we have a room full of n people. any given pair of people are either friends or strangers. in this room, alex is considered the most popular because he has k friends, and no other person in the room has more than k friends. prove that we can find a group with at least n k 1 people such that no two members of the group are friends.
a group with at least n k 1 people such that no two members of the group are friends,We will prove this statement by inductive hypothesis.
Base Case: If n=k+1, then we can easily find a group with nk1 people such that no two members of the group are friends. We simply select the k+1 people in the room, excluding Alex. Since Alex has k friends, and no other person in the room has more than k friends, it follows that none of these k+1 people are friends.
Inductive Step: Assume that the statement is true for n=k+1. Now we must show that it is true for n=k+2.
We can select a group of k+1 people from the room, again excluding Alex. By the inductive hypothesis, we know that no two members of this group are friends. Now, we select the remaining person in the room, and add them to the group. This person cannot be friends with any of the members of the group, since Alex has k friends and no other person in the room has more than k friends. Therefore, the group we have formed has at least nk1 people, and no two members of the group are friends.
Therefore, by induction, we have proved that we can find a group with at least nk1 people such that no two members of the group are friends.

consider the functions given below. P(x)= 2/3x-1 Q(x)= 6/-3x+2 Match the expression with its simplified form
Answer:
P/Q = (-3x +2)/(3(3x -1))
PQ = 12/((3x -1)(-3x +2))
Step-by-step explanation:
You want the quotient and product of P(x) = 2/(3x -1) and Q(x) = 6/(-3x +2).
QuotientThe quotient is found by multiplying by the inverse of the denominator:
[tex]P(x)\div Q(x)=\left(\dfrac{2}{3x-1}\right)\div\left(\dfrac{6}{-3x+2}\right)=\left(\dfrac{2}{3x-1}\right)\times\left(\dfrac{-3x+2}{6}\right)\\\\\\\dfrac{2(-3x+2)}{6(3x-1)}=\boxed{\dfrac{-3x+2}{3(3x-1)}}[/tex]
ProductAs with multiplying any fractions, the numerator is the product of the numerators, and the denominator is the product of the denominators.
[tex]P(x)\times Q(x)=\left(\dfrac{2}{3x-1}\right)\times\left(\dfrac{6}{-3x+2}\right)=\dfrac{2\cdot 6}{(3x-1)(-3+2)}\\\\\\=\boxed{\dfrac{12}{(3x-1)(-3x+2)}}[/tex]

Find the angle between the vectors. (First find an exact expression and then approximate to the nearest degree.) a = 71 - 2j + k, b = 3i - k exact approximate
Details scalcets,
a) If u is unit vector , then, ⃗u.⃗v = 1/2 and ⃗u.⃗w = - 1/2 where v and w also unit vectors.
b) Exact value of angle between the vectors is 34.3803442 and Approximation value, 34.4..
c) Exact value of the angle between the vectors, a = 71 - 2j + k, b = 3i - k is 30.60889766 ~ 30.61 (approximation value).
What is Unit vector ?In mathematics, a unit vector is defined as a normed vector space is a vector of length one.
a) If u is a unit vector , we have to calculate ⃗u.⃗v and ⃗u.⃗w where v and w are also unit vectors.
We know that, Angle between two vectors θ is
Cosθ = u⃗ .⃗v/|u| |v|
=> cos 60° |u| |v| = ⃗u.⃗v
=> ⃗u.⃗v = 1/2(1)(1) = 1/2
Also, Cosθ = ⃗u.⃗v/|u| |w|
=> Cosθ |u| |w| = ⃗u.⃗w
=> ⃗u.⃗w = cos 120° (1)(1)
=> ⃗u.⃗w = -1/2
So, ⃗u.⃗v = 1/2 and ⃗u.⃗w = - 1/2
b) We have, a = (7,2), b = (3,-1)
Cosθ = a.b/|a| |b|
|a| = √(7)²+ (2)² = √49+4 = √53
|b| = √(3)²+ (-1)²= √9+1 = √10
a.b = 7×3 - 2×1 = 21 - 2 = 19
so, Cos θ = 19/√10 (√53) = 19/√530
=> θ = Cos⁻¹( 19/√530)
=> θ = 34.3803442 ~ 34.4
c) We have, a = 7i - 2j + k, b = 3i - k
Cos θ = a.b/|a| |b|
|a| = √(7)² + (-2)² +(1)² = √49+4+1 = √54
|b| = √(3)²+ 0 +(-1)² = √9+1 = √10
a.b = (7i - 2j + k).(3i - k) = 21 -0 - 1 = 20
Cosθ = 20/√10√54 = 20/√540
θ = cos⁻¹(20/√540) = 30.60889766 ~ 30.61

