The solution is a simple process of subtracting the largest coin value from the total amount, adding any coins that fit, and repeating the process until the total amount is reached. This algorithm guarantees that the minimum number of coins needed to arrive at the total will be displayed.

1. Start by subtracting the largest coin value from the total amount.

2. If the difference is greater than 0, add the coin to the total and repeat the process.

3. If the difference is 0, move onto the next smallest coin value.

4. Repeat the process until the total amount is reached.

5. Once the total amount is reached, the minimum amount of coins needed to arrive at the total will be displayed.

Answer:

a. To find the factor by which the area decreases in 10 years, we can use the formula for exponential decay: A(t) = A0 * e^(-kt) where A0 is the initial area, k is the decay constant, and t is the time in years.

Given that A(t) = 11 -0.98^t.

so, we can say k =0.98

The area after 10 years will be:

A(10) = 11 - 0.98^10

The decrease factor is:

(A(10)/A(0)) = (11 - 0.98^10)/11

b. To find the factor by which the area decreases each month, we can first convert the annual decay rate to a monthly rate by dividing by 12, since there are 12 months in a year.

So, the monthly decay rate is 0.98/12 = 0.0816

Then we can use the formula for exponential decay again with the new decay rate:

A(t) = A0 * e^(-kt)

The area after 1 month will be:

A(1/12) = 11 - 0.0816^(1/12)

The decrease factor is :

(A(1/12)/A(0)) = (11 - 0.0816^(1/12))/11

The sum of the eigenvalues of matrix A is 8 and the product of eigenvalues is -15.

What is the eigenvalue?

Eigenvalues are the special set of scalar values that are associated with the set of linear equations most probably in the matrix equations. The eigenvectors are also termed characteristic roots.

To find the eigenvalues of matrix A, we can solve the characteristic equation |A - λI| = 0, where λ is a scalar and I is the identity matrix.

|A - λI| = 3- λ 1 4 0 2- λ 6 0 0 5- λ

= (3-λ)(5-λ) - 24 = λ^2 - 8λ - 15

Setting λ^2 - 8λ - 15 = 0, we can find the eigenvalues of the matrix by solving the quadratic equation.

λ^2 - 8λ - 15 = 0

λ = (8 ± √(8^2 + 4*15))/2

λ = (8 ± √(64 + 60))/2

λ = (8 ± √124)/2

So the eigenvalues of matrix A are λ_1 = (8 + √124)/2 and λ_2 = (8 - √124)/2

The sum of eigenvalues is λ_1 + λ_2 = (8 + √124)/2 + (8 - √124)/2 = 8

The product of eigenvalues is λ_1 * λ_2 = (8 + √124)/2 * (8 - √124)/2 = -15

Hence, the sum of the eigenvalues of matrix A is 8 and the product of eigenvalues is -15.

The length of the remaining candle is equal to the total length of the candle minus the length of the candle that has been burned, or (total length - b).

The length of the remaining candle can be calculated by subtracting the length of the candle that has been burned (b) from the total length of the candle. This is because when a candle is burned, the length of the candle decreases. To calculate the remaining length of the candle, start by determining the total length of the candle. Then, subtract the length of the candle that has been burned (b). The result is the length of the remaining candle. The formula for this calculation is (total length - b).  The length of the candle remaining is (b - 2). For example, if the total length of the candle is 6 inches and 2 inches of the candle have been burned, the remaining length of the candle would be 4 inches (6 - 2 = 4).

This is of the form [tex]$\frac{d y}{d x}[/tex] + P(x)y = Q(x) which is the linear equation.

In order to solve this kind of differential equation, we have to multiply it by an integrating factor.

Here, P = - ln (x), Q(x) = 3 [tex]x^x[/tex]

I F = [tex]e^{\int P d x}[/tex]

I F = [tex]e^{-\int \ln (x)}[/tex]

I F = [tex]e^{-(x \ln x-x)}[/tex]

I F = [tex]e^{x-x \ln x}[/tex]

x = -5

f(-5) = (-5)² + -5 - 12 = 25 - 5 - 12 = 8

g(f(-5)) = -31

We solve this system of equations and we can note that the system don't have a solution, so the vector b is not a linear combination of a1, a2, and a3.

First of all we put the vectors in terms of different variables, such as:

a1(1,-2,0)=(a,-2a,0);

a2(0,1,3)=(0,b,3b);

a3(6,-6,18)=(6c,-6c,18c);

To know that a vector is a linear combination we need to express it like a sum of other different vectors.

(2,-2,6)=(a,-2a,0)+(0,b,3b)+(6c,-6c,18c)

(2,-2,6)=(a+0+6c,-2a+b-6c,0+3b+18c)

We express this sum like a system of equations.

a+6c=2

-2a+b-6c=-2

Considering the definition of probability, the probability that the selected student is in none of the clubs listed is 0.375 or 37.5%.

Probability is the greater or lesser chance that a given event will occur.

In other words, the probability establishes a relationship between the number of favorable events (number of cases in which event A may or may not occur)  and the total number of possible events through the Laplace's Law as follow:

P(A)= number of favorable cases÷number of total cases

In this case, you know:

Replacing in the definition of probability:

There is 99% confidence that the population mean number of books read is between 1.51 and 26.69. This confidence interval indicates that there is a 99% probability that the true mean number of books read by people in the past year falls between 1.51 and 26.69.

Confidence interval for the mean = (x - z(s/√n), x + z(s/√n))

Where x is the sample mean, s is the sample standard deviation, n is the sample size, and z is the critical value for the given confidence level (in this case, 99%).

Therefore, the confidence interval for the mean number of books read is:

(14.1 - 2.58(16.6/√1018), 14.1 + 2.58(16.6/√1018))

The angular momentum of the flywheel is equal to the product of the applied torque, the time interval, and the moment of inertia. Therefore, the angular momentum of the flywheel will be 2.5 Nm × 10.0 s × 2.0 kg m2 = 50 kg m2/s.

1. Determine the angular momentum of the flywheel:

Angular momentum = Torque × Time × Moment of Inertia

= 2.5 Nm × 10.0 s × 2.0 kg m2

= 50 kg m2/s

The angular momentum of an object can be determined from the product of the applied torque, the time interval, and the moment of inertia. The moment of inertia is the rotational inertia of an object, which is the resistance to changes in its angular velocity. The angular momentum of the flywheel in this question is equal to the product of the applied torque, the time interval, and the moment of inertia. Therefore, the angular momentum of the flywheel will be 2.5 Nm × 10.0 s × 2.0 kg m2 = 50 kg m2/s. This means that the flywheel will have an angular momentum of 50 kg m2/s after the 10-second interval when the torque is applied.
