Can we write a formula for the general term Un of the Fibonacci Sequence?
The general term formula for the Fibonacci sequence would be [tex]F_n=\frac{1}{\sqrt{5}}((\frac{1+\sqrt{5}}{2})^n - (\frac{1-\sqrt{5}}{2})^n)[/tex].
What is a Fibonacci Sequence?
The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones, starting from 0 and 1. The sequence goes as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, and so on.
The Fibonacci sequence is given by
[tex]F_n-F_{n-1}-F_{n-2}=0[/tex]
So its characteristic polynomial is
[tex]x^2-x-1=0[/tex]
The roots of this are
[tex]\alpha=\frac{1+\sqrt{5}}{2}\\\\\beta=\frac{1-\sqrt{5}}{2}[/tex]
Each with multiplicity one. Hence,
[tex]F_n=A\alpha^n + B\beta^n\\\\\For $ F_1=1 $ $and $ $ F_2=1$\\\\A=1/\sqrt{5} \\\\B=-1/\sqrt{5}[/tex]
Thus,
[tex]F_n=\frac{1}{\sqrt{5}}((\frac{1+\sqrt{5}}{2})^n - (\frac{1-\sqrt{5}}{2})^n)[/tex]
Hence, the general term formula for the Fibonacci sequence would be [tex]F_n=\frac{1}{\sqrt{5}}((\frac{1+\sqrt{5}}{2})^n - (\frac{1-\sqrt{5}}{2})^n)[/tex].

Please help me with #8 and 9
Answer:
8. TN = 22 units
9. RT = √(165) units
Step-by-step explanation:
It appears that point T is the circumcenter of triangle MNP.
A circumcenter of a triangle is:
The center of a circle that passes through each vertex of a triangle. The point at which the perpendicular bisectors of the sides of the triangle intersect.As a perpendicular bisector is a line that divides another line segment into two equal parts at a right angle, then:
MR = RNNS = SPPQ = QMAs point T is the circumcenter, ΔMTN, ΔNTP and ΔMTP are isosceles triangles and MT, TP and TN are the radius of the circumcircle.
Therefore:
MT = TP = TNQuestion 8To find the length of TN, find the value of x by equating the given expressions for MP and TP:
[tex]\implies \sf MT = TP[/tex]
[tex]\implies 6x - 56 = 3x - 17[/tex]
[tex]\implies 3x = 39[/tex]
[tex]\implies x = 13[/tex]
Substitute the found value of x into the expression for TP:
[tex]\implies \textsf{TP} = 3(13) - 17[/tex]
[tex]\implies \textsf{TP} = 22[/tex]
Therefore, as TN = TP then TN = 22 units.
Question 9First find the value of x by equating the given expressions for TN and TP:
[tex]\implies \sf TN=TP[/tex]
[tex]\implies 4x-17=x+10[/tex]
[tex]\implies 3x=27[/tex]
[tex]\implies x=9[/tex]
Substitute the found value of x into the expression for TN:
[tex]\implies \textsf{TN} = 4(9) - 17[/tex]
[tex]\implies \textsf{TN} = 19[/tex]
As RT is the perpendicular bisector of MN, then ΔTRN is a right triangle where ∠TRN is 90°.
Given:
RN = 14TN = 19To calculate the length of RT, use Pythagoras Theorem:
[tex]\implies \sf RN^2+RT^2=TN^2[/tex]
[tex]\implies \sf RT=\sqrt{TN^2-RN^2}[/tex]
[tex]\implies \sf RT=\sqrt{19^2-14^2}[/tex]
[tex]\implies \sf RT=\sqrt{165}[/tex]

The linear equation that models the population is:
p(t) = 2200*t - 4356000
And in 2010 the population was 66000.
How to find the formula for the population?We know that the population grows linearly.
Remember that the general linear equation can be written as:
y = a*t +b
Where a is the slope and b is the y-intercept.
And if the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Here we have the points (2005, 55000) and (2008, 61600)
Then the slope is:
a = (61600 - 55000)/(2008 - 2005)
a = 2200
Then the line is something like:
y = 2200*t + b
To find the value of b we can replace the values of the point (2005, 55000), then we will get:
55000 = 2200*2005 + b
55000 - 2200*2005 = b
-4356000 = b
The linear equation is
p(t) = 2200*t - 4356000
The population in 2010 is:
p(2010) = 2200*2010 - -4356000 = 66000

