The percent of change from 9 points to 4 points is approximate -55.6%, indicating a decrease of 55.6%.
What is the Percent of change?
The percent of change is a measure that compares the difference between two values to the original, or initial, value. It is usually expressed as a percentage and indicates how much a value has increased or decreased from its initial value.
To find the percent of change from 9 points to 4 points, we need to first calculate the amount of change, which is the difference between the final value (4 points) and the initial value (9 points):
Amount of change = Final value - Initial value = 4 - 9 = -5
The negative sign indicates a decrease in value.
Next, we can calculate the percent of change using the formula:
Percent change = (Amount of change / Initial value) x 100%
Substituting the values we get:
Percent change = (-5 / 9) x 100% ≈ -55.6%
Hence, the percent of change from 9 points to 4 points is approximate -55.6%, indicating a decrease of 55.6%.

Describe the long run behavior of f(p)=(p+1)^3(p+4)^3(p-1)
Answer:
Step-by-step explanation:
The long-run behavior of a function can be determined by examining its asymptotes and the behavior of the function near these asymptotes.
For the function f(p)=(p+1)^3(p+4)^3(p-1), there are three points to consider as possible asymptotes: p = -1, p = -4, and p = 1.
At p = -1, the factor (p-1) is equal to zero, so the function has a vertical asymptote there. This means that as p approaches -1 from either side, the function will approach infinity.
At p = -4, the factor (p+4)^3 is equal to zero, so the function also has a vertical asymptote there. Similarly, as p approaches -4 from either side, the function will approach infinity.
At p = 1, the factor (p+1)^3 is equal to zero, so the function has another vertical asymptote there. In this case, as p approaches 1 from either side, the function will approach negative infinity.
So, the long-run behavior of the function can be described as follows:
The function approaches infinity as p approaches -1 or -4 from either side.
The function approaches negative infinity as p approaches 1 from either side.
Therefore, the long-run behavior of f(p)=(p+1)^3(p+4)^3(p-1) is characterized by three vertical asymptotes at p = -1, p = -4, and p = 1.
Answer:

====================================================
Explanation:
Each factor is a cubic of degree 3.
The degree of the entire polynomial is 3+3+3 = 9.
Since the degree is odd and the leading coefficient is positive, this means the graph falls to the left and rises to the right.
"falls to the left" means [tex]\text{As } p \to -\infty, f(p) \to -\infty[/tex]
"rises to the right" means [tex]\text{As } p \to \infty, f(p) \to \infty[/tex]

A business must budget its money. Fractions for each part of one store's budget are listed below.
Which of the following comparisons is TRUE?
Attention Grabbers Bookstore Budget
Advertising 1/6
Rent 7/12
Supplies 1/4
A] The bookstore spends more on advertising than rent.
b} The bookstore spends more on supplies than advertising.
c}The bookstore spends more on advertising than supplies.
d]The bookstore spends more on supplies than rent.
==========================================================
Explanation:
Let's go through each answer choice to see which are true and which are false.
A.
The fractions for advertising and rent are 1/6 and 7/12 respectively. The LCD is 12, so let's get 1/6 to have a denominator of 12. Multiply top and bottom by 2 to get 1/6 = 2/12.
Now we can compare the fractions 2/12 (aka 1/6) and 7/12. Clearly 7/12 is larger. It's like saying "having 7 slices of pizza is more than 2 slices of pizza". Therefore, the claim that more was spent on advertising compared to rent is false.
----------------------
B.
1/4 = 3/12 when multiplying top and bottom by 3
3/12 was spent on supplies and 2/12 was spent on advertising
We see that more was spent on supplies, so claim B is true
----------------------
C.
This claim is false because it contradicts claim B.
Another way to see why it's false is to use a calculator to get these decimal values
advertising = 1/6 = 0.17 approximatelysupplies = 1/4 = 0.25 exactlySince 0.17 is not larger than 0.25, this means 1/6 is not larger than 1/4.
----------------------
D.
We could use any of the methods mentioned in the previous sections, but I'll go another route.
For now assume that the fractions for supplies and rent (1/4 and 7/12 respectively) are equal.
Let's use cross multiplication to say the following:
1/4 = 7/12
1*12 = 4*7
12 = 28
Clearly the two sides are different so the original fractions aren't equal. To fix this error, replace each equal sign with a "less than" sign like so
1/4 < 7/12
1*12 < 4*7
12 < 28
Think of it like working backward up the chain. Start with 12 < 28 which is clearly true, and you can work backwards to end up with 1/4 < 7/12.
The fact we end up with 1/4 < 7/12 shows the claim "The bookstore spends more on supplies than rent" is false. It's the other way around: the bookstore spent more on rent compared to supplies.
----------------------
Summary: We found only choice B to be true. The other statements were false.
In a class of 50 students, 20 play hockey and 35 play football . 10 students play both hockey and football.

