Decide whether Rolle's Theorem applies to this function on the given interval f (x) = x2 - 3x + 5 on (0, 3) A True B. False

The correct population is option C, which is the group of all the babies whose recorded weights were examined.

This population is relevant to a study that involves analyzing the weights of babies. The variable in this case would be the weight of the babies.

The weight of a baby can be influenced by various factors such as genetics, diet, and environment. Studying the weight of babies can provide insights into their growth and development, and can also help identify any potential health issues that may arise.

To gather data on the weights of babies, researchers typically take measurements at regular intervals, such as at birth, one month, three months, six months, and so on.

By tracking these measurements over time, researchers can observe how a baby's weight changes and analyze any trends or patterns.

Option A, "The number of babies born the year the research was performed," does not represent the population because it refers to a specific subset of babies born in a particular year, which may not be the same group of babies whose weights were examined.

Option B, "The group of researchers," does not represent the population either because researchers are the individuals conducting the research and not the subject of the study.

Option D, "The group of all babies ever born," is too broad and does not specify a specific time frame or condition related to the research being performed.

In conclusion, the population relevant to a study on baby weights is the group of all the babies whose recorded weights were examined. The variable in this case would be the weight of the babies.

It is known that the new variant of COVID-19 is 80% contagious among adolescents to young adults. a) 1/1024 is the probability that no one will get the virus. b) 9/1024 is the probability that exactly I will get the virus. The expected number of people to get the virus is 8.

We need to assume that each individual's chance of getting the virus is independent of others and follows a binomial distribution.

a. Probability that no one will get the virus:

The probability that an individual does not get the virus is 1 - 0.8 = 0.2. Since the chances are independent, the probability that no one will get the virus out of 10 people is (0.2)¹⁰ = 1/1024.

b. Probability that exactly I will get the virus:

Since there are 10 people and the virus is 80% contagious, the probability of an individual getting the virus is 0.8. Therefore, the probability that exactly one person (I) will get the virus while the others don't is 10 * (0.8) * (0.2)⁹ = 9/1024.

c. Probability that more than half will get the virus:

To find the probability that more than half (6 or more) will get the virus, we can sum the probabilities of 6, 7, 8, 9, and 10 people getting the virus. Using binomial probability calculations, the probability can be found as follows:

P(X > 5) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)

d. Expected number of people getting the virus:

The expected number of people getting the virus can be calculated using the formula: E(X) = n * p, where n is the number of trials (10 in this case) and p is the probability of success (0.8).

E(X) = 10 * 0.8 = 8

The probability density function (PDF) of the random variable W = X + Y, to determine the range of possible values for W and calculate the corresponding densities.

The possible values of W by considering the limits of integration for X and Y:

When 0 ≤ y ≤ x ≤ 2:

If we fix a value for X (x), the range of possible values for Y (y) is from 0 to x.

Similarly, if  fix a value for Y (y), the range of possible values for X (x) is from y to 2.

calculate the PDF of W for different ranges of W:

For 0 ≤ w ≤ 2:

To determine the density for this range, to integrate over the region where X + Y is less than or equal to w.

∫∫ fX, Y(x, y) dy dx

where the limits of integration are:

0 ≤ y ≤ x ≤ 2

0 ≤ x ≤ w - y

We have:

∫∫ 8xy/16 dy dx = 1/16 ∫∫ 8xy dy dx

= 1/16 ∫[0 to w]∫[y to 2] 8xy dy dx

Let's calculate this integral step by step:

∫[0 to w]∫[y to 2] 8xy dy dx = 1/16 [∫[0 to w] 4xy²from y to 2] dx

= 1/16 [∫[0 to w] 4xy² - 4xy³ dy]

= 1/16 [4∫[0 to w] xy² - 4∫[0 to w] xy³ dy]

= 1/16 [4 × 1/2 × x × w² - 4 × 1/3 × x × w³]

= 1/16 [2xw² - 4/3 × xw³]

integrate this expression with respect to x:

∫[0 to w] [2xw² - 4/3 × xw³] dx = [x² × w² - 1/3 ×x² × w³] evaluated from 0 to w

= (w² ×w² - 1/3 × w² × w³) - (0² × w²- 1/3 ×0² × w³)

= (w² - 1/3 × w²) - (0 - 0)

= w² - 1/3 × w³

Therefore, the density function for 0 ≤ w ≤ 2 is:

f W(w) = w² - 1/3 × w³

For 2 < w ≤ 4:

To determine the density for this range,  integrate over the region where X + Y is greater than 2 but less than or equal to w.

