The time required for the account balance to reach $8000 is 26.187 months(using compund interest), which is approximately equal to 2.18 years, after rounding to two decimal places.
Given,
Homer invests $3000 in an account paying 10% interest compounded monthly.
The interest rate, r = 10% per annum = 10/12% per month = 0.1/12
The amount invested, P = $3000.
The final amount, A = $8000
We need to find the time required for the account balance to reach $8000.
Let n be the number of months required to reach the balance of $8000.
Using the formula for compound interest,
we can calculate the future value of the investment in n months.
It is given by:A = P(1 + r/n)^(n*t)
Where, P is the principal or investment,
r is the annual interest rate,
t is the number of years,
and n is the number of times the interest is compounded per year.
Substituting the given values in the above formula, we get:
8000 = 3000(1 + 0.1/12)^(n)t
Simplifying this equation, we get:
(1 + 0.1/12)^(n)t = 8/3
Taking the log of both sides, we get:
n*t * log(1 + 0.1/12) = log(8/3)
Dividing both sides by log(1 + 0.1/12), we get:
n*t = log(8/3) / log(1 + 0.1/12)
Solving for n, we get:
n = (log(8/3) / log(1 + 0.1/12)) / t
Let us assume t = 1 year, and then we can calculate n as:
n = (log(8/3) / log(1 + 0.1/12)) / t
= (log(8/3) / log(1 + 0.1/12)) / 1
= 26.187 (approx.)
Therefore, the time required for the account balance to reach $8000 is 26.187 months, which is approximately equal to 2.18 years, after rounding to two decimal places.

The remainder term can be written as:
R3(x) = (-1/384)*(x-4)^4/ξ^4
The Taylor's formula for the function f(x) = ln x, centered at x_0 = 4 with n = 3 is:
ln(x) = ln(4) + (x-4)/4 - (x-4)^2/32 + (x-4)^3/96 + R3(x)
where R3(x) is the remainder term given by:
R3(x) = (1/4^4) * fⁿ⁺¹(ξ)(x-4)^4
Here, fⁿ⁺¹(ξ) denotes the (n+1)th derivative of f evaluated at some point ξ between x and x_0.
In this case, since n=3, we have:
fⁿ⁺¹(ξ) = d⁴/dx⁴ [ln(x)] = -6/(ξ^4)
So the remainder term can be written as:
R3(x) = (-1/384)*(x-4)^4/ξ^4

absolute minimum value=
absolute maximum value=
The absolute minimum value = 4 and the absolute maximum value = 148.
Here is the solution to the given problem:
Given f(x) = 4x² - 8x + 8 on [0,7]. To find the absolute maximum and absolute minimum values of f on the given interval, we will have to follow the following steps.
Step 1: Differentiate f(x) with respect to x to get f'(x)4x² - 8x + 8f'(x) = 0On solving f'(x) = 0, we get the critical values of f, as follows:x = 1 and x = 2.
Step 2: Classify the critical values of f(x) in the interval [0, 7]We have two critical points x = 1 and x = 2.Now we will check the values of f(0), f(1), f(2) and f(7) to determine the absolute maximum and absolute minimum values of f(x) on the given interval [0,7].
Step 3: Check the values of f(0), f(1), f(2) and f(7).
For x = 0, f(0) = 8.
For x = 1, f(1) = 4 - 8 + 8 = 4.
For x = 2, f(2) = 16 - 16 + 8 = 8.
For x = 7, f(7) = 4(49) - 8(7) + 8 = 196 - 56 + 8 = 148.
So the absolute minimum value of f on [0, 7] is 4 and the absolute maximum value of f on [0, 7] is 148.Therefore, the absolute minimum value = 4 and the absolute maximum value = 148.

The cost of a rug that is 9 feet wide, according to the given function f(x) = 215(2x^2 - 4x - 6), is $655. Which can be found by using algebraic equation. Therefore, the correct answer is D.
To find the cost of a rug that is 9 feet wide, we substitute x = 9 into the given function f(x) = 215(2x^2 - 4x - 6). Plugging in x = 9, we have f(9) = 215(2(9)^2 - 4(9) - 6). Simplifying this expression, we get f(9) = 215(162 - 36 - 6) = 215(120) = $25800.
Therefore, the cost of a rug that is 9 feet wide is $25800. However, we need to select the answer in dollars, so we divide $25800 by 100 to convert it to dollars. Thus, the cost of a 9-foot wide rug is $258.Among the given answer choices, the closest one to $258 is option D, which is $655. Therefore, the correct answer is D.

