We can say that after answering the offered question Therefore, the proportionality constant of proportionality in this scenario is 11.25.
what is proportionality?Proportionate relationships are those that have the same ratio every time. For example, the average number of apples per tree defines how many trees are in an orchard and how many apples are in an apple harvest. Proportional refers to a linear relationship between two numbers or variables in mathematics. When the first quantity doubles, the second quantity doubles as well. When one of the variables decreases to 1/100th of its previous value, the other falls as well. When two quantities are proportional, it means that when one rises, the other rises as well, and the ratio between the two remains constant at all values. The diameter and circumference of a circle serve as an example.
In this case, we may use the following formula to calculate the proportionality constant:
proportionality constant = output/input
where the output is John's pay and the input is the number of hours he worked.
As a result, the proportionality constant is:
Paycheck/hours worked = proportionality constant
proportionality constant = 450/40
proportionality constant = 11.25
As a result, the proportionality constant in this scenario is 11.25.

What is the inverse of a function?An inverse function maps the output, or y-value of a function to the input value or x-value of the function.
2. A. f(x) = 3/(7·x + 1)
The inverse function can be found as follows;
Let f(x) = y
y = 3/(7·x + 1)
(7·x + 1) = 3/y
7·x = (3/y) - 1 = (3 - y)/y
x = (3 - y)/(7·y)
Plugging in x = f⁻¹(x), and y = x, to get;
The inverse of the function; f⁻¹(x) = (3 - x)/(7·x)B. g(x) = (3 - x)/(7·x)
f(x) = 3/(7·x + 1)
f(g(x)) = 3/(7 × ((3 - x)/(7·x)) + 1) = 3/(((3 - x)/(x)) + 1) = 3/(3/x - 1 + 1)

Standard deviation : What is it?Statistics uses variance as a gauge of difference. The image of that figure is used to compute the average variance between the collection and the mean. It includes those data points itself into the calculations, unlike many other real measures of variability, by comparing also every figure to the mean.
Here,
Since the population standard deviation is unknown and the sample number is less than 30, we can use a t-distribution to build the confidence interval. The confidence interval's calculation is:
=>CI = x t /2 × (s/n).
Since we need a 99% confidence range, = 0.01 and /2 = 0.005, and (n-1) = (49-1) = 48 is the number of degrees of freedom.
We discover that t/2 = 2.678 using the t-distribution table with 48 degrees of freedom and 0.005 significance level.
When we enter the numbers, we obtain:
=> CI = 3.1 ± 2.678 * (16.5/√49) = 3.1 ± 7.34
The estimated mean net change in LDL cholesterol following treatment, according to the 99% confidence range, is (4.24, 10.44) mg/dL.

A newspaper editor starts a retirement savings plan in which $275 per month is deposited at the beginning of each month into an account that earns an annual interest rate of 6.4% compounded monthly. Find the value of this investment (in dollars) after 20 years. (Round your answer to the nearest cent.)
Answer:
Step-by-step explanation:
x= 20 (12) =240, Interest%= 6.4, Pv + 0, PMT= 275,temporarily skip FV,P/Y and C/Y= 12,
After 20 years, the value is $133,970.26
The simple interest value of the investment after 20 years is approximately $30,637.45
What do you mean by future value?Future value (FV) is the value of an investment at a future date, based on a series of regular payments (or a lump sum) and assuming a certain interest rate over a period of time. In other words, it's the amount of money an investment will be worth after earning a certain rate of interest over a certain period of time.
What is simple interest?Simple interest is a method of calculating interest on a loan or investment, where interest is only charged on the original principal amount. In other words, the interest is not compounded over time.
In the given question:
We can use the formula for the future value of an annuity:
FV = PMT x [(1 + r/n)^(n*t) - 1] / (r/n)
where: FV = future value
PMT = monthly payment
r = annual interest rate
n = number of compounding periods per year
t = number of years
Plugging in the given values, we have:
FV = 275 x [(1 + 0.064/12)^(12*20) - 1] / (0.064/12)
FV = 275 x (1.00533²⁴⁰ - 1) / 0.00533
FV = 275 x 111.034
FV = 30,637.45
Therefore, the value of the investment after 20 years is approximately $30,637.45.

