Using a System to Break Even
A company’s weekly revenue, in thousands, is modeled by the equation R = -p2 + 14p, where p is the price of the product it makes. The company is considering hiring an outside source to distribute its products, which will cost the company 4p + 24 thousand dollars per week.
Part B
Create a system of equations for the break-even point(s) of the company’s product to assist with the decision of hiring the distributor. Assume the distributor’s cost is the only cost that needs to be considered.
Answer: P^2 - 10p + 24 = 0
Step-by-step explanation:
Given that a company’s weekly revenue, in thousands, is modeled by the equation
R = -p2 + 14p,
where p is the price of the product it makes. The company is considering hiring an outside source to distribute its products, which will cost the company 4p + 24 thousand dollars per week.
If the company want to break even, the cost of hiring distributors will be equal to the revenue per week.
Therefore,
-P^2 + 14p = 4p + 24
Collect the like terms
-P^2 + 14p - 4p - 24 = 0
-P^2 + 10p - 24 = 0
Multiply all by minus sign
P^2 - 10p + 24 = 0

In your own words, what does it mean when something has an extrinsic value? What is an
example of an item having extrinsic value?
Answer using complete sentences.
Answer:
Extrinsic value means to have the motivation or desire to do something by yourself. To have the motivation to complete a task or goal without outside help.
Step-by-step explanation:
One way of having extrinsic value is that you go to school and you want to go to Germany. Your school fortunately has a student exchange program, so you apply hoping that you get in.
Now you go home, you get the best grades so people recognize you. You teach yourself German and you do all the things that you need to do in order to go.
What makes this extrinsic is that no one forced you to go, you did all this work by will. Your own motivation.

Hey there!
We have the absolute value of x is greater than two.
Thus, to solve absolute value inequalities, we want to break the inequality down.
We break this down to
x>2
x<-2
Thus, we don't need to simplify this any further, and have our answer.
Hope this helps :)
Answer:
x >= 2 or x <= -2
Step-by-step explanation:
|x|>= 2
Means the absolute value of x is greater than or equal to two.
When we deal with absolute value, we can equivalently break into two cases
+x >= 2 => x >= 2
-x >= 2 => x <= -2
On the number line it looks like what is shown in the attached figure.
Find an equation of variation where y varies jointly as x and the square of z, and where y=70, when x=21 and z=5.
Answer:
[tex]y = 181.75xz^2[/tex]
Step-by-step explanation:
Given
y jointly varies to x and z^2
Required
Find the equation
We start by writing out the variation;
[tex]y\ \alpha\ xz^2[/tex]
Write as equation
[tex]y = kxz^2[/tex]
Substitute values of x,y and z
[tex]70 = k * 21 * 25^2[/tex]
[tex]70 = k * 21 * 25 * 25[/tex]
[tex]70 = k * 13125[/tex]
Divide both sides by 7
[tex]\frac{70}{13125} = \frac{k * 131251}{13125}[/tex]
[tex]\frac{70}{13125} = k[/tex]
[tex]187.5 = k[/tex]
[tex]k = 181.75[/tex]
Substitute k in [tex]y = kxz^2[/tex]
[tex]y = 181.75xz^2[/tex]
Liam is making chocolate chip cookies. The recipe calls for 1 cup of sugar for every 3 cups of flour. Liam only has 2 cups of flour.
How much sugar should Liam use?
Explain why your answer is correct.
Answer:
2/3 cups of sugar
Step-by-step explanation:
Answer:
2/3 cups of sugar
Step-by-step explanation:
If 3 cups of flour: 1 cup of sugar
2 cups of flour: x cup of sugar
Cross multiply
3x = 2 × 1
3 3
x = 2/3
My answer is correct because every 3 cups of flour is a full cup (1) but because he has 2 cups of flour, the cup of sugar is going to be less than 1 because 3 cups of flour is bigger than 2 cups of flour.
Under what conditions are we allowed to add or subtract radicals together?
Answer/Step-by-step explanation:
The conditions where we are allowed to subtract or add radicals together is when the radicands, which is the number inside the radical, of both radicals are the same. And also, when they both have the same indices, that is, for example, they have the same root.
Take for example the following radical expression:
[tex]4\sqrt{2} + 3\sqrt{2}[/tex]
Both radicals, [tex]4\sqrt{2} and 3\sqrt{2}[/tex], have the same radicand, [tex]\sqrt{2}[/tex] , and also the same index of square root.
Therefore, they are regarded as like terms, and can be added or subtracted together.
Thus,
[tex]4\sqrt{2} + 3\sqrt{2} = 7\sqrt{2}[/tex]

If y varies jointly with x and z and y=40 when x=10 and z=9 find z when x =55 and y=105
Answer:
z = 189/44
Step-by-step explanation:
The "varies jointly" relationship can be expressed by ...
y = kxz
We can find k from the given values.
40 = k(10)(9)
40/90 = k = 4/9 . . . divide by the coefficient of k
Now we want to find z for given values of x and y. That can be found from ...
y = (4/9)xz
9y/(4x) = z . . . . . multiply by 9/(4x)
Filling in the new numbers, we have ...
z = 9·105/(4·55)
z = 4 13/44 = 189/44 ≈ 4.2954...(repeating 54)

Guess the rule and write down the missing number: 1 5 6 11 _ 28
Answer:
1 5 6 11 17 28
Step-by-step explanation:
Hi there! :)
Answer:
17 is the missing number.
Step-by-step explanation:
The rule is to add the previous two numbers together to get the next number. For example:
1 + 5 = 6
5 + 6 = 11
Using this rule to solve for the missing number gets us:
6 + 11 = 17
We can check this work as well:
11 + 17 = 28.
Therefore, 17 is the missing number.

