what is perfect cube
Answer:
The perfect cube is the result of multiplying the same integer three times. Multiplying the number 4 three times, for example, yields 64. As a result, the number 64 is a perfect cube. Perfect cube = number x number x number.
Step-by-step explanation:
Perfect cube numbers can be obtained by multiplying every number thrice by itself. For example, 1 × 1 × 1 = 1 and 2 × 2 × 2 = 8 and so on. The list of perfect cubes from 1 to 10 is as follows: 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1000.

. Find the factors of (ϰ² - 25)
Answer:
(x - 5)(x + 5)
Step-by-step explanation:
x² - 25 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
x² - 25
= x² - 5²

Plug a point in each equation given.
Point I'm using: (1, 5650)
Mateo's Equation: y= 125x+5775
5650= 125(1)+5775
5650=5900
False. His equation is not correct.
Do this for the rest of equations.

What algebraic rule did you use to preform this
translation????
Answer:
In geometry, a transformation is an operation that moves, flips, or changes a shape (called the preimage) to create a
new shape (called the image). A translation is a type of transformation that moves each point in a figure the same
distance in the same direction. Translations are often referred to as slides. You can describe a translation using words
like "moved up 3 and over 5 to the left" or with notation. There are two types of notation to know.
1. One notation looks like T(3, 5). This notation tells you to add 3 to the x values and add 5 to the y values.
2. The second notation is a mapping rule of the form (x, y) → (x−7, y+5). This notation tells you that the x and
y coordinates are translated to x−7 and y+5.

Solve the equation for the y–value and choose whether it is a direct variation or inverse variation
-4x + y = 0
Answer: Choice C
y = 4x
Direct variation
=====================================================
Explanation:
We add 4x to both sides to isolate y. That leads to y = 4x
This is a direct variation equation because it's in the form y = kx, for some constant k.
you roll a standard die. you win $12 if you roll a six, $6 if you roll a one, and $0 if you roll anything else. what is the expected value of a single roll?
Answer:
$0
Step-by-step explanation:
The chance of winning money is 2/6 -> 1/3, and sense 2/3 is larger than 1/3, we can conclude the expected value of a single roll is $0.
(I may be doing this problem wrong as I don't have context for what you're currently working on, but I hope this helps. Have a nice day!)
Answer:

Which shape does our galaxy have?(1 point)
circular
spiral
irregular
elliptical
Answer: spiral
Step-by-step explanation:
The shape that our galaxy have is : Spiral, because "Spiral-Structure" provides the Milky-Way its name. option (b) is correct.
Our galaxy, the Milky-Way, is classified as a spiral galaxy. Spiral-Galaxies are characterized by their distinct spiral arms that radiate from a central bulge. These arms contain stars, gas, dust, and other celestial objects.
The Milky-Way's spiral arms are home to a significant portion of its stars and are formed due to the gravitational interactions between different parts of the galaxy. This spiral structure gives the Milky-Way its name and appearance when observed from certain angles.
Spiral galaxies are one of the most common types of galaxies in the universe, and they play a crucial role in our understanding of cosmic structures.
Therefore, the correct option is (b).

A bike rental costs $8 per hour. Desiree has a coupon for 2 free hours. To find how many hours she can rent with $40, Desiree sets up the equation 8(x – 2) = 40, where x is the number of hours.
Answer:
40
Step-by-step explanation:
8x = 56
8x + 16 = 40
x = 3
8x = 24
x = 7
8x – 16 = 40
8(x – 2) = 40

[tex]\sf 2x+7+8x=35[/tex]
Answer:
x=14/5
Step-by-step explanation:
Group like terms
2x+8x+7=35
Add similar elements: 2x+8x=10x
10x+7=35
Subtract 7 from both sides:
10x+7−7=35−7
Simplify
10x=28
Divide both sides by 10
10x/10 =28/10

Compute the average rate of change of f(x)=(x+4)/(x-3) over the interval [5,7].
A)4/3
B)7/8
C)-7/8
D)-4/3
(Image attached below)
Answer:
C) - 7/8Step-by-step explanation:
Average rate of change is:
[f(7) - f(5)]/(7 - 5)Find the values and substitute into expression:
f(7) = (7 + 4)/(7 - 3) = 11/4f(5) = (5 + 4)/(5 - 3) = 9/2 = 18/4Find the rate of change:
(11/4 - 18/4)/2 = (-7/4)/2 = - 7/8Correct choice is C