8 x^{2}-30 x+12 The perimeter of a rectangle is 50 {~cm} . The length is 7 {~cm} more than the width. Find the dimensions of the rectangle (Length and Width)
To find the dimensions of the rectangle, we can set up a system of equations based on the given information. By considering the perimeter and the relationship between the length and width, we can solve for the dimensions of the rectangle.
Let's assume the width of the rectangle is represented by "w." According to the given information, the length is 7 cm more than the width, so we can represent the length as "w + 7." The perimeter of a rectangle is calculated by adding twice the length and twice the width, so we can set up the equation 2(w + 7) + 2w = 50 to represent the perimeter of 50 cm. Simplifying this equation, we have 2w + 14 + 2w = 50, which further simplifies to 4w + 14 = 50. By subtracting 14 from both sides of the equation, we find 4w = 36. Dividing both sides by 4, we get w = 9. Hence, the width of the rectangle is 9 cm.
To find the length, we substitute the value of the width (w = 9) into the expression for the length (w + 7), giving us a length of 16 cm. Therefore, the dimensions of the rectangle are 16 cm (length) and 9 cm (width).

The area of the normal distribution curve that is on the right-hand side of the vertical line is 0.8461.
We are required to find the area of the normal distribution curve which is on the right-hand side of the vertical line that is drawn through a normal distribution at z = -1.02.
We know that the total area under the normal distribution curve is 1. Also, the normal distribution curve is symmetric about the mean. Therefore, we can find the area to the right of the vertical line by finding the area to the left of the line and then subtracting it from 1.So, let's find the area to the left of the vertical line. We can use the standard normal distribution table to find this area. The table provides us with the area to the left of the z-value. z = -1.02
The area to the left of z = -1.02 is 0.1539.
Now, let's subtract this area from 1 to find the area to the right of the vertical line.
area = 1 - 0.1539= 0.8461
Therefore, the area of the normal distribution curve that is on the right-hand side of the vertical line is 0.8461.

The minimum sample size needed assuming that no prior information is available is 667. Hence, n = 667.
Here are the steps to calculate the minimum sample size needed assuming that no prior information is available:
Given that the researcher wishes to estimate, with 99% confidence, the population proportion of motor vehicle fatalities that were caused by alcohol-impaired driving, and his estimate must be accurate within 4% of the population proportion.
Now, to calculate the minimum sample size needed when there is no prior information available, we use the formula for the sample size for proportions;
n = (zα/2/ E)²P (1 - P)
where n is the minimum sample size, zα/2 is the z-score for the confidence level, E is the margin of error, and P is the estimated proportion of the population that has the attribute of interest.
Confidence level = 99%,
hence the corresponding z-score (zα/2) = 2.58
Margin of error (E) = 4%
= 0.04
P = 0.5 (assuming the worst-case scenario, where the proportion of interest is 50%, which gives the maximum value for the sample size)
Now, we can substitute the values in the formula;
n = (zα/2/ E)²P (1 - P)
n = (2.58/0.04)²(0.5)(0.5)
n = 666.42
The minimum sample size needed assuming that no prior information is available is 667. Hence, n = 667.

Triangle HKI is a right triangle with two congruent right angles, also known as an isosceles right triangle.
Since JK is a perpendicular bisector of HI and HI acts as a bisector of JK, we can conclude that HI and JK are perpendicular to each other and intersect at point L.
Given that JK, the perpendicular bisector of HI, goes through L and is twice the length of HI, we can label the length of HI as "x." Therefore, the length of JK would be "2x."
Now let's consider the triangle HKI.
Since HI is a bisector of JK, we can infer that angles HKI and IKH are congruent (they are the angles formed by the bisector HI).
Since HI is perpendicular to JK, we can also infer that angles HKI and IKH are right angles.
Therefore, triangle HKI is a right triangle with angles HKI and IKH being congruent right angles.