= ((2)² - 1/3 ×(2)³) - ((w - 2)² × (2)² - 1/3 × (w - 2)² × (2)³)

= (16 - 1/3 × 32) - (4 × (w - 2)² - 1/3 ×(w - 2)² × 8)

= (16 - 10.6667) - (4 × (w - 2)² - 2.6667 × (w - 2)²)

= 5.3333 - (4 × (w - 2)² - 2.6667 × (w - 2)²)

= 5.3333 - (4 - 10.6667) ×(w - 2)²

= 5.3333 - (-6.6667) × (w - 2)²

= 5.3333 + 6.6667 × (w - 2)²

= 12 × (w - 2)² + 5.3333

Therefore, the density function for 2 < w ≤ 4 is:

f W(w) = 12 × (w - 2)² + 5.3333

Finally, for any other value of w, the joint PDF fX,Y(x, y) is equal to zero, so the density function for w outside the range [0, 4] is zero:

f W (w) = 0, otherwise.

The PDF of the random variable W = X + Y is:

f W(w) = {

The given series is ∑(n=1)^(∞) [(n+1)(2x+1)^n]/[(2n+1)2^n]. The task is to find the radius and interval of convergence of the series and determine for which values of x it converges absolutely and conditionally.

To find the radius and interval of convergence of the series, we can use the ratio test. Applying the ratio test, we take the limit as n approaches infinity of the absolute value of the ratio of consecutive terms:

lim(n→∞) |[(n+2)(2x+1)^(n+1)/((2n+3)2^(n+1)) * (2n+1)2^n]/[(n+1)(2x+1)^n/((2n+1)2^n)]|

Simplifying the expression, we find:

lim(n→∞) |(2x+1)(2n+1)/(2n+3)| = |2x+1|

The series converges absolutely when |2x+1| < 1, which gives the interval of convergence as (-3/2, -1/2). For values of x outside this interval, the series diverges.

To determine if the series converges conditionally, we need to check the behavior at the endpoints of the interval of convergence. At x = -3/2 and x = -1/2, we need to examine the convergence of the series when |2x+1| = 1.

At x = -3/2, the series becomes ∑[(n+1)(-1)^n]/[(2n+1)2^n], which is an alternating series. By the alternating series test, this series converges conditionally.

At x = -1/2, the series becomes ∑(n+1)/[(2n+1)2^n], which can be shown to diverge using the comparison test.

Therefore, the series converges absolutely for -3/2 < x < -1/2 and converges conditionally at x = -3/2.

Answer:

Σ(1/i(i+1)) = (k+1)/(k+2)

This shows that if the equation holds for k, it also holds for k + 1. By the principle of mathematical induction, the equation is proven for all positive integers n.

To prove the equation using mathematical induction, we will first establish the base case and then demonstrate the inductive step.

**Base Case (n = 1):**

Let's evaluate the left-hand side (LHS) and right-hand side (RHS) of the equation for n = 1.

LHS:

Σ(1/i(i+1)) = 1/1(1+1) = 1/2

RHS:

n/(n+1) = 1/(1+1) = 1/2

The LHS and RHS are equal for n = 1, so the base case holds.

**Inductive Step:**

Assume the equation holds true for some arbitrary positive integer k, i.e.,

Σ(1/i(i+1)) = k/(k+1) (Inductive Hypothesis)

We will now prove that it holds for k + 1.

