Drag the movable points to form a system of linear equations with no solutions

The sequence {12,5, -2, -9,-16...) can be defined as a sequence with a0 = 12 and aₙ = 19 - 7n.

Also, the sequence {1, 4, 9, 16, 25,...} can be defined as increasing and unbounded.

A sequence is a list of numbers (or elements) that exhibits a particular pattern. For example, Olivia has been offered a job with a monthly salary of $1000 and an annual increment of $500. Can you calculate her monthly salary in the first three years? It will be $1000, $1500, and $2000. Observe that Olivia's salary over a number of years forms a sequence as they follow a pattern where the numbers increase by $500 every time. The order of a sequence can be either in ascending order or in descending order.

1] We are given a sequence: {12,5, -2, -9,-16...)

This sequence is an Arithmetic progression with the first term a = 12 and common difference d = -7.

2] The given sequence is {1, 4, 9, 16, 25,...}

The general term for this sequence is aₙ = n²

This sequence can be defined as increasing and unbounded.

Thus, the sequence {12,5, -2, -9,-16...) can be defined as a sequence with a0 = 12 and aₙ = 19 - 7n.

Also, the sequence {1, 4, 9, 16, 25,...} can be defined as increasing and unbounded.

Step-by-step explanation:

the Pizza Hut driver has a circle with a radius of 20 which is the area he can cover. you're looking for the area of the circle, and the formula for the area of a circle is pi * r * r

If you substitute, you have 3.14*20*20, which is 1256

The equivalent ratios are given as follows:

Hence the coordinates are given as follows:

As the constant of the proportional relationship is of 3, starting from the origin, the points are plotted always moving one unit right (x) and three units up (y).

A proportional relationship is defined as follows:

y = kx.

In which k is the constant of proportionality.

Then the constant is obtained as follows:

k = y/x.

For this problem, the constant is given as follows:

In this case, the limit is 0, so the series is indeed convergent.

The Root Test is used to determine the convergence or divergence of a series. and it is used the Root Test, we start by finding the nth root of each term in the series.

In this case, the series is

=> [∞] n = 1 4 1 1 n n²,

so we calculate the nth root of each term:

[tex]= > (1/n^{2} )^{1/n}[/tex]

Then, we take the limit of this expression as n approaches infinity, to find the value of the root.

If this limit is less than 1, the series is convergent. If the limit is greater than or equal to 1, the series is divergent.

In this case, the limit of [tex](1/n^{2} )^{1/n}[/tex] as n approaches infinity is 0, which is less than 1. This means that the series is convergent.

To confirm this, we can evaluate the limit of the absolute value of each term as n approaches infinity, using the formula

=> lim n → [∞] n |aⁿ|.

If this limit is finite, then the series is convergent.

The formula for the probability that exactly k balls are red when a collection of n < min{m, n - m} balls is taken out at random without replacement is given by:P(k red balls) = (C(m, k) * C(n - m, n - k)) / C(n, n) = (m! / (k! * (m - k)!) * (n - m)! / ((n - k)! * (n - m - n + k)!)) / (n! / (n! * 0!)) = (m! * (n - m)!) / (k! * (m - k)! * (n - k)! * n!).

Given n balls, m of which are red and n - m are blue, if a collection of n < min{m, n - m} balls is taken out at random without replacement, the probability that exactly k balls are red can be calculated using the Hypergeometric Distribution. The formula for the probability that exactly k balls are red is given by: P(k red balls) = (C(m, k) * C(n - m, n - k)) / C(n, n)

where C(n, k) denotes the number of combinations of n things taken k at a time, and is given by: C(n, k) = n! / (k! * (n - k)!).

Therefore, the formula for the probability that exactly k balls are red when a collection of n < min{m, n - m} balls is taken out at random without replacement is given by:

P(k red balls) = (C(m, k) * C(n - m, n - k)) / C(n, n) = (m! / (k! * (m - k)!) * (n - m)! / ((n - k)! * (n - m - n + k)!)) / (n! / (n! * 0!)) = (m! * (n - m)!) / (k! * (m - k)! * (n - k)! * n!).

Blinding refers to the nondisclosure of the treatment an experimental unit is receiving in a controlled experiment.

Blinding is a technique used in experimental design to reduce bias and improve the validity of results. It refers to the practice of not revealing to the experimental units (e.g., participants, animals) or the experimenters which treatment they are receiving in a controlled experiment. Blinding is used to eliminate potential sources of bias that might influence the results of the experiment.

For example, if the participants are aware of the treatment they are receiving, they might behave differently and affect the results. Similarly, experimenters might unconsciously treat participants differently based on their knowledge of the treatment, which could also affect the results.

Blinding is the practice of keeping the therapy that an experimental unit is getting a secret. In a single-blind experiment, the experimental unit (also known as the subject) is kept in the dark regarding the therapy that he or she is getting.

For the population model DP/dt = 0.3(1-P/200)(P/50-1)P describes how the population changes over time based on the value of P.

a) The population is in equilibrium at P = 0 and P = 200,

b) increasing for values of P between 50 and 200, and

c) decreasing for values of P between 0 and 50 and values of P greater than 200.

The population model

=> DP/dt = 0.3(1-P/200)(P/50-1)P

is a mathematical expression that describes the change in population size over time.

In this model, P(t) represents the population at time t and the rate of change of the population, DP/dt, is a function of P.

The population is in equilibrium when the rate of change is zero, meaning the population is neither growing nor declining. To find the equilibrium population, we set DP/dt = 0 and solve for P. In this case, we have:

=> 0.3(1-P/200)(P/50-1)P = 0

Solving for P, we find two solutions: P = 0 and P = 200. These represent the minimum and maximum populations, respectively.

The population is increasing when the rate of change is positive, meaning the population is growing.

If DP/dt > 0, then the population is increasing, and if DP/dt < 0, then the population is decreasing.

In this case, we have:

=> DP/dt = 0.3(1-P/200)(P/50-1)P

To simplify, we can write:

=> DP/dt = 0.3(P/50-1)(P/200-1)P

=> (P/50-1)(P/200-1) > 0.

This occurs when 50 < P < 200.

Therefore, the population is increasing for values of P between 50 and 200.

The population is decreasing when the rate of change is negative, meaning the population is declining.

If DP/dt > 0, then the population is increasing, and if DP/dt < 0, then the population is decreasing.

In this case, we have:

DP/dt = 0.3(1-P/200)(P/50-1)P

To simplify, we can write:

DP/dt = 0.3(P/50-1)(P/200-1)P

Since the sign of P is positive, the sign of DP/dt is negative for all values of P where

=> (P/50-1)(P/200-1) < 0.

Therefore, the population is decreasing for values of P between 0 and 50 and values of P greater than 200.