To find the product of -3i(7i-9), we need to apply the distributive property of multiplication over addition. Therefore, we have:
-3i(7i-9) = -3i x 7i - (-3i) x 9

use spherical coordinates. evaluate x2 dv, e where e is bounded by the xz-plane and the hemispheres y = 1 − x2 − z2 and y = 16 − x2 − z2
To evaluate x² dV over the region E bounded by the xz-plane and the hemispheres y = √16 − x² − z² and y = √25 − x² − z² using spherical coordinates, set up the triple integral as ∫∫∫ (r sin θ cos φ)² r² sin θ dr dθ dφ, with the limits of integration as 0 ≤ r ≤ √(16 - z²), 0 ≤ θ ≤ π/2, and 0 ≤ φ ≤ 2π.
To evaluate the integral x² dV using spherical coordinates, we first need to express the integral in terms of the spherical coordinate system. The differential volume element in spherical coordinates is given by dV = r² sin θ dr dθ dφ.
Since we want to find the integral over the region E, which is bounded by the xz-plane and the two hemispheres, we need to determine the limits of integration for the spherical coordinates.
The bounds for the other two spherical coordinates, r and φ, can be determined by considering the equations of the two hemispheres.
For the upper hemisphere, we have:
y = √(16 - x² - z²)
Setting y = 0, we can solve for r and z:
0 = √(16 - x² - z²)
Squaring both sides, we get:
0 = 16 - x² - z²
Rearranging the equation, we have:
x² + z² = 16
This represents the boundary of the upper hemisphere, so the limits for r and φ will be determined by this equation.
For the lower hemisphere, we have:
y = √(25 - x² - z²)
Setting y = 0, we can solve for r and z:
0 = √(25 - x² - z²)
Squaring both sides, we get:
0 = 25 - x² - z²
Rearranging the equation, we have:
x² + z² = 25
This represents the boundary of the lower hemisphere, so the limits for r and φ will be determined by this equation.
Using the spherical coordinate system, we can rewrite x² dV as (r sin θ cos φ)² r² sin θ dr dθ dφ.
Now, we can set up the integral:
∫∫∫ (r sin θ cos φ)² r² sin θ dr dθ dφ
The limits of integration are as follows:
0 ≤ r ≤ √(16 - z²)
0 ≤ θ ≤ π/2
0 ≤ φ ≤ 2π
By evaluating this triple integral, we can find the value of x² dV over the region E.

In the above code, `f_target(x)` is the target distribution that we want to simulate from.
Let `f_prop(x)` be the proposal distribution, which we have taken as a beta distribution with α=2, β=6.
The proposal density function can be written as:
f_prop(x) = x^(α-1) * (1-x)^(β-1) / B(α, β),
where B(α, β) is the beta function given by B(α, β) = Γ(α) * Γ(β) / Γ(α+β).
Then, c can be calculated as follows:
c = max(f_target(x) / f_prop(x)), 0 ≤ x ≤ 1.
Now, we can write a code to simulate the beta distribution using the accept-reject algorithm as follows:
python

import seaborn as sns

beta_prop = gamma(a) * gamma(b) / gamma(a+b)
p = x**(a-1) * (1-x)**(b-1)
return 1/beta_prop * p
c = f_target(0.5) / f_prop(0.5) # since f_target(0.5) is greater than f_prop(0.5)
def beta_simulate(n):

