Answer:
To find the total number of shirts that would make the total cost for each company the same, we can set the two equations equal to each other and solve for the number of shirts:
Red Nose: t = 3.50r + 79
Green Machine: t = 5r + 40
3.50r + 79 = 5r + 40
Subtracting 3.50r from both sides, we get:
79 = 1.50r + 40
Subtracting 40 from both sides, we get:
39 = 1.50r
Dividing both sides by 1.50, we get:
r = 26
So the total cost for each company would be the same if 26 shirts are ordered.
To find the total cost for each company when 26 shirts are ordered, we can substitute 26 for r in each equation:
Red Nose: t = 3.50(26) + 79 = $192
Green Machine: t = 5(26) + 40 = $170
Therefore, if 26 shirts are ordered, the total cost would be $192 for Red Nose and $170 for Green Machine.

The Revenue and Cost equations for a company are known to be polynomials of order 1 and 2 respectively. It is also known that the graphs of the two equations meet at points A(1,1) and B(5,9) while the third point of the cost function is C(2,0), obtain the following:
a) The Revenue equation and the cost equation
b) What do the common solutions to the two equations signify?
Answer: a) We know that the Revenue equation is a polynomial of order 1, so we can write it in the form:
R(x) = ax + b
where a and b are constants to be determined. We also know that R(1) = 1 and R(5) = 9, so we have two equations:
a(1) + b = 1
a(5) + b = 9
Solving these equations simultaneously, we get:
a = 2, b = -1
Therefore, the Revenue equation is:
R(x) = 2x - 1
Similarly, the Cost equation is a polynomial of order 2, so we can write it in the form:
C(x) = ax^2 + bx + c
where a, b, and c are constants to be determined. We know that C(1) = R(1) = 1 and C(5) = R(5) = 9, so we have two equations:
a(1)^2 + b(1) + c = 1
a(5)^2 + b(5) + c = 9
We also know that C(2) = 0, so we have a third equation:
a(2)^2 + b(2) + c = 0
Solving these equations simultaneously, we get:
a = 1, b = -4, c = 4
Therefore, the Cost equation is:
C(x) = x^2 - 4x + 4
b) The common solutions to the Revenue and Cost equations represent the production level(s) at which the company makes a profit, since the Revenue equation represents the amount of money the company earns and the Cost equation represents the amount of money the company spends. In other words, the common solutions are the values of x for which R(x) - C(x) > 0. At these production levels, the company's revenue is greater than its cost, resulting in a profit. At production levels where R(x) - C(x) < 0, the company is making a loss. At production levels where R(x) - C(x) = 0, the company is breaking even. Therefore, the common solutions to the two equations signify the production levels at which the company makes a profit or breaks even.

Trump: "Now that's a nice question, folks. That's what I want."
The difference between the cost of Sabina's journey and the cost of Amir's journey is -£38.70.
We have,
The cost of Sabina's journey is £65.25.
Since she gets off the cost of the ticket, her journey is free, so the cost is £0.
Amir's journey consists of two segments:
London to Coventry and Coventry to Telford.
The cost of the London to Coventry ticket is £23.75, and the cost of the Coventry to Telford ticket is £14.95.
Difference = Sabina's Journey Cost - Amir's Journey Cost
Difference = £0 - (£23.75 + £14.95)
Difference = £0 - £38.70
Difference = -£38.70
This means that Amir's journey is £38.70 more expensive than Sabina's journey.
Therefore,
The difference between the cost of Sabina's journey and the cost of Amir's journey is -£38.70.

The correct graph would be the one with a normal distribution curve centered at 0, with two tails shaded on either side, representing the lowest and highest 4% of scores So option C is correct.
What is standard normal distribution ?
The standard normal distribution is a special case of the normal distribution in which the mean is 0 and the standard deviation is 1. It is also known as the "Z-distribution" because the scores are expressed in terms of their z-scores, which are the number of standard deviations above or below the mean.
The standard normal distribution is a bell-shaped curve that is symmetric around the mean of 0. It is used in statistics as a reference distribution for calculating probabilities and making statistical inferences.
To convert a normal distribution with a given mean and standard deviation to a standard normal distribution, we use the formula:
z = (x - μ) / σ
According to the question:
To find the bone density test scores that can be used as cutoff values separating the lowest 4% and highest 4%, we need to find the z-scores that correspond to the 4th and 96th percentiles of the standard normal distribution.
Using a standard normal table, we find that the z-score corresponding to the 4th percentile is approximately -1.75, and the z-score corresponding to the 96th percentile is approximately 1.75.
Therefore, the bone density test scores that can be used as cutoff values separating the lowest 4% and highest 4% are approximately -1.75 and 1.75, respectively.
To sketch the region containing the lowest 4% and highest 4%, we need to shade the area under the normal curve to the left of -1.75 and to the right of 1.75.
The shaded regions represent the lowest 4% and highest 4% of bone density test scores, respectively. The correct graph would be the one with a normal distribution curve centered at 0, with two tails shaded on either side, representing the lowest and highest 4% of scores.

