(3, 4) I think it is a solution to the inequality. Because when you graph it (3, 4) looks like it is shaded meaning that it is a solution. (If wrong, I'm sorry)
The inequality that represents the numbers of apples and pears you can buy is 0.40x + 0.65y ≤ 3.50.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
Given;
The cost of the apples = $0.40 per apple
So, the cost of x apples is 0.40x.
The cost of the pears = $0.65 per pear
So, the cost of y pears is 0.65y.
The total cost of the apples and pears is the sum of the cost of the apples and the cost of the pears, which is 0.40x + 0.65y;
Since we can spend at most $3.50 at the market, the total cost of the apples and pears must be less than or equal to $3.50;
Therefore, the inequality that represents the numbers of apples and pears you can buy will be 0.40x + 0.65y ≤ 3.50;

6 3 points F L(2x-48) 32 W Using the diagram above find the value of x and use it to find the measures of all the missing angles. X = type your answer..... m/FOW= m/FLW= m/OLW= = type your answer... type your answer... type your answer.....
The value of x is 80
The measure of angle FOW, m ∠FOW, is 80°
The measure of angle FLW, m ∠FLW, is 112°
The measure of angle OLW, m ∠OLW, is = 68°
Calculating the measure of anglesFrom the question, we are to determine the measure of the missing angles
From the given diagram, we can write that
(2x - 48)° = x° + 32°
Solve for x
(2x - 48)° = x° + 32°
2x° - 48° = x° + 32°
Subtract x° from both sides of the equation
2x° - x° - 48° = x° - x° + 32°
x° - 48° = 32°
Add 48° to both sides of the equation
x° - 48° + 48° = 32° + 48°
x° = 32° + 48°
x° = 80°
Therefore,
x = 80
Calculating the m ∠FOW
m ∠FOW = x°
m ∠FOW = 80°
Calculating the m ∠FLW
m ∠FLW = (2x - 48)°
m ∠FLW = (2(80) - 48)°
m ∠FLW = (160 - 48)°
m ∠FLW = 112°
Calculating the m ∠OLW
m ∠OLW + m ∠FOW + m ∠OWL = 180° (Sum of angles in a triangle)
m ∠OLW + 80° + 32° = 180°
m ∠OLW + 112° = 180°
m ∠OLW = 180° - 112°
m ∠OLW = 68°
Hence, the measure of m ∠OLW is 68°

What is Cantor set type construction?
The Cantor set is a collection of points situated on a single line segment that possesses a variety of odd characteristics.
By deleting the center third of a line segment and then repeating the process with the remaining shorter segments, the Cantor ternary set, the most popular construction, is created. The ternary construction was only briefly described by Cantor as an illustration of a more basic concept—that of a perfect set that isn't dense anywhere.
According to the given question:
The proportion (i.e., measure) of the unit interval that is left can be determined by subtracting the entire length as the Cantor set is defined as the set of points that are not excluded.

The number of sticks in pattern 6 is; 26
The nth term of the sequence formed is; aₙ = 4n + 2
How to find the arithmetic sequence?From the attached image, we see that;
Number of sticks in pattern 1 is 6
Number of sticks in pattern 2 is 10
Number of sticks in pattern 3 is 14
Thus, the sequence will be;
6, 10, 14, ...
This is an AP because the difference is 4.
The formula for the nth term of an AP is;
aₙ = a + (n - 1)d
where;
a is first term
n is position of term
d is common difference
In our sequence, first term; a = 6
Common difference; d = 10 - 6 = 4
Thus, the equation for the nth term is;
aₙ = a + (n - 1)d
aₙ = 6 + (n - 1)4
aₙ = 6 + 4n - 4
aₙ = 4n + 2

