Answer:
Step-by-step explanation:
We can use the formula:
average speed = (speed downstream + speed upstream) / 2
We are given the speed downstream is 8 miles per hour and the speed upstream is 2 miles per hour. Therefore,
average speed = (8 + 2) / 2 = 5 miles per hour
So the answer is (B) 5.0 miles per hour to the nearest tenth.

$
(c) Form the profit function P(x) from the cost and revenue functions.
Find maximum profit.
$
(d) What price will maximize the profit? (Round your answer to the nearest cent.)
$
(a) The break-even points are approximately 1,581 and 2,809 units produced.
(b) The maximum revenue is approximately $2,088,931.47.
(c) P(x) = -5/9x² + 919x - 49,400
(d) The price that will maximize the profit is approximately $1,829.17 per unit.
What is the algebraic equations?An algebraic expression is when we use numbers and words in solving a particular mathematical question.
(a) To find the break-even points, we need to find the values of x at which the total revenue equals the total cost. The total revenue is the product of the selling price and the number of units sold, while the total cost is the sum of the fixed cost and the variable cost per unit multiplied by the number of units sold. Thus, we have:
Total revenue = Selling price × Number of units sold = (2148 - 5/9x)x
Total cost = Fixed cost + Variable cost per unit × Number of units sold = 49,400 + (49x/9 + 222)x
Setting the total revenue equal to the total cost, we get:
2148x - 5/9x² = 49,400 + (49x/9 + 222)x
Multiplying both sides by 9, we get:
19332x - 5x² = 445,110
Simplifying, we get:
5x²- 19332x + 445,110 = 0
Using the quadratic formula, we get:
x = (19332 ± sqrt(19332² - 4(5)(445,110))) / (2(5))
x ≈ 2808.6 or x ≈ 1581.4
Hence, the break-even points are approximately 1,581 and 2,809 units produced.
(b) The revenue function is given by:
R(x) = (2148 - 5/9x)x
To find the maximum revenue, we can take the derivative of the revenue function with respect to x, set it equal to zero, and solve for x:
R'(x) = 2148 - 10/9x = 0
x = 19332/10 ≈ 1933.2
Substituting this value of x into the revenue function, we get:
R(1933.2) ≈ $2,088,931.47
Hence, the maximum revenue is approximately $2,088,931.47.
(c) The profit function P(x) is given by:
P(x) = R(x) - C(x) = (2148 - 5/9x)x - (49,400 + (49x/9 + 222)x)
Simplifying, we get:
P(x) = -5/9x² + 919x - 49,400
(d) To find the maximum profit, we can take the derivative of the profit function with respect to x, set it equal to zero, and solve for x:
P'(x) = -10/9x + 919 = 0
x = 8265
Substituting this value of x into the profit function, we get:
P(8265) ≈ $1,077,927.78
Therefore, the maximum profit is approximately $1,077,927.78.
To find the price that will maximize the profit, we need to substitute the value of x into the selling price function:
Selling price = 2148 - 5/9x = 2148 - 5/9(8265) ≈ $1,829.17
Hence, the price that will maximize the profit is approximately $1,829.17 per unit.

What is a linear function?A linear function is a polynomial of degree 1, or a mathematical expression that describes a relation between two variables. It is often written in the form y = mx + b, where m is the slope, x is the independent variable, and b is the y-intercept.
The factored form of a linear equation is the same as the standard form of the equation, with the exception that the coefficients of the variables are each expressed as a product of their prime factors. In the case of y=3x+12, the factored form is (3x+12). The zero of the function (also known as the root of the equation) is the value of the variable that will result in a value of 0 for the equation. To find the zero of the function, we need to set the equation equal to 0 and solve for the value of x. When we set y=0, we get 3x+12=0, which can be solved to get x=-4.

