Write the equation for the parent linear value function, f(x)=x, that has been transformed by:
1. reflecting across the x-axis, vertical stretch by a scale factor 4, and a translation of 4 units up and 5 units left
2. vertical shrink by a scale factor of 1/4 and a horizontal shift 10 units right.
3. reflection in the x-axis, a vertical shift of 4 units up and a horizontal shift 7 units left
The required functions after transformations are y = -4(x+4)+5, y = (x-o)/14, y = -x+4
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given that, the equation for the parent linear value function, f(x)=x, that has been transformed by,
a) Reflecting across the -axis, vertical stretch by a scale factor 4, and a translation of 4 units up and 5 units left :-
Rule for reflection across x-axis = y = f(x) → y = -f(x)
After reflection,
f(x) = -x
And there is a vertical stretch by a scale factor 4, and a translation of 4 units up and 5 units left
f(x) = -4(x+4)+5
Therefore, the function will be f(x) = -4(x+4)+5
b) Vertical shrink by a scale factor of 14 and a horizontal shift O units right.
For vertical shrink = f(x)/14 = x/14
For horizontal shift = (x-o)/14
Therefore, the function will be f(x) = (x-o)/14
c) Reflection in the x-axis, a vertical shift of 4 units up and a horizontal shift 7 units left.
Rule for reflection across x-axis = y = f(x) → y = -f(x)
f(x) = -x
For a vertical shift of 4 units up and a horizontal shift 7 units left =
f(x) = (-x-7)+4
Hence, The required functions after transformations are y = -4(x+4)+5, y = (x-o)/14, y = -x+4

what is the difference between the maximum and minimum values of f ?
f(x) = cos (2x) + cos x
how do i find the max and min of such?
The maximum value of the function f ( x ) = 2
The minimum value of function f ( x ) = - ( 9/8 )
The difference between the maximum and minimum values of f ( x ) = 25/8
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as f ( x )
The value of f ( x ) = cos (2x) + cos x be equation (1)
On simplifying the equation , we get
To maximize f ( x ) = cos ( 2x ) + cos x , differentiate it with respect to x
So ,
f' ( x ) = -2 sins ( 2x ) - sinx
And , For the function to achieve a minimum value , f′(x) should be 0
So , Substituting the values in the equation , we get
-2 sins ( 2x ) - sinx = 0
Adding sinx on both sides of the equation , we get
-2 sins ( 2x ) = sin x
-2 ( 2 sin x cos x ) = sin x
Divide by -4 on both sides of the equation , we get
sin x cos x = sin x / 4
Divide by sin x on both sides of the equation , we get
cos x = ( -1/4 )
Hence minimum value is f ( x ) = 2 x ( 1/16 ) - ( 1/4 ) - 1
The minimum value of f ( x )= - 9/8
And , the function is maximum at cosx = 1
So , f ( x ) = 2 x 1 - 1 + 1 = 2
The maximum value of f ( x )= 2
So , the difference between the maximum and minimum values of f ( x ) =
Maximum value - Minimum value = ( 2 - ( -9 / 8 ) )
Maximum value - Minimum value = ( 16 + 9 ) / 8
Maximum value - Minimum value = 25/8
Hence , the difference between the maximum and minimum values of function f ( x ) is = 25/8

name two numbers that are 5 units from 3 on the number line are represented by equation | n - 3| = 5. What are these two numbers?
Note that the two numbers given the equation |n-3| = 5 which are 5 units from 3 on the number line are: -2 and 8.
What is the rationale for the above answer?A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in elementary mathematics. Every number line point is assumed to correspond to a real number and every real number to a number line point.
One more quality of number lines that is worth noting is that it stretched to the positive infinity and to the negative infinity with zero as the center point.
Given that we have been given the reference point of 3, this means that both numbers must extend one to the positive infinity constrainted by 5 units and one to the negative infinity constrained by 5 units.
Hence,
To find the two numbers that are 5 units away from 3, we can set up two equations:
n - 3 = 5 and n - 3 = -5
Solving for n in the first equation: n = 8
Solving for n in the second equation: n = -2
Therefore, the two numbers that are 5 units away from 3 on the number line are -2 and 8.

