Hello, Please consider the following.
Fibonacci numbers are defined as
[tex]u_0=1\\\\u_1=1\\\\u_{n+2}=u_{n+1}+u_{n} \ for \ n\geq 0[/tex]
Step 1 - The proposition is true for n = 1
[tex]GCD(u_2,u_1) ?\\[/tex]
Let's apply Euclidean algorithm
[tex]u_1=1, u_2=2\\\\u_2=2\times u_1+0 = 2 \times 1 +0[/tex]
This is exactly 1 step and [tex]GCD(u_2,u_1) =1[/tex]
Step 2 - We assume that this is true for k, meaning that the Euclidean algorithm takes precisely k steps to prove that [tex]GCD(u_{k+1},u_{k})=1[/tex]
[tex]u_{k+2}=u_{k+1}+u_k \ and \ 0 < u_k < u_{k+1}[/tex]
So, the first step of the algorithm is
[tex]u_{k+2}=u_{k+1}\times 1 +u_{k}[/tex]
And from now, we need to find [tex]GCD(u_{k+1},u_k)[/tex] which is 1 and takes k steps, by induction Hypothesis. Therefore, it takes k + 1 steps to find [tex]GCD(u_{k+2},u_{k+1})=1[/tex]
Step 3 - Conclusion
We have just proved that the Euclidean algorithm takes precisely n steps to prove that [tex]GCD(u_{n+1},u_{n})=1[/tex]

This histogram shows the percentage of the population that smokes tobacco for 123 countries. Which one of the following values is the most reasonable estimate for the IQR?
Answer:
9.5
Step-by-step explanation:
The formula for interquartile range = Third Quartile - 1st Quartile
= Q3 - Q1
Looking at the histogram given, the class width = 6
Step 1
We find the number of values = n
n = 1 + 12 + 26 + 27 + 31 + 19 + 6 + 1
= 123
Frequency Cumulative Frequency
1 1
12 13
26 39
27 66
31 97
19 116
6 122
1 123
Step 2
We find Q1 ( First Quartile)
Q1 =1/4 (n + 1) value
Q1 = 1/4(124) value
= 31st value
The first Quartile = 31st value
31 - 13 = 18
31st value = 12 + (18/26 × class width)
= 12 +( 18/26 × 6)
First Quartile = 16.153846154
Third Quartile =Q3 =3/4 (n + 1) value
Q1 = 3/4(124) value
= 93rd value
The first Quartile = 93rd value
93 - 66 = 27
93rd value = 1 + (27/97 × class width)
=24 +( 27/97 × 6)
Third Quartile= 25.670103093
Interquartile range = Q3 - Q1
= 25.670103093 - 16.153846154
= 9.5162569392
Approximately = 9.5
Inter Quartile range = 9.5

Find the least common multiple of 5 and 2.
That would be 10.
That means we have to multiply the first fraction by 2/2 and the second one by 5/5
-3/5*2/2
Multiply the numerators together and the denominators together.
-6/10
Repeat with the second fraction.
-8/2*5/5
-40/10
Our new expression is
-6/10+-40/10
-46/10
Simplify
-23/5
As a mixed number that would be:
-4 3/5

Given complex number is (-3 + 2i )
Comparing this number with (a + ib), real part of the number will be (-3) and imaginary part of the number will be 2.
Option (3) will be the answer.
write the equation of a line in any form that is parallel 2y = 4x + 8 through the point of (1,3) plz and thank you
Answer:
y = 2x+1
Step-by-step explanation:
[tex]2y =4x+8\\\\ Write \:in \: y =mx+b \:form\\\\\frac{2y}{2} = \frac{4x}{2} +\frac{8}{2} \\\\y =2x +4\\m =2\\(1,3) =(x_1,y_1)\\Substitute\:values\:into\:point-slope\:form\\\\y-y_1=m(x-x_1)\\y-3=2(x-1)\\y-3 = 2x-2\\y=2x-2+3\\y =2x+1[/tex]
Step-by-step explanation:
Hey, there!!
Here, the given point is (1,3).
Now, Using one point formula we need to find the equation of the line passing through point (1,3).
Now,
[tex](y - y1) = m1(x - x1)[/tex]
Keeping values,
[tex](y - 3) = m1(x - 1)[/tex]
It is the 1st equation.
Similary, you have another equation,
2y = 4x + 8..............2nd equation.
or, 4x - 2y +8 =0
M2 from equation 2,
[tex] = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex] = \frac{ - 4}{ - 2} [/tex]
Therefore, m2 = 2
Now,
As per the condition of parallel lines,
m1 = m2 = 2
Now, substituting the value of m1 in equation 1st.
(y-3) = 2 (x-1)
y-3 = 2x - 2
or, 2x-y+1 = 0 ......is the required equation.
Hope it helps...

Find an equation of the line passing through the point (−6,−5) that is parallel to the line y=4/3x−5
Answer:
y = [tex]\frac{4}{3}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{4}{3}[/tex] x - 5 ← is in slope- intercept form
with slope m = [tex]\frac{4}{3}[/tex]
Parallel lines have equal slopes, thus
y = [tex]\frac{4}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 6, - 5) into the partial equation
- 5 = - 8 + c ⇒ c = - 5 + 8 = 3
y = [tex]\frac{4}{3}[/tex] x + 3 ← equation of parallel line

How many inches are in 14 feet, 8 inches? Enter only the number. Do not include units
Answer:
176
Step-by-step explanation:
14x12 = 168 + 8 = 176
There are 176 inches in 14 feet, 8 inches.
To find the total number of inches in 14 feet, 8 inches, we need to convert the feet to inches and then add the inches.
So, 14 feet = 14 x 12
= 168 inches.
Adding the extra 8 inches, the total is:
= 168 inches + 8 inches
= 176 inches.
Therefore, there are 176 inches in 14 feet, 8 inches.

A sector of a circle of radius has an area of . Find the central angle of the sector. Do not round any intermediate computations. Round your answer to the nearest tenth
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, But I would show how to solve the problem
The area of a sector of a circle with radius r and a subtended central angle θ in degree has an area of:
Area = [tex]\frac{\theta}{360}*\pi r^2[/tex]
Where θ is in degrees.
If the central angle is in radian, then the area of the sector is given as:
[tex]Area=\frac{\theta}{2\pi}*\pi r^2\\ Area=\frac{\theta}{2}* r^2[/tex]
Let us assume A circle has a radius of 2.5 mm a sector of the circle has a central angle of 4 pi/3 radians.
Therefore the radius (r) = 2.5 mm and the central angle (θ) = 4π/3
Therefore:
[tex]Area=\frac{\theta}{2}*r^2\\ \\Area=\frac{\frac{4\pi}{3} }{2} *2.5^2=13.1\ mm^2\\[/tex]
