The first ten terms of the Fibonacci sequence are 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and so on.

The Fibonacci numbers, sometimes known as Fn in mathematics, are a series of numbers. Each number in the Fibonacci sequence is composed of the sum of the two numbers before it. Typically, the sequence begins with 0 and 1.

means

0 + 1 = 1

1 + 1 = 2

1 + 2 = 3

2 + 3 = 5

3 + 5 = 8

5 + 8 = 13

8 + 13 = 21

13 + 21 = 34

21 + 34 = 55

34 + 55 = 89

Hence,the first ten terms of the Fibonacci sequence are 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and so on.

A series of integers known as the Fibonacci sequence begins with a zero, is followed by a one, another one, and then a series of increasing numbers. Each number in the series equals the sum of the two numbers before it. Every succeeding pair of Fibonacci numbers has a quotient resembling the golden ratio.

Step-by-step explanation:

The geometric mean can be determined by multiplying the terms from part c and the first term of the sequence from part a and taking their square root.

The first term of the sequence from part a is 2 and the term from part c is 512.

Geometric mean of a sequence is the average value of a set of numbers, determined by multiplying the terms together and taking their root.

In general form, the geometric mean for a n number of terms is n√x1*x2*x3*…*xn

Since there are two terms 2 and 512, we will take the square root of the product.

Geometric mean=√2*512=√1024=32

For the geometric sequence as it is the mean, the term will be the 2nd term of the sequence

Hence, the geometric mean of the two chosen positive number 2 and 512 is 32 which is the 2nd term.

Answer:

Step-by-step explanation:

when naming or labeling a line it matters which points you use

The total of a geometric series is an unlimited number of terms with a fixed ratio between them.

If S n= a₁ + a₁r+ a₁ r²+ . . +a₁ rⁿ⁻¹ then rSn = a₁r + a₁ r²+ . . +a₁ rⁿ⁻¹+a₁ rⁿ.

The sum of a geometric series Sn  is given by:

[tex]$S_n=a(\frac{1-r^{n} }{1-r} )[/tex]

Given:

Sum of first n terms of the Geometric progression be

Sn = a₁ + a₁r + a₁ r² + . . + a₁ rⁿ⁻¹  ---(1)

On multiplying by r on both sides,

r Sn = a₁r + a₁ r² + . . + a₁ rⁿ⁻¹ + a₁ rⁿ  ----(2)

So, (2) − (1) gives,

[tex]rS_n-S_n=ar^{n} -a[/tex]

[tex]S_n(r-1)=a(r^{n} -1)[/tex]

Therefore, the sum of n terms of a GP is:

[tex]$S_n=a(\frac{1-r^{n} }{1-r} )[/tex]

Let the expression be r S n = a₁r + a₁ r² + a₁ r³ + . . . . + a₁rⁿ

Sum of first n terms of the Geometric progression is:

Sn = a₁ + a₁r + a₁ r² + . . + a₁ rⁿ⁻¹  

On multiplying by r on both sides, we get

rSn = a₁r + a₁ r²+ . . +a₁ rⁿ⁻¹+a₁ rⁿ  

Therefore, rSn = a₁r + a₁ r²+ . . +a₁ rⁿ⁻¹+a₁ rⁿ

An infinite geometric series is the outcome of an unlimited geometric sequence.

The infinite geometric series be 2/5 +4/25 + 8/125 + . . . . then the sum of the infinite geometric series is 2/3.

An infinite geometric series is the outcome of an unlimited geometric sequence. This series wouldn't have a finish. It is possible to calculate the sum of all finite geometric series. The terms in the sequence will grow steadily larger, but adding the larger numbers together will not provide a solution if the common ratio of an infinite geometric series is greater than one.

Given:

a(first term) = 2/5

r(common difference) = 2/5

Since, |r| < 1 the infinite series converges.