write the slope intercept form of the equation of the line described.
through: (5, 0) perp to y= -5/3x
The slope-intercept form of the equation of the line through (5, 0) and perpendicular to y = -5/3x is y = 3/5x - 3.
What is the slope-intercept form of a linear equation, and how can we determine the equation of a line perpendicular to another line?
The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. This form is useful for graphing lines and solving problems involving linear relationships.
To determine the equation of a line perpendicular to another line, we use the fact that the slopes of perpendicular lines are negative reciprocals of each other. In other words, if the slope of one line is m, then the slope of a line perpendicular to it is -1/m.
Calculate the slope-intercept form:
We are given that the line we are looking for passes through the point (5, 0) and is perpendicular to the line y = -5/3x. To find the equation of the line, we need to determine its slope and y-intercept.
The slope of the given line is -5/3, so the slope of the line perpendicular to it is:
-1/(-5/3) = 3/5
Therefore, the slope of the line we are looking for is 3/5.
Next, we can use the point-slope form of the equation of a line to find the equation of the line:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is a point on the line. We can substitute m = 3/5 and (x1, y1) = (5, 0) to get:
y - 0 = 3/5(x - 5)
Simplifying this equation, we get:
y = 3/5x - 3
which is the slope-intercept form of the equation of the line we were looking for.
Therefore, the slope-intercept form of the equation of the line through (5, 0) and perpendicular to y = -5/3x is y = 3/5x - 3.

The length of a radius of a circle, measured in feet, is represented by the expression z + 3.6. The diameter of the circle is 11 4/5 ft.
What is the value of z?
Enter your answer as a decimal or mixed number in simplest form in the box.
Answer:
Step-by-step explanation:
The diameter of the circle is twice the length of the radius, so we can write:
2r = d
where r is the radius and d is the diameter.
Substituting the given diameter of 11 4/5 ft, we get:
2r = 11 4/5 ft
To find the length of the radius, we can divide both sides by 2:
r = (11 4/5) / 2
r = 5 9/10 ft
We also know that the length of the radius is z + 3.6, so we can set up the equation:
z + 3.6 = 5 9/10
Subtracting 3.6 from both sides, we get:
z = 5 9/10 - 3.6
z = 2 3/10
Therefore, the value of z is 2 3/10 or 2.3 as a decimal.

A survey of 520 adults aged 18-24 year olds was conducted in which they were asked what they did last Friday night. It found:
172 watched TV
156 ate pizza
38 watched TV and ate pizza, but did not hang out with friends
36 watched TV and hung out with friends, but did not eat pizza
40 hung out with friends and ate pizza, but did not watch TV
38 watched TV, hung out with friends, and ate pizza
63 did not do any of these three activities
How may 18-24 year olds (of these three activities) only hung out with friends last Friday night?
Your Answer:
To find out how many 18-24 year olds only hung out with friends last Friday night, we need to subtract the number of people who engaged in other combinations of activities from the total number of people surveyed:
Total surveyed = 520
Watched TV only = 172 - 38 - 36 - 38 = 60
Ate pizza only = 156 - 38 - 36 - 40 = 42
Watched TV and ate pizza = 38
Did not do any of these three activities = 63
Therefore, the number of 18-24 year olds who only hung out with friends last Friday night can be calculated as follows:
Only hung out with friends = Total surveyed - (Watched TV only + Ate pizza only + Watched TV and ate pizza + Did not do any of these three activities)
Only hung out with friends = 520 - (60 + 42 + 38 + 63)
Only hung out with friends = 217
Therefore, 217 out of the 520 18-24 year olds surveyed only hung out with friends last Friday night.find the measure of gpy

What is equation?In a math equation, two assertions are connected by the equals sign (=), which denotes equivalence. A mathematical assertion used in algebraic equations establishes the equivalence of two mathematical statements. For instance, in the equation 3x + 5 = 14, the equal sign creates a space between the values 3x + 5 and 14. To comprehend the relationship between the two sentences written on opposing sides of a letter, utilise a mathematical formula. The logo and the specific programme typically correspond. An illustration would be 2x - 4 = 2.
The five positive integers will be denoted as a, b, c, d, and e.
We know that c must equal 5, since the median is 5.
The three integers we now have add up to 15 (a + b + c = 15).
We may write the equation as follows since the mean is 5:
(a + b + c + d + e)/5 = 5
a + b + 18 = 25
a + b = 7
a = 1, b = 6, c = 5, d = 8, e = 8
a = 2, b = 5, c = 5, d = 8, e = 8
a = 3, b = 4, c = 5, d = 8, e = 8
Range = 8 - 1 = 7
Range = 8 - 2 = 6
Range = 8 - 3 = 5
So, depending on the precise choice of five positive numbers, the data range might be 5, 6, or 7.

