If you put the function on a graphing calculator you can see how they work

may I get brainliest thanks

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 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

The APR would therefore be :

= ( 1, 452. 70 - 500 ) / 500

Answer:

Step-by-step explanation:

From the given information provided, she has 14.50 dollars money left to spend on gift C.

To find out how much money is left for gift C, we first need to add up the amounts spent on gift A and gift B:

8 9/10 dollars + 6 3/5 dollars = (8 + 6) + (9/10 + 3/5) dollars

= 14 + (9/10 + 6/10) dollars

= 14 + 15/10 dollars

= 15 5/10 dollars

= 15.50 dollars

So the total amount spent on gift A and gift B is 15.50 dollars. To find out how much money is left for gift C, we need to subtract this amount from the total amount she has to spend:

30 dollars - 15.50 dollars = 14.50 dollars

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:

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.

Therefore, the expression is only true for a = 5.

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

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.