trey paid 42 dollars for 2/3 ton of concrete. he wants to know the price of 3 tons of concrete.
Answer:
To find the price of 3 tons of concrete, we need to first figure out how much Trey paid per ton of concrete.
Since Trey paid 42 dollars for 2/3 ton of concrete, we can set up a proportion:
2/3 ton = 42 dollars
1 ton = x dollars
To solve for x, we can cross-multiply:
(2/3) * x = 42 * 1
2x = 126
x = 63
So, Trey paid 63 dollars per ton of concrete.
To find the price of 3 tons of concrete, we can multiply the cost per ton by the number of tons:
3 tons * $63/ton = $189
Therefore, the price of 3 tons of concrete is $189.
For each quadratic function below, use the idea of completing the square to write it in graphing form. Then state the vertex of each parabola. a. f(x)=x² +6x+15 b. y= x^2-4x+9 c. f(x)= x² +8x d. y=x² - 4x+9
please help i don't want answers just somebody to explain this in a way that makes sense help
Note that the graphing form and vertex of each quadratic function are given as follows:
a) for f(x)=x² +6x+15, the graphing form of the quadratic function is f(x) = (x + 3)² + 6. The vertex is (-3, 6).
b) for y= x²-4x+9 the graphing form of the quadratic function is y = (x - 2)² + 5. The vertex is (2, 5).
c) for f(x)= x² +8x, the graphing form of the quadratic function is f(x) = (x + 4)² - 16. The vertex is (-4, -16).
d) for . y=x² - 4x+9, the graphing form of the quadratic function is y = (x - 2)² + 5. The vertex is (2, 5).
a. To complete the square for the quadratic function f(x)=x² +6x+15, we add and subtract the square of half of the coefficient of x, which is (6/2)² = 9:
f(x) = x² + 6x + 15
= (x² + 6x + 9) + 6
= (x + 3)² + 6
Therefore, the graphing form of the quadratic function is f(x) = (x + 3)² + 6. The vertex is (-3, 6).
b. To complete the square for the quadratic function y= x^2-4x+9, we add and subtract the square of half of the coefficient of x, which is (-4/2)² = 4:
y = x^2 - 4x + 9
= (x^2 - 4x + 4) + 5
= (x - 2)² + 5
Therefore, the graphing form of the quadratic function is y = (x - 2)² + 5. The vertex is (2, 5).
c. To complete the square for the quadratic function f(x)= x² +8x, we add and subtract the square of half of the coefficient of x, which is (8/2)² = 16:
f(x) = x² + 8x
= (x² + 8x + 16) - 16
= (x + 4)² - 16
Therefore, the graphing form of the quadratic function is f(x) = (x + 4)² - 16. The vertex is (-4, -16).
d. To complete the square for the quadratic function y=x² - 4x+9, we add and subtract the square of half of the coefficient of x, which is (-4/2)² = 4:
y = x² - 4x + 9
= (x² - 4x + 4) + 5
= (x - 2)² + 5
Therefore, the graphing form of the quadratic function is y = (x - 2)² + 5. The vertex is (2, 5).

Answer:
The answer is (f.g)(x) = 12x^2 - 9.
Step-by-step explanation:
To find (f.g)(x), we need to apply the composition of functions formula, which is:
(f.g)(x) = f(g(x))
First, we need to find g(x):
g(x) = 3x^2
Now, we need to plug g(x) into f(x) in place of x:
f(g(x)) = 4(g(x)) - 9
= 4(3x^2) - 9
= 12x^2 - 9
Therefore, (f.g)(x) = 12x^2 - 9.