[tex]S_\infty[/tex] = a/1-r ; -1 < r < 1

[tex]S_\infty[/tex] = (2/5)/(1-2/5)

simplifying the above equation, we get

The equation of the line parallel and perpendicular are y = -0.9(x+7) and y = 10/9(x+7) respectively

The equation of a line in point slope form is expressed as;

y - y₁ =m(x-x₁) (Parallel)

y - y₁ =-1/m(x-x₁)  (Perpendicular)

Given the following

Point = (-7, 0)

Slope = -0.9

Substitute

y -0 = -0.9(x-(-7))

y = -0.9(x+7)

Similarly for the perpendicular line

y -0 = -1/-0.9(x-(-7))

y = 10/9(x+7)

Considering the expression of a line and how to obtain it having 2 points, you obtain:

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x1, y1) and (x2, y2) of a line, the slope m of said line can be calculated using the following expression:

m= (y2 - y1)÷ (x2 - x1)

Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.

In this case, you want to obtaina linear equation giving the sales y in terms of the year x. You know:

So, being (x1,y1)= (2011, 32.266) and (x2,y2)= (2012, 33.278), the slope m can be calculated as:

m= (33.278 - 32.266)÷ (2012 - 2011)

Solving:

m=1.012

Considering point 1 and the slope m, you obtain:

32.266= 1.012×2011 + b

32.266= 2035.132 + b

32.266- 2035.132= b

- 2002.866= b

Finally, the linear equation giving the sales y in terms of the year x is y=1.012x - 2002.866

You can use the equation to predict the sales for 2013 as follow:

y=1.012×2013 - 2002.866

Solving:

y=1.012×2013 - 2002.866

y= $34.29 billion

Finally, the sales in 2013 will be $34.29 billion.

The equation in the form ax+ by=c a>0 where a and b are not both zero and a, b, and c are integers with greatest common actor  of 1 represent either linear or non linear function. Hence, this statement is true.

The formula for a linear function is f(x) = mx + b, where m and b are real values. Isn't it resembling the slope-intercept form of a line, represented by the equation y = mx + b? Yes, this is the case as the graph of a linear function is a line.

Here,

• 'm' is the slope of the line.

• 'b' is the y-intercept of  line.

• 'x' is the independent variable.

• 'y'  is the dependent variable.

As the name suggests, a nonlinear function is one that is NOT linear. To put it another way, a nonlinear function's graph is not a line, which means that its graph can be anything other than a line.

Given that, ax+ by=c a>0 where a and b are not both zero and a, b, and c are integers with a greatest common factor of 1

ax+ by -c=0     [by transpose]

The general form of linear equation is ax+ by +c z +d=0

So, it is a binary first order equation of 'x' and 'y'.

By looking at the graph:

Domain: (-6, 1] U (1, 5]

Range:  (-3, 2] U [3, 7)

The domain is the set of inputs (horizontal axis) and the range is the set of the outputs (vertical axis).

By looking at the horizontal axis we can see that the first part goes from x = -6 to x = -1, this interval is (-6, 1]

(at x = -6 there is a open circle, so x = -6 does not belong to the domain)

Similarly, the second interval is (1, 5]

Then the domain is D: (-6, 1] U (1, 5]

Step-by-step explanation:

The distance between the pair of points X(-2,5) and Y(1,11) is [tex]\sqrt{45}[/tex] units.

We can find the distance between the points X and Y by using distance formula.

The distance formula is used to find the distance between two defined points on a graph (in the absence of a scale).

Here the two points are  X(-2,5) and Y(1,11).

The distance formula for points (a,b) and (c,d) is given by :-[tex]\sqrt{(d-b)^2+(c-a)^2}[/tex]

Here,

(a,b) represents the point X(-2,5), and

(c,d) represents the point Y(1,11)

Putting the values of (a,b) and (c,d) in the distance formula, we get,

[tex]\sqrt{(11-5)^2+(1-(-2))^2}[/tex]