Suppose that researchers wanted a sufficiently large sample to estimate the probability of preferring the new drug to within 0.05, at confidence level 95%. If the true probability is 0.90, how large the sample size should be?
In a crossover trial comparing a new drug to a standard, all statistical tests and confidence intervals support the conclusion that the new drug is better. The required sample size is at least 692.
In a crossover trial comparing a new drug to a standard, π denotes the probability that the new one is judged better. In 20 independent observations, the new drug is better each time. The null and alternative hypotheses are H0: π = 0.5 and Ha: π ≠ 0.5.
a. The likelihood function is given by the formula: [tex]L(\pi|X=x) = (\pi)^{20} (1 - \pi)^0 = \pi^{20}.[/tex]. Thus, the likelihood function is a function of π alone, and we can simply maximize it to obtain the maximum likelihood estimate (MLE) of π as follows: [tex]\pi^{20} = argmax\pi L(\pi|X=x) = argmax\pi \pi^20[/tex]. Since the likelihood function is a monotonically increasing function of π for π in the interval [0, 1], it is maximized at π = 1. Therefore, the MLE of π is[tex]\pi^ = 1.[/tex]
b. To conduct a Wald test for the null hypothesis H0: π = 0.5, we use the test statistic:z = (π^ - 0.5) / sqrt(0.5 * 0.5 / 20) = (1 - 0.5) / 0.1581 = 3.1623The p-value for the test is P(|Z| > 3.1623) = 0.0016, which is less than the significance level of 0.05. Therefore, we reject the null hypothesis and conclude that there is sufficient evidence to suggest that the new drug is better than the standard. The 95% Wald confidence interval for π is given by: [tex]\pi^ \pm z\alpha /2 * \sqrt(\pi^ * (1 - \pi^) / n) = 1 \pm 1.96 * \sqrt(1 * (1 - 1) / 20) = (0.7944, 1.2056)[/tex]
c. To conduct a score test, we first need to calculate the score statistic: U = (d/dπ) log L(π|X=x) |π = [tex]\pi^ = 20 / \pi^ - 20 / (1 - \pi^) = 20 / 1 - 20 / 0 = $\infty$.[/tex]. The p-value for the test is P(U > ∞) = 0, which is less than the significance level of 0.05. Therefore, we reject the null hypothesis and conclude that there is sufficient evidence to suggest that the new drug is better than the standard. The 95% score confidence interval for π is given by: [tex]\pi^ \pm z\alpha /2 * \sqrt(1 / I(\pi^)) = 1 \pm 1.96 * \sqrt(1 / (20 * \pi^ * (1 - \pi^)))[/tex]
d. To conduct a likelihood-ratio test, we first need to calculate the likelihood-ratio statistic:
[tex]LR = -2 (log L(\pi^|X=x) - log L(\pi0|X=x)) = -2 (20 log \pi^ - 0 log 0.5 - 20 log (1 - \pi^) - 0 log 0.5) = -2 (20 log \pi^ + 20 log (1 - \pi^))[/tex]
The p-value for the test is P(LR > 20 log (0.05 / 0.95)) = 0.0016, which is less than the significance level of 0.05. Therefore, we reject the null hypothesis and conclude that there is sufficient evidence to suggest that the new drug is better than the standard. The likelihood-based 95% confidence interval for π is given by the set of values of π for which: LR ≤ 20 log (0.05 / 0.95)
e. To estimate the probability of preferring the new drug to within 0.05 at a confidence level of 95%, we need to find the sample size n such that: [tex]z\alpha /2 * \sqrt(\pi^ * (1 - \pi{^}) / n) ≤ 0.05[/tex], where zα/2 = 1.96 is the 97.5th percentile of the standard normal distribution, and π^ = 0.90 is the true probability of preferring the new drug.Solving for n, we get: [tex]n ≥ (z\alpha /2 / 0.05)^2 * \pi^ * (1 - \pi^) = (1.96 / 0.05)^2 * 0.90 * 0.10 = 691.2[/tex]. The required sample size is at least 692.

Solve the following equation: y^′ =3−(2y)/(x+5)
The general solution to the differential equation is:
y = {3 - 1/(K(x+5)^2), if y < 3;
3 + 1/(K(x+5)^2), if y > 3}
To solve the given differential equation:
y' = 3 - (2y)/(x+5)
We can write it in separated variables form by moving all y terms to one side and all x terms to the other:
(y/(3-y))dy = (2/(x+5))dx
Now, we can integrate both sides:
∫(y/(3-y))dy = ∫(2/(x+5))dx
Using substitution u = 3-y for the left-hand side integral, we get:
-∫(1/u)du = 2ln|x+5| + C1
where C1 is a constant of integration.
Simplifying, we get:
-ln|3-y| = 2ln|x+5| + C1
Taking the exponential of both sides, we get:
|3-y|^(-1) = e^(2ln|x+5|+C1) = e^(ln(x+5)^2+C1) = K(x+5)^2
where K is a positive constant of integration. We can simplify this expression further:
|3-y|^(-1) = K(x+5)^2
Multiplying both sides by |3-y|, we get:
1 = K(x+5)^2|3-y|
We can now consider two cases:
Case 1: 3 - y > 0, which means y < 3.
In this case, we can simplify the equation as follows:
1/(3-y) = K(x+5)^2
Solving for y, we get:
y = 3 - 1/(K(x+5)^2)
where K is a positive constant.
Case 2: 3 - y < 0, which means y > 3.
In this case, we have:
1/(y-3) = K(x+5)^2
Solving for y, we get:
y = 3 + 1/(K(x+5)^2)
where K is a positive constant.
Therefore, the general solution to the differential equation is:
y = {3 - 1/(K(x+5)^2), if y < 3;
3 + 1/(K(x+5)^2), if y > 3}
where K is a positive constant of integration.