1. The decrease in the balance would be $11.25 2. The interest on the average daily balance would be $28.77. 3. The total interest paid would be $214,960. 4. The payment would be $1,978.
Describe Interest?Interest refers to the amount of money that is charged or earned for the use of borrowed money. It is a fee paid by a borrower to a lender for the use of funds, or a payment received by a depositor from a bank for the use of their money.
Interest rates are typically expressed as a percentage of the principal amount and can be fixed or variable, depending on the terms of the loan or investment. The interest rate charged on a loan is determined by a number of factors, including the creditworthiness of the borrower, the length of the loan, and prevailing market conditions.
1. The decrease in the balance would be $11.25.
Calculation:
Minimum payment = 2.5% of $450 = $11.25
New balance after paying the minimum = $450 - $11.25 = $438.75
The decrease in the balance would be $450 - $438.75 = $11.25.
2. The interest on the average daily balance would be $28.77.
Calculation:
The balance for the first 14 days of the month = $2000
The balance for the last 16 days of the month = $1400
Average daily balance = (14 * 2000 + 16 * 1400) / 30 = $1666.67
Interest for the month = 0.23 / 12 * $1666.67 = $28.77
3. The total interest paid would be $214,960.
Calculation:
No. of payments = 30 * 12 = 360
Total amount paid = $876 * 360 = $315,360
Total interest paid = $315,360 - $125,000 = $190,360
4. The payment would be $1,978.
Calculation:
Monthly interest rate = 7.3% / 12 = 0.6083%
Number of payments = 30 * 12 = 360
Payment = $275,000 * 0.006083 / (1 - (1 + 0.006083)^-360) = $1,977.54 (rounded to nearest dollar: $1,978)

The area of the shaded region in factored form is 9x^2(9 - 4π)
How to find the area of the shaded region in factored formFrom the question, we have the following parameters that can be used in our computation:
Square length = 9x
Radius of circle = 6x
The area of the square is given by (side length)^2.

Area 1 = (9x)^2 = 81x^2
For the circle, we have
Area 2 = π(6x)^2
Area 2 = 36πx^2
The area of the shaded region is the area of the original square minus the area of the circle, which is:
Shaded = 81x^2 - 36πx^2

Find the sum of the following arithmetic series:
Answer:
19107
Step-by-step explanation:
First, we need to find the common difference (d), which we can find by subtracting two consecutive terms. Thus, we can do d = 1 - (-3) = 4.
Now, we need to know how many terms are in the arithmetic series. We can find the number using nth term formula, which is
[tex]a_{n}=a_{1}+(n-1)*d[/tex], where a1 is the first term, n is the term position (e.g., 1st, 2nd).
Although we don't know the term position of 389, we can still plug it into the formula and solving for n will reveal it's term number and the total number of sums in the sequence:
[tex]389=-3+(n-1)*4\\392=(n-1)*4\\392=4n-4\\396=4n\\99=n[/tex]
Now, we can find the sum using the sum formula, which is
[tex]S_{n}=n/2*(a_{1}+a_{n})[/tex]
Sn can become S99 since there are 99 terms and we can let an = a99, which we know is 389.
Now, we must solve for S99:
[tex]S_{99}=\frac{99}{2}*(-3+389)\\ S_{99}=\frac{99}{2}*(386)\\ S_{99}=19107[/tex]
Use implicit differentiation to find an equation of the tangent line to the curve at the given point.
x2+y2=(2x2+2y2−x)2,(0,1/2)
As a result, y = -x + 1/2 is the equatiοn οf the tangent line tο the curve x² + y² = (2x² + 2y² - x)² at the pοsitiοn (0,1/2).
What is equatiοn?An equatiοn in mathematics is a claim that twο mathematical expressiοns are equivalent. An equatiοn has an equal sign, typically has οne οr mοre factοrs, and can be sοlved fοr by applying algebraic οr numerical techniques. Equatiοns are used tο represent real-wοrld phenοmena, resοlve issues, and make predictiοns in many branches οf mathematics, science, and engineering.
given:
We must first use implicit differentiatiοn tο determine the derivative οf the curve in οrder tο determine the equatiοn οf the tangent line tο the curve at the pοsitiοn (0,1/2).
By taking the derivative οf the equatiοn's twο sides with regard tο x, we arrive at:
dy/dx = 2x + 2y
(2x² + 2y²- x) * (4x - 1) (4x - 1)
When we sοlve fοr dy/dx and simplify this equatiοn, we get:
[(1 - 4x)(2x + 2y)] Equals dy/dx / [4(2x² + 2y² - x) - 2y(1 - 4x)]
The slοpe οf the tangent line at the pοint (0,1/2) can nοw be calculated by plugging in the numbers x = 0 and y = 1/2:
dy/dx = [(1 - 4(0))
(2(0) + 2(1/2))] / [4(2(0)² + 2(1/2)² - 0) - 2(1/2)(1 - 4(0))] = -1
Therefοre, the tangent line's slοpe at the pοsitiοn (0,1/2) is negative οne. We can use the pοint-slοpe fοrm οf a line tο determine the equatiοn οf the tangent line:
where (x1,y1) is the tangency pοint and m is the inclinatiοn οf the tangent line. When we enter the numbers we have, we οbtain:
y - 1/2 = -1(x - 0) (x - 0)
When we simplify this sοlutiοn, we οbtain:
y = -x + 1/2
As a result, y = -x + 1/2 is the equatiοn οf the tangent line tο the curve x² + y2 = (2x² + 2y² - x)² at the pοsitiοn (0,1/2).