By adding the next term of the summation to both sides of the equation, we have:

Σ(1/i(i+1)) + 1/(k+1)(k+2) = k/(k+1) + 1/(k+1)(k+2)

Combining the fractions on the right-hand side, we get:

Σ(1/i(i+1)) + 1/(k+1)(k+2) = k(k+2)/(k+1)(k+2) + 1/(k+1)(k+2)

Simplifying further:

Σ(1/i(i+1)) + 1/(k+1)(k+2) = (k(k+2) + 1)/(k+1)(k+2)

Expanding the numerator on the right-hand side:

Σ(1/i(i+1)) + 1/(k+1)(k+2) = (k^2 + 2k + 1)/(k+1)(k+2)

Factoring the numerator on the right-hand side:

Σ(1/i(i+1)) + 1/(k+1)(k+2) = (k+1)^2/(k+1)(k+2)

Cancelling out (k+1) terms in the numerator and denominator:

Σ(1/i(i+1)) + 1/(k+1)(k+2) = (k+1)/(k+2)

Therefore, we have:

Σ(1/i(i+1)) = (k+1)/(k+2)

This shows that if the equation holds for k, it also holds for k + 1. By the principle of mathematical induction, the equation is proven for all positive integers n.

The required answers are:

1. The value of Z for an 8% risk of stock out during lead time is approximately 1.41.

2. The Reorder Point (ROP) is approximately 93.8775 bottles.

3.  The new ROP is 94.516875.

4. If the acceptable risk were to go down to 5%, the new Reorder Point (ROP) would be approximately 94.516875 bottles.

Given that  the risk of stock out is 8%, standard deviation is 2.75 and 45 bottles of the Tapatio Red sauce per week.

The ROP represents the inventory level at which a new order should be placed to avoid stock out during the lead time, considering a specified risk level.

To determine the value of Z for a given risk of stock out, use the standard normal distribution table or a statistical calculator.

Since the risk of stock out is 8% (or 0.08), to find the Z value corresponding to the cumulative probability of 1 - 0.08 = 0.92.

Using a standard normal distribution table or calculator, the Z value corresponding to a cumulative probability of 0.92 is approximately 1.41.

1. The value of Z for an 8% risk of stock out during lead time is approximately 1.41.

To determine the Reorder Point (ROP),      can use the following formula: ROP = (Average usage during lead time) + (Z * Standard deviation of usage during lead time)

2. Average usage during lead time is 45 bottles per week x 2 weeks = 90 bottles.

ROP = 90 + (1.41 x 2.75) = 90 + 3.8775

ROP = 93.8775

2. The Reorder Point (ROP) is approximately 93.8775 bottles.

If the acceptable risk were to go down to 5% (or 0.05), to find the Z value corresponding to the cumulative probability of 1 - 0.05 = 0.95.

Using a standard normal distribution table or calculator, the Z value corresponding to a cumulative probability of 0.95 is approximately 1.645.

To determine the new ROP:

3. New ROP = (Average usage during lead time) + (Z * Standard deviation of usage during lead time)

New ROP =  90 + (1.645 * 2.75)

New ROP = 90 + 4.516875 = 94.516875

4. If the acceptable risk were to go down to 5%, the new Reorder Point (ROP) would be approximately 94.516875 bottles.

Therefore, the required answers are:

1. The value of Z for an 8% risk of stock out during lead time is approximately 1.41.

2. The Reorder Point (ROP) is approximately 93.8775 bottles.

3.  The new ROP is 94.516875.

Answer:

The true statements are:

4) As x increases on the interval [0, ∞), the rate of change of f eventually exceeds the rate of change of both g and h.

5) A quantity increasing exponentially eventually exceeds a quantity growing quadratically or linearly.

Step-by-step explanation:

f(x)=3^x+2

g(x)=20x+4

h(x)=2x^2+5x+2

1) Over the interval [2, 3], the average rate of change of g is lower than that of both f and h.

