describe the transformations that produce the graph of g(x)=1/2(x-4)^3+5 from the graph of the parent function f(x)=x^3 give the order in which they must be preformed to obtain the correct graph
Answers
Notice the function f(x) = (x - 4)³ that a value '4' is subtracted from 'x' ⇒ This means the function f(x) is translated four units to the right.
Then the function f(x) = ¹/₂ (x - 4)³, the function (x - 4)³ is halved vertically ⇒ Half the y-coordinate
Then the function f(x) = ¹/₂ (x - 4)³ + 5 that a value '5' is added to ¹/₂ (x - 4)³ ⇒ This means the function f(x) is translated five units up
So the order of transformation that is happening to f(x) = x³ is translation four units to the right, half the y-coordinate, then translate 5 units up.

Which statement describes the term salary? Salary refers to the fixed amount paid on a daily basis. Salary refers to the varying amount paid on a daily basis. Salary refers to the fixed amount paid on a weekly, bi-weekly, or monthly basis.
Answers
Answer with explanation:
The Meaning of word "Salary " is the Remuneration that you get for converting your energy for obtaining that resources which you don't have ,so you work for others who has other resources or can give you a way to obtain that resources,due to the reason that, you want to keep yourself Mentally as well as physically Healthy.
In today's world money is used for exchange of different goods,in the system created by Humans.So, Remuneration is replaced by "money".
Salary Varies ,on the work you are doing.Because different kind of work requires different amount of energy.So, you get payment according to the work you are doing .
Usually you have to work for five days in a week to get the payment for number of hours worked on each day.
Employee or workers get payment for number of hours worked on daily basis also.
But the word Salary is generally used
"Salary refers to the fixed amount paid on a weekly, bi-weekly, or monthly basis".

Your friend has $80 when he goes to the fair. He spends $4 to enter the fair and $12 on food. Rides at the fair cost $1.25 per ride. Which function can be used to determine how much money he has left over after x rides? (1 point)
f(x) = 1.25x + 64
f(x) = −16x + $80
f(x) = −1.25x + 64
f(x) = −1.25x − 64
Answers
so ur function is :
f(x) = -1.25x + 64
A function is a relationship between inputs where each input is related to exactly one output.
The function that is used to determine how much money he has left over after x rides is
f(x) = -1.25x + 64.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
f(x) = 2x + 2 is a function.
f(x) = 3x + 6 is a function.
We have,
Total amount = $80
Cost of entering the fair = $4
Cost on food = $12
Cost per ride = $1.25
The money left after x rides.
= 80 - (1.25x + 12 + 4)
= 80 - 1.25x - 12 - 4
= 80 - 1.25x - 16
= 64 - 1.25x
= -1.25 + 64
The function to determine money left can be represented as:
f(x) = -1.25x + 64
Thus,
The function that is used to determine how much money he has left over after x rides is
f(x) = -1.25x + 64.

Let's plug in "12" for "f(x)" since they tell us:
12 = x +2.
Now, in order to get "x" by itself, we add 2 to each sides:
12 +2 = x, which then becomes x = 14.

D. Plot the Y-intercept (0,1/2) and use the slope of 3 to find a second point
Answers
we have
[tex]y=\frac{1}{2}x+3[/tex]
we know that
the slope m of the line is equal to
[tex]m=\frac{1}{2}[/tex]
Find the x-intercept
The x-intercept is the value of x when the value of y is equal to zero
so

[tex]0=\frac{1}{2}x+3[/tex]
[tex]x=-6[/tex]
The x-intercept is the point [tex](-6,0)[/tex]
Find the y-intercept
The y-intercept is the value of y when the value of x is equal to zero
so
For [tex]x=0[/tex] find the value of y
[tex]y=\frac{1}{2}*0+3[/tex]
[tex]y=3[/tex]
The y-intercept is the point [tex](0,3)[/tex]
therefore
the answer is the option
B. Plot the Y-intercept (0,3) and use the slope of 1/2 to find a second point
Final answer:
To graph the line y = 1/2x + 3, plot the y-intercept (0,3) and use the slope of 1/2 to find another point on the line.
Explanation:
The correct procedure to graph the line represented by the equation y = ½x + 3 is to start by plotting the y-intercept and then using the slope to find a second point. The y-intercept is the point where the line crosses the y-axis. In this equation, the y-intercept is (0, 3) because when x is 0, y is 3. The slope of the line is ½, which means that for every 1 unit increase in x, y increases by ½ a unit. Therefore, starting at the y-intercept (0, 3), you can go up ½ unit and right 1 unit to find another point on the line.
The correct answer to the multiple-choice question is:
B. Plot the Y-intercept (0,3) and use the slope of 1/2 to find a second point

