Answer:
Vertical stretch and reflection across the x axis
Step-by-step explanation:
Vertical stretch and reflection across the x-axis are the odd functions.
What is a vertical stretch?Vertical stretch occurs when a base graph is multiplied by a certain factor that is greater than 1. This results in the graph being pulled outward but retaining the input values (or x). When a function is vertically stretched, we expect its graph's y values to be farther from the x-axis.
What is a vertical reflection over the x-axis?Another transformation that can be applied to a function is a reflection over the x– or y-axis. A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis.

The area of a square is 400 square units. Select all the statements that would be true if the length of each side of the square increased by one unit.
A-The area of the square would be a rational number.
B-The area of the square would be an irrational number
C-Each side length would be a perfect square.
D-The area of the square would be a perfect square.d
E -The area of the square would be a nonterminating, nonrepeating decimal.
PLEASE ANSWER ASAP!!!! WILL GIVE BRAINLIEST!
Answer:
A and D
Step-by-step explanation:
Given that the area of a square = 400 units² = s²
Where s is one side length of the square.
It means that the side length (s) = √400 = 20
If the length of each side length increase by 1 units, new side length = 21 units
Area of new square = 21² = 441
The following statements would be true if the side length was increased by 1 units:
A. "The area of the square would be a rational number"
441 is a rational number, because a rational number is a quotient of two integers.
441 and 1 are two integers. Their quotient = 441. I.e. 441 ÷ 1 = 441
D. "The area of the square would be a perfect square".
A number is considered a perfect square if it can be expressed as a product of two equal integers.
441 can be expressed as 21*21

Why is the square root of a non perfect square always irrational number ?
Answer:
The square root of any prime number must be an irrational number. For example, because of this proof we can quickly determine that √3, √5, √7, or √11 are irrational numbers...
Answer:
Yes, unless X is a perfect square, sqrt(X) is irrational
Step-by-step explanation:
The proof where X= 2 is an example of the general proof: Supposesqrt(X) is rational, then there exists integers p and q such that (p/q)^2 = 2, we can cancel any common factors out of p and q so these are the simplest integers which satisfy the equation.
DeAndre Jordan has been working on his free throw shooting for the 2020-21 NBA season and it's not going well. After his workouts, he's been shooting 50% from the line in an empty gym. He shoots a string of 15, and then based on the number he makes, he has the following exercise routine. You can assume all of his free-throws have the same probability of being made (50%) and are independent of another.
If he makes more than 10 *** or less than 5. he does 40 push-ups. (A)
If he makes less than 8. he does 15 pull-ups. (B)
If he makes exactly 6 (his jersey number). he runs the length of the court and back 10 times.
If he makes between 3 and 12 (inclusive). he drinks a very tall glass of water. (D)
(He may do multiple exercises,)

The value after simplifying the expression 3² + 8 ÷ 2 - (4 + 3) is 6 by using PEMDAS rule.
To simplify the expression 3² + 8 ÷ 2 - (4 + 3), follow the order of operations (PEMDAS/BODMAS):
P - Parentheses first
E - Exponents (i.e., powers and square roots, etc.)
MD - Multiplication and Division (left to right)
AS - Addition and Subtraction (left to right)
Start with the exponent:
3² = 3 × 3 = 9.
Next, perform the division:
8 ÷ 2 = 4.
Now, deal with the parentheses:
(4 + 3) = 7.
Finally, perform the addition and subtraction from left to right:
9 + 4 - 7
= 6.
So, the simplified expression is 6.

