A baseball team plays in a stadium that holds 52,000 spectators. With ticket prices at $10, the average attendance had been 5,000. When ticket prices were lowered to $8, the average attendance rose to 15,000. (a) Find the demand function (price p as a function of attendance x), assuming it to be linear.
Answers
Answer:
p = (-1/5000)x +11
Step-by-step explanation:
We are given two points (x, p) as (5000, 10) and (15000, 8). Using the two-point form of the equation of a line, we can find the equation to be ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . . 2-point form
p = (8 -10)/(15000 -5000)(x -5000) +10
p = -2/10000(x -5000) +10
p = -x/5000 +11 . . . . . linear demand function
Final answer:
A student asked how to find the demand function for a baseball team's ticket prices based on attendance. By finding the slope between two given points and using the point-slope form, the demand function is determined to be p = $11 - 0.0002x.
Explanation:
To find the demand function that relates the price p of baseball tickets to the average attendance x, we can use the two given points (x, p) = (5,000, $10) and (15,000, $8) and assume the relationship is linear. We can express the demand function as p = mx + b, where m is the slope and b is the y-intercept.
First, find the slope m:
m = (p2 - p1) / (x2 - x1)
m = ($8 - $10) / (15,000 - 5,000)
m = -$2 / 10,000 = -0.0002
Next, we'll use the slope and one of the points to find b, the y-intercept. Plugging into the point-slope form:
p - p1 = m(x - x1)
$10 - p = -0.0002(5,000 - x)
$10 - p = -1 + 0.0002x
p = $11 - 0.0002x
The demand function is p = $11 - 0.0002x.
Write an equation for an ellipse centered at the origin, which has foci at (\pm8,0)(±8,0)left parenthesis, plus minus, 8, comma, 0, right parenthesis and vertices at (\pm17,0)(±17,0)left parenthesis, plus minus, 17, comma, 0, right parenthesis
Answers
Answer:
The equation of the ellipse is [tex]\frac{x^{2}}{(17)^{2}}+\frac{y^{2}}{(15)^{2}}=1[/tex]
Step-by-step explanation:
The standard form of the equation of an ellipse with center (0 , 0) is
[tex]\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1[/tex] , where
The coordinates of the vertices are (± a , 0) The coordinates of the foci are (± c , 0) , where c ² = a² - b²∵ The ellipse is centered at the origin
∴ The center of it is (0 , 0)
∵ It has foci at (± 8 , 0)
- The coordinates of the foci are (± c , 0)
∴ c = ±8
∵ It has Vertices at (± 17 , 0)
- The coordinates of the vertices are (± a , 0)
∴ a = ±17
∵ c² = a² - b²
- Substitute the values of c and a to find b
∴ (8)² = (17)² - b²
∴ 64 = 289 - b²
- Add b² to both sides
∴ b² + 64 = 289
- Subtract 64 from both sides
∴ b² = 225
- Take √ for both sides
∴ b = ± 15
∵ The equation of the ellipse is [tex]\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1[/tex]
- Substitute the values of a and b in it
∴ [tex]\frac{x^{2}}{(17)^{2}}+\frac{y^{2}}{(15)^{2}}=1[/tex] ⇒ [tex]\frac{x^{2}}{289}+\frac{y^{2}}{225}=1[/tex]
∴ The equation of the ellipse is [tex]\frac{x^{2}}{(17)^{2}}+\frac{y^{2}}{(15)^{2}}=1[/tex]
The standard form equation for this ellipse is (x²/17²) + (y²/15²) = 1.
To find the equation of an ellipse centered at the origin with foci at (±8,0) and vertices at (±17,0), we need to follow these steps:
Determine the values of 'a' and 'c': The vertices give us the value of 'a', which is the distance from the center to a vertex. Here, a = 17.
The foci give us the value of 'c', which is the distance from the center to a focus. Here, c = 8.
Using the relationship c² = a² - b², we can calculate 'b'.
c² = a² - b²
8² = 17² - b²
64 = 289 - b²
b² = 225
b = 15
So, the standard form of the equation of the ellipse is: (x²/17²) + (y²/15²) = 1
Two armadillos and three aardvarks sat in a five-seat row at the Animal Auditorium. What is the probability that the two animals on the ends of the row were both armadillos or both aardvarks?
Answers
Answer:
[tex]\dfrac{1}{15}[/tex]
Explanation:
The number of different ways in which the two armadillos would be at the ends of the row is 2:
[tex]P(2,2)=\dfrac{2!}{(2-2)!}=\dfrac{2}{0!}=2[/tex]
The number of different combinations in which two of the three aardvarks can sit at the ends of the row is P(3,2):
[tex]P(3,2)=\dfrac{3!}{(3-2)!}=\dfrac{3\times 2\times 1}{1}=6[/tex]
Therefore, there are 2 + 6 = 8 different ways in which the two animlas on the ends of the row were both armadillos or both aardvarks.
Now calculate the total number of different ways in which the animals can sit. It is P(5,5):
[tex]P(5,5)=\dfrac{5!}{(5-5)!}=5!=5\times 4\times 3\times 2\times 1=120[/tex]
Thus, the probability that the two animals on the ends of the row were both armadillos or both aardvarks is equal to the number of favorable outputs divided by the total number of possible outputs:
[tex]Probability=\dfrac{8}{120}=\dfrac{1}{15}[/tex]
Answer:
2/5
Step-by-step explanation:
2/5 1 1 1 1/4
A R R R A
2/20 or 1/10 is the odds that there will be an armadillo both ends
3/5 1 1 1 1/2
R A A R R
3/10 are the odds that there will be an aardvark on both ends and so you then have to add the two to get 4/10 or 2/5 which is the answer