What is a mathematical expression?A mathematical expression combines constants, numbers, variables, and values with mathematical operations without adding the equation symbol (=).
When the equation symbol is added to mathematical expressions, they become an equation.
In this situation, the compound interest final amount is depicted like an exponential growth function as follows:
f(x) = a(1+r)ˣ
f(x) = exponential growth function
a = initial amount

Carlos had $400. He decided to spent 40% of it on clothes, and 50% of the remaining money on video games. How much money did Carlos spend? How much does Carlos have left?
Answer:
Step-by-step explanation:
We can start by finding how much money Carlos spent on clothes. To do this, we simply multiply the original amount of $400 by 40%:
Clothes = $400 * 40% = $400 * 0.40 = $160
Next, we find how much money Carlos has left after spending on clothes. To do this, we subtract the amount spent on clothes from the original amount:
Remaining Money = $400 - $160 = $240
Finally, we find how much money Carlos spent on video games. To do this, we multiply the remaining money by 50%:
Video Games = $240 * 50% = $240 * 0.50 = $120
So, in total, Carlos spent $160 on clothes and $120 on video games, for a total of $160 + $120 = $280.
And Carlos has $400 - $280 = $120 left.
After spending 40% of the $400 on clothes, Carlos has $400 x (100 - 40) / 100 = $240 left.
Next, he spent 50% of the remaining $240 on video games, which is $240 x 50 / 100 = $120.
Therefore, Carlos spent a total of $400 - $240 = $160.
Finally, Carlos has $240 - $120 = $120 left.

Find the x - and y -components of the vector d⃗ = (5.0 km , 29 ∘ left of +y -axis).
Express your answer in kilometers. Enter the x and y components of the vector separated by a comma.
The x- and y-components of the vector [tex]\mathbf{\hat d }[/tex] are approximately -2.25 km and 4.30 km, respectively.
What is vector?In physics and mathematics, a vector is a mathematical object that has both magnitude and direction. Vectors are often represented by arrows, with the length of the arrow indicating the magnitude of the vector, and the direction of the arrow indicating the direction of the vector.
For example, the velocity of a moving object is a vector quantity, because it has both a magnitude (the speed of the object) and a direction (the direction in which the object is moving).
To find the x-components and y-components of the vector [tex]\mathbf{\hat d }[/tex] = (5.0 km, 29° left of +y-axis), we can use trigonometry.
The magnitude (or length) of the vector is given by the first component, which is 5.0 km.
The angle between the vector and the positive y-axis is 29° left of +y-axis, which means it forms a 61∘ angle with the negative y-axis (since 29∘ + 61° = 90°).
The x-component of the vector can be found by multiplying the magnitude by the cosine of the angle:
x-component = magnitude x cos(angle) = 5.0 km x cos(61°) ≈ -2.25 km
The negative sign indicates that the x-component is in the opposite direction of the positive x-axis.
The y-component of the vector can be found by multiplying the magnitude by the sine of the angle:
y-component = magnitude x sin(angle) = 5.0 km x sin(61°) ≈ 4.30 km
Therefore, the x- and y-components of the vector [tex]\mathbf{\hat d }[/tex] are approximately -2.25 km and 4.30 km, respectively.
Expressed as an ordered pair, the components are (-2.25 km, 4.30 km).

Each worker at a store gets paid $15.90 for that first 40 hours worked. After 40 hours, they earn time and a half wages. Every employee has a 28% of his/her gross pay deducted for taxes, insurance etc. how much of a net pay does each worker take home?
Each worker would take home a net pay of $586.71.
What is the net pay?
The net pay is the amount of money that an employee takes home after all deductions have been made from their gross pay. Gross pay is the total amount of money an employee earns before taxes and other deductions are taken out.
To calculate net pay, you need to subtract all the required deductions from the employee's gross pay.
To calculate the net pay for each worker, we first need to determine their gross pay. The gross pay will depend on the number of hours they worked and whether they worked any overtime.
For the first 40 hours worked, each worker earns $15.90 per hour, so their gross pay for those hours would be:
Gross Pay for 40 hours = $15.90/hour x 40 hours = $636
For any hours worked beyond 40, the worker earns time and a half wages. This means they earn 1.5 times their regular hourly wage of $15.90, or $23.85 per hour. So, if they worked, for example, 45 hours in total, the additional 5 hours would be paid at the overtime rate, resulting in an additional gross pay of:
Gross Pay for 5 overtime hours = $23.85/hour x 1.5 x 5 hours = $178.88
Therefore, their total gross pay would be:
Total Gross Pay = Gross Pay for 40 hours + Gross Pay for 5 overtime hours = $636 + $178.88 = $814.88
Now, we need to calculate the deductions, which we are told are 28% of the gross pay. So the total deductions would be:
Total Deductions = 28% x $814.88 = $228.17
Finally, to determine the net pay, we need to subtract the total deductions from the gross pay:
Net Pay = Gross Pay - Total Deductions = $814.88 - $228.17 = $586.71
Therefore, each worker would take home a net pay of $586.71.