a. {n ∈ N: n² - 4 ≥ 2}
To find the least element of this set, we need to find the smallest natural number that satisfies the given condition.
n² - 4 ≥ 2
n² ≥ 6
The smallest natural number that satisfies this inequality is n = 3, because 3² = 9 which is greater than or equal to 6. Therefore, the least element of the set is 3.

(2) Find a if a ∨ 4 = 17.
(3) Tinker to find a and b that make a ∨ b = 58.
(d) Jill says there are whole numbers a and b so that a ∨ b = 23. Either find a and b or make a careful argument why this is not possible.
(e) Will ∨ ever produce a negative output?
1) 2 ∨ 3 equals 13.
2)a can be either 1 or -1.
3)a = 7 and b = 3 satisfy the equation a ∨ b = 58.
d)it is not possible for a ∨ b to equal 23 using whole numbers.
e)∨ will never produce a negative output.
(1) To find 2 ∨ 3, we substitute the values into the given expression:
2 ∨ 3 = 2^2 + 3^2
= 4 + 9
= 13
Therefore, 2 ∨ 3 equals 13.
(2) To find a when a ∨ 4 = 17, we set up the equation and solve for a:
a ∨ 4 = 17
a^2 + 4^2 = 17
a^2 + 16 = 17
a^2 = 1
a = ±1
So, a can be either 1 or -1.
(3) To find a and b such that a ∨ b = 58, we set up the equation and solve for a and b:
a ∨ b = a^2 + b^2 = 58
Since we are dealing with whole numbers, we can use trial and error to find suitable values. One possible solution is a = 7 and b = 3:
7 ∨ 3 = 7^2 + 3^2 = 49 + 9 = 58
Therefore, a = 7 and b = 3 satisfy the equation a ∨ b = 58.
(d) Jill's claim that there exist whole numbers a and b such that a ∨ b = 23 is not possible. To see this, we can consider the fact that both a^2 and b^2 are non-negative values.
Since a ∨ b is the sum of two non-negative values, the minimum value it can have is 0 when both a and b are 0. Therefore, it is not possible for a ∨ b to equal 23 using whole numbers.

To avoid this, the country removed the restriction on the second digit. How many area codes are available under the new system?
A) There are 28 possible area codes. The country permits 7,000,000 telephone numbers per area code. b) There are 140 area codes available under the new system.
a) There are two possible choices for the first digit (since 0 and 1 are not allowed), two possible choices for the second digit (since 0 or 1 can be used) and seven choices for the third digit (since 2 is not allowed).
Therefore, the total number of possible area codes is:2 × 2 × 7 = 28
The total number of telephone numbers per area code can be calculated by using the product principle again, considering that 0, 1, and 2 are not allowed as the first digit and there are 10 choices for each of the other six digits: 7 × 10 × 10 × 10 × 10 × 10 × 10 = 7 × 106 = 7,000,000.
Therefore, the country allows 7,000,000 telephone numbers per area code.

