The 25th term in the sequence 11, 20, 29, 38, 47… is 227.

Based on the information illustrated, it should be noted that the 25th term in the sequence 11, 20, 29, 38, 47… will be calculated thus:

In this case, this is an arithmetic sequence. The formula to calculate the sequence will be:

= a + (n - 1)d

a = first term = 11

d = common difference = 9

The 25th term will be:

a + (n - 1)d

= 11 + (25 - 1)9

= 11 + (24 × 9)

= 11 + 216

= 227

The 25th term is 227.

The indefinite integral, [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{-1}{9} cos(9x) + C[/tex]

We have to find the indefinite integral,

    [tex]\int {sin(9x)} \, dx[/tex]

using the substitution 9x = u.

So we need to change the variable of integration from x to u using this substitution.

9x = u ⇒ 9 dx = du

So   [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{1}{9} \int{sin(u) \ du[/tex]

                          = 1/9 (- cos(u)) + C,   [ Since integral of sin(u) = -cos(u) ]

where C is the integration constant which is often put when evaluating indefinite integrals.

Now replacing u with x to get the final answer,

1/9 (- cos(u)) + C = -1/9 cos(9x) + C

Therefore,   [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{-1}{9} cos(9x) + C[/tex]

The question is incomplete. Find the complete question below:

Evaluate the indefinite integral by using the given substitution to reduce the integral to standard form.   [tex]\int {sin(9x)} \, dx[/tex], 9x = u.

What is a fraction?

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction consists of a numerator, displayed above a line, and a non-zero denominator, displayed below that line. Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals.

The first five terms of a sequence with explicit formula a(n) = 2n - 1 are 1,3,5,7,9  (G)

An arrangement of numbers with particular pattern is called a sequence. In general, there are four types of sequence: arithmetic sequence, geometric sequence, quadratic sequence, and special sequence.  

Suppose we are given an explicit formula for the nth term of a sequence, then its terms can be evaluated by substituting n = 1, 2, ...

The explicit formula of the given sequence:

a(n) = 2n - 1

Take n = 1, then

a(1) = 2.(1) - 1 = 1

Take n = 2, then

a(2) = 2.(2) - 1 = 3

Take n = 3, then

a(3) = 2.(3) - 1 = 5

Take n = 4, then

a(4) = 2.(4) - 1 = 7

Take n = 5, then

a(1) = 2.(5) - 1 = 9

Hence, the first five terms are 1,3,5,7,9  (G)

The probability, expressed as a percentage rounded to a nearest tenth, that Victoro chooses a green jelly then a red one is 0.1.

A combination is a preference of all or part of a group of objects, regardless of their order of selection.

You can choose the items in just about any order in combinations. Permutations and combinations are often confused.

Now, as per the given question;

The total number of red jelly beans in a bag is 7.

The total number of yellow jelly beans in a bag is 11.

The total number of green jelly beans in a bag is 13.

Thus, the total number of jelly beans in a bag is;

7 + 11 + 13 = 31.

First, Victoro picks the green one;

Thus, the probability of picking a green jelly out of total 13 green jellys is;

¹³C₁/ ³¹C₁ = 13/31

Now, as the second jelly picked by Victoro is red which is without replacement.

Thus, the probability for getting a red jelly out of total 30 left jellys is;

⁷C₁/ ³⁰C₁ = 7/30

Therefore, the total probability that Victoro picks a green one and then a red one is ;

= 13/31×7/30

= 91/930

= 0.097

= 0.10 (rounded to the nearest tenth)

Therefore, the probability of getting the red jelly after the green jelly is 0.10.

For the value of (b = -5) the result of the solution is x ≤ - 6.

The term inequality refers to a mathematical equation wherein the sides are not equal. An inequality equates any two values and shows that one is less, greater, or equal to the value on either side of the equation.

Consider the given expression;

38 ≤ bx + 8

Simplify the equation;

38 - 8 ≤ bx

30 ≤ bx

Multiply both side with negative sign; by the rule four, the sign of inequality will also change.

- 30 ≥ -bx

or  -bx ≤ - 30

For converting the value to the expression x ≤ - 6; the value which should be divide the 30 is 5.

Thus,

-(-5)x  ≤ - 30

Thus, the value of b is found as (b = -5).

Using it's concept, the average rate of change of the function in the intervals is given by:

a. 1.

b. -5/3.

c. -1.

d. 4.

e. -3.

f. 0.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For item a, we have that:

Hence the rate is:

r = (1 - 0)/(-2 - (-3)) = 1.

For item b, we have that:

Hence the rate is:

r = (-4 - 1)/(1 - (-2)) = -5/3.

For item c, we have that:

Hence the rate is:

r = (-4 - (-3))/(1 - 0) = -1.

For item d, we have that:

Hence the rate is:

r = (-0 - (-4))/(2 - 1) = 4.

For item e, we have that:

Hence the rate is:

r = (-3 - 0)/(0 - (-1)) = -3.

For item f, we have that:

Hence the rate is:

r = (0 - 0)/(2 - (-1)) = 0.

The base and height of parallelogram is 6 meters and 18 meters.

We are given the relationship between base and height of parallelogram. Let the height be h and base be b. The equation is as follows -

h = 3×b

The formula to calculate area of parallelogram is -

Area = base × height

Keep the values in formula to find the base of parallelogram -

108 = b×3×b

Performing multiplication on Right Hand Side of equation

108 = 3b²

b² = 108÷3

Performing division to find the base of parallelogram -

b² = 36

b = √36

Taking square root of b

b = 6 meters

So, the base of parallelogram is 6 meters.

Height = 3 × 6