A line passes through the point (-4,8) and has a slope of -6 .
Write an equation in slope-intercept form for this line.
Answer:
y = (-6)*x - 16
Step-by-step explanation:
The slope-intercept form of a line is given by the equation:
y = mx + b
where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).
In this case, the line passes through the point (-4,8) and has a slope of -6, so we can plug these values into the equation to find the y-intercept:
y = (-6)*x + b
We know that the line passes through the point (-4,8), so we can substitute these values into the equation to solve for b:
8 = (-6)*(-4) + b
8 = 24 + b
b = -16
Therefore, the equation of the line in slope-intercept form is:
y = (-6)*x - 16

The value of x is $53.34 but cannot exceed $115, while the value of y can be as low as $160 but cannot exceed $345.
What is an inequality?Relationships that compare two numbers or other mathematical expressions in an unequal manner are known in mathematics as inequalities. The most common use is to compare the magnitude of two numbers on a number line.
The answer to the query is
Diane will make a charitable donation "up to $460," which indicates it can be less than or equal to 460 but not more. Then,
$460 donated to charity (max)
plus $160 for educational (160 being the minimum)
Education is also stated to be three times (or greater) than City.
If x represents the city and y represents education, then
x + y = 460 . And we are aware that y 3x.
x + 3x = 4x = 460
x = 115.
This implies that she will contribute $345 to Educational when she donates 3 times (or $115) to City. The maximum value is these.
She won't provide more than $460.
Earlier, Educational had a minimal need.
When y = 160,
x equals y/3,
=> x = 160/3 = $53.34. She so gave 213.34 dollars, which is still less than $460.
As a result, x (which is City) might be anywhere between $53.34 and $115.
x, which stands for educational, might be as little as $160 or as high as $345.

64 = 20 + 0.50x
subtract 20 from both sides of the equation'
64 - 20 = 20 - 20 + 0.50x
44 = 0.50x
divide both sides by 0.50
Therefore,
44 / 0.50 = 0.50x / 0.50

Which of the following functions is graphed below?
The function of the line and parabola shown in the graph is x + 6 ≤ 1 and x² + 3 > 1 respectively, so, option A is correct.
What is function?Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.
Given:
The graph of the function,
Calculate the equation of the line which is passing through (-6, 0) and (0, 5) as shown below,
y - 5 = 5 - 0 / 0 - (-6) (x - 0)
y - 5 = 5 / 6 x
6y - 30 = 5x
And the equation of the parabola can be written as,
x² + 3 = 0
From the graph, it can be seen that the solution of the line is where the line graph and parabola graph can meet,
Thus, the line will be x + 6 ≤ 1 and x² + 3 > 1.

Which of the following normal curves corresponds to P(X> 37)? OA. OC. 37 50 37 50 37 50 PX-37)-□ (Round to four decimal places as needed.)
The normal curve that corresponds to P (X > 37) is C, as the shaded area corresponds to the probability of 0.4207.
The normal curve is a bell-shaped curve which is used to represent a continuous probability distribution. It is used to represent the probability of a random variable X, which is normally distributed with mean μ and standard deviation σ. In this case, we have X with mean μ = 50 and standard deviation σ = 7. To compute the probability P(X > 37), we first draw a normal curve with the area corresponding to the probability shaded. Then, we can look up the area from the table of areas under the normal curve. The area corresponds to 0.4207, and the normal curve that corresponds to this probability is C, as the shaded area corresponds to the probability of 0.4207. This normal curve has the mean of 50 and the standard deviation of 7, with the area beyond 37 shaded.
P(X > 37)
= 1 - P(X ≤ 37)
= 1 - 0.4207
= 0.5793

Find a power series representation for the function; find the interval of convergence. (Give your power series representation centered at x = 0.)
f(x)= 1/(1-9x)
sum from n=0 to infinity [?] provided |x| < [?]
The power series representation for the given function is:
1+ 9x + (9x)² + (9x)³ + .... (9x)ⁿ (where 0 ≤ n ≤ ∞).
What is the power series?
Power series is a sum of terms of the general form aₙ(x-a)ⁿ. Whether the series converges or diverges, and the value it converges to, depends on the chosen x-value, which makes power series a function.
Let u = 9x.
Return to the series above and replace each u with a 9x directly:
Where 0 n , 1 + 9x + (9x) 2 + (9x) 3 +.... (9x) n
Here, the interval of convergence is easily found. It follows that
|9x| 1 -1/9 x 1/9 because we know that geometric series must have | u | = 1
Finally, we may leverage the fact that geometric series have a sum to get the sum: S = a / (1 - u).
Here, u = 9x and a = 1
Therefore, the total is simply S = 1 /(1 - 9x).
Any sum can be calculated provided x is between -1/9 and x and less than 1/9.
Hence, The power series representation for the given function is:
1+ 9x + (9x)² + (9x)³ + .... (9x)ⁿ (where 0 ≤ n ≤ ∞).