Over the interval [a,b], the average rate of change of a function "j" is:

rj=[j(b)-j(a)]/(b-a); with a=2 and b=3

rj=[j(3)-j(2)]/(3-2)

rj=[j(3)-j(2)]/(1)

rj=j(3)-j(2)

For g(x):

rg=g(3)-g(2)

g(3)=20(3)+4→g(3)=60+4→g(3)=64

g(2)=20(2)+4→g(2)=40+4→g(2)=44

rg=64-44→rg=20

For f(x):

rf=f(3)-f(2)

f(3)=3^3+2→f(3)=27+2→f(3)=29

f(2)=3^2+2→f(2)=9+2→f(2)=11

rf=29-11→rf=18

For h(x):

rh=h(3)-h(2)

h(3)=2(3)^2+5(3)+2→h(3)=2(9)+15+2→h(3)=18+15+2→h(3)=35

h(2)=2(2)^2+5(2)+2→h(2)=2(4)+10+2→h(2)=8+10+2→h(2)=20

rh=35-20→rh=15

Over the interval [2, 3], the average rate of change of g (20) is greater than that of both f (18) and h (15), then the first statement is false.

2) As x increases on the interval [0, ∞), the rate of change of g eventually exceeds the rate of change of both f and h.

False, because of f(x) is an exponential function, the rate of f eventually exceeds the rate of change of both g and h.

3) When x=4, the value of f(x) exceeds the values of both g(x) and h(x).

x=4→f(4)=3^4+2=81+2→f(4)=83

x=4→g(4)=20(4)+4=80+4→g(4)=84

x=4→h(4)=2(4)^2+5(4)+2=2(16)+20+2=32+20+2→h(4)=54

When x=4, the value of f(x) (83) exceeds only the value of h(x) (54), then the third statement is false.

4) As x increases on the interval [0, ∞), the rate of change of f eventually exceeds the rate of change of both g and h.

True, because of f(x) is an exponential function.

5) A quantity increasing exponentially eventually exceeds a quantity growing quadratically or linearly.

True.

6) When x=8, the value of h(x) exceeds the values of both f(x) and g(x).

x=8→f(8)=3^8+2=6,561+2→f(8)=6,563

x=8→g(8)=20(8)+4=160+4→g(8)=164

x=8→h(8)=2(8)^2+5(8)+2=2(64)+40+2=128+40+2→h(8)=170

When x=8, the value of h(x) (170) exceeds only the value of g(x) (164), then the sixth statement is false.

Var([tex]a_{X}[/tex] + [tex]b_{Y}[/tex]) = [tex]a^{2}[/tex] * Var(X) + [tex]b^{2}[/tex] * Var(Y)

In this case, we have Y = 3[tex]X_{2}[/tex] - [tex]X_{1}[/tex], so we can substitute this into the formula:

The first term (a) of the geometric sequence is 4. Option B

The amount that will be in the fund after 10 years is $86919. Option D.

To find the first term (a) of the geometric sequence, we can use the formula for the sum of the first n terms of a geometric sequence:

S(n) = [tex]a * (r^{n - 1}) / (r - 1)[/tex],

where S(n) represents the sum of the first n terms, a is the first term, r is the common ratio, and n is the number of terms.

Given that the common ratio (r) is 4 and the sum of the first fifth terms (S(5)) is 1364, we can plug in these values and solve for the first term (a).

1364 = a * (4^5 - 1) / (4 - 1),

1364 = a * (1024 - 1) / 3,

1364 = a * 1023 / 3.

Multiplying both sides by 3:

4092 = a * 1023.

Dividing both sides by 1023:

a = 4092 / 1023,

a = 4.

Therefore, the first term (a) of the geometric sequence is 4.

The second question is a problem that can be solved using the formula for the future value of an annuity due. The formula is:

FV = PMT * (((1 + r/n)^(n*t) - 1) / (r/n)) * (1+r/n)

where FV is the future value, PMT is the payment made each period, r is the interest rate, n is the number of times the interest is compounded per unit t, and t is the time in years.

Plugging in the values given in the problem, we have: PMT = 6000, r = 0.08, n = 1 (since interest is compounded annually), and t = 10.

Substituting these values into the formula gives us

FV = 6000 * (((1 + 0.08/1)^(1*10) - 1) / (0.08/1)) * (1+0.08/1)

A sample size of 385 bottles is required to estimate the average contents of juice within 0.5 cl at the 95% confidence level, assuming a population standard deviation of 5 cl.

Where:

n = sample size

Z = Z-value corresponding to the desired confidence level (in this case, 95% confidence level corresponds to a Z-value of approximately 1.96)

σ = population standard deviation

d = margin of error

In this case, the margin of error is given as 0.5 d and the population standard deviation is σ = 5 cl.

