The main function is given by:

f (x) = sine (x)

We then have the following transformations:

Reflections:

Reflection or turning is the mirror image of a figure. It can also be said that it is the turning of points and graphs around the axes.

To graph y = -f (x), reflect the graph of y = f (x) on the x-axis. (Vertical reflection)

f (x) = - sine (x)

Expansions and vertical compressions:

To graph y = a*f (x)

If a> 1, the graph of y = f (x) is expanded vertically by a factor a.

f (x) = - 2 * sine (x)

Vertical translations

Suppose that k> 0

To graph y = f (x) + k, move the graph of k units up.

f (x) = - 2 * sine (x) + 3

Answer:

C. reflection across the x-axis, vertical stretching by a factor of 2, vertical translation 3 units up

The set of transformations which is needed to graph f(x) = –2sin(x) + 3 is reflection across the x-axis, vertical stretching by a factor of 2, vertical translation 3 units up, the correct option is C.

A rigid transformation (also called an isometry) is a transformation of the plane that preserves length. In a rigid transformation the pre-image and image are congruent (have the same shape and sizes).

We are given that;

The function= f(x) = –2sin(x) + 3

Now,

To graph f(x) = –2sin(x) + 3 from the parent sine function y = sin(x), we need to apply the following transformations:

A reflection across the x-axis, because of the negative sign in front of the 2.

A vertical stretching by a factor of 2, because of the absolute value of the coefficient of sin(x), which is 2.

A vertical translation 3 units up, because of the constant term 3.

Therefore, by transformations answer will be Reflection across the x-axis, vertical stretching by a factor of 2, vertical translation 3 units up.

The possible lengths to complete a triangle with side lengths of 9 in. and 11 in. are greater than 2 in. and less than 20 in., which is correctly represented by options B.

How to determine the length of the triangle ?

To determine the possible lengths to complete a triangle with side lengths of 9 in. and 11 in., we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Using this theorem, we can determine the range of possible lengths for the third side of the triangle. We start by adding the two given side lengths:

9 + 11 = 20

The third side must be less than the sum of the other two sides, so the third side must be less than 20 in.

Next, we subtract the two given side lengths:

11 - 9 = 2

The third side must be greater than the difference of the other two sides, so the third side must be greater than 2 in.

Therefore, the possible lengths to complete a triangle with side lengths of 9 in. and 11 in. are between 2 in. and 20 in. This eliminates options A and C from the choices given.

Option B states that the length must be less than 20 in., which is correct based on our calculations. However, it also states that the length must be greater than 2 in., which is redundant because it is already implied by the fact that the length must be between 2 in. and 20 in. Therefore, option B is also correct.

Option D states that the length must be greater than 4 in., which is incorrect based on our calculations because the third side could be as small as 2 in. Therefore, option D is not correct.

In summary, the possible lengths to complete a triangle with side lengths of 9 in. and 11 in. are greater than 2 in. and less than 20 in., which is correctly represented by options B.

Answer:

(√122 - √10)/112.

Step-by-step explanation:

The average rate of change of a function f(x) over an interval [a, b] is given by:

average rate of change = (f(b) - f(a))/(b - a)

Here, we have f(x) = √x - 1, a = 10, and b = 122. So, the average rate of change of f(x) from x = 10 to x = 122 is:

(f(122) - f(10))/(122 - 10)

= (√122 - 1 - √10 + 1)/(112)

= (√122 - √10)/112

Therefore, the exact, fully simplified answer for the average rate of change of f(x) from x = 10 to x = 122 is (√122 - √10)/112.

The ninth term of the given geometric sequence is 8/2187.

Now, let's apply this concept to solve the problem. We are given two terms of a geometric sequence: a₂ = -24 and a₅ = 8/9. We need to find a₉.