Answers
Given:
ABC is a right triangle and AC = BC
The length of AB is [tex]AB=12\sqrt{2}[/tex]
We need to determine the length of each of the legs.
Length of AC and BC:
Let the length of AC and BC be x.
The length of AC and BC can be determined using the Pythagorean theorem.
Thus, we have;
[tex]AB^2=AC^2+CB^2[/tex]
Substituting the values, we have;
[tex](12\sqrt{2})^2=x^2+x^2[/tex]
Simplifying, we get;
[tex]288=2x^2[/tex]
Dividing both sides by 2, we get;
[tex]144=x^2[/tex]
Taking square root on both sides, we get;
[tex]12=x[/tex]
Thus, the length of each legs is 12 units.
Hence, the length of AC and BC are 12 units each.

Construct a consistent and independent system of equations that has ( − 1 , − 4 ) as its solution. Use x and y as your variables, and put your equations in the form A x + B y = C with A ≠ 0 and B ≠ 0 using the four answer boxes below. Note that there are many possible correct answers.
Answers
To create a consistent and independent system of equations with the solution (-1, -4), we generate two linear equations: 2x - 3y = 10 and 5x + 4y = -21, both of which are satisfied by the given solution.
Explanation:To construct an independent and consistent system of equations that has the solution (-1, -4), we can create two distinct linear equations where the point (-1, -4) satisfies both.
As an example, we choose two arbitrary linear equations, ensuring that they are not multiples of each other, and that they are satisfied by x = -1 and y = -4.
The general form of a linear equation is Ax + By = C.
For our first equation, we could have 2x - 3y = 2(-1) - 3(-4) = 10. To ensure the second equation is not a multiple of the first, we could choose 5x + 4y = 5(-1) + 4(-4) = -21.
The system of equations would then be:

Step-by-step explanation:
It's just what cubed is 64. The answer is 4 by the way since
4*4*4=16*4=64
The height (or length of one side) of the cube is 4 cm.
To find the cube's height, we need to use the formula for the volume of a cube.
The volume of a cube is given by the formula:
V = s³, where V is the volume and s is the length of one side of the cube.
In this case, we are given that the volume of the cube is 64 cubic cm. So, we can set up the equation:
64 = s³
To find the height (or length of one side), we need to take the cube root of both sides of the equation:
∛64 = ∛(s³)
Taking the cube root of 64, we get:
∛64 = 4