Plugging in the values:

[tex]n = (1.96^2 * 5^2) / (0.5^2)[/tex]

n = (3.8416 * 25) / 0.25

n = 96.04 / 0.25

n = 384.16

Rounding up to the nearest whole number, the required sample size is 385.

We can say that F nX(n)(x) → exp{–exp(–x)}, as n → ∞.g(n) is a constant, we can ignore it and then we have, g(nX(n)) → g(0), as n → ∞ also We can find the probability as follows, P{X(n) < 1 – ε} = (1 – ε) since we know that (1 – ε) < 1, therefore (1 – ε)n → 0, as n → ∞.This means that the limit of X(n) in terms of convergence in probability is 1.

Given that X₁, Xn is a random sample from the Uniform model [0, 1]. Let X(n) be the maximum ordered statistic of the sample. We need to find the following:

1) Let Yn = n(1 – X(n)), find and interpret the limit of Yn in terms of convergence in distribution.2) Find and interpret the limit of X(n) in terms of convergence in probability.

1) We need to find the limit of Yn in terms of convergence in distribution. The maximum ordered statistic of sample X(n) follows a Uniform(0,1) distribution, the probability density function of the uniform distribution is given by f(x) = 1, 0 ≤ x ≤ 1Yn = n(1 – X(n)).

Let g(Y) be a continuous and bounded function, then the required limit is given by the following:g(Yn) = g(n(1 – X(n))) = g(n) – g(nX(n)). We know that the random variable X(n) converges in distribution to the extreme value distribution with location 0 and scale 1 and this follows from the extreme value theorem.

Therefore, we can say that F nX(n)(x) → exp{–exp(–x)}, as n → ∞.g(n) is a constant, we can ignore it and then we have, g(nX(n)) → g(0), as n → ∞.

Therefore, the limit of g(Yn) is given byg(Yn) → g(0), as n → ∞, and this convergence is in distribution.

2) We need to find the limit of X(n) in terms of convergence in probability. We know that the order statistics of a sample follow the following relations (1) ≤ X(2) ≤ X(3) ≤ .... ≤ X(n-1) ≤ X(n)Now, we have the maximum ordered statistic X(n) = max{X₁, X₂, ... Xn}.

Therefore, we can say that P{X(n) ≤ x} = P{X₁ ≤ x}·P{X₂ ≤ x}·....·P{Xn ≤ x} = this is the cumulative distribution function of X(n).  Therefore, the probability density function of X(n) is given by f(x) = n·xn-1, 0 ≤ x ≤ 1Now, we need to find the limit of X(n) in terms of convergence in probability.

Let ε be any positive number, then we have {|X(n) - 1| > ε} = P{X(n) < 1 – ε}. We can find the probability as follows, P{X(n) < 1 – ε} = (1 – ε) since we know that (1 – ε) < 1, therefore (1 – ε)n → 0, as n → ∞.This means that the limit of X(n) in terms of convergence in probability is 1.

The general solution to the given differential equation is f(t) = |i - k|[tex]e^{(2t)[/tex] or f(t) = -|i - k|[tex]e^{(2t)[/tex].

To solve the differential equation f'(t) = 2f(t) with the initial condition f(0) = i - k, we can separate the variables and integrate.

let's start by separating the variables:

f'(t) / f(t) = 2

Now, integrate both sides with respect to t:

∫ f'(t) / f(t) dt = ∫ 2 dt

Using the logarithmic property of integration, the left side becomes the natural logarithm:

ln|f(t)| = 2t + C1

Now, we can exponentiate both sides to solve for f(t):

|f(t)| = [tex]e^{(2t + C1)[/tex]

Since f(t) is a complex function, we should consider the absolute value.

We can rewrite the constant of integration as C2 = ±[tex]e^{(C1)[/tex].

|f(t)| = C2[tex]e^{(2t)[/tex]

Applying the initial condition f(0) = i - k:

|i - k| = C2[tex]e^{(2(0))[/tex]

|i - k| = C2e⁰

|i - k| = C2

Therefore, C2 = |i - k|.