First, let's find the common ratio (r) of the sequence. To do this, we can use the formula for the nth term of a geometric sequence:

an = a1 x rⁿ⁻¹

We can use this formula for two different terms of the sequence to find the common ratio. Let's use a₂ and a₅:

a₂ = a₁ x r²⁻¹ --> -24 = a₁ x r

a₅ = a₁ x r⁵⁻¹ --> 8/9 = a₁ x r⁴

Now, let's divide these two equations to eliminate a1:

(-24) / (8/9) = r / r⁴

Simplifying, we get:

-27 = 1/r³

Taking the cube root of both sides, we get:

r = -1/3

Now that we know the common ratio, we can use the formula for the nth term of a geometric sequence to find a₉:

a₉ = a₁ x r⁹⁻¹

We don't know a1, but we can use the fact that a₂ = -24 to find it:

a₂ = a₁ x r²⁻¹ --> -24 = a₁ x (-1/3)

Simplifying, we get:

a₁ = 72

Now we can substitute the values we found for a1 and r into the formula for a₉:

a₉ = a₁ x r⁹⁻¹ --> a₉ = 72 x (-1/3)⁸

Simplifying, we get:

a9 = 8/2187

For any real number x, x > 5 implies that x ≥ 5 is the true statement.

For any real number x, x > 5 implies that x ≥ 5 is the true statement. This can be expressed with the following inequality:

x > 5 implies x ≥ 5

This means that if x is greater than 5, then x must be greater than or equal to 5. We can demonstrate this with an example calculation. Let x = 6.

6 > 5

We can see that 6 is greater than 5, so the inequality is true.

6 ≥ 5

We can see that 6 is also greater than or equal to 5, so the inequality is also true. Therefore, for any real number x, x > 5 implies that x ≥ 5.

Answer:

Step-by-step explanation:

The square root of 2, or any other irrational number, will produce an irrational answer when added to 7/8.

Ancient mathematicians understood that a square with one-unit-long sides has a diagonal whose length is irrational. The Pythagorean Theorem states that the length of the diagonal is equal to the square root of two. Thus, it is absurd to use the square root of 2!

When added to 7/8, the square root of 2 or any other irrational number will result in an absurd result.

This is so that irrational numbers can be expanded indefinitely without repeating, since they cannot be stated as a fraction of two integers.

The consequence of adding an irrational number to a rational one, such as 7/8, will also be irrational since the irrational number cannot be reduced to a fraction of two integers because its decimal expansion will go on indefinitely without repeating.

we know that we must add 29.8% more, in decimal form, to the net income in order to get the gross income.

Let's see the facts:

Income = $3,788

Withheld:

6.2% for social security

1.45% for medicare

16% for federal income tax

6.15% for state income tax

Now, with this given data, we can asseverate that the gross income is obtained by multiplying the net income by the sum of percentages as follows:

The sum of contributions: 6.2+1.45+16+6.15 = 29.8 %

So, we know that we must add 29.8% more,in decimal form, to the net income in order to get the gross income.

The gross income is:

Gross income= 3,788x 1.298

The expression is only true for a = 5.

An expression is a combination of numbers, variables, and operations that represents a quantity or a mathematical relationship. It can be a simple or complex representation of a value or function, and it can be evaluated or simplified using algebraic or numerical methods.

The given expression is:

(1/2)a - 5 (1/2) = (5 - a)

To find the values of 'a' that make this expression true, we can simplify and solve the equation:

(1/2)a - 2.5 = 5 - a

Adding 'a' to both sides:

(3/2)a - 2.5 = 5

Adding 2.5 to both sides:

(3/2)a = 7.5

Multiplying both sides by 2/3:

a = 5

Therefore, the expression is true when a = 5.

To verify, we can substitute a = 5 into the original expression:

(1/2)(5) - 5 (1/2) = (5 - 5)

2.5 - 2.5 = 0

The expression evaluates to 0, which is true.

The APR on the loan, given the amount you are to pay in interest every day, can be found to be 190. 54 %

To calculate the APR (Annual Percentage Rate) for this loan, we need to know the total interest paid over the course of a year, as a percentage of the loan amount.

First, we need to determine the total interest paid over the course of one year. Since the interest rate is $3.98 per day, we can multiply that by the number of days in a year (365) to get the total interest paid per year:

$3.98 x 365 = $1, 452.70