The polynomial function f(x) which produced the graph shown is f(x) = -6(x - 1/2)²(x + 1)²(x - 2).
What is a polynomial graph?In Mathematics and Geometry, a polynomial graph touches the x-axis at zeros, roots, solutions, x-intercepts, and factors with even multiplicities.
By critically observing the graph of the polynomial function shown above, we can logically deduce that its x-intercepts include the following;
x = -1 ⇒ x + 1 = 0.
x = 2 ⇒ x - 2 = 0.
Also, the graph has a zero of multiplicity 2 at x = 1/2;
x = 1/2 ⇒ x - 1/2 = 0.
(x - 1/2)²
In this context, an equation that represent the polynomial function is given by:
f(x) = a(x - 1/2)²(x + 1)²(x - 2)
By evaluating and solving for the leading coefficient "a" in this polynomial function based on the y-intercept (0, 3), we have;
3 = a(0 - 1/2)²(0 + 1)²(0 - 2)
3 = a(1/4)(-2)
3 = -a/2
a = -6.
Therefore, the required polynomial function is given by:
f(x) = -6(x - 1/2)²(x + 1)²(x - 2)

Let the region R be the area enclosed by the function f(x) = ln (x) + 1 and
g(x)=x-1. If the region R is the base of a solid such that each cross section
perpendicular to the a-axis is a semi-circle with diameters extending through the
region R, find the volume of the solid. You may use a calculator and round to the
nearest thousandth.
The volume of the solid is 7.58 thousandths when rounded to the nearest thousandth.
What is area?Area is a measure of the size of a given space or the amount of a given surface. It can be measured in square feet, square meters, acres, hectares, and other units. Area can be used to describe the size of a two-dimensional shape or the surface area of a three-dimensional object. Area can also be used to calculate the amount of material needed to cover a given space, such as for a roof, carpet, or other covering.
To find the volume of the solid, we will use the following formula:
V=∫baπ(y2−(x−1)2)dx
Where b is the upper bound of the integral, a is the lower bound of the integral and y is the height of the solid.
Since the region R is the base of the solid, we can set a = 0 and b = 2, since this is the x-value at which the two functions intersect. Additionally, we can set y = ln(x) + 1 since this is the height of the solid.
Therefore, the volume of the solid is:
V = ∫02π(ln(x)2 + 12 − (x−1)2)dx
Calculating the integral, we get:
V = [π(xln(x)2 + x − 2xln(x) − x + 1)]02
Substituting the bounds of the integral, we get:
V = [π(22ln(2)2 + 2 − 4ln(2) − 2 + 1)] − [π(02ln(0)2 + 0 − 2ln(0) − 0 + 1)]
Simplifying the equation, we get:
V = π(ln(2)2 + 1 − 2ln(2))
Finally, substituting the value of ln(2) into the equation, we get:
V = 3.14159 (2.386294 + 1 − 4.772188) ≈ 7.58 thousandths
Therefore, the volume of the solid is 7.58 thousandths when rounded to the nearest thousandth.
In conclusion, the volume of the solid whose base is the region R and each cross section perpendicular to the a-axis is a semicircle is 7.58 thousandths when rounded to the nearest thousandth. This was calculated by integrating the equation V=∫baπ(y2−(x−1)2)dx with the bounds of integration a=0 and b=2 and the height of the solid y=ln(x)+1.

the area of a rectangle is 14 square units. it has the side length of x and y. given each value for x, find y.
1. x = 4 and 1/5
2. x = 2 and 1/3
3. x = 7/6
Answer:
1. y = 3 1/3
2. y = 6
3. y = 12
Step-by-step explanation:
A = xy => xy = 14 => y = 14/x
1. x = 4 1/5 = 21/5
y = 14/x = 14/(21/5) = (5 x 14)/21 = 10/3 = 3 1/3
2. x = 2 1/3 = 7/3
y = 14/x = 14/(7/3) = (3 x 14)/7 = 6
3. x = 7/6
y = 14/x = 14/(7/6) = (6 x 14)/7 = 12
Derrick invested some money at 2.25% simple interest and $1000 less than twice this amount at 1.5%. His total income from the interest was $510. How much was invested at each rate?
Derrick invested $23,306.28 at 2.25% and $462.79 at 1.5%.
What is percentage?
Percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol "%". For example, 50% means 50 out of 100 or 0.5 as a decimal.
Let's start by assigning variables to the unknown quantities in the problem. Let x be the amount Derrick invested at 2.25% and y be the amount he invested at 1.5%.
According to the problem, Derrick invested "1000 less than twice" the amount he invested at 2.25% at 1.5%. This means:
y = 2(0.0225x - 1000) = 0.045x - 2000
Now we can set up an equation based on the total income from the interest:
0.0225x + 0.015y = 510
Substituting the expression for y from the first equation, we get:
0.0225x + 0.015(0.045x - 2000) = 510
Simplifying and solving for x, we get:
0.0225x + 0.000675x - 30 = 510
0.023175x = 540
x = 23306.28
So Derrick invested approximately $23,306.28 at 2.25%. To find the amount he invested at 1.5%, we can substitute this value for x in the equation for y:
y = 0.045x - 2000 = 0.045(23306.28) - 2000 = 462.7856
So Derrick invested approximately $462.79 at 1.5%.
Therefore, Derrick invested $23,306.28 at 2.25% and $462.79 at 1.5%.