Jake gets to a party at to'dock having alredy baned off 25 calories throughout his normal day. After dancing at the party. he checked! and burned off 85 total for the day by 9o'clock.
The calories burned per hour is 30 calories per hour
How to determine the calories burned per hourFrom the question, we have the following parameters that can be used in our computation:
Calories at 7 = 25 calories
Calories at 9 = 85 calories
Using the above as a guide, we have the following:
Rate = Difference in calories/Difference in time
Substitute the known values in the above equation, so, we have the following representation
Rate = (85 - 25)/(9 - 7)
Evaluate
Rate = 30
Hence, the rate is 30 calories per hour

Mr. Gaspar wants to store a 12-foot-long pipe
in a tool closet. The closet has the shape of a
right rectangular prism with the dimensions
shown. Will the pipe fit? Show your work.
The longest pipe can fit in the prism is 11.7 ft, so, 12 ft long pipe does not fit.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
From the given figure,
By considering base of the prism, we get
c²=6²+6²
c²=72
c=6√2 ft
Now, d²=c²+8²
d²=72+64
d²=136
d=√136
d= 11.7 ft
Hence, the longest pipe can fit in the prism is 11.7 ft, so, 12 ft long pipe does not fit.

Emails arrive randomly on Oliver's computer at an average rate of 1.46 per hour. Stating a necessary assumption, find the probability that between 9.00am and 11.30am Oliver receives: (i) no emails
The probability that Oliver will receive no emails in between 9.00am and 11.30am is 2.599%.
What is Poisson Distribution?Poisson Distribution is defined as a discrete distribution which measures the likelihood of happening an event in a certain period of time.
The formula for Poisson distribution is,
P(x) = (e^(-λ) λˣ) / x!
Given that,
Average rate of arrival of emails in an hour = 1.46 per hour
Between 9.00 am and 11.30 am, there are 2.5 hours.
Average rate of arrival of emails in 2.5 hours = 2.5 × 1.46
= 3.65
So, λ = 3.65
x = 0 (since no emails.)
P(0) = (e^(-3.65) (3.65)⁰) / 0!
= e^(-3.65)
= 0.02599
= 2.599%
Hence the probability is 2.599%.

Jack has 7 yards of rope. He wants to cut it into pieces of different sizes. Jacks needs 84 inches of rope to tie some packages and 4 feet of rope for another project. Does Jack have enough rope? Explain.
Jack has enough rope for both projects.
What is multiplication?Multiplication is a type of mathematical operation. The repetition of the same expression types is another aspect of the practice.
For instance, the expression 2 x 3 indicates that 3 has been multiplied by two.
Given:
Jack has 7 yards of rope.
He wants to cut it into pieces of different sizes.
Jack needs 84 inches of rope to tie some packages and 4 feet of rope for another project.
First, we need to convert all the measurements to the same units.
Let's convert yards to inches and feet to inches:
7 yards = 21 feet = 252 inches
4 feet = 48 inches
Now, let's add up the lengths of rope that Jack needs:
84 inches + 48 inches = 132 inches
So Jack needs a total of 132 inches of rope.
Since 132 inches is less than the total length of rope that Jack has (252 inches).
Therefore, he does have enough rope for both projects.