According to data from the U.S. Census Bureau, in 2010 21,495 workers in Wake County had a daily commute between 45 and 59 minutes. By 2016 the number of workers with this long of a commute had increased by 82%. How many Wake County workers had a 45-59 minute commute in 2016?
=======================================================
Explanation:
Ignore the "45" and "59" as they aren't used in this problem. The year numbers don't matter either. These numbers are either thrown in as filler or distraction.
We're basically being asked "we started with 21,495 and increased by 82%, what is the new value?"
Take 82% of this to get 0.82*21495 = 17,625.9 which rounds to 17,626 since it doesn't make sense to have a decimal or fractional portion of a person. So the number of workers has increased by about 17,626 people.
Add this to the original amount to get 21,495 + 17,626 = 39,121 which is the answer
--------------
As a shortcut, you could multiply 21495 by 1.82 to indicate an 82% increase
1.82*21495 = 39,120.9 which rounds to 39,121
The length of a rectangular classroom floor is 6 feet more than twice the width the perimeter is 30 feet. What is the length and width of the classroom?
Answer:
Length = 12.75 feet
Width= 2.25 feet
Step-by-step explanation:
Let the length = x
Let the width= y
The length of a rectangular classroom floor is 6 feet more than twice the width
X= 6+2y
The perimeter is 30 feet.
Perimeter= 2(length+width)
Perimeter= 2(x+y)
30= 2x +2y
But x= 6+2y
30 = 2(6+2y) +2y
30= 12 +4y +4y
30-12= 8y
18= 8y
2.25 = y
30= 2x +2y
30= 2x +2(2.25)
30- 4.5= 2x
25.5= 2x
12.75= x
Length = 12.75 feet
Width= 2.25 feet

D. x= 5
pls help me my grade is depending on it
Answer:
d. x = 5
Step-by-step explanation:
Solve for x:
x - 3 = 7 - x
Hint: | Move terms with x to the left hand side.
Add x to both sides:
x + x - 3 = (x - x) + 7
Hint: | Look for the difference of two identical terms.
x - x = 0:
x + x - 3 = 7
Hint: | Add like terms in x + x - 3.
x + x = 2 x:
2 x - 3 = 7
Hint: | Isolate terms with x to the left hand side.
Add 3 to both sides:
2 x + (3 - 3) = 3 + 7
Hint: | Look for the difference of two identical terms.
3 - 3 = 0:
2 x = 7 + 3
Hint: | Evaluate 7 + 3.
7 + 3 = 10:
2 x = 10
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 2 x = 10 by 2:
(2 x)/2 = 10/2
Hint: | Any nonzero number divided by itself is one.
2/2 = 1:
x = 10/2
Hint: | Reduce 10/2 to lowest terms. Start by finding the GCD of 10 and 2.
The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:

You run to the store on your way home from school. You want to buy some Doritos. Should you buy the regular size bag or the party size bag? Calculate the unit price for each size and determine which one is the better buy. 15 oz. Party Size Doritos $3.98 9.75 oz. Doritos $2.98
Answer:
15 ounce bag is cheaper per ounce than 9.75 ounce bag.
Step-by-step explanation:
For this problem, you should simply take the cost divide by the size for each to find the price per ounce.
$3.98 / 15oz == $0.265 per ounce
$2.98 / 9.75oz == $0.306 per ounce
Note that the 15 oz bag is a better price per ounce than the 9.75 oz bag.
As to what bag you should buy, that really should depend on more factors than just what's best per ounce. For instance, are you really hungry enough for 15 ounces of doritos, or will 9.75 do just fine? Also, do you even have the extra dollar it would cost to buy the bigger bag? Just some stuff to think about.

Answer : The correct option is, (B) 1500 cubic yards.
Step-by-step explanation :
Formula used to calculate the volume of square pyramid is:
[tex]V=\frac{a^2\times h}{3}[/tex]
where,
V = volume of pyramid
a = base edge of pyramid
h = height of pyramid
Given:
Base edge of pyramid = 15 yards
Height of pyramid = 20 yards
Now putting all the given values in the above formula, we get:
[tex]V=\frac{a^2\times h}{3}[/tex]
[tex]V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}[/tex]

ED 2020
The required rule describes the rotation about the origin is given as (-x, -y). And the measure of rotation is 180°.
What is the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
The coordinate of the given point is (1, 1), and after rotation coordinates are (-1, -1) about the origin. It shifted from 1st quadrat to the 3rd quadrant. It implies,
The point rotated with an angle of 180° so that its coordinates were translated by formula,
(x, y) ⇒ (-x, -y).
Thus, the required rule describes the rotation about the origin is given as (-x, -y). And the measure of rotation is 180°.
