Final answer:
To factor quadratic expressions in general, we can use the AC Method, which involves breaking down the middle term and finding two numbers that multiply to give a certain product and add up to the coefficient of the middle term.
Explanation:
To factor quadratic expressions in general, we can use the method known as the AC Method. This method involves breaking down the middle term of the quadratic expression and finding two numbers that multiply to give a certain product (the product of the coefficient of the leading term and the constant term) and add up to the coefficient of the middle term. Once we find these two numbers, we can rewrite the quadratic expression as a product of two binomials.
For example, let's say we have the quadratic expression [tex]2x^2[/tex] + 5x + 3. The product of the leading coefficient (2) and the constant term (3) is 6. We need to find two numbers that multiply to 6 and add up to the coefficient of the middle term (5). The numbers 3 and 2 fit this criteria. Therefore, we can rewrite the quadratic expression as (2x + 3)(x + 1).
Note that if the quadratic expression cannot be factored using this method, it is considered a prime polynomial and cannot be factored further.

If f(x)=2x-4, find f(q+1)
please show your work!
Answers
If the function f(x) = 2x-4, the function f(q + 1) = 2q - 2
What is a function?A function is a mathematical equation that shows the relationship between two variables.
Since if f(x)=2x-4, to find f(q+1), we proceed as follows.
Since we have the function f(x) = 2x - 4, and we want to find f(q + 1). To find the function f(q + 1), we substitute x = q + 1 into the equation. so, we have that
f(x) = 2x - 4
When x = q + 1, we have that
f(x) = 2x - 4
f(q + 1) = 2(q + 1) - 4
Expanding the brackets, we have that
f(q + 1) = 2q + 2 - 4
= 2q - 2
So, f(q + 1) = 2q - 2

A researcher is interested in estimating the average salary of police officers in a large city. She wants to be 99% confident that her estimate is correct. If the standard deviation is $1050, how large a sample is needed to get the desired information and to be accurate within $200?
Answers
σ = $1050, ppulatin standard deviation
99% confidence interval
Accuracy = +/- $200
The accuracy is given by
z*(σ/√n)
where
z* = 2.576 for 99% confidence level (from tables)
n = sample size
Therefore
2.576(1050/√n) = 200
√n = (2.576*1050)/200 = 13.524
n = 182.9
Answer: The sample size is 183

Answers
n*2 = 2n [and n packages containing two pens each]
So the total number of pens that he bought is 2n+5
This is because you know how many packages of 5 pens he bought which is 1. So that stays the same. you are trying to figure out how many packages of 2 pens he bought so that is a variable. so to find the total number of pens it is 2n+5.

Answers
Answer: The value of k is 2.
Step-by-step explanation:
Given : The graph of [tex]f(x)=(0.5)x[/tex] is replaced by the graph of [tex]g(x)=0.5)x-k.[/tex]
If g(x) is obtained by shifting f(x) down by 2 units, then [tex]g(x)=(0.5)-2[/tex]
[since f(x)shifted down down by 2 , so only the value of dependent variable effect]
When we compare both functions of g(x), we found that k=2.
Hence, the value of k is 2.
The value of [tex]k[/tex] is 2.
The following information should be considered:
when [tex]g(x)[/tex] is obtained by shifting f(x) fall by 2 units so [tex]g(x) = (0.5) - 2.[/tex]Since [tex]f(x)[/tex] shifted down by 2 so there is the effect on the dependent variable. Now at the time of comparing both functions of g(x) the k should be 2.Learn more: brainly.com/question/17429689

Answers
Part A:(This table is a three by three table, with the first top two sections being liked apple juice and didn't like apple juice, and the first left two sections being liked orange juice and didn't like orange juice. The end sections are totals.)
No 27 45 72
Total 35 55 100
Part B:(What percentage of the total people did not like either apple or orange juice?)
25 people did not like either apple or orange juice so 25/100 is 25%.
Part C:(Do the people surveyed have more dislike for apple juice than orange juice? Justify your answer.)
There were a total of 28 people that liked orange juice against a total of 35 people that liked apple juice, so it is safe to say that out of the 100 surveyed there was more dislike for orange juice than apple juice.
Answer:
Part A: A = 8
B = 20
C = 28
D = 35
E = 37
F = 72
G = 43
H = 57
I = 200
Part B: 18.5%
Part C:
D = People who do not like Orange Juice
B = People who do not like Apple Juice
I use the values of B and D because these are the values that represent dislike for that juice, and also because adding them together creates a value for not liking either juice.
D = 35
B = 20
So there is a greater dislike for Orange Juice.

A wire that is 22 feet long connects the top of a pole to the ground. The wire is attached to the ground at a point that is 10 feet from the base of the pole.
What is the height of the pole? Round to the nearest hundredth.
12.00 feet
19.60 feet
24.17 feet
38.40 feet
Answers
Solution:
Length of wire = 22 feet =AB
Distance between the point where wire is attached to the ground from the point on the ground where pole is fixed= 10 feet=OB
In Right Δ O A B
By Using pythagoras theorem
O A² + OB² = AB²
O A² +10²= 22²
O A²= 484 - 100
O A²= 384
O A= √384= 19.60 (Approximately)
So, the height of pole to nearest hundredth = 19.60 feet
The height of the pole is 19.60 ft
The situation forms a right angle triangle.
Right angle triangleRight angle triangle have one of its sides as 90 degree.
The length of the wire is the hypotenuse of the triangle formed.
The distance of the wire attached to the ground to the base of the pole is the adjacent side of the triangle.
The height of the pole can be found using Pythagoras theorem.
c² = a² + b²
22² - 10² = b²
b² = 484 - 100
b = √384
b = 19.5959179423
b = 19.60 ft

classify the following triangle . check all that apply
Answers
Two equal sides ⇒ Isosceles
Answer:
Option (a) and (d) is correct.
The given triangle is obtuse and isosceles.
Step-by-step explanation:
Given : A triangle with measure of one angle is 120° and two legs of the triangle are given equal in length.
We will have to choose the correct classification for the given triangle.
For a triangle if the measure of one the angles is
1) less than 90 then it is acute triangle ,
2) equal to 90 then right triangle
3) greater to 90 then obtuse triangle
Since the measure of one angle of the triangle is 120° > 90° Thus, the given triangle is obtuse.
For a triangle if all the three sides are equal then it is equilateral triangle, if two sides are equal then it is isosceles and if no side is equal then it is scalene.
Since, for the given triangle, the two legs of the triangle are given equal in length so it is an isosceles triangle.
Thus, the given triangle is obtuse and isosceles.
