The number of y-intercepts for g(x) is larger than that for f. (x). The standard form allows us to state that f(x) has vertex (0,0) and g(x) has vertex (2,-3).
what is coordinates ?When it comes to geometry, a coordinate system is a technique that uses one or more integers or coordinates to specify the exact location of points or other geometrical objects on a manifold, such as Euclidean space. Locating a point or item on a two-dimensional plane requires the usage of pairs of integer coordinates. Two numbers known as the x and y coordinates serve as a description of a point's location on a 2D plane. a collection of figures that signify exact locations. Most often, the figure contains two numerals. The first number denotes the distance from front to rear, and the second number denotes the distance from top to bottom. In (12.5), for example, there are 12 units below and 5 above.
given
The graph of f(x) is moved two units to the right and three units downward to get the graph of g. (x).
The standard form allows us to state that f(x) has vertex (0,0) and g(x) has vertex (2,-3).
Given that a>0, f(x) and g(x) are ascending parabola.
Since the origin is f(x vertex, )'s f(x) has just one y-intercept, or (0,0).
Given that g(x) is an upward parabola with a vertex at (2,-3), g(x) has two y-intercepts.
Because of this, the number of y-intercepts for g(x) is larger than that for f. (x).

Postal Service:
The Postal Service is an American indie pop supergroup from Seattle, Washington, consisting of singer Ben Gibber, producer Jimmy Tamborello, and backing vocalist Jenny Lewis.
The band released her only album Give Up in 2003 on her Sub Pop Records to mostly positive reviews. The album reached his number 114 spot on the US Billboard 200 album chart and was certified platinum by the Recording Industry Association of America. Laura Bergen joined the line-up for the entire tour, providing additional vocals and instruments, while Jen Wood and Jenny Lewis filled in for some shows.
According to the Question:
The mass of Moya's books = 70 kilograms
The mass of Moya's clothing = 127 kg
The difference between the both masses = 127 - 70 = 57kg
The cost per kg for books = $80 per kg
The cost per kg of clothing = $200
Therefore, the amount for the shipping cost for her school would be = (70×80) + (127 ×200)

Which of the following is Pythagorean triplet ?A. (6,8,10)B. (5,12,13)C. (7,13,15)D. (3,4,5)
Our Pythagorean triplets will be (6,8,10), (5,12,13), and (3,4,5).
So what is the Pythagorean triplet?
The square of the greatest number in a Pythagorean triplet equals the sum of the squares of the other two numbers.
The greatest side in a right-angled triangle is called the hypotenuse.
So, in our first triplet A(6,8,10) the greatest side is 10. So, hypotenuse = 10.
= [tex]hypotenuse^{2}[/tex] = [tex]10^{2}[/tex] = 100.
Now, [tex]6^{2}[/tex] + [tex]8^{2}[/tex] = 36 + 64 = 100.
[tex]10^{2}[/tex] = [tex]6^{2}[/tex] + [tex]8^{2}[/tex]
Thus A(6,8,10) is a Pythagorean triplet.
In the second case B(5,12,13) hypotenuse = 13.
= [tex]hypotenuse^{2}[/tex] = [tex]13^{2}[/tex] = 169.
Now, [tex]12^{2}[/tex] + [tex]5^{2}[/tex] = 144 + 25 = 169.
[tex]13^{2}[/tex] = [tex]12^{2}[/tex] + [tex]5^{2}[/tex]
Thus B(5,12,13) is a Pythagorean triplet.
In the Third case C(7,13,15) Hypotenuse = 15.
= [tex]hypotenuse^{2}[/tex] = [tex]15^{2}[/tex] = 225.
Now, [tex]7^{2}[/tex] + [tex]13^{2}[/tex] = 49 + 169 = 218.
[tex]15^{2}[/tex] [tex]\neq[/tex] [tex]7^{2}[/tex] + [tex]13^{2}[/tex]
Thus C(7,13,15) is not a Pythagorean Triplet.
In the last case D(3,4,5) Hypotenuse = 5.
= [tex]hypotenuse^{2}[/tex] = [tex]5^{2}[/tex] = 25.
Now, [tex]3^{2}[/tex] + [tex]4^{2}[/tex] = 9 + 16 = 25.
[tex]5^{2}[/tex] = [tex]3^{2}[/tex] + [tex]4^{2}[/tex]
Thus D(3,4,5) is a Pythagorean triplet.
Therefore our three results A(6,8,10) B(5,12,13) and D(3,4,5) are Pythagorean triplets.

