What is the complete factorization of r2 - 6r - 9s2 + 9? A) (r - 3 + 3s)(r - 3 - 3s) B) (r + 3 + 3s)(r - 3 - 3s) C) (r - 3 + 3s)(r - 3 + 3s)
We have factorized the expression 'r2 - 6r - 9s2 + 9' into (r - 3)^2 - (3s)^2 and then used the difference of squares formula to find the factorization as (r - 3 + 3s)(r - 3 - 3s). So the correct answer is option A)
Explanation:The question asked for the complete factorization of the expression r2 - 6r - 9s2 + 9. To factorize this, we can rewrite it into the formula form of a perfect square, which is a^2 - 2ab + b^2 = (a - b)^2.
Our expression fits this form when a = r and b = 3s. Following this, we can rewrite the expression as (r - 3)^2 - (3s)^2 = (r - 3 + 3s)(r - 3 - 3s). Therefore, the correct answer is option A) (r - 3 + 3s)(r - 3 - 3s)

Solve for y in terms of x.
2/3y - 4 = x
Please help . Time is critical for me in school rn
Answer:
[tex]y=\frac{3}{2}(x+4)[/tex]
Step-by-step explanation:
We are given
[tex]\frac{2}{3}y-4=x[/tex]
Since, we have to solve for y
so, we will isolate y on anyone side
Firstly, we add both sides by 4
[tex]\frac{2}{3}y-4+4=x+4[/tex]
[tex]\frac{2}{3}y=x+4[/tex]
Multiply both sides by 3
[tex]3\times \frac{2}{3}y=3\times(x+4)[/tex]
[tex]2y=3\times(x+4)[/tex]
now, we can divide both sides by 2
and we get
[tex]y=\frac{3}{2}(x+4)[/tex]

Nancy wove a pot holder with a area of 80 square inches. The lengths and widths of the sides are whole numbers. Which dimensions make the most sense for a potholder? Explain
Final answer:
The dimensions of 8 inches by 10 inches make the most sense for a pot holder with an area of 80 square inches, as they are practical in size. This is similar to the concept of a square whose area scales by the square of the side length when dimensions are increased by a scale factor.
Explanation:
The student asked which dimensions make the most sense for a potholder with an area of 80 square inches where the lengths and widths are whole numbers. It's crucial to consider practical sizes that would be convenient for handling hot items without being too large or too small.
Common dimensions for a pot holder could be 8 inches by 10 inches since 8 x 10 equals 80 square inches, and these measurements are suitable for a pot holder. These measurements make sense as they provide enough space to protect hands from heat but are not excessively large, making them impractical. They are comparable to the measurements of a placemat, which is typically used in dining settings and is also manageable in size.
Comparing this to the information about squares and areas, if Marta has a square with side length 4 inches, its area would be 16 square inches. A similar square with side lengths that are twice as long (8 inches) would have an area of 64 square inches because the area is proportional to the square of the side length. Consequently, the area of the larger square is four times that of the smaller square (since 2 squared is 4).
This example of scaling dimensions and areas can assist in understanding how dimensions that are whole numbers relate to the area and the practical use of an object. The mentioned scale factor is integral in determining how the area increases with increased side lengths.
If the diameter of a penny is 19.05 millimeters and the width of each penny is 1.52 millimeters, what is the approximate volume of the roll of pennies? Use 3.14 for π and round your answer to the nearest tenth.
Answer:
Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).
Step-by-step explanation:
Given : diameter of a penny is 19.05 millimeters and the width of each penny is 1.52 millimeters.
To find : volume of the roll of pennies.
Solution : We have given that
Diameter of a penny = 19.05 millimeters.
Width of each penny = 1.52 millimeters.
Volume of cylindrical roll of penny = pi * r² * h
Where, r = radius , h =height
Radius = [tex]\frac{Diameter}{2}[/tex]
Radius= [tex]\frac{19.05}{2}[/tex].
Radius = 9.525 mm
Plugging the values of r , h and pi = 1.14.
Volume of cylindrical roll of penny = pi * r² * h
Volume of cylindrical roll of penny =3.14 * (9.525)² * 1.52
Volume of cylindrical roll of penny = 433.02 mm³
Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).
Therefore, Volume of cylindrical roll of penny = 433 mm³ ( nearest tenth).

When paying off debts ,you should ___ .
A. pay the minimum
B.pay as much as possible
C.pay slightly more than the minimum
D.pay exactly half of what you owe
B.pay as much as possible
Step-by-step explanation:
Debts are unpaid money that a person owes to its lenders. The lender can be any bank or any other financial institution or any person.
Long accumulated debts on banks, if not paid, can result in a person filing for bankruptcy. So, it is always good if you pay your debts on time.
Paying minimum or slightly more than minimum amount will result in paying more in the near future. It is possible that if you always pay minimum amount, you will not be able to clear debts anytime soon.
So, its best that if you have money, always pay as much as possible to get rid of your debt.

Which table represents a linear function? (Will give brainliest)
Answer:
x y
1 0.5
2 1
3 1.5
4 2
Table (1) represents a linear functions.
Step-by-step explanation:
Given : Tables with x and y values.
We have to choose the table that represents a linear function.
Since, A linear function is of the form y = mx + c , where m is slope and c is y- intercept
Consider the table (1),
x y
1 0.5
2 1
3 1.5
4 2
Consider two points , (1,0.5) and (2,1)
0.5 = m(1) + c
and 1 = m(2) + c
Subtract both , we have,
m = 0.5
and Put m = 0.5 back, we have,
c = 0
Thus, y = 0.5x
Thus, Table (1) represents a linear functions.

The scale factor of the dilation of figure ABCD is?
2 is the scale factor of the dilation of figure ABCD
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
The scale factor of a dilation is a number that represents how much a figure's size alters following a dilation. It is the ratio of similar sides' lengths in the original and dilated figures.
A figure is stretched or extended if the scale factor is larger than 1, and lowered or shrunk if it is less than 1. If the scale factor is 1, the dilation has no effect on the figure; if it is less than 1, the figure is reflected beyond the line of dilation.
The scale factor is represented by the symbol k, and its value may be determined using the formula below:
k = Length of the corresponding side in the dilated figure / Length of the corresponding side in the original figure.
On the given figure,
Before dilation the measurement of the side AD = 1 unit.
After dilation the measurement of the same side = 2 units
Thus, from the formula
k = 2/1
k=2
Therefore, The scale factor of the dilation of Figure ABCD is 2.

Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read. Let P(t), left parenthesis, t, right parenthesis denote the number of pages to read P as a function of time t (measured in hours). Write the function's formula
The function's formula that represents the number of pages Naoya has left to read at time t would be P(t) = 570 - 55t.
Explanation:From the information given we know that Naoya reads at a rate of 55 pages per hour. After 4 hours of reading, he still has 350 pages left to read. This means that before he started reading, he had (55 pages/hour * 4 hours + 350 pages) = 570 pages in total. Since he reads at constant rate, the function that describes the remaining pages to read would be P(t) = 570 - 55t, where t represents the time in hours and P(t) is the number of pages left to read.