What exactly does the word interest mean?Divide the sum by the funding cost, the remaining time, and other factors to determine the simple interest rate. Principal loan repayment hours is the marketing plan with the simplest return. The simplest way to determine involvement is through this technique. In most instances, income is calculated as a percentage of the starting sum.
Here,
Part A: To start, we must divide the yearly interest rate by 12 to determine the monthly interest rate:
Monthly interest rate equals 24.90% divided by 12 equals 0.0249 per month.
=> Monthly payment = (P * r) / (1 - (1 + r)⁻ⁿ
=> Monthly payment = $104.23 per month
=> (2784 * 0.0249 / (1 - (1 + 0.0249)(-36)).
Taking the entire number of months (36) into account, we get:
Cost of the whole deal 1 = 36 * $104.23 = $3,751.28
As a result, offer 1's overall price is $3,751.28.
Part B:
First, we figure out the interest rate per month:
Monthly interest rate = 22.90% / 12 = 0.0229 / month.
=> Monthly payment = (P * r) / (1 - (1 + r)⁻ⁿ
=> Monthly payout
=> (1 - (1 + 0.0229)(-48)) / (2784 * 0.0229) ≈ $82.12/month
Using the entire number of months (48) as a multiplier, we obtain:
Cost of the whole deal 2 = 48 * $82.12 = $3,938.56
Part C:
Offer 1 costs $3,751.28 in total, while Offer 2 costs $3,938.56 in total.
Offer 1 should be selected by the new homeowner since it has a reduced overall cost.

As a result, Ava's luggage will weigh 123622200 grams more than the permitted maximum.
What exactly is weight?Weight is the force of gravity that pulls objects toward the core of the Earth. The resulting force that pulls a substance toward Earth is known as gravity. In contrast to gravity force, which occurs among any two masses, this only occurs between Earth as well as a mass.
First, we need to convert all the weights to grams, since the weight limit is given in kilograms and the weights of clothes, electrical accessories, and toiletries are given in grams.
Maximum weight limit = 2020 kg = 2020000 g
Weight of empty suitcase = 33 kg = 33000 g
Weight of clothes = 55 kg = 55000 g
Weight of electrical accessories = 44 kg = 44000 g
Weight of 55 hardback books = 55 x 720720 g = 39639600 g
Weight of toiletries = 46004600 g
Total weight of suitcase and contents = 33000 + 55000 + 44000 + 39639600 + 46004600 = 125642200 g
Amount over maximum weight limit = total weight - maximum weight limit = 125642200 - 2020000 = 123622200 g

The function F(x) = x^2 represents a quadratic function, where the input value (x) is squared to produce the output value (F(x)).
To find the value of F(2), we simply need to substitute 2 in place of x in the equation:
F(2) = (2)^2 = 4
This means that when we input the value 2 into the function, it will output the value 4.
In other words, F(2) represents the value of the quadratic function at the point where x is equal to 2.

If F(x)=x^2 then what is f(2).
Dan is training for a bike race. He wants to bike 300 miles over the next couples of weeks. Dan biked 29 miles a day for 3 days. Then, he biked 32 miles a day for 4 days. How many more miles does he still have to bike to get to his goal of 300 miles?
A. Sara estimated that Dan would need to bike about 80 more miles to get to his goal of 300 miles. Is this a reasonable estimate? Why or why not?
B. Write an equation for this problem with a letter standing for the unknown quantity.
C. Solve the problem. Show your work.
Answer:
Step-by-step explanation:
a. Sara's estimate is reasonable because:
Dan has biked for 7 days so far, 29 miles for 3 days and 32 miles for 4 days.
If you round 29 and 32 up and down respectively to 30, then Dan will of have ridden about 30 * 7, or 120 miles so far. 300-120 is 80, so that is a good estimate.
b. If x stands for the miles Dan still needs to bike, then:
(29*3) + (32*4) + x = 300
c. 87 + 128 + x = 300
x = 85