For a certain company, the cost function for producing x
items is C(x)=30x+200
and the revenue function for selling x
items is R(x)=−0.5(x−80)2+3,200
. The maximum capacity of the company is 130
items.
The profit function P(x)
is the revenue function R(x)
(how much it takes in) minus the cost function C(x)
(how much it spends). In economic models, one typically assumes that a company wants to maximize its profit, or at least make a profit!

The company can choose to produce either 50
or 60
items. What is their profit for each case, and which level of production should they choose?
Profit when producing 50
items =
Number
Profit when producing 60
items =
Number
Can you explain, from our model, why the company makes less profit when producing 10 more units?
Answer: The profit function P(x) can be found by subtracting the cost function C(x) from the revenue function R(x), so:
P(x) = R(x) - C(x) = (-0.5(x-80)^2 + 3,200) - (30x + 200)
The domain of P(x) is the set of all possible values of x for which the profit calculation makes sense. In this case, the company has a maximum capacity of 130 items, so the domain of P(x) is 0 <= x <= 130.
To calculate the profit when producing 50 items and 60 items, we simply plug in these values for x in the profit function:
Profit when producing 50 items = P(50) = (-0.5(50-80)^2 + 3,200) - (30 * 50 + 200) = $2350
Profit when producing 60 items = P(60) = (-0.5(60-80)^2 + 3,200) - (30 * 60 + 200) = $2280
Since the profit is higher for producing 50 items, the company should choose to produce 50 items.
From our model, we can see that as the production increases, the cost also increases linearly with a slope of 30, while the revenue increases parabolically but with a negative slope, meaning that after reaching a certain point, the increase in revenue becomes slower compared to the increase in cost. This is why the profit decreases as the production increases, and therefore the company makes less profit when producing 10 more units.

If the r-value, or correlation coefficient, of a data set is 0.934, what is the
coefficient of determination to three decimal places?
О A. 0.872
• B. 0.834
• C. 0.966
• D. 0.942
If the r-value, or correlation coefficient, of a data set is 0.934, the
coefficient of determination to three decimal places is: A. 0.872.
How to find the coefficient of determination?The coefficient of determination (R-squared) is the square of the correlation coefficient (r) and represents the proportion of the variance in the dependent variable (y) that can be explained by the independent variable (x).
So, to find the coefficient of determination, we need to square the correlation coefficient:
R-squared = r^2
= 0.934^2
= 0.872 (Rounded to three decimal places)
Therefore, the answer is (A) 0.872.

Step-by-step explanation:
We can assume ∠KLJ ≅ MLJ. So we put them equal to each other.
[tex]42=9x-3\\45=9x\\5=x[/tex]
The value of x when an angle of the given figure is given as 9x - 3 is x = 5.
Given a figure.
It is required to find the value of x.
Here, consider the two triangles which are split up in the figure.
Consider the triangles JKL and JML.
Comparing the sides and angles:
JK = JM
KL = ML
JL = JL
So, they are similar.
Each corresponding angles are equal.
Here, the angle corresponding to ∠JLK is ∠JLM.
So, they are equal.
∠JLM = ∠JLK
9x - 3 = 42
Add 3 on both sides.
9x = 45
Divide both sides by 9.
x = 5
Hence, the value of x is 5.

A certain antihistamine is often prescribed for allergies. A typical dose for a 100-pound person is 19 mg every six hours. Complete parts (a) and (b) below. a. Following this dosage, how many 13.2 mg chewable tablets would be taken in a week? b. This antihistamine also comes in a liquid form with a concentration of 13.2 mg/ 10mL. Following the prescribed dosage, how much liquid antihistamine should a 100-pound person take in a week?
A 100-pound person could take mL in a week? this is the question i need answered the most...thank you
Answer: First, let's find out how many times a 100-pound person would take the antihistamine in a week:
Every 6 hours * 24 hours/day = 4 times a day
4 times a day * 7 days/week = 28 times a week
Next, let's find the number of 13.2 mg chewable tablets taken in a week:
A typical dose of 19 mg * 28 doses/week = 532 mg
532 mg / 13.2 mg/tablet = 40 tablets
So, a 100-pound person would take 40 chewable tablets in a week following the prescribed dosage.
Now, let's find the amount of liquid antihistamine to be taken in a week:
A typical dose of 19 mg * 28 doses/week = 532 mg
532 mg / 13.2 mg/10 mL = 40.15 mL
So, a 100-pound person would take 40.15 mL of liquid antihistamine in a week following the prescribed dosage.