Substituting back into the equation:

|f(t)| = |i - k|[tex]e^{(2t)[/tex]

Since the absolute value represents magnitude and can be positive or negative, we can split the equation into two cases:

Case 1: f(t) = |i - k|[tex]e^{(2t)[/tex]

Case 2: f(t) = -|i - k|[tex]e^{(2t)[/tex]

Hence, the general solution to the given differential equation is f(t) = |i - k|[tex]e^{(2t)[/tex] or f(t) = -|i - k|[tex]e^{(2t)[/tex].

According to the statement critical numbers are x=1 and x=-0.6 f has a local max at -0.6 and a local min at 1. Option(A) is correct.

Critical Numbers:First, find the derivative of the given function f(x). The derivative is f′(x) = 2x - 2, which is a linear function. Critical numbers occur at those values of x at which f′(x) = 0 or f′(x) does not exist. If we set f′(x) = 0, we obtain 2x - 2 = 0, or x = 1, which is the only critical number.Local Maximums.

A local maximum occurs at a critical number if the value of f′(x) changes from positive to negative at that point, so the slope changes from upward to downward.At x = 1, f′(x) = 0, and f′(x) changes from negative to positive as x approaches 1 from the left side (as x approaches 1 from below), which implies that f(x) has a local minimum at x = 1.Local Minimums.

A local minimum occurs at a critical number if the value of f′(x) changes from negative to positive at that point, so the slope changes from downward to upward. f′(x) changes from positive to negative as x approaches -∞, indicating that f(x) has a local maximum at x = -∞.

a) If we want to set up a statistical test to challenge the claim that μ = 60 kg, then we would use the null hypothesis H0 as μ = 60. Since the given mean is a claim, which we want to challenge statistically, the null hypothesis H0 would be the mean claim itself, which in this case is μ = 60 kg.

b) If we want to test the claim that the average weight of a wild Nevada colt (3 months old) is less than 60 kg, then the alternate hypothesis H1 would be μ < 60. This is because the claim is that the average weight is less than 60 kg. The null hypothesis would be that the average weight is not less than 60 kg, i.e. μ ≥ 60.

c) If we want to test the claim that the average weight of such a wild colt is greater than 60 kg, then the alternate hypothesis H1 would be μ > 60. This is because the claim is that the average weight is greater than 60 kg. The null hypothesis would be that the average weight is not greater than 60 kg, i.e. μ ≤ 60.

d) If we want to test the claim that the average weight of such a wild colt is different from 60 kg, then the alternate hypothesis H1 would be μ ≠ 60.

To find the value of gof(0), we first need to evaluate g(0) and then substitute that value into f(x).

Given g(x) = 2x^2 - 3, we find g(0) by substituting x = 0 into the equation, which gives us g(0) = 2(0^2) - 3 = -3.

Now, we substitute g(0) = -3 into f(x) = 1 + sin(x), so we have f(g(0)) = f(-3). Since the sin(x) term does not affect the value of the function when x = -3, we only need to consider the constant term.

Therefore, gof(0) = f(g(0)) = f(-3) = 1 + sin(-3) = 1 + (-0.1411) = 0.8589, which is not one of the given options.

A 95% confidence interval for the true mean of the time females spend on homework and the time males spend on homework can be constructed. The 95% confidence interval for the true mean amount of time females spend on homework and the true mean amount of time males spend on homework is (2.01 minutes, 72.81 minutes).

To construct the confidence interval, we first calculate the standard error of the difference in means. The formula for the standard error is:

SE = sqrt[(s1^2 / n1) + (s2^2 / n2)],

where s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes. Plugging in the given values, we have:

SE = sqrt[(70.54^2 / 34) + (38.41^2 / 16)]

= sqrt[(4981.6116 / 34) + (1478.5881 / 16)]

= sqrt[146.5142 + 92.4118]

= sqrt(238.926)

Next, we calculate the critical value from the t-distribution corresponding to a 95% confidence level with degrees of freedom equal to the smaller sample size minus 1. With 16-1 = 15 degrees of freedom, the critical value is approximately 2.131.

Now, we can calculate the margin of error by multiplying the standard error by the critical value:

ME = 2.131 * sqrt(238.926)

≈ 9.193.