(30 points) The fixed costs of manufacturing basketballs in a factory are $1,400.00 per day. The variable costs are $5.25 per basketball. Which of the following
expressions can be used to model the cost of manufacturing b-basketballs in 1 day?
O $1,405.25b
o $5.25b-$1,400.00
O $1,400.00b+$5.25
O $1,400.00-$5.25b
The correct expression to model the cost of manufacturing b basketballs in 1 day is:
O $5.25b-$1,400.00
The fixed costs of manufacturing the basketballs are $1,400.00 per day, and the variable costs are $5.25 per basketball. To find the total cost of manufacturing b basketballs in 1 day, you need to add the fixed costs and the variable costs for each basketball.
The variable costs for b basketballs would be $5.25 * b. To find the total cost, you need to subtract the fixed costs of $1,400.00 from this amount. This can be represented by the expression $5.25b - $1,400.00.
The other expressions do not correctly represent the cost of manufacturing b basketballs in 1 day because they do not correctly account for both the fixed costs and the variable costs.
The quantity (in pounds) of a gourmet ground coffee that is sold by a coffee company at a price of p dollars per pound is Q = f(p).^1(a) What is the meaning of the derivative f^1(8)? What are its units?
The derivative f'(8) gives the rate of change of the quantity (in pounds) of coffee sold as we increase the price (in dollars).
The units of the derivative are always output units from original function input units from original function . For the original function, the output is pounds of coffee sold, and the input is the price in dollars per pound.
Thus the units for f′(8) are pounds dollars/pound.(b) Is f′(8) positive or negative? Explain. We interpret the rate given by the derivative as the input increases, so the price per pound is increasing. From the law of supply and demand, as the price increases, the quantity sold decreases. Thus we expect
f′(8) to be negative.
The answers to both subparts are shown:
(A) The derivative of f'(5) means the pace at which the price per pound changes in relation to the weight of coffee sold at $5 per pound.
(B) The unit of f'(5) is pounds/dollar.
What is derivative?The derivative of a function of a real variable in mathematics assesses how sensitively the function's value changes in response to changes in its argument.
Calculus's core tool is the derivative.
We may find the slope of a function at any point by using its derivative. We can find numerous derivatives by adhering to certain rules.
For instance: A constant value, such as 3, always has a slope of 0.
(A) Meaning of derivative of: f'(5)
We have: Q = f(p) ...(1)
Differentiating Q in relation to p results in:
qQ/dp = f'(p) ...(2)
The rate of change of the price per pound in relation to the volume of coffee sold is implied by equation (2).
If p = 5, we get:
qQ/dp = f'(5) ...(3)
The rate at which the price per pound changes in relation to the amount of coffee sold at $5 per pound is implied by equation (3).
(B) Unit of f'(5):
Equation (3)'s result that qQ/dp = f'(5) suggests that f'(5) units are pounds/dollar.
Therefore, the answers to both subparts are shown:
(A) The derivative of f'(5) means the pace at which the price per pound changes in relation to the weight of coffee sold at $5 per pound.
(B) The unit of f'(5) is pounds/dollar.

[tex]\begin{aligned} \textsf{Solutions}: \quad x &= 120^{\circ}\\y &= 60^{\circ}\end{aligned}[/tex]
Step-by-step explanation:
An obtuse angle is greater then 90° and less than 180°.
An acute angle is less than 90°.
Therefore, from inspection of the given diagram:
x = obtuse angley = acute angleIf the measures of the acute angles are one-half times the measures of the obtuse angles:
[tex]\implies x=\dfrac{1}{2}y[/tex]
Angles in a quadrilateral sum to 360°.
[tex]\implies 2x+2y=360[/tex]
Therefore, the system of equations is:
[tex]\begin{cases}x=\dfrac{1}{2}y\\\\2x+2y=360\end{cases}[/tex]
Substitute the first equation into the second equation and solve for y:
[tex]\implies 2\left(\dfrac{1}{2}y\right)+2y=360[/tex]
[tex]\implies y+2y=360[/tex]
[tex]\implies 3y=360[/tex]
[tex]\implies \dfrac{3y}{3}=\dfrac{360}{3}[/tex]