The equivalent statement for the given statement - It is not the case that a gun and a nose are both weapons is A gun is not a weapon or a nose is not a weapon.
What is De Morgan's Law?The De Morgan's law states that → ~(p ∧ q) is same as (~ p ∨ ~ q). Theoretically, we can write it as → Not (A and B) is the same as Not A or Not B.
Given is the following statement - It is not the case that a gun and a nose are both weapons.
Now, we know that the De Morgan's law states that → Not (A and B) is the same as Not A or Not B. In the statement given -
A = gun
B = nose
~(p ∧ q) = Not(A ∧ B)
So, we can write it as -
~(p ∧ q) = Not(A ∧ B) = A gun is not a weapon or a nose is not a weapon.
where -
A gun is not a weapon → ~p
or → ∨
a nose is not a weapon → ~q
Therefore, the equivalent statement for the given statement - It is not the case that a gun and a nose are both weapons is A gun is not a weapon or a nose is not a weapon.

What is the length of the diagonal of a TV that measures 2.25 feet high and 4 feet wide?
Answer: Rounded, the diagonal is 4.6 feet
Step-by-step explanation: Use the Pythagorean Theorem: c² = a² + b²
Then take the square root of c² to find the length
2.25² =5.0625 This is a²
4² = 16 This is b² Add a² + b² to get c²
5.o625 + 16 = 21.0625 This is c²
√21.0625 = 4.589389938 This is the square root.
Round this to common measurements or "significant digits" 4.6 feet.

What is the value of the expression iºxi1xi2 xj3 xi4?
Answer:
The value of the given expression is - 1
Step-by-step explanation:
I believe you meant this expression to be iº [tex]*[/tex] i¹ [tex]*[/tex] i² [tex]*[/tex] i³ [tex]*[/tex] i⁴. If that is so, then we can assume that i = imaginary number, and solve for the value of the expression.
Anything taken to the power of 0 is 1, therefore we can simplify the expression as such,
1 [tex]*[/tex] i¹ [tex]*[/tex] i² [tex]*[/tex] i³ [tex]*[/tex] i⁴ ... at the same time anything taken to the power of one, is simply the base value, so -
1 [tex]*[/tex] i [tex]*[/tex] i² [tex]*[/tex] i³ [tex]*[/tex] i⁴ ... we know that multiplying values of like bases can be combined by adding their exponents, so let's apply that rule -
1 [tex]*[/tex] i¹⁰ ... let's break i¹⁰ into ( i² )⁵. i² is, in other words, - 1 applying the imaginary number rule. Respectively ( - 1 )⁵ = - 1, our solution.
Claire is cycling at a speed of 12 miles per hour. Han is cycling at a speed of 8 miles per hour. If they start at the same position, chosen at zero, and bike in straight opposite directions, what will the distance between them be after 45 minutes?
Answer:
45 minutes is 3/4 of an hour, so find 3/4 of 12.
Divide 12 by 4 to get 1/4 of 12. That is 3.
3/4 is 3 of those, so multiply it by 3 to get 9.
So, she will have biked 9 miles.
Answer:
180 miles.
Step-by-step explanation:
First, we have to find out how far Claire is after 45 minutes:
12 x 45 = 540
Now, we need to find out how far Han is after 45 minutes:
8 x 45 = 360
Lastly, we need to subtract how far Claire went by how far Han went:
540 - 360 = 180
Final answer:
The distance between Claire and Han after 45 minutes will be 180 miles.

Please solve for x and y. If you do, also write the steps you used.
Answer: a = 8, x = 56, y = 68
Step-by-step explanation:
Was there a description that stated this was a parallelogram?
Since that information was not provided....
I used the Law of Cosines to find x = 56°.
Congruent sides implies congruent angles so Center-Q-R = 56°.
Triangle Sum Theorem results in y = 68°
Vertical angles results in S-Center-P = 68°
Triangle sum Theorem results in S-P-Center = 68°
Now we can see that alternate interior angles are congruent, therefore PQRS is a parallelogram. Diagonals are bisected at the intersection so a = 8

Richie and his brother have a paper route. Together they can deliver all of the papers in 40 minutes, and Richie can do it alone in 90 minutes. Richie’s brother slept in one day, leaving Richie to deliver alone for 30 minutes. How long must the two of them work together to finish delivering the newspapers?
Answer
30 minutes
Step-by-step explanation:
Answer: approximately 26.66667 minutes
This converts to 26 minutes, 40 seconds
=================================================
Explanation:
Let's say there are 360 newspapers that need to be delivered.
The two brothers can get the job done in 40 minutes if they work together. Their rate is 360/40 = 9 newspapers per minute.
Richie can do the full job alone in 90 minutes. So his rate would be 360/90 = 4 newspapers per minute. In 30 minutes, he delivers 30*4 = 120 newspapers. This leaves 360 - 120 = 240 left over.
Divide this over the rate of 9 papers per minute to get 240/9 = 26.66667 approximately. It takes about 26.66667 minutes to finish up delivering the 240 remaining newspapers if the brothers work together.
The portion 0.66667 multiplies with 60 to get 0.66667*60 = 40.0002 which rounds to 40 (we have rounding error going on). This means
26.66667 minutes = 26 minutes, 40 seconds