We're asked to prove that ΔSTV ≅ ΔTUW.
Let's begin by reviewing what was given to us.
Line Segment SV ≅ & ║ (Congruent and Parallel With) Line Segment TW.∠SVT ≅∠TWU.SV ≅ TW.Because we already have one side and an angle congruent, we need to prove that another angle or side is congruent.
Our goal is to find a Congruency Postulate to prove that ΔSTV ≅ ΔTUW.
As we can see in the diagram, ∠STV ≅ ∠UTV as they're vertical angles. This is possible because Line Segment SV ≅ & ║ Line Segment TW.
We are now able to prove that ΔSTV ≅ ΔTUW with the Angle-Side-Angle Triangle Congruency Postulate (ASA). We proved, and were given 2 angles, and 1 side.
Summary:
∠STV ≅ ∠UTV | Vertical Angles.
ΔSTV ≅ ΔTUW | ASA.
What is the radius of the circle that is centered at (2, −3) and passes through the point (−1, −6)?
Answer:
We can use the distance formula to find the distance between the center of the circle (2, -3) and the point (-1, -6), which should be equal to the radius of the circle.
Step-by-step explanation:
Distance = √[(x2 - x1)² + (y2 - y1)²]
Distance = √[(-1 - 2)² + (-6 - (-3))²]
Distance = √[(-3)² + (-3)²]
Distance = √(18)
So the radius of the circle is equal to √(18) or approximately 4.24.
In a certain study, the odds against a car crash on the road are stated as "22:3". What is the probability of a car crash on the road? Enter the probability as a reduced fraction.
Therefore, the likelihood of a vehicle accident just on road is 3/25. The ultimate solution is 3/25 because there is no other way to simplify this fraction.
What is the probability calculation?The probability is typically defined as the proportion of favourable findings to all results inside the poll area. The formula for probability of an event is P(E) = (Number of positive occurrences) (Sample space).
If the odds against a car crash on the road are stated as "22:3", it means that for every 22 unfavorable outcomes (no car crash), there are 3 favorable outcomes (car crash).
The total number of outcomes is 22 + 3 = 25.
Therefore, the probability of a car crash on the road is:
3 favorable outcomes / 25 total outcomes = 3/25
So, the probability of a car crash on the road is 3/25. This fraction cannot be reduced further, so the final answer is 3/25.

According to the given information:The three angles are given as ∠1=84°, ∠2=41°, ∠3=2x+15°.
Adding three angles
84° + 41° + 2x + 15° = 180° (sum of interior angle is 180°)
140° + 2x = 180°
2x = 180°-140°
2x = 40°
x = 20°

The width of the patio, given the area of the pool and the patio, can be found to be 19. 59 ft
How to find the width ?The area of the pool is said to be equal to the area of the patio which means that to find the width of the patio, you need to find the area of the pool which is :
= 16 ft x 24 ft
= 384 ft ²
The patio is such that the width is the same on every side which makes it a square shaped patio. The width of the patio is therefore:
Width = √ Area of square patio
= √ 384
= 19. 59 ft

i would thank you so much if someone could give me a valid answer please and graph please thank you love
The equation would be y = 0.50x + 10.00, and we have drawn the graph for the same.
What is the graph of the equation?
The graph of an equation is a visual representation of the set of all solutions (points) that satisfy the equation.
To find the equation of the line, we use the slope-intercept form of a linear equation, which is:
y = mx + b
where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).
In this case, we are given the slope of the line (0.50) and the y-intercept (10.00), so we can simply substitute these values into the equation:
y = 0.50x + 10.00
This gives us the equation of the line in slope-intercept form. We can use this equation to find the cost of a cab ride for any distance x (in miles) by substituting the value of x into the equation and solving for y (the fare).
Now let's draw the graph of the equation y = 0.50x + 10.00, we get
Hence, the equation would be y = 0.50x + 10.00, and we have drawn the graph for the same.

I need help on this question
Answer: i think the answer is A
Step-by-step explanation:i think bc i is a quadratic function
Answer: D
Step-by-step explanation:
A and B don't make sense, since the maximum value > 0, and the function is more negative than positive. C and D are our remaining answers. C would be incorrect, since if X reaches \infinity , the function isn't infinite. The only way to make C correct, is a sudden spike in the function to infinity. So, the only correct answer is D.
Hope this helps (please respond if I'm wrong)

find the value of the expression -x^3+3 x^2-x+20 if x=-1
The value of the expression -x³ + 3x² - x + 20 when x = -1 is 23.
What is the value of the given expression when x = -1?Given the expression in the question;
-x³ + 3x² - x + 20
x = -1To determine the value of the expression,
First, we substitute -1 for x in the expression:
-( -1 )³ + 3( -1 )² − ( -1 )) + 20
Next, we simplify each term using the order of operations (also known as PEMDAS):
-( -1 )³ = -( -1 ) = 1
(recall that the exponent is evaluated first, then the negative sign is applied)
3( -1 )² = 3(1) = 3
(recall that the exponent is evaluated first)
-( -1 ) = 1
(recall that subtracting a negative is the same as adding a positive)
Now, putting these simplified terms back into the original expression, we get:
1 + 3 + 1 + 20
Finally, we add these terms together to get the final answer:
23
Therefore, the value of the expression is 23.

Question 3and4 pls
Answer:
In question 3 a triangle can be formed however in question 4 it can't be formed
Step-by-step explanation:
there is a theorem that states that two sides of a triangle when added up should be greater than the third one which isn't true in question 4 as
12+9=21 so its equal to the third side but not greater hence a triangle can't be formed