The diameter of a basketball is approximately 9.5 inches and the diameter of a tennis ball is approximately 2.5 inches .The volume of a basketball is about how many times greater than the volume of the tennis ball ?
Answers
Answer:
The correct answer is the basket ball is 54.87 times bigger in volume than the tennis ball.
Step-by-step explanation:
The diameter of a basketball is approximately given to be 9.5 inches.
The radius of the basket ball is given by [tex]\frac{9.5}{2}[/tex] = 4.75 inches.
The volume of the basket ball is given by = [tex]\frac{4}{3}[/tex] × π × [tex]radius^{3}[/tex] = 449.1012 cubic inches.
The diameter of a tennis ball is approximately given to be 2.5 inches.
The radius of the tennis ball is [tex]\frac{2.5}{2}[/tex] = 1.25 inches.
The volume of the tennis ball is given by = [tex]\frac{4}{3}[/tex] × π × [tex]radius^{3}[/tex] = 8.1845 cubic inches.
Ratio between the volume of the basketball and tennis is given by [tex]\frac{449.1011}{8.1845}[/tex] = 54.87.
Thus the volume of the basket ball is 54.87 times greater than the volume of the tennis ball.
Final answer:
To find how many times greater the volume of a basketball is than a tennis ball, calculate the volumes using the sphere volume formula and divide the basketball's volume by the tennis ball's volume, which yields approximately 54.86 times greater.
Explanation:
To determine how many times greater the volume of a basketball is compared to a tennis ball, we start by calculating the volume of each using the formula for the volume of a sphere, V = 4/3 π r3, where r is the radius of the sphere. The radius is half the diameter, so for the basketball, r = 9.5 inches / 2 = 4.75 inches, and for the tennis ball, r = 2.5 inches / 2 = 1.25 inches.
The volume of the basketball is approximately
Vbb = 4/3 π (4.75)3 = 448.74 cubic inches. The volume of the tennis ball is approximately
Vtb = 4/3 π (1.25)3 = 8.18 cubic inches.
To find out how many times greater the volume of the basketball is, we divide the volume of the basketball by the volume of the tennis ball:
448.74 cubic inches / 8.18 cubic inches ≈ 54.86. Therefore, the volume of a basketball is approximately 54.86 times greater than that of a tennis ball.

Pipe b can fill a pool in 9 hours. The amount of time it takes pipe c to fill the same pool is unknown. When pipes b & c are both open, the pool can be filled in 4 hours. If pipe c is filling the pool by itself how many hours will it take
Answers
Answer: it will take pipe c 7.2 hours to fill the pool.
Step-by-step explanation:
Let t represent the number of hours it will take pipe c to fill the pool alone. It means that the rate at which pipe c fills the pool per hour is 1/t
Pipe b can fill a pool in 9 hours. It means that the number of hours it takes pipe b to fill the pool alone per hour is 1/9
By working together, they would work simultaneously and their individual rates are additive. When pipes b & c are both open, the pool can be filled in 4 hours. It means that the rate at which both pipes fill the pool per hour is 1/4. Therefore,
1/t + 1/9 = 1/4
(9 + t)/9t = 1/4
Cross multiplying, it becomes
4(9 + t) = 9t
36 + 4t = 9t
9t - 4t = 36
5t = 36
t = 36/5
t = 7.2 hours

x^2 +y^2 -8x +4y +11 = 0
Step-by-step explanation:
The center of the given circle is located at (x, y) = (4, -2). Its radius is 3.
You know this because the center is halfway between the vertical and horizontal extremes, and the radius is half the difference of those extremes. You can determine this by counting squares, or "by eye," or by working with the coordinates of the extreme points.
For example, the horizontal extremes are (1, -2) and (7, -2). The diameter is the difference of the x-values: 7 -1 = 6, so the radius is 6/2 = 3. The x-coordinate of the center is (1+7)/2 = 4.
__
The standard form of the equation of a circle is ...
(x -h)^2 + (y -k)^2 = r^2
where (h, k) is the center, and r is the radius.
For this circle with center (4, -2) and radius 3, the standard form equation is ...