6x+6y=90 9x+2y=79 What pair of numbers solves the system?
Answer:
(7, 8)
Step-by-step explanation:
equation 1: [tex]6x+6y=90[/tex]
equation 2: [tex]9x+2y=79[/tex]
This system of equations can be solved for using the elimination method.
First, multiply both sides of the first equation by 3/2 to match the number of x's in both equations so that when we subtract the first equation from the second, the x's cancel and we can solve for y.
[tex]\left(\dfrac{3}{2}\right)\left(6x+6y\right)=(90)\left(\dfrac{3}{2}\right)[/tex]
[tex]9x + 9y = 135[/tex]
Next, subtract this from the second equation.
[tex]9x+2y=79[/tex] ← eq. 2
[tex]\underline{- (9x+9y=135)}[/tex] ← modified eq. 1
[tex]0 - \, 7y \, = -56[/tex]
Then, solve for y by dividing by 7.
[tex]7y = 56\\\overline{\, 7 \ } \ \ \ \ \overline{\ 7 \: }[/tex]
[tex]y=8[/tex]
So, the y-coordinate of the solution pair is 8.
Now that we've solved for the y, all we have to do to get x is plug the solved y-value back into one of the equations. I'll use the first equation.
[tex]6x+6y=90[/tex]
[tex]6x + 6(8) = 90[/tex]
↓ multiplying out 6 and 8
[tex]6x + 48 = 90[/tex]
↓ subtracting 48 from both sides
[tex]6x = 90 - 48[/tex]
[tex]6x = 42\\\overline{\: 6 \: } \ \ \ \ \, \overline{\: 6 \: }[/tex]
[tex]x = 7[/tex]
So, the x-coordinate of the solution pair is 7.
Finally, put the x- and y-coordinates together into an ordered pair in the form [tex](x, y)[/tex].

Answer:
(7, 8) is the required pair of numbers---------------------------
Given system6x + 6y = 90, 9x + 2y = 79.Solve it by substitutionFirst, simplify the first equation by dividing all terms by 6:
x + y = 15Then solve it for y:
y = 15 - xNow, substitute this into the second equation:
9x + 2(15 - x) = 799x + 30 - 2x = 797x = 79 - 307x = 49x = 7Finally, find the value of y:
y = 15 - 7y = 8The pair of numbers is (7, 8).
Calculate the area, in square units, bounded by f(x) = 3x^3-3x^2-x+8 and g(x) = 2x^3 - 10x^2 + 29x + 8 over the interval [1, 5].
The area bounded by f(x)=3x³-3x²-x+8, g(x) = 2x³- 10x² + 29x+8
over the interval [1, 5] is 164 square units.
What is meant by a function?Exactly one element of Y is assigned to each element of X via a mathematical function from a set X to a set Y. The domain and codomain of the function are, respectively, the sets X and Y as a whole.
The first presentation of the idea of function that is known about was developed by two Persian mathematicians, Al-Biruni and Sharaf al-Din al-Tusi. Originally, functions were used to depict the desired relationship between two varying values. For example, time affects the position of a planet. Up to the 19th century, the functions that were taken into consideration were differentiable.
Given,
f(x)=3x³-3x²-x+8
g(x) = 2x³- 10x² + 29x + 8
And the interval is [1, 5].
By using area formula,
A=[tex]\int\limits^a_b {f(x)-g(x)} \, dx[/tex]
A=[tex]\int\limits^a_b[/tex](Upper function-Lower function)dx
A=[tex]\int\limits^3_1[/tex][g(x)-f(x)]dx+[tex]\int\limits^5_3[/tex][f(x)-g(x)]dx
A=[tex]\int\limits^3_1[/tex](-x³-7x²+30x)dx+[tex]\int\limits^5_3[/tex](x³+7x²-30x)dx
A= (118/3)+(374/3)
A=164 square units.
Therefore, the area bounded by f(x)=3x³-3x²-x+8, g(x) = 2x³- 10x² + 29x+8
over the interval [1, 5] is 164 square units.

