Suppose that the manufacturer of a gas clothes dryer has found that when the unit price is p dollars, the revenue R in dollars is
R(p)= -4p^2+4000p
What unit price should be established for the dryer to maximize revenue?
What is the maximum revenue?
Answer:
p=$500 is the unit price to get maximum revenue
Maximum revenue = $1,000,000
Step-by-step explanation:
the revenue R in dollars is:
[tex]R(p)= -4p^2+4000p[/tex]
To find out the unit price to get maximum revenue we find out the vertex
In the given quadratic equation a=-4 and b= 4000
Formula to find out the x coordinate of vertex is
[tex]x=\frac{-b}{2a}[/tex], plug in the values
[tex]x=\frac{-4000}{2(-4)}[/tex]
x=500
So p=$500 is the unit price to get maximum revenue
Now we find the maximum revenue . Plug in 500 for p in the given equation
[tex]R(p)= -4p^2+4000p[/tex]
[tex]R(500)= -4(500)^2+4000(500)[/tex]
R(500)=1000000
Maximum revenue = $1,000,000
The area of a circle is 113.04 inches squared. What is the radius of the circle?
A. 36 inches
B. 18 inches
C. 12 inches
D. 6 inches
Answer
The Answer to your question in 6
Step-by-step explanation:
The formula to find the area is
r^2 * pi = area
we know that the area is 113.04 and pi = 3.14
so
x^2 * 3.14 = 113.04
divide both sides by 3.14
x^2 = 36
now for the final step we need to find the root of both sides
√x^2 = √36
x = 6
so the radius is 6.

The probability of reaching into a drawer without looking and selecting a black sock is 5/6. If there are a total of 24 socks in the drawer, how many socks in the draw are black? Please help me :c
The probability of selecting a black sock is 5/6 and there are 24 socks in total. By setting up and solving a simple equation, we find that there are 20 black socks in the drawer.
Explanation:This question is about the concept of probability in mathematics. The probability of an event occurring is calculated by the number of desired outcomes divided by the total number of possible outcomes. In this case, we are given that the probability of reaching into a drawer without looking and magically pulling out a black sock is 5/6. With a total of 24 socks in the drawer, to figure out how many socks are black, we can set up a simple equation where x represents the number of black socks. Thus, x/24 = 5/6. Solving this equation, we get x = (5/6) * 24, which simplifies to x = 20. So, there are 20 black socks in the drawer. That's indeed a lot of black socks!

Write the ordered pairs that represent the location of Sam and the theater
The question seems to require using ordered pairs to locate Sam and the theater, but lacks the specific coordinates or context needed for a precise answer. Ordered pairs are essential in geometry for representing positions.
Explanation:The question seems to pertain to locating positions or objects using ordered pairs, which falls under the domain of algebra and geometry in mathematics. An ordered pair (x, y) is used to define the positions on a plane, with 'x' representing the horizontal component and 'y' representing the vertical component.
Unfortunately, the question lacks specific information about the coordinates of Sam and the theater, making it impossible to provide exact ordered pairs without additional context. In scenarios involving maps or spatial planning such as finding locations in a city or arranging objects with a spatial relation to each other, ordered pairs serve as a crucial means of representation.
Exercises involving ordered pairs deepen understanding of coordinate systems, which are fundamental in geometry and crucial for various applications in science and engineering.

For a single roll of two dice, are rolling a sum of 6 and rolling doubles mutually exclusive events?
Answer: They are not mutually exclusive events.
Step-by-step explanation:
Let A be the event of getting a sum of 6 on dice.
Let B be the events of getting doubles .
A={ (1,5), (2,4), (3,3), (4,2), (5,1) }
B = { (1,1) , (2,2), (3,3), (4,4), (5,5), (6,6) }
Since we know that Mutaullty exclusive events are those when there is no common event between two events.
i.e. there is empty set of intersection.
But we can see that there is one element which is common i.e. (3,3).
So, n(A∩B) = 1 ≠ ∅
Hence, they are not mutually exclusive events.
Answer:
They are not mutually exclusive events.

(b) Suppose a car is traveling southwest on King Avenue and turns left onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.
(c) Suppose a car is traveling northeast on King Avenue and turns right onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.
Answer:
the guy is right except number 2
Step-by-step explanation:
if the car turns left that means it went west and since 4th and 3rd street are parallel and King Ave. is a transparent then street 4 and 3 have the same angles. y is 75 and a vertical that means the car makes a 75 degrees angles .

a geometric sequence has an initial value of 25 and a common ratio of 1.8. Write a function to represent this sequence . Find.the 23rd term.
23rd term of the given geometrical sequence is [tex]a_{23} = 25(1.8)^{22}[/tex].
Function to represent sequence is [tex]25,25(1.8), 25(1.8)^{2} , 25 (1.8)^{3} , ....... ,25(1.8)^{n}[/tex]
What is geometric sequence?" Geometric sequence is defined as the sequence whose ratio of the consecutive terms is always constant."
Formula used
nth term of the geometric sequence
[tex]a_{n} = a r^{n-1}[/tex]
a = first term
r = common ratio
[tex]a_{n}[/tex] = nth term
According to the question,
First term of the geometric sequence 'a' = 25
Common ratio of the geometric sequence 'r' = 1.8
Substitute the value in the formula to get 23rd term,
[tex]a_{23} = 25(1.8)^{23-1}[/tex]
⇒[tex]a_{23} = 25(1.8)^{22}[/tex]
Function to represent this sequence
[tex]a, a(r),a(r)^{2} , a (r)^{3} , ....... ,a(r)^{n}[/tex]
= [tex]25,25(1.8), 25(1.8)^{2} , 25 (1.8)^{3} , ....... ,25(1.8)^{n}[/tex]
Hence, 23rd term of the given geometrical sequence is [tex]a_{23} = 25(1.8)^{22}[/tex].

The area of the pool is the amount of space on it.
The area of the pool is 684 square feet
The dimensions of the pool are:
10ft by 20ft, 8ft by 20ft and 27ft by 12ft
The area of the pool is then calculated as:
A = 10 * 20 + 8 * 20 + 27 * 12
Evaluate the products
A = 200 + 160 + 324
Evaluate the sums

A square has side lengths of 7 inches. Find the length of the square’s diagonal.
Final answer:
The length of the square's diagonal with side lengths of 7 inches is found using the Pythagorean theorem, leading to a diagonal of approximately 9.899 inches.
Explanation:
To find the length of the square's diagonal when the side lengths are 7 inches, we can use the Pythagorean theorem. The diagonal of a square creates two right triangles, with the diagonal being the hypotenuse. You can think of this as half of the square divided along the diagonal. Each of these triangles has two legs that are each equal to the side of the square and a hypotenuse which is the diagonal we want to find.
The formula for the Pythagorean theorem is a² + b² = c², where a and b are the legs of the right triangle, and c is the hypotenuse. Since the legs are both 7 inches (the side length of the square), we have:
7² + 7² = c²
49 + 49 = c²
98 = c²
This simplifies to:
c = √98
c ≈ 9.899 inches (rounded to three decimal places)
Therefore, the diagonal of the square is approximately 9.899 inches long.