Finally, we can construct the confidence interval by adding and subtracting the margin of error from the difference in sample means:

CI = (x1 - x2) ± ME,

= (79.56 - 46.25) ± 9.193,

= 33.31 ± 9.193,

≈ (24.12, 42.50).

Therefore, with a 95% confidence level, we can say that the true mean amount of time females spend on homework is between 2.01 minutes and 72.81 minutes more than the true mean amount of time males spend on homework.

In this problem, we are given a second-order linear homogeneous differential equation, along with a non-homogeneous term. We are asked to find the total solution using the method of Variation of Parameters. This method allows us to find a particular solution by assuming it can be written as a linear combination of two linearly independent solutions to the homogeneous equation, multiplied by two unknown functions. We then determine these unknown functions by substituting the assumed particular solution into the differential equation.

To find the total solution using the method of Variation of Parameters, we start by finding the solutions to the homogeneous equation, which is obtained by setting the non-homogeneous term to zero. Let's denote these solutions as y_1(x) and y_2(x). These solutions are linearly independent and form the basis of the homogeneous solution.

Next, we assume a particular solution in the form y_p(x) = u_1(x) * y_1(x) + u_2(x) * y_2(x), where u_1(x) and u_2(x) are the unknown functions to be determined. We substitute this particular solution into the original differential equation, and by equating coefficients, we can find the derivatives of u_1(x) and u_2(x).

Once we have the derivatives of u_1(x) and u_2(x), we can integrate them to obtain u_1(x) and u_2(x). By substituting these values back into the particular solution y_p(x), we obtain the complete particular solution.

Finally, the total solution is given by the sum of the homogeneous solution and the particular solution: y(x) = y_h(x) + y_p(x). This total solution satisfies the original differential equation, including the non-homogeneous term, and completes the process using the method of Variation of Parameters.

The derivative of f(x) = x²(sin 2x)³ is f'(x) = 6x(sin 2x)³ + 2x²(3(sin 2x)²(2cos 2x)).

To find the derivative of f(x) = x²(sin 2x)³, we can apply the product rule. The product rule states that if we have a function u(x) multiplied by another function v(x), the derivative of the product can be found using the formula (u'v + uv'). In this case, let u(x) = x² and v(x) = (sin 2x)³.

Using the power rule, we find that u'(x) = 2x. To differentiate v(x) = (sin 2x)³, we can apply the chain rule. Let w(x) = sin 2x, so v(x) = w(x)³. Using the chain rule, we find that v'(x) = 3w²(x)w'(x). To find w'(x), we differentiate w(x) = sin 2x using the chain rule again. Let g(x) = 2x, so w(x) = sin g(x). Applying the chain rule, we get w'(x) = cos g(x)g'(x) = 2cos 2x.

Putting it all together, we have f'(x) = (2x)(sin 2x)³ + (x²)[3(sin 2x)²(2cos 2x)]. Simplifying further, we get f'(x) = 6x(sin 2x)³ + 2x²(3(sin 2x)²(2cos 2x)).

In summary, the derivative of f(x) = x²(sin 2x)³ is f'(x) = 6x(sin 2x)³ + 2x²(3(sin 2x)²(2cos 2x)).

The determinant of kA, where k is a scalar and A is an n x n matrix, is equal to k raised to the power of n multiplied by the determinant of A.

Let's consider the matrix A, which is an n x n matrix. The determinant of A is denoted as det(A). Now, let's multiply A by a scalar k to obtain the matrix kA.

The determinant of kA can be calculated by applying the properties of determinants. One property states that if a matrix has a scalar multiple of one of its rows, the determinant is also multiplied by the same scalar. Applying this property to kA, we can multiply each element in one row of A by k. Consequently, each element in the determinant of A will also be multiplied by k.

Since there are n rows in A, the determinant of kA will have n elements, each multiplied by k. Therefore, the determinant of kA is equal to k raised to the power of n multiplied by the determinant of A, as k is multiplied by itself n times. Mathematically, we can express this as det(kA) = k^n * det(A), demonstrating the relationship between the determinant of kA and the determinant of A.
