Answer:

4 cm

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

Therefore, the height (or length of one side) of the cube is 4 cm.

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.

Answer: The hook would be 2.2 inches (approximately) above the top of the frame

Step-by-step explanation: Please refer to the picture attached for further details.

The top of the picture frame has been given as 9 inches and a 10 inch ribbon has been attached in order to hang it on a wall. The ribbon at the point of being hung up would be divided into 5 inches on either side (as shown in the picture). The line from the tip/hook down to the frame would divide the length of the frame into two equal lengths, that is 4.5 inches on either side of the hook. This would effectively give us two similar right angled triangles with sides 5 inches, 4.5 inches and a third side yet unknown. That third side is the distance from the hook to the top of the frame. The distance is calculated by using the Pythagoras theorem which states as follows;

AC^2 = AB^2 + BC^2

Where AC is the hypotenuse (longest side) and AB and BC are the other two sides

5^2 = 4.5^2 + BC^2

25 = 20.25 + BC^2

Subtract 20.25 from both sides of the equation

4.75 = BC^2

Add the square root sign to both sides of the equation

2.1794 = BC

Rounded up to the nearest tenth, the distance from the hook to the top of the frame will be 2.2 inches

To find the distance above the frame for hanging, use the Pythagorean theorem by considering the diagonal created by the ribbon. The hook needs to be approximately 5.39 inches above the top of the frame.

To find how far above the top of the frame the hook needs to be, we need to consider the diagonal of the frame created by the ribbon. Using the Pythagorean theorem, we can calculate this distance.

Therefore, the hook needs to be approximately 5.39 inches above the top of the frame.

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

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.

Answer:

  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 ...

  (x -4)^2 + (y +2)^2 = 9

General form has the parentheses removed and the polynomial written in descending powers of the variables:

  x^2 -8x +16 +y^2 +4y +4 = 9

  x^2 +y^2 -8x +4y +11 = 0

Answer:

You played 4 games

Step-by-step explanation:

You start with $18 and subtract 6 from the entry fee. Then, you divide the 12 you got from that and divide it by 3

Final answer:

To determine the number of games played, subtract the access fee from the total cost and then divide by the per-game price. In this case, the student paid for an access fee of $6, and played 4 games at $3 each to reach a total cost of $18.

Explanation:

The question posed is a basic algebra problem involving a fixed entry fee and a variable cost per game. The given information states that the access fee is $6 and the per-unit price, which in this case is the cost per game, is $3. If the total amount paid was $18, the number of games played can be calculated.

To solve, let's denote the number of games played as x. The total cost is made up of a fixed access fee plus the cost of the games played. The expression for the total cost is thus $6 (access fee) + $3x (cost of games).

The equation based on the total amount paid would be:

6 + 3x = 18

To find the value of x, we subtract the access fee from the total amount paid:

18 - 6 = 3x

That simplifies to:

12 = 3x

Which can then be solved by dividing both sides by 3:

x = 12 / 3

x = 4

The student thus played 4 games.

Answer:

Expression:

[tex]\frac{9}{8}+(-\frac{1}{2})=\frac{5}{8}[/tex]

Step-by-step explanation:

We are given that

Bryce traveled distance from his home=[tex]\frac{9}{8}miles[/tex]

Bryce traveled distance back=[tex]\frac{1}{2}miles[/tex]

We have to find the expression and then simplify.

According to question

Total distance traveled by Bryce

=[tex]\frac{9}{8}+(-\frac{1}{2})[/tex]

This is required expression.

Total distance traveled by Bryce=[tex]\frac{9-4}{8}=\frac{5}{8}miles[/tex]

Hence, the total distance traveled by Bryce from his home=[tex]\frac{5}{8}miles[/tex]

Final answer:

To find the total distance Bryce walked, we add 9/8 miles to 1/2 mile, which equals 13/8 miles or simplified to 1 5/8 miles.

Explanation:

Bryce initially walks 9/8 miles from home. On his way back, he walks 1/2 mile before meeting up with his friend Mya. To describe this situation with an expression and simplify it, we add these distances together:

Total distance walked = 9/8 miles + 1/2 mile

To simplify, find a common denominator (which in this case is 8), and then add the numerators:

Total distance walked = (9/8) + (4/8)

Total distance walked = (9 + 4) / 8

Total distance walked = 13/8

Total distance walked = 1 5/8 miles

This is the sum describing the distance Bryce walked before meeting Mya, which simplifies to 1 and 5/8 miles.

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 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
