In a consistent system with more variables than equations, the augmented column of the reduced row echelon form (rref) contains the solution set of the system of linear equations.

The Reduced Row Echelon Form denoted as "rref"  is a matrix representation of the system in which the leading non-zero entry in each row is 1 and is called the pivot. The pivots in the rref correspond to the basic variables in the solution set, and the non-pivot variables are free variables.

In the augmented column of "rref" , the entries corresponding to the pivot columns give the values of the basic variables in the solution set, while the entries corresponding to the non-pivot columns give the coefficients of the free variables,  free variables can take any value and do not affect the solution set,

Therefore, information contained in augmented column of the rref gives the values of the basic variables and the coefficients of the free variables in the solution set of the system.

Mr. Estes paid $136,000 for the SUV after the discount was applied.

Markdown percentage is defined as the decrease in the price which is calculated as a percent of the selling price.

We have the formula,

Selling price = (1 - markdown rate) Original price

Here,

Markdown percentage = 15%

Markdown rate = 15/100 = 0.15

Original price of the car = $160,000

Selling price = (1 - 0.15) × 160,000

                     = 0.85 × 160,000

Answer:

x = 12.5 degree

y = 220 degree

Step-by-step explanation:

The 1/2y is equal to the 110-degree angles, so to find the y, we take

110 times 2 = 220. So, the answer for y is 220.

The (4x + 20) and 1/2y must add up to 180 degrees. We know one is 110 degrees, so the (4x + 20) must be equal to 70 degrees.

4x + 20 = 70

4x = 50

x = 12.5 degree

So, x = 12.5 degrees and y = 220 degrees.

The radius sign () with a little three (3) above it, followed by the number, can be used to represent a number's cube root. For instance, 8's cube root is represented by the symbol 8.

The number that remains the same after being multiplied twice by itself is known as a number's cube root. It can be written as the radical sign () followed by the number and a little three (3) above it. For instance, 8's cube root is represented by the symbol 8. When 8 is multiplied by itself twice (8 x 8 x 8), the result is 8; this is known as "the cube root of 8." In a similar way, 27's cube root can be expressed as 27, which, when multiplied by itself twice, also equals 27. Exponential expressions can also be used to represent cube roots. Because 8's cube root is expressed as 23, the result of multiplying 8 by itself three times (2 x 2 x 2) is also 8. Similarly, 33 can be used to represent the cube root of 27.

The final distance of the port from the ship is 75.63 km and the final bearing of the port from the ship is 263.57° using cosine and sine rules.

Considering the triangle formed by the ship ∆ABC where A, B and C are the points for; the port, where the ship changes its course, and its final bearing. The final distance "a" of the port from the ship is calculated with cosine rule as follows;

a² = b² + c² - 2(b)(c)cosA

a² = 40² + 70² - 2(40)(70)cos82°

a² = 1600 + 4900 - 5600cos82°

a² = 5720.63 {take square root of both sides}

a = 75.63

For the triangle ABC, by sine rule;

a/sinA = b/sinB = c/sinC

75.63/sin82° = 70/sinC

C = sin⁻¹(70 × sin82°/75.63) {by cross multiplication}

C = 66.43

angle C = 60 + 6.43 {60° is an alternate angle with angle 30° at the point B where the ship chenged course and 6.43° is a complementary angle at the 3rd quadrant of point C}

The final bearing of the port from the ship is calculated as;

180° + (90 - 6.43)° = 263.57°

Answer:

x = arccos(sqrt((1 + sin(x))/2)) + 2npi or x = pi - arccos(sqrt((1 + sin(x))/2)) + 2npi

Step-by-step explanation:

cos^2(x) - sin^2(x) = sin(x) can be rewritten as cos^2(x) = sin^2(x) + sin(x)

Using the identity sin^2(x) + cos^2(x) = 1, we can simplify the equation as

cos^2(x) = 1 - cos^2(x) + sin(x)

Solving for cos^2(x), we get

cos^2(x) = (1 + sin(x))/2

Therefore, cos(x) = sqrt((1 + sin(x))/2) or cos(x) = -sqrt((1 + sin(x))/2)

To find the possible values of x, we need to find the values of sin(x) that satisfy this equation.

For the domain [0, 2pi), the range of sin(x) is [-1, 1], so we have:

cos(x) = sqrt((1 + sin(x))/2) for -1 <= sin(x) < 1

cos(x) = -sqrt((1 + sin(x))/2) for -1 <= sin(x) < 1

So, the solution is

x = arccos(sqrt((1 + sin(x))/2)) + 2npi or x = pi - arccos(sqrt((1 + sin(x))/2)) + 2npi

A population is any large group that has at least one resource is common. People do not make up all populations. Population numbers can include, but aren't limited to, people, animals, groups, organizations, buildings, houses, trucks, farms, and things.

Let's call the population after it has tripled "P_triple". Then:

P(t) = 3P(0) = 3 * 95

P_triple = 285

We want to find the time t such that P(t) = 285, so we'll set the two expressions equal to each other:

95 (1.53)^t = 285

Dividing both sides by 95:

(1.53)^t = 3

Taking the natural logarithm of both sides:

t = log(3) / log(1.53)

Introduction:

Probability is a measure of the likelihood that a given event will occur. In this scenario, the event of interest is the fuel tank being empty, given the observation that the battery is flat. Evaluating the probability of this event involves finding the relationship between the fuel tank and the battery, and using this information to calculate the probability that the fuel tank is empty.

Detailed explanation:

To evaluate the probability of the fuel tank being empty given the observation that the battery is flat, we need to use Bayes' theorem. Bayes' theorem states that the probability of event A given event B can be calculated as follows:

P(A|B) = P(B|A) * P(A) / P(B)

Where P(A|B) is the probability of event A given event B, P(B|A) is the probability of event B given event A, P(A) is the probability of event A, and P(B) is the probability of event B.

In this scenario, event A is the fuel tank being empty, and event B is the battery being flat. To calculate the probability of the fuel tank being empty given the battery is flat, we need to find the values of P(B|A), P(A), and P(B).

Suppose we have the following information:

P(A) = 0.1 (the probability that the fuel tank is empty)

P(B|A) = 0.8 (the probability that the battery is flat given that the fuel tank is empty)

P(B) = 0.05 (the probability that the battery is flat)

Using these values, we can calculate P(A|B) as follows:

P(A|B) = P(B|A) * P(A) / P(B) = 0.8 * 0.1 / 0.05 = 0.16

This means that the probability that the fuel tank is empty given the battery is flat is 0.16.

In conclusion, the probability that the fuel tank is empty given that the battery is flat is lower than the probability that the fuel tank is empty, which was 0.1. This suggests that having a flat battery decreases the likelihood that the fuel tank is empty.