The t distribution is a family of similar probability distributions, with each individual distribution depending on a parameter known as the degrees of freedom.
How are the degrees of freedom determined?
When calculating degrees of freedom, one is subtracted from the total number of items in the data sample. Degrees of freedom are frequently addressed in relation to different types of statistical hypothesis testing, like a chi-square.The number of independent bits of information required to construct a statistic is called the degrees of freedom, which is frequently denoted by the letters v or df. It is determined by subtracting the number of constraints from the sample size.Finding essential cutoff values for inferential statistical tests requires consideration of the degree of freedom. Degrees of freedom often (but not always) relate to sample size depending on the sort of study you conduct.Hence, the t distribution is a family of similar probability distributions, with each individual distribution depending on a parameter known as the degrees of freedom.

the Discriminant will always be greater than or equal to zero. This means that the polynomial has at least one real root.
Let f(x) = a0 + a1x + a2x2 + a3x3 be a polynomial function of odd degree 3.
We know that the degree of a polynomial is the highest power of the variable in the equation. Since the degree of f(x) is 3, then a3 ≠ 0.
Now, consider the Discriminant of the polynomial, which is defined as the expression below:
Discriminant = b2 - 4ac
In this case, b2 = a2^2, c = a0 and a = a3, thus the Discriminant is:
Discriminant = a2^2 - 4a0a3
Since a3 ≠ 0 (as mentioned before), the Discriminant will always be greater than or equal to zero. This means that the polynomial has at least one real root.

What is differential equation?A differential equation in mathematics is an equation that connects the derivatives of one or more unknown functions.
Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three. Due to the prevalence of these relationships, differential equations are widely used in many fields, including engineering, physics, economics, and biology.
The primary focus of studying differential equations is on the solutions—the collection of functions that satisfy each equation—as well as the characteristics of those solutions.
Only the most basic differential equations can be solved using explicit formulas, but many features of a particular differential equation's solutions can be deduced without doing an exact calculation.

Find a function formula for f. b. Find a function formula for g. C. If Carissa was expecting to work for 5 years before going back to school, which company do you think she should work for? Use your functions to justify your answer. I d. If Carissa was expecting to work for 10 years before going back to school, which company do you think she should work for? Use your functions to justify your answer.
Let f(t) be 51000+ (2100)t which represent Chelsea's salary at Company A and g(t) be 45000(1.041)t which Chelsea salary at Company B.
Chelsea's offer from company A includes a raise of $2100 annually and a starting salary of $45,000.
Since the increase is constant, the salary of Chelsea from Company A is a linear function, as can be seen here.
f(t) is salary of chelsea from company A after t years.
f(t) = 45000+ (2100)t
The offer made to Chelsea by company B includes a starting salary of $45,000 and an annual raise of 4.1%.
we can see here that raise is exponential, so raise is:
(1+4.1/100) = (1+0.041) = (1.041) per year.
Consequently, the salary of Chelsea from Company B is a function that is exponential.
g(t) is salary of chelsea from company B after t years.
g(t) = 45000(1.041)t

If i have 2 apples and i get 69 times that, than i give three-ninths of it to a friend, how much would i have left?
Answer:
92 apples remaining
Step-by-step explanation:
2 * 69 = 138 apples
138 * (3/9) =
138 * (1/3) =
138 * 1/3 =
138/3 = 46 apples
138 - 46 = 92 apples remaining
Answer:
you have 2 apples
then you got it 69 times= 2×69 = 138
then you give 3 ninths to a friend
138/9 = 15.33
you gave it 3 one-ninths = 3× 15.33 = 46
so must be left with 138-46 = 92

Please show all your work.
Answer:
x = 7/3.
Step-by-step explanation:
DE is parallel to BC and AD= DB and AD = EC.
So, AD/DB = (x+1)/(4x-6)
(x + 1)/(4x - 6) = 1
x + 1 = 4x - 6
1 + 6 = 4x - x
3x = 7
x = 7/3.

What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
From the ideal gas equation, we know that,
Volume is directly proportional to the temperature,
So,
V₁ / V₂ = T₁ / T₂
Where,
V₁ and T₁ are the initial pressure and temperature,
V₂ and T₂ are the final pressure and temperature.
Substitute the values,
8 / V₂ = 400 / 200
V₂ = 4
Thus, the volume of the gas becomes 4L. Option B is correct.