Why is the base in the exponential function greater than 1?
The base in the exponential function is greater than 1 because exponential growth is defined as a constant multiplication of the original value, rather than a constant addition as in linear growth. A base greater than 1 results in a growth rate that increases over time, while a base less than 1 results in a growth rate that decreases over time.
THE EXPONENTIAL FUNCTIONThe exponential function is written as bˣ, where b is the base and x is the exponent. The base is the number that is being multiplied by itself a certain number of times, as determined by the exponent.
A base greater than 1 means that the value of the function is increasing at an increasing rate. This is because as the exponent (x) increases, the base (b) is being multiplied by itself more and more times, leading to a larger and larger result. This is known as exponential growth.
On the other hand, a base less than 1 means that the value of the function is decreasing at an decreasing rate. This is because as the exponent (x) increases, the base (b) is being multiplied by itself more and more times, leading to a smaller and smaller result. This is known as exponential decay.

One can use either the slope formula m = (y2 – y1)/(x2 – x1) or the standard line equation, y = mx + b to solve for the slope, m.
How do you determine the slope?You can find the slope of the line by determining the rise and run of two locations on the line. The rise is the vertical change between two places, while the run is the horizontal change. The slope is calculated by dividing the climb by the run: Riserun = Slope Slope = rise and run.
Depending on the form of the equation in front of you, the procedure for calculating the slope will differ. If the equation is written as y = mx + c, the slope (or gradient) is simply m. If the equation is not in this form, attempt rearrangement. You will need to do the following to determine the gradient of additional polynomials:

We have to determine how can we enlarge a triangle by a scale factor of 3.
We concluded that
To find the scale factor of enlargement, divide the longer side by the short side. 6 ÷ 2 = 3 and so, the scale factor is 3.
This means that all of the sides on the smaller shape have been multiplied by 3. It also means that all of the sides on the larger shape can be divided by 3 to make the smaller shape.

Eric is riding his bicycle. He rides for kilometers at a speed of kilometers per hour. For how many hours does he ride?
In a certain country, the car number plate is formed by 4 digits from the digits 1, 2, 3, 4, 5, 6, 7, 8 and 9 followed by 3 letters from the alphabet. How many number plates can be formed if neither the digits nor the letters are repeated?.
Answer:
47,174,400 possible number plates
See important note at the bottom of the explanation
Step-by-step explanation:
The easiest way to handle a problem of this type is to note the following
There are 9 digits 1-9 that we can use for the first four characters of the license plate
This means that for the first digit there are all 9 possibilitiesFor the second digit, since there is no repetition, there exists only 8 possibilitiesFor the third spot, there are 7 possibilitiesFor the 4th spot there are 6 possibilitiesSo the number of ways to arrange the first 4 digits without repetition is
9 x 8 x 7 x 6 = 3024 possible ways
For the letters, assuming that we are using the English alphabet, the 5th spot where the first letter after the numbers is can be done in 26 possible ways since there are 26 alphabets.
For the second letter that will leave us with 25 possibilities
For the third and final spot there are 24 possibilities
This means that, without repetition, the letters can be arranged in 26 x 25 x 24 ways = 15,600 ways
Together we can arrange the digits and letters in 3024 x 15600 ways which works out to
3024 x 15600 = 47,174,400 ways or possible number plates
Or we could simply write this in one step as
9 x 8 x 7 x 6 x 26 x 25 x 24 = 47,174,400 ways or possible number plates
Note
Even though there are 10 digits 0 - 9, the question clearly states that we should choose from digits 1 through 9 only.
If we are allowed to use all 10 digits the first 4 digits can be put together in 10 x 9 x 8 x 7 = 78,624,000 ways
You should clarify this with your teacher.
