Find the simplified quotient.
y^2+y/ y^2-2y/ 4y+4/ y^2-4y+4
Can someone show me the work for this answer please
Answer:
yes the first one is the correct answer
We can see here that the simplified quotient is Option A: y(y+1)/y(y−2) × [(y−2) (y−2)]/4(y+1)
What is quotient?In mathematics, the term "quotient" refers to the result of dividing one quantity (the dividend) by another quantity (the divisor). It represents the whole number or fraction obtained as a result of the division operation.
To find the simplified quotient, we need to follow the steps for dividing fractions:
Step 1: Invert the divisor (the fraction that follows the division sign) and convert the division operation to multiplication.
Step 2: Simplify the resulting fraction by canceling out any common factors in the numerator and denominator.
The given expression is:
(y² + y) / (y² − 2y) ÷ (4y+4) / (y² −4y + 4)
Step 1: Invert the divisor and convert division to multiplication:
(y² + y) / (y² − 2y) × (y² −4y + 4) / (4y+4)
Step 2: Simplify the resulting fraction:
Now, let's factor the expressions in the numerators and denominators:
y(y + 1) / y(y - 2) × (y−2)² / 4(y + 1)
= y(y+1)/y(y−2) × [(y−2) (y−2)]/4(y+1)

5. Look at the diagram below. Indicate whether the angles below are
adjacent or vertical.
a <1 and <2
b. <3 and <4
C. <2 and <4
d. <1 and <3
Answer:
a. adjacent
b. adjacent
c. vertical
d. vertical
Step-by-step explanation:
Adjacent angles share a side; vertical angles do not. Vertical angles share a vertex and have sides that are opposite rays.
In the diagram, adjacent angles are sequentially numbered, so numbers that differ by 1 (or 3) are adjacent angles.
Vertical angles are not adjacent, so will have angle numbers that differ by 2.
adjacent: (a) and (b) . . . angles 1&2, 3&4
vertical: (c) and (d) . . . angles 2&4, 1&3
Which graph is that of the inequality shown below?
All answer choices show the boundary line going through (0,-2) and (2,2). This is because y = 2x-2 goes through these two points. We make the boundary line a dashed line to indicate that solution points are not found on the boundary (because there is no "or equal to" portion in the inequality sign).
The shading is below the boundary line because of the "less than" sign. Any solution point (x,y) will have its y coordinate smaller than the y coordinate of points on the boundary line. So if (a,b) is on the boundary, then (a,c) is a solution where c < b.
In summary, the graph has a dashed boundary line and the shading is below the boundary

plssssssssssssssssssssss help Six friends, four boys and two girls, went to a movie theater. They wanted to sit in a way so no girl sits on either first or last chair. How many such arrangements are possible?
Answer:
672 ways
Step-by-step explanation:
The total number of ways the friends were supposed to sit without restrictions would have been = 6!
= 720 possible ways.
If the girs should sit on the first or last sit
The possible arrangement= 2!4!
= 2*24
= 48
But now the two girls should be arranged in such a way that the don't sit on either the first or the last chair.
So the possible way now is= way without restriction - way if the girls are to sit at either first or last sit
= 720-48
= 672

