finding an irrational number between which given pair of numbers supports the idea that irrational numbers are dense in real numbers? math 3
Answers
If there is another element of the same set between any two members of a set, we can say that the set is dense.
We'll show that the first choice—3.14 and pi—is the right one.
To prove that the set of irrational numbers contains a lot of real numbers, we must first discover an irrational number that lies between two specified real numbers.
In order to extend this to the real set, which is the union of irrational numbers and rational numbers, we should be able to find an irrational number between a rational number and an irrational number (or between an irrational number and a rational number). This is because we know that irrational numbers are dense (between two irrational numbers we can find another irrational number).
The first option, which has one of each, will then be the right choice.
Pi is irrational, while 3.14 is rational.
Finding an irrational number between these two indicates that the real set contains many irrational numbers.
(Note that the third option likewise has an irrational and a rational number, but the first one, [tex]e^{2}[/tex], is larger than the second one[tex]\sqrt{54}[/tex], thus it is written wrongly; for this reason, we did not choose it.)

1. You made a decision that you are doing to take care of the animals for the Claus family so they can go to a
warmer climate for their vacation this year. They will be on vacation the months of January and February. You will
be in North Pole, Alaska caring for their Reindeer, dogs, and hanging out with some of the Elves that take care of
things.
The weather for January 2022 and February 2022 are files found with the TGA.
Find the change in temperature (from the high and low) for the first day and last day of each month. How would
you have to pack for this trip?
2. What was the hardest part for you? Explain why.
Answers
Considering the climate of the North Pole, Alaska, we have seen that the change in the Temperature is 13°F and 14 °F respectively on the 1st and last day of the month respectively.
How to calculate the change in temperature?
From records, we know that Alaska usually has an average low temperature of 9°F and an average high temperature of 22°F in January.
However In February, Alaska's temperature usually ranges from an average low temperature of 12°F to an average high temperature of 26°F.
Thus, we can find the change in Temperature:
On 1st day of January , the Change in temperature is;
ΔT = Highest Temperature - lowest temperature
ΔT = 22°F - 9°F
ΔT = 13°F
On the 1st day of February, and then the last day of January, the change in temperature is;
ΔT= Highest Temperature - lowest temperature
ΔT = 26°F - 12°F
ΔT = 14 °F.
The hardest part will be to take take care of the animals since most of the animals only require a warm, secure, as well as protected area to reside in addition to sufficient food, drink, and exercise.

Jenna gets an iTunes gift card for her birthday and decides to buy some games and some music the music she likes costs $1.99 per song and the games costs $3.99 each if she buys a total of 12 items and spends $18.88 how many of each item did she buy
Answers
The number of songs and games Jenna bought is 9.5 and 2.5 respectively.
How many of each item did she buy?let
Number of songs bought = xNumber of games bought = yx + y = 12
1.99x + 3.99y = 18.88
From (1)
x = 12 - y
Substitute into (2)
1.99x + 3.99y = 18.88
1.99(12 - y) + 3.99y = 18.88
23.88 - 1.99y + 3.99y = 18.88
- 1.99y + 3.99y = 18.88 - 23.88
2y = -5
y = -5/2
y = 2.5
Substitute into (1)
x + y = 12
x + 2.5 = 12
x = 12 - 2.5
x = 9.5

Answers
Answer:
After the first translation, the coordinates of the vertices of the triangle will be X (3,-13), Y (0,-8), Z (-7, 1). After the second translation, the coordinates of the vertices will be X (5,-7), Y (2,-2), Z (-5, 7).
The final translation rule that maps the pre-image to the final image is a translation of 2 units right and 6 units up. This can be written as a translation rule of the form (x, y) -> (x + 2, y + 6).
Step-by-step explanation:
After the first translation the coordinates are:
(x, y) → (x - 3, y + 8)After the second translation the coordinates are:

Answers
The rate of increase in stock price is $ 0.10 per hour.
Calculating the Rate of increase:To calculate the rate of increase we need to know the increased amount per given time period
In this problem, we will calculate the stock price per given hour from that will calculate the rate of increase in a given situation.
Here we have
The price (in dollars) of a stock tracked from noon to three on a given day is shown by the function f(t) = 0.1(t - 2)³ + 6 where t is in hours.
Take t = 1
=> f(1) = 0.1(1 - 2)³ + 6
= 0.1(-1)³ + 6
= 0.1(-1) + 6
= - 0.1 + 6
= 5.9
Take t = 2
=> f(2) = 0.1(2 - 2)³ + 6
= 0.1(0)³ + 6
= 6
Take t = 3
=> f(3) = 0.1(3 - 2)³ + 6
= 0.1(1)³ + 6
= 0.1 + 6
= 6.1
The rate rate of increase = f(3) - f(2) = 6.1 - 6 = 0.1 ≅ $ 0.10
Therefore,
The rate of increase in stock price is $ 0.10 per hour.

What is Coordinate Geometry?The study of geometry using coordinate points is known as coordinate geometry (also known as analytical geometry). Finding the distance between two points, breaking lines into m:n segments, locating a line's midpoint, computing a triangle's area in the Cartesian plane, and other operations are all feasible using coordinate geometry.
A straight line is represented using its slope and a point on the line using point slope form. This indicates that the point slope form is used to get the equation of a line whose slope is "m" and which passes through the points (x 1, y 1). The equation of a straight line can be expressed in several ways. Point slope shape is one of them. Y - Y 1 = m(x - X 1) is the equation for the point slope form, where (x1, y1) is a randomly chosen point on the line and m is the slope of the line.
The slope of the line is 1.5
The Point through which the equation will satisfy is (6,12)
Therefore the equation of the line in Point-Slope form is
y - y1 = m ( x- x1)
⇒ y - 12 = 1.50 ( x - 6)

Answers
82.5 million was the profit the year before the profit decreased 20% to 66 million from one year to the next
What does profit means ?
Profit is the term used to describe the financial gain experienced when the revenue from a commercial activity exceeds the costs, costs, and taxes associated with maintaining that activity.
Any profits generated are returned to the company's owners, who can decide whether to keep the money for themselves, pay dividends to shareholders, or reinvest it in the company.
Entire revenue less total costs equals profit.
Companies report gross profit, operational profit, and net profit for accounting purposes (the "bottom line").
Investors are drawn to profitable businesses because these businesses either distribute their earnings as dividends to shareholders or invest them back into the business, which raises stock value.
According to the question Company lost 20% from its profit and it reached to 66 million that means
let X be the total profit of the year
X - loss percent = 66 millions
X - X (20/100) = 66 million
X-0.2X = 66 million
0.8X = 66 million
X= 66/0.8 million
X = 82.5 million
So, 82.5 million was the profit the year before
