filled with a liquid, typically mercury. Bulb thermometers work on the simple premise that it volume of the liquid varies in proportion to its volume.
It is a glass tube that is pre full with a fluid such as a hydrogen or liquor and is sealed at both sides. The fluid in the glass tube rises as the mercury inside the thermometer's bulb increases. When the temperature gauge is warm, the liquid inside flows up in the tube.

A contracting company rents a generator for 6 hours and a heavy duty saw for 6 hours total cost of $48 for another job the company rents the generator for 4 hours and the saw for 8 hours for a total cost of $40 find the hourly rates
Answer:
the hourly rates are $8 and $10 respectively
Step-by-step explanation:
Given that
The generator rents for 6 hours and the total cost is $48
And, for another job The generator rents for 4 hours and the total cost is $40
We need to find out the hourly rates
For the first one
= $48 ÷ 6 hours
= $8
For the second one
= $40 ÷ 4 hours
= $10
Hence, the hourly rates are $8 and $10 respectively

What is the value of x applicable to this problem?
What is the length and width of the window?
URGENT
Answer:
sides are of 16 in
Step-by-step explanation:
here's your solution
==> area of square = 256 in^2. [given]
==> side of square = 4x
==> area of square= side^2
==> 4x^2 = 256
==> 16x^2 = 256

1. What is the length of the hypotenuse of a right triangle with legs of length 80 feet and 150 feet? Show
all algebraic work for full credit.
Answer:
80^2 + 150^2
6400 + 22500 = 28,900
Something squared will equal 28,900
170^2 = 28,900
170 is your answer!
The length of the hypotenuse of the right triangle with legs of 80 feet and 150 feet is 170 feet.
How to determine the hypotenuse of the triangle?To find the length of the hypotenuse of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
In this case, the legs of the triangle have lengths of 80 feet and 150 feet, so we can label them as follows:
Leg 1: a = 80 feet
Leg 2: b = 150 feet
We can then use the Pythagorean theorem to solve for the length of the hypotenuse, which we can label as c:
c² = a² + b²
Substituting in the values for a and b, we get:
c² = (80 feet)² + (150 feet)²
c² = 6,400 square feet + 22,500 square feet
c² = 28,900 square feet
c = √(28,900 square feet)
c = 170 feet
Therefore, the length of the hypotenuse of the right triangle with legs of 80 feet and 150 feet is 170 feet.
