Answer:
A domain is the possible x-values in a ordered pair or an input value in a table
Step-by-step explanation:
I learned this by reading a lesson about it.
Also, here are some additional tips given from me to any of you when writing a domain or range!
When you write a domain or range:
1. List the numbers separated by commas instead of braces (if it is listed in braces and not in a table or ordered pair)
2. List the value(s) from least to greatest
Note: Duplicate numbers listed in an table or braces should only be listed once.

Evaluate the radical. 512−−−√3 Enter your answer in the box.
Answer: The Answer is 8
Step-by-step explanation: It's right I just got done with the quiz And got an A+ I hope it helps!
The cube root of 512 is 8, the value of ∛512 is 8.
What is Number system?A number system is defined as a system of writing to express numbers.
The given expression is ∛512
To evaluate the cube root of 512, we can factor 512 as follows:
512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2
We can then group the factors into sets of three, as follows:
512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2) = 8 × 8 × 8
Therefore, we have:
∛512 = ∛(8 × 8 × 8)
= 8
Hence, the cube root of 512 is 8.

If we have the graph of either a function or its derivative, we can find an approximate graph for the other function. This is because when a function is increasing, the derivative is positive, and when the function is decreasing, the derivative is negative.

PLEASE HELP!!! 3x - x - 5 = 2(x+2)-9
Answer:
Infinite Solutions
Step-by-step explanation:
To solve for this problem, we want to isolate x on one side of the equation.
Apply the distributive property on the right side:
[tex]3x - x - 5 = 2x+4 -9[/tex]
Combine like terms:
[tex]2x - 5 = 2x - 5[/tex]
Woah, we have the exact same thing on both sides of the equation. This means that we have infinite solutions, aka any value of x will satisfy this equation.
Test it out! Any value of x, whether its 1, 5, or 10000 will satisfy the equation.
So this has infinite solutions.

Answer:
-5/9
Step-by-step explanation:
the slope of line b is 9/5
because (10-1)/(9-4)=9/5
a perpindicular line has a slope opposite and inverse of the other one, so the slope of c is -5/9

c = -20
Step-by-step explanation:
-21=1/2c-11
-21+11=1/2c
-10=1/2c
-10*2=c
-20=c
Answer:
c = - 20
Step-by-step explanation:
Given
- 21 = [tex]\frac{1}{2}[/tex] c - 11 ( add 11 to both sides )
- 10 = [tex]\frac{1}{2}[/tex] c ( multiply both sides by 2 to clear the fraction )

u is the number of hours walking up a hill and (u-2) is the number of hours sledding down the hill
Answer:
u= 2.5
Step-by-step explanation:
Using BIDMAS
Step 1: Expand the bracket
9(u-2) + 1.5u=8.25
9u-18+1.5u=8.25
Step 2: collect like terms
9u+1.5u=8.25+18
10.5u=26.25
Step 3: Divide both sides by 10.5 to get u
u= [tex]\frac{26.25}{10.5}[/tex]= 2.5

PLEASE HELP!!!! Explain why a quadratic equation with a positive discriminant has two real solutions, a quadratic equation with a negative discriminant has no real solution, and a quadratic equation with a discriminant of zero has one real solution.
Hey there! I'm happy to help!
In the quadratic formula, the discriminant is square rooted. In this formula you have a ± before this radical. If the discriminant is positive, the solution can be either subtracting or adding the number, so there are 2 real solutions.
If it is 0, subtracting or adding are the same, so there will be just one solution.
You cannot have a negative square root. It is impossible with real numbers, so there are no real solutions.
I hope that this helps! Have a wonderful day! :D
The zeroes based on nature of discriminant is described below.
We know that,
A quadratic equation is of the form ax + bx + c = 0,
Where a, b, and c are constants and x is the variable.
The discriminant of a quadratic equation is given by the expression,
⇒ b² - 4ac.
If the discriminant is positive (b² - 4ac > 0),
Then the quadratic equation has two real solutions.
This is because the quadratic formula, which gives the solutions of the quadratic equation, involves the square root of the discriminant.
Since the discriminant is positive, the square root is a real number, resulting in two distinct real solutions.
If the discriminant is negative (b² - 4ac < 0),
The square root of the discriminant is an imaginary number since it involves a negative integer's square root.
Given that the discriminant is a component of the quadratic formula,
if it is negative, the quadratic formula will include computing the square root of a negative integer, which is not a real number.
This is due to the fact that solving the quadratic equation requires obtaining the square root of the discriminant, and a negative square root is not a real integer.
In conclusion, there are no actual solutions to a quadratic equation with a negative discriminant since the solutions entail calculating the square root of a negative.
When the discriminant is zero,
it means that the quadratic equation has only one solution, which is a real number.
This is because the quadratic formula for finding the solutions of the quadratic equation reduces to a simpler formula when the discriminant is zero. Specifically,
The quadratic formula becomes,
x = -b/2a This formula gives us the only solution of the quadratic equation when the discriminant is zero.

The robber stole only 25 pounds of quarters out of the coin machine. Quarters are weighed in ounces. If there are 16 ounces in 1 pound, how many ounces of quarters were stolen?
Answer:
400 ounces
Step-by-step explanation:
x pound(s) = (16*x) ounces
25 pounds=(16*25) ounces
25 pounds= 400 ounces
400 ounces of quarters were stolen.
Given,
The robber stole only 25 pounds of quarters out of the coin machine. Quarters are weighed in ounces.
If there are 16 ounces in 1 pound.
We need to find out how many ounces of quarters were stolen.
How many ounces in 1 pound?16 ounces = 1 pound
Find how many pounds of quarters were stolen.
= 25 pounds of quarters.
Convert 25 pounds of quarters into ounces of quarters.
1 pound = 16 ounces
Multiplying 25 on both sides.
25 x 1 pound = 25 x 16 ounces.
25 pounds = 400 ounces.
This means 25 pounds of quarters is 400 ounces of quarters.
Thus 400 ounces of quarters were stolen.