pattern of association
In mathematics, the pattern of association refers to the type of correlation that is found between two variables which includes positive, negative, or no correlation.
What is the pattern of association ?The connection between two or more variables is referred to as a pattern of association. There are various variations of this relationship, including a positive correlation, a negative correlation, and no correlation. When both variables rise or fall at the same time, there is a positive correlation. In other words, as one variable rises, the other one rises as well, and vice versa.
When two variables move in the opposing directions, there is a negative correlation. The other variable reduces as one grows, and vice versa. When there is no correlation between the variables, a no correlation exists. This indicates that there is no pattern in the data and that the variables do not change simultaneously.

rewrite the expression as a single logarithm and simplify the result. ln|sin x| + ln|cot x|
The expression can be rewritten as a single logarithm as:
ln|sin x| + ln|cot x| = ln(|sin x||cot x|) = ln|cos x|
This is possible because logarithm function is a monotonically increasing function, meaning that if a > b then log(a) > log(b) and log(a*b) = log(a) + log(b) that's why we can add the two logarithms.
The result is simplified by combining the absolute values of the sin and cot functions into a single term. The absolute value is removed since the product of two positive numbers is always positive. The final result is ln|cos x|, which is the natural logarithm of the product of the sine and cotangent of x.
It is important to note that the cotangent function is defined as 1/tan(x) so that cot(x) = 1/tan(x) and cot(x) is only defined for x where sin(x) is not equal to 0.

Shin splints are a common cause of lower leg pain and can be caused by a variety of factors, such as poorly fitting shoes, weak calf muscles, running on uneven terrain, and overpronation of the foot.
Shin splints is a term used to describe pain that occurs along the shin bone (tibia), which runs down the front of the lower leg. Common causes of shin splints include poorly fitting shoes, weak calf muscles, running on uneven terrain, and overpronation of the foot. Poorly fitting shoes can put excessive pressure on the back of the heel and the front of the foot, leading to inflammation and pain in the shin area. Weak calf muscles can cause the foot to overpronate or roll inward, which can put extra strain on the shin bone and its muscles. Running on uneven terrain can also cause the shin bone to suffer from too much pressure, leading to shin splints. Finally, overpronation of the foot is when the foot rolls inward excessively and puts extra strain on the shin bone and its muscles. Shin splints can cause pain and discomfort and should be treated as soon as possible by rest, stretching, icing, and wearing properly fitting shoes.

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges 1503 to rent trucks plus an additional fee of 125.25 for each ton of sugar. The second company does not charge to rent trucks but charges 250.50 for each ton of sugar.
By solving an inequality, we will see that for more than 12 tons of sugar, the first company will be the cheaper option.
For how many tons of sugar is the first company a better option?
We know that the first company charges a fixed amount of $1503, plus $125.25 for each ton of sugar, then the total cost for x tons of sugar is:
f(x) = $1503 + $125.2*x
While the second company only charges $250.50 for each ton of sugar, then the cost for x tons of sugar is:
g(x) = $250.50*x
The first company will be a better option for all the values of x such that the following inequality is true:
f(x) < g(x)
Replacing the functions we will get:
$1503 + $125.2*x < $250.50*x
Now we can solve that inequality for x.
$1503 < $250.50*x - $125.25*x
$1503 < $125.25*x
$1503/$125.25 < x
12 < x
So for more than 12 tons of sugar, company one is the best option.

Answer:
x = 121 degrees
y = 59 degrees
w = 59 degrees
z = 53 degrees
v = 121 degrees
Step-by-step explanation:
31 + 90 + w = 180 ==> these three angles are in the top left triangle.
Triangles add up to 180 degrees
121 + w = 180 ==> solve for w
w = 59 degrees
y = w ==> these angles are opposite adjacent angles; they are congruent
y = 59 degrees ==> Both angles are equal. So both angles are 59 degrees
68 + y + z = 180 ==> triangles add up to 180 degrees
68 + 59 + z = 180 ==> plugin 59 for y
127 + z = 180 ==> solve for z
z = 53 degrees ==> subtract 137 on both sides
w + x = 180 ==> w and x are on a straight line.
Straight lines add up to 180 degrees.
59 + x = 180 ==> plugin 59 for w
x = 121 degrees ==> subtract 59 on both sides
v + y = 180 ==> v and y are also on a straight line.
v + 59 = 180 ==> plugin 59 for y
v = 121 degrees ==> subtract 59 on both sides
x = 121 degrees
y = 59 degrees
w = 59 degrees
z = 53 degrees
v = 121 degrees