672.
Step-by-step explanation:
Currently patrons at the library speak at an average of 64 decibels. Will this average decline after the installation of a new computer plug in station? After the plug in station was built, the librarian randomly recorded 47 people speaking at the library. Their average decibel level was 63.2 and their standard deviation was 5. What can be concluded at the the α α = 0.05 level of significance?
Answer:
The conclusion is that the average level of decibel at the library has changed since the installation of a new computer plug
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 64[/tex]
The sample size is [tex]n = 47[/tex]
The sample mean is [tex]\= x = 63.2[/tex]
The sample standard deviation is [tex]\sigma = 5[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The Null Hypothesis is
[tex]H_o : \mu = 64[/tex]
The Alternative Hypothesis is
[tex]H_a : \mu \ne 64[/tex]
The test statistics is mathematically evaluated as
[tex]t = \frac{\= x - \mu }{\frac{\sigma }{\sqrt{n} } }[/tex]
substituting values
[tex]t = \frac{63.1 - 64 }{\frac{5 }{\sqrt{47} } }[/tex]
[tex]t = -1.234[/tex]
The negative sign show that this is a left-tail test
Now the critical value of the level of significance obtained from the critical values table is
[tex]z_{0.05} = 1.645[/tex]
Now comparing the critical value of the [tex]\alpha[/tex] and the test statistics we see that critical value is greater than the test statistic which implies that the null hypothesis is rejected.
The conclusion is that the average level of decibel at the library has changed since the installation of a new computer plug

10. The population of India is 1.353 billion, and expected to grow at the rate of one percent
annually for the forseeable future. Assuming population continues to grow at the same percent
rate, how long until the population reaches 2 billion people? Give your answer to the nearest
year. (4 minutes)
Answer:
39 years
Step-by-step explanation:
Adapt the formula A = P(1 + r)^n, letting P represent the original population, r the growth rate as a decimal fraction, and n the number of years.
Solve this for n:
2 billion = (1.353 billion)(1 + 0.01)^n
After simplification, we have:
2
--------- = 1.01^n
1.353
Taking the log of both sides, we get:
log 2 - log 1.353 = n log 1.01, or
log 2 - log 1.353 0.1697
------------------------ = -------------- = 39 years (rounded off from 39.28)

Which of the following is an even function? (A) g(x)=5x+2 (B) g(x)=x (C) g(x)= x 2 (D) g(x)=x3 (E) g(x)=−|x|
Answer:
(C) g(x) = x² and (E) g(x) = -|x|Step-by-step explanation:
If f(x) is an even function, then f(-x) = f(x).
(A)
g(x) = 5x + 2
g(-x) = 5(-x) + 2 = -5x + 2
g(-x) ≠ g(x)
(B)
g(x) = g(x) = x
g(-x) = -x
g(-x) ≠ g(x)
(C)
g(x) = x²
g(-x) = (-x)² = (-1x)² = (-1)²(x)² = x²
g(-x) = g(x)
(D)
g(x) = x³
g(-x) = (-x)³ = (-1x)³ = (-1)³(x)³ = -1x³ = -x³
g(-x) ≠ g(x)
(E)
g(x) = -|x|
g(-x) = -|-x| = -|-1x| = -(|-1|)(|x|) = -1|x| = -|x|
g(-x) = g(x)

20% of city employees ride the bus to work. This is up 10% from last year. What percent of employees rode the bus to work last year?
Answer:
18.18% of employees rode the bus to work last year
Step-by-step explanation:
This question can be solved using a rule of three.
Last year, a proportion of x employees riding the bus was 100% = 1.
This year, 20% = 0.2 ride the bus, which is 100 + 10 = 110% = 1.1 of last year.
So
0.2 - 1.1
x - 1

An election ballot asks voters to select six city commissioners from a group of 24 candidates in how many ways can this be done? Six city commissioners can be selected from a group of 24 candidates in blank different ways
Answer:
134,596 diffrent ways.
Step-by-step explanation:
Combination has to do with selection. When n object is to be selected from n objects, this can be achieved using the combination formula as shown; \
nCr = n!/(n-r)!r!
If an election ballot asks voters to select six city commissioners from a group of 24 candidates, then the selection can be done in 24C6 different ways.
Applying the formula above:
24C6 = 24!/(24-6)!6!
24C6 = 24!/18!6!
24C6 = 24*23*22*21*20*19*18!/18!*6*5*4*3*2
24C6 = 24*23*22*21*20*19/24*30
24C6 = 23*22*21*20*19/30
24C6 = 134,596 different ways.
Hence, Six city commissioners can be selected from a group of 24 candidates in 134,596 different ways