7) If f(x)=7x3, what is df/dx?
8) If f(x) = 1000+ 3x, what is df/dx?
The derivative of f(x) = 10x is df/dx = 10. the derivative of f(x) = (1000 - 2x)x is df/dx = 1000 - 4x.the derivative of f(x) = 7x^3 is df/dx = 21x^2.the derivative of f(x) = 1000 + 3x is df/dx = 3.
If f(x) = 10x, the derivative df/dx can be found by differentiating f(x) with respect to x.
df/dx = d/dx (10x)
Using the power rule for differentiation, where d/dx (x^n) = nx^(n-1):
df/dx = 10
Therefore, the derivative of f(x) = 10x is df/dx = 10.
6) If f(x) = (1000 - 2x)x, we need to expand the terms before differentiating.
f(x) = (1000 - 2x)x
Expanding the expression:
f(x) = 1000x - 2x^2
To find df/dx, we differentiate f(x) with respect to x:
df/dx = d/dx (1000x - 2x^2)
Using the power rule and the constant multiple rule for differentiation:
df/dx = 1000 * d/dx (x) - 2 * d/dx (x^2)
df/dx = 1000 * 1 - 2 * 2x^(2-1)
df/dx = 1000 - 4x
Therefore, the derivative of f(x) = (1000 - 2x)x is df/dx = 1000 - 4x.
7) If f(x) = 7x^3, we can find df/dx by differentiating f(x) with respect to x.
df/dx = d/dx (7x^3)
Using the power rule for differentiation:
df/dx = 7 * d/dx (x^3)
df/dx = 7 * 3x^(3-1)
df/dx = 21x^2
Therefore, the derivative of f(x) = 7x^3 is df/dx = 21x^2.
8) If f(x) = 1000 + 3x, we can find df/dx by differentiating f(x) with respect to x.
df/dx = d/dx (1000 + 3x)
Since 1000 is a constant, its derivative is zero. The derivative of 3x is 3.
df/dx = 0 + 3
df/dx = 3

Prove that for each positive integer n, we have that 3∣(2 n(n−1) −1).
To prove that for each positive integer n, 3 divides (2n(n-1) - 1), we can use mathematical induction. Base Case:
For n = 1, we have:
2(1)(1-1) - 1 = 2(0) - 1 = -1
Since -1 is divisible by 3 (as -1 = -3 * 0 + (-1)), the statement holds true for the base case. Inductive Step:
Assume that for some positive integer k, 3 divides (2k(k-1) - 1). We will prove that this implies the statement is true for k+1 as well.
We need to show that 3 divides (2(k+1)(k+1-1) - 1).
Expanding this expression:
2(k+1)(k) - 1 = 2k(k+1) - 1 = 2k^2 + 2k - 1
We can rewrite 2k^2 + 2k - 1 as 2k^2 + k + k - 1.
Now, we can consider the term (2k^2 + k) separately. Assume that 3 divides this term, i.e., 2k^2 + k is divisible by 3.
We can write 2k^2 + k as 3p, where p is some integer.
Therefore, assuming that 3 divides (2k(k-1) - 1) holds for k, we have shown that it holds for k+1 as well.
By the principle of mathematical induction, we can conclude that for each positive integer n, 3 divides (2n(n-1) - 1).

You should add 7.2 fluid ounces of oil to the 3 quarts of gas. To determine the amount of oil needed, we'll convert the given 3 quarts of gas into gallons, and then use the specified oil-to-gas ratio of 2.4 fluid ounces of oil per gallon of gas.
1 quart = 0.25 gallons (since 1 gallon = 4 quarts)
3 quarts = 3 * 0.25 = 0.75 gallons
Now, we can calculate the amount of oil needed:
Amount of oil = (0.75 gallons) * (2.4 fl. oz./gallon)
Calculating:
Amount of oil = 1.8 fluid ounces
Therefore, you should add 1.8 fluid ounces of oil to the 3 quarts of gas.
To mix the oil and gas in the specified ratio of 2.4 fluid ounces of oil per gallon of gasoline, you should add 1.8 fluid ounces of oil to the 3 quarts of gas. It's important to follow the correct ratio to ensure proper lubrication and functioning of your Puch Maxi Moped. Enjoy your ride!

The simplified Big O notation can be defined as a standard way of expressing the time complexity of an algorithm. The big-O notation uses a function to describe the growth rate of the algorithm as the input size increases.
Big O notation is commonly used to describe the upper bound of time complexity and space complexity. The simplified Big O notation can be defined as the complexity of the algorithm in terms of how many operations it needs in the worst-case scenario.
It is a standard way of expressing the time complexity of an algorithm. The big-O notation uses a function to describe the growth rate of the algorithm as the input size increases. Let's solve the given expression O( c4N4+c81N2)+O(N4) using simplified Big O notation; O( c4N4+c81N2) + O(N4) is equivalent to O( c4N4+c81N2+N4)
Using the rule of thumb that, in Big O notation, we only keep the highest-order term and ignore any constants, we can simplify this further.
Therefore, O( c4N4+c81N2+N4) simplifies to O(N4) because N4 is the highest-order term. Therefore, the Big O notation for the given expression is O(N4).
In the given expression O( c4N4+c81N2)+O(N4), the simplified Big O notation is O(N4).