Consider the complex number -i√5.
What is the real part?
Answer: The real part of the complex number is 0.
Step-by-step explanation:
Complex numbers are always in the format: a + bi
On the given complex number, -i√5 , it is representing the "bi" part of the standard complex number expression.
We are looking for the real part. The real part is the real number. Since -i√5 doesn't show a real part, we can infer that its real part is 0.
If you rewrite the expression with 0 as the real number, it is equivalent to the principle of the original:
0 + -i√5
This concept is similar to the idea:
y = mx + b
if the equation said:
y = 3x
we know that b is 0, although its not stated. This principle is used in complex numbers.

A circle with a radius of 14 feet is cut into 8 equal pieces. How many square feet are 3 of the pieces? Use 22 over 7 for π.
A. 1,155 square feet
B. 231 square feet
C. 22 square feet
D. 11 square feet
The requried area of 3 of the pieces is 231 square feet. Option B is correct.
What is the area of the circle?The area of a circle is the amount of space enclosed by the circle in a two-dimensional plane. It is given by the formula:
A = πr²
where "A" is the area of the circle, "r" is the radius of the circle, and "π" (pi) is a mathematical constant with an approximate value of 3.14159.
Here,
The area of a full circle with a radius of 14 feet is given by:
A = πr²
A = (22/7) × (14)²
A = (22/7) × 196
A = 616 square feet (rounded to the nearest whole number)
If the circle is cut into 8 equal pieces, each piece will have an area of:
616 ÷ 8 = 77 square feet
Therefore, 3 pieces will have an area of 3 × 77 = 231 square feet.
Thus, the requried area of 3 of the pieces is 231 square feet. Option B is correct.

Mr. Simon purchased 12 tickets (some
student and some adult) for $54. Write
and solve a system of equations to find
out how many adult tickets and how
many student tickets were purchased.
Please show work!
Answer:
adult tickets purchased = 9
student tickets purchased = 3
Step-by-step explanation:
a = # of adult tickets purchased
s = # of student tickets purchased
(1) a + s = 12
(2) $5a + $3s = $54
solve equation (1) for s:
s = 12 - a now substitute this into equation (2) so you have an expression all in terms of a
$5a + $3(12 - a) = $54 solve for a
5a + 36 - 3a = 54
2a = 54 - 36 = 18
a = 18/2 = 9 substitute this into equation (1) and solve for s
9 + s = 12
s = 12 - 9 = 3
A group of 46 people where 7 of them are O blood type. Two persons will be randomly selected in succession to do donate blood. What is the probability that both are O blood type ? Round your answer to 4 decimal places.
Probability that both donators are O blood type = 0.0203
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x.
The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Given,
A group of 46 people where 7 of them are O blood type
Probability of one donator to be O blood type
= No. of People with O blood type/total People in the group
= 7/46
No. of people left in the group left after choosing one donator = 46 - 1 = 45
No. of People left with O Blood type = 7 - 1 = 6
Probability of 2nd donator to be O blood type = 6/45
Probability that both are O blood type = 7/46 × 6/45
= 42/2070
= 0.0203
Hence, there is probability of 0.0203 that both donators are of O blood type.

What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
Rate of inflation = 2%
The cost of pair of shoes = $60
Cost after 5 years = ?
After 1 year cost will be,
⇒ $60 + 2% of original cost
2% of original cost = (60 x 2)/100
= 0.02 x 60
⇒ $60 + $0.02 x 60
⇒ $60(1 + 0.02)
After 2 year cost will be,
⇒ $60(1 + 0.02) + 2% of cost after 1 year
2% of original cost = ( 60(1 + 0.02) x 2)/100

⇒ $60(1 + 0.02) + $0.02 x 60(1 + 0.02)
⇒ $60(1 + 0.02)(1 + 0.02)
Similarly, After 5 years,
⇒ $60(1 + 0.02)(1 + 0.02)(1 + 0.02)(1 + 0.02)(1 + 0.02)
⇒ $ 60 x 1.02⁵
⇒ $ 60 x 1.104
⇒ $ 66.245
Hence, the cost will be $66.245