A. Find their mistake and explain what they did wrong.
B. Show the correct solution.
Answers
When simplifying radicals, it's essential to break down the number under the radical into its prime factors, pair them off when possible, and bring paired numbers out from under the radical to fully simplify. Without the exact problem that Jim Shu attempted, we can't pinpoint his mistake, but we noted a common error in simplification. Using √18 as an example, the correct simplification would result in 3√2.
Explanation:Without the specific problem that Jim Shu attempted to solve, it is impossible to pinpoint the exact mistake he made. However, a common mistake when simplifying radicals is not properly simplifying the radical into its smallest possible terms. For example, if Jim Shu was trying to simplify √18, but he left it as √9 * 2 instead of converting it into 3√2, then he did not correctly simplify the radical. It is important to break down the number under the radical into its prime factors then pair them off when possible to simplify the radical to its most simple form.
The correct solution for √18, as an example, would be to break down 18 into prime factors (2,3,3), pair them off into a 3 and pull it out from under the radical leaving you with the correctly simplified radical, 3√2.

Answers
A quadratic polynomial can have 0, 1, or 2 real roots, including repeated roots. The roots are determined by the discriminant. Numbers 4, 5, or 6 are not possible numbers of real roots for a quadratic polynomial.
Explanation:In Mathematics, specifically in Algebra, a quadratic polynomial with real coefficients can have either 0, 1, or 2 real roots, including any repeated roots. The number of roots is determined by the discriminant (the value under the square root in the quadratic formula). If the discriminant is greater than 0, the quadratic has 2 real roots. If it equals 0, there is 1 real root (a repeated root), and if it is less than 0, there are no real roots (there are 2 complex roots instead). Consequently, the possible number of real roots for a quadratic polynomial is not 4, 5, or 6.

A quadratic polynomial with real coefficients can have 0, 1, or 2 real roots. Only '0 real roots' is a valid choice. This is determined based on the discriminant of the quadratic equation.
A quadratic polynomial with real coefficients is of the form [tex]\( ax^2 + bx + c = 0 \)[/tex], where ( a, b, ) and ( c ) are real numbers.
The number of real roots of a quadratic polynomial can be determined by its discriminant, [tex]\( \Delta = b^2 - 4ac \)[/tex]:
1. If [tex]\( \Delta[/tex] > 0, the polynomial has two distinct real roots.
2. If [tex]\( \Delta[/tex] = 0, the polynomial has one real root (a repeated root).
3. If [tex]\( \Delta[/tex] < 0, the polynomial has no real roots (it has two complex conjugate roots).
Based on this, the possible number of real roots, including repeated roots, for a quadratic polynomial with real coefficients are:
- ( 0 ) (when the discriminant is negative, there are no real roots)
- ( 1 ) (when the discriminant is zero, there is one repeated real root)
- ( 2 ) (when the discriminant is positive, there are two distinct real roots)
Given the options:

The price of a car is £15400 before it is reduced by 8%.
How much does it cost after the reduction
Answers
if we take 15400 to be the 100%, what is 8%?
[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 15400&100\\ x&8 \end{array}\implies \cfrac{15400}{x}=\cfrac{100}{8}\implies \cfrac{15400\cdot 8}{100}=x[/tex]
so, the reduced price of the car is 15400 - x.
The cost of the car after an 8% reduction on the initial price of £15,400 is £14,168. This is found by calculating 8% of the original price and subtracting that amount from the initial price.
The initial price of the car is £15,400. To calculate the price after an 8% reduction, we first find the value of the discount and then subtract it from the original price. An 8% reduction on £15,400 is calculated as follows:
Calculate 8% of £15,400: (8/100) * £15,400 = £1232.Subtract the discount from the original price: £15,400 - £1232 = £14,168.Therefore, as per the above explaination, the cost of the car after the reduction is £14,168.
