The first six terms of the sequence are 2, 1, 3, 4, 7, and 11.

The 12th term is 199.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(1) = 2

f(2) = 1

f(n) = f(n - 1) + f(n - 2)

Now,

For n = 3,

f(3) = f(3 - 1) + f(3 - 2) = f(2) + f(1) = 1 + 2 = 3

f(4) = f(4 - 1) + f(4 - 2) = f(3) + f(2) = 3 + 1 = 4

f(5) = f(5 - 1) + f(5 - 2) = f(4) + f(3) = 4 + 3 = 7

We see that,

The next sequence is the addition of the previous two sequences.

So,

The sequence is:

2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199

i.e

12th term = 199.

Thus,

First six terms of the sequence =  2, 1, 3, 4, 7, 11

Answer: The first term of the sequence is 2, and the second is 1. The function adds the previous two terms to get the next term.

To get the first six terms of the sequence, start by finding the third term by substituting the values of the first two terms in the function:

f(3) = f(2) + f(1) = 1 + 2 = 3.

In the same way, find the remaining three terms and get the sequence as (2, 1, 3, 4, 7, 11, . . .).

To find the 12th term of the sequence, continue using the rule to find all terms until the 12th. So, the sequence is (2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, . . .).

The approximate area between the x-axis and the function, f(x) = x² + 3, obtained by finding the sum of the of the four rectangles is Area ≈ 9.75

The area between the x-axis and the graph under a function can be referred to as the area under a curve of the function, which can be found using definite integrals.

The area between the x-axis and the function f(x) = x² + 3 over the interval [0, 2], can be found by finding the area of the rectangular bars, A, in the figure as follows;

The values at the endpoints of the rectangles are; 0.5, 1, 1.5, and 2

Therefore;

f(0.5) = 0.5² + 3 = 3.25

f(1) = 1² + 3 = 4

f(1.5) = 1.5² + 3 = 5.25

f(2) = 2² + 3 = 7

Therefore; A = 0.5 × f(0.5) + 0.5 × f(1) + 0.5 × f(1.5) + 0.5 × f(2)

Plugging in the values of the function, we get;

Area ≈ 0.5 × 3.25 + 0.5 × 4 + 0.5  × 5.25 + 0.5 × 7 = 9.75

What is perimeter?

The complete length of a shape's edge serves as its perimeter in geometric terms. Adding the lengths of all the sides and edges that surround a form yields its perimeter. It is calculated using linear length units such centimeters, meters, inches, and feet.

There are 2 shapes: half circle and right triangle

diameter of half circle ,d=10

radius, r=d/2 = 10/2 = 5

Perimeter of half circle = π r = 3.14 * 5 = 15.7

In the right triangle,

base = 5, line perpendicular to  base = 10

hypotenuse² = squares of  other 2 sides  added

                       = 5² + 10²

                       = 25 +100

                       = 125

hypotenuse = ± √125 = ±11.18

Answer: 18:21

Answer:

  the required equation is x² -10x +18 = 0

Step-by-step explanation:

Given side x and diagonal 8 cm of a rectangle with perimeter 20 cm, you want to show that the value of x satisfies an equation of the form ...

  x² +ax +b = 0 . . . . . where a and b are integers.

The perimeter is the sum of the side lengths. It can be expressed by the formula ...

  P = 2(L +W)

Solving for W gives ...

  W = P/2 -L

For the given rectangle, the width is ...

  W = 20/2 -x = 10 -x

The length of the diagonal is related to the length and width of the rectangle by the Pythagorean theorem.

  c² = a² +b²

  8² = x² +(10 -x)² = 2x² -20x +100

  32 = x² -10x +50 . . . . . . . . divide by 2

  x² -10x +18 = 0 . . . . . . . . . . subtract 32

This shows that x must satisfy a quadratic of the form x² +ax +b = 0, where a=-10, and b=18, both integers.

The solution set of the given homogeneous system in parametric vector form is x₁ = 5 = x₂ , x₃ = 1.

What is parametric vector form?

The identity matrix's two columns, which stand in for the two leading coefficients in the row echelon form of the original matrix, are added to create the parametric vector.

We are given set of equations as:

x₁ + 2x₂ - 15x₃ = 0

2x₁ + x₂ - 15x₃ = 0

-x₁ + x₂ = 0

Now, representing this in the matrix form, we get

[tex]\left[\begin{array}{cccc}1&2&-15&0\\2&1&-15&0\\-1&1&0&0\end{array}\right][/tex]

Now, we will reduce the matrix i.e. in row echelon form using elementary operations

From this, we get

[tex]\left[\begin{array}{cccc}1&0&-5&0\\0&1&-5&0\\0&0&0&0\end{array}\right][/tex]

So, we get that x₃ is the free variable.

Now, representing this in the parametric vector form, we get

x₁ - 5x₃ = 0

x₂ - 5x₃ = 0

x₃ = x₃

From this, we get

x₁ = 5x₃

x₂ = 5x₃

x₃ = x₃

So, we now get

x = [tex]\left[\begin{array}{c}x_{1} &x_{2} &x_{3} \end{array}\right][/tex]

This is equal to

x = [tex]\left[\begin{array}{c}5x_{3} &5x_{3} &x_{3} \end{array}\right][/tex]

Thus,

Answer: 6x=90

Step-by-step explanation:

We know that one angle in a right triangle is 90 degrees and the sum of all the angles is 180, so we can start by subtracting 90 from 180. We are left with 90 and now we have angle ratios which represent fractional quantities. We know that one of these quantities is 5 and the other is 1. Their sum is 6 and equals 90. So the proportion would be 6x = 90. The larger angle is 75 degrees and the smaller one is 15.

For the statement "Integer x divisible by 6" the option C is correct.

Either statements are NOT sufficient, but BOTH together are sufficient.

What is integer?

The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

(1) x + 3 is divisible by 3

This means that x is a multiple of 3.

Hence x + 3 is a multiple of 3.

But x could be 0, 3, 6. If x = 3, x is not divisible by 6.

Otherwise it is.

So, this statement is insufficient.

(2) x + 3 is an odd number

This means that x is an even number.

X can be 6, or 10.

So, this statement is insufficient.

Together -

From (1) it is known that x is a multiple of 3.

Hence X can be 0,3,6,9,12,15,18,21,24,27,30.

From (2) it is known that x is even.

Hence X can be 0,6,12,18,24,30.

Range = 7. IQR = 4.5. Variance: 8.67, Std Dev: 2.96 when researcher organized diet groups on weight loss weighed five clients after several weeks on the program.

The range of the weight-loss scores can be calculated by subtracting the smallest value from the largest value. In this case, the range would be

13 - 6 = 7.

The inter-quartile range (IQR) is calculated as the difference between the 75th percentile and the 25th percentile of the data.

IQR: 11.25 - 6.75 = 4.5

To calculate the variance, first find the mean weight-loss score by summing all the scores and dividing by the number of clients: (13 + 12 + 6 + 9 + 9 + 10) / 6 = 9.17. Next, subtract the mean from each score and square the result for each client:

[tex](13 - 9.17)^2 = 3.69\\(12 - 9.17)^2 = 1.69\\(6 - 9.17)^2 = 16.0\\(9 - 9.17)^2 = 0.02\\(9 - 9.17)^2 = 0.02\\(10 - 9.17)^2 = 0.69[/tex]

Next, sum the squared deviations and divide by the number of clients minus one (n-1):

(3.69 + 1.69 + 16.0 + 0.02 + 0.02 + 0.69) / (6-1) = 4.83
