Option A satisfy the equation after simplification that is y(y-1) / 3(y+1) when the equation that is 36y / (y²- 2y+1) ÷ 12y² / (y²-1)
Given that,
We have to simplify the equation that is
36y / (y²- 2y+1) ÷ 12y² / (y²-1)
We know that,
We have to divide the equations,
36y / (y²- 2y+1) ÷ 12y² / (y²-1)
We can write in multiplication form that is
36y / (y²- 2y+1) × (y²-1) / 12y²
Now we can divide the 36y by 12 y² we get 3/y
3(y²-1)/ y(y²- 2y+1)
We can write the y²-1 as (y-1)(y+1) and by formula y²-2y+1 as (y-1)²
3(y-1) (y+1)/ y (y-1)²
Now we can divide
3(y+1)/ y(y-1)
So we can see in the options
Therefore, Option A satisfy the equation after simplification that is y(y-1) / 3(y+1) when the equation that is 36y / (y²- 2y+1) ÷ 12y² / (y²-1)

The Principal when calculated quarterly will give a sum of 2900 + (2.525)^4t at a rate of 6.1% interest
What is Compound Interest?
Compound interest is usually referred to as "interest on interest." Compound interest can work in your favour as your assets increase over time, but it can also work against you if you're paying off debt, such as credit cards. A calculator can assist in estimating how much money compound interest will generate over time.
Given that the Principal amount is $2900
and the Rate of Interest is 6.1%
Since, the interest is calculated quarterly
Amount = Principal * (1 + Rate/4)^4*Time
Amount = 2900 + (1 + 6.1/4)^4t
Amount = 2900 + (10.1/4)^4t
Amount = 2900 + (2.525)^4t

The number of times both spins will be even numbers in 200 spins is (b) 50
How to predict the number of times both spins will be even numbers.From the question, we have the following parameters that can be used in our computation:
Sections on the spinner = 1, 2, 3, 4, 5, and 6
Also, from the question;
We have the following statement
The theoretical probability of both spins being even numbers is 9 over 36.
This means that
P(Both even) = 9/36
Lastly, we have
Times of experiment = 200
So, we have
Outcomes of both even = P(Both even) * Times of experiment

Why were goods planned to become obsolete?
A. So that the company would become known for quality goods
B. So that people would keep buying new things
C. So that companies could protect their brand
D. So that people could save as much money as possible
Answer: B
Step-by-step explanation: B. So that people would keep buying new things
Goods are often planned to become obsolete in order to encourage people to continue buying new things. This can be done by intentionally designing products with a limited lifespan or by using materials that are prone to wear and tear. Companies may also release new versions of products or discontinue support for older models in order to encourage consumers to upgrade to the latest version. By making their products become obsolete, companies can create a sense of urgency for consumers to keep buying new things and maintain their sales.

Answer:
Lyric ran faster.
Step-by-step explanation:
When you plot y = 5x, you can trace a certain point to see which value is higher. When I plotted y = 5x and chose the point when x = 8, y = 40 for Kira, and for Lyric, at x = 8, y = 80. Since the y coordinate (distance) is higher, Lyric ran faster.
Lyric ran faster than Kira, since they were travelling a longer distance when comparing to Kira in the same period of time.
Step-by-step explanation:You may use the following logic to analyze this situation. Theoretically, the faster runner will have traveled a longer distance at any given point in time different than 0 when comparing to the other runner. Therefore, let's randomly pick a point in time to see who had traveled the longer distance.
The time we'll evaluate will be 4 seconds.
1. Evaluating the function to find Kira's traveled distance at 4 seconds.
For this, simply substitute the "x" by the number "4" in the given equation for Kira:
[tex]y=5(4)\\ \\y=20[/tex]
Conclusion: Kira had traveled a total distance of 20 yards, 4 seconds after starting the race.
2. Evaluating the function to find Lyric's traveled distance at 4 seconds.
To evaluate the graph, we'll have to draw a line where x=4 sits and then find the value of "y" the function returns. Check the attached images in order to see this process.
Conclusion: Lyric had traveled a total distance of 40 yards, 4 seconds after starting the race.
3. General conclusion.
After 4 seconds Kira traveled 20 yards;
After 4 seconds Lyric traveled 40 yards.
Conclusion: Lyric ran faster than Kira, since they were travelling a longer distance when comparing to Kira in the same period of time.

10. The table represents the relationship between the base length and the height of some parallelograms, Both measurements are in inches. What is the relationship between the base length and height of these parallelograms?
The relation between base length and height is: f(x) = 48/x
What is parallelogram?
A parallelogram is a straightforward quadrilateral in Euclidean geometry that has two pairs of parallel sides. A parallelogram has opposite sides that are facing one another and opposite angles that are of equal size.
By the values given in the table, for base length and height of the parallelograms, you can notice that base length increases 1 units, so you have 1, 2, 3, 4, 5.
For height you can notice that while base length increase 1 unit, height decreases by a factor of 1/x, just as follow:
1 - 48
2 - 24
3 - 16
4 - 12
5 - 8
The relation between base length and height is:
f(x) = 48/x
where f(x) is the height and x is the base length. In fact, you have:
f(1) = 48/1 = 48
f(2) = 48/2 = 24
f(3) = 48/3 = 16
f(4) = 48/4 = 12
Hence, the relation between base length and height is: f(x) = 48/x.

Hint: Use S = a1/ 1-r and remember that |r| must be less than 1.
If the distances form a geometric sequence, the total distance Mr. Meyering jumps if he completes infinitely many jumps is equal to 40 inches.
What is a geometric sequence?In Mathematics, a geometric sequence can be defined as a series of real and natural numbers that are calculated by multiplying the next number by the same number (common ratio) each time.
Mathematically, the sum of an infinite geometric sequence can be calculated by using this mathematical expression:
S = a₁/(1 - r)
Where:
S represents the sum of an infinite geometric sequence.r represents the common ratio or constant ratio.a is the first term of a geometric sequence.How to determine the total distance Mr. Meyering jumps?First of all, we would determine the common ratio between the distances he jumped as follows;
Common ratio, r = a₂/a₁
Common ratio, r = 10/20
Common ratio, r = 0.5.
For the total distance, we have;
S = a₁/(1 - r)

m = 2/5, and since slope is rise over run (distance traveled in y axis over distance traveled in x axis) and it is positive, your next point is 2 up and 5 right, which is (5,5). You could also place a point at (-2,-2).

If 3x – y = 5 and 2x + y = 15 then evaluation of x^2 + 2y is equal to 72.
What is evaluation ?
Finding the value of an algebraic expression when a given number is used to replace a variable is known as evaluating the expression. When evaluating an expression, we change the variable in the expression to the given number and then use the order of operations to simplify the expression.
