Answer:

12x^2 - 13x + 3 is a quadratic equation in the standard form ax^2 + bx + c, where a = 12, b = -13, and c = 3. This equation can be factored, completed the square or used the quadratic formula to find the solutions of x.

All rational functions can be expressed as f(x)=p(x)/q(x), where p and q are polynomial functions and q(x) cannot be equal to 0.

All rational functions can be expressed as f(x) = p(x)/q(x), where p and q are polynomial functions and q(x) ≠ 0.

Rational function is the ratio of two polynomial functions where the denominator polynomial is not equal to zero. It is usually represented as R(x) = P(x)/Q(x), where P(x) and Q(x) are polynomial functions. In past grades, we learnt the concept of the rational number. It is the quotient or ratio of two integers, where the denominator is not equal to zero. Hence, the name rational is derived from the word ratio

Answer:

Step-by-step explanation:

Since this is a right triangle we will use trig identites and ratios to solve. x first. The side opposite the reference angle of 22 degrees is 6, and the hypotenuse is x. The trig ratio that uses the side opposite over the hypotenuse is the sin ratio:

\(sin22=\frac{6}{x}\) and

\(x=\frac{6}{sin22}\) so

x = 16.01

Now for y. y is adjacent to the reference angle, and the trig ratio that uses the side opposite over the side adjacent is the tangent ratio:

\(tan22=\frac{6}{y}\) and

\(y=\frac{6}{tan22}\) so

y = 14.85

The feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

To determine whether the feasible set for each system of constraints is convex, we need to analyze the constraints individually and examine their intersection.

a) (x1)² + (x2)² > 9

This constraint represents points outside the circle with a radius of √9 = 3. The feasible set includes all points outside this circle.

b) x1 + x2 ≤ 10

This constraint represents points that lie on or below the line x1 + x2 = 10. The feasible set includes all points on or below this line.

c) x1, x2 > 0

This constraint represents points in the positive quadrant, where both x1 and x2 are greater than zero.

Now, let's analyze the intersection of these constraints:

Considering the first two constraints (a and b), we can see that the feasible set consists of all points outside the circle (constraint a) and below or on the line x1 + x2 = 10 (constraint b).

To determine whether the feasible set is convex, we need to check if any two points within the set create a line segment that lies entirely within the set.

If we consider the points (5, 5) and (3, 7), both points satisfy the individual constraints (a) and (b). However, the line segment connecting these two points, which is the line segment between (5, 5) and (3, 7), exits the feasible set since it passes through the circle (constraint a) and above the line x1 + x2 = 10 (constraint b).

Therefore, the feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

The transformation that would accomplish the proof that △ADB ≅ △CDB is; A) reflection of △CDB about diagonal BD

We are told that Lacy is given a  kite with one diagonal and she wants to prove that △ADB ≅ △CDB with the aid of verifying that corresponding pairs of sides and corresponding pairs of angles are congruent using just one rigid transformation.

Now, a rigid transformation is defined as a geometric transformation of a Euclidean space that preserves the Euclidean distance that exists between every pair of points. These rigid transformations could either be rotations, translations or reflections.

Now, in this case the quickest way to verify that corresponding pairs of sides and corresponding pairs of angles are congruent is to find a way to map both triangles to each other. The best way to achieve this will be a reflection of △CDB about diagonal BD

The mode best represents the set of data: red, blue, red, yellow, red, green, black, red, white, red. The mode is a statistical measure that represents the most frequently occurring value or values in a dataset.

The mode is the measure of center that represents the most frequently occurring value in a dataset. In this case, the color "red" appears most frequently, occurring 6 times out of the 11 data points. Therefore, the mode of the dataset is "red."

The mean, on the other hand, calculates the average value by summing all the data points and dividing by the total number of data points. The mean can be influenced by extreme values or outliers, which may not accurately represent the overall data.

The median is the middle value when the data is arranged in ascending or descending order. In this case, since there are 11 data points, the median would be the sixth value. However, there is no clear middle value as there are multiple occurrences of "red" in the dataset.

Hence, the mode, representing the most frequently occurring value, is the measure of center that best represents this set of data.

The term that describes a group of statements that executes as a single unit is a "block". A block of code is a program that is grouped together and treated as a single unit. So, the correct option is D.

In computer programming, a block is a group of statements or declarations that are enclosed within a set of curly braces ({ }). The block serves as a single unit that is executed together. Blocks are used to organize code and to apply control structures, such as loops and conditional statements, to multiple statements.

A block can contain any number of statements, which can include variable declarations, function calls, loops, conditional statements, and other constructs. The statements within a block are executed in sequence, one after another, unless a control statement is encountered that alters the normal sequence of execution.

For example, a while loop in Java consists of a block of code that is executed repeatedly while a certain condition is true:

while (condition) {

   // block of code to be executed while condition is true

}

In this example, the block of code inside the curly braces will be executed repeatedly while the condition specified in the while statement is true. The block can contain any number of statements, and these statements will be executed each time the loop iterates.

Another common use of blocks is to define functions or methods. A function or method is a block of code that can be called from other parts of the program, and can take inputs (arguments) and return outputs. For example, in Python, a function can be defined as follows:

def function(argument1, argument2):

   # block of code to be executed in the function

   return result

In this example, the block of code enclosed within the function definition is executed when the function is called. The function can take inputs (argument1 and argument2), which can be used within the function, and it can return a result using the return statement.

the distance from the plane to the radar station is increasing at a rate of approximately 30.84 kilometers per minute.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given, A plane flying with a constant speed of 25 km/min passes over a ground radar station at an altitude of 12 km and climbs at an angle of 30 degrees.

We can use the law of cosines to find d:

d² = 12² + (h + 12)² - 2(12)(h + 12)cos(θ)

Since the plane is climbing at an angle of 30 degrees, we can use trigonometry to find h:

sin(30) = h / (25 km/min * 2 min)

h = 25 km/min

Now we can substitute this value of h into the equation for d and simplify:

d² = 12² + (25 + 12)² - 2(12)(25 + 12)cos(θ)

d² = 12² + 37² - 2(12)(37)cos(θ)

d² = 144 + 1369 - 888cos(θ)

d² = 1513 - 888cos(θ)

To find the rate at which d is changing, we can take the derivative of both sides of this equation with respect to time:

2dd/dt = -888(d(cos(θ))/dt)

Since the plane is flying with a constant speed of 25 km/min, we can use trigonometry to find d(cos(θ))/dt:

cos(θ) = 12/d

d(cos(θ))/dt = -(12/d²)(dd/dt)

d(cos(θ))/dt = -(12/d²)(25 km/min)

Now we can substitute these values into the equation for the rate of change of d:

2dd/dt = -888(-(12/d²)(25 km/min))

2dd/dt = (888*12)/(d²)(25 km/min)

dd/dt = (5328)/(d²) km/min

Finally, we can substitute the value we found for d into this equation to get the rate at which d is changing 2 minutes later:

d = sqrt(1513 - 888cos(θ))

θ = 30 degrees

dd/dt = (5328)/(d²) km/min

dd/dt = (5328)/(1513 - 888cos(30)) km/min

dd/dt ≈ 30.84 km/min

Therefore, the distance from the plane to the radar station is increasing at a rate of approximately 30.84 kilometers per minute.

How to calculate percentage and how is it determined?
A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. So, a part per hundred is what the percentage refers to. Percent signifies for every 100. The sign "%" is used to denote it. No dimension exists for percentages. Thus, it is referred to as a dimensionless number. The value must be divided by the entire value, and the resulting number must then be multiplied by 100 to get the percentage.
Mathematically, Percentage formula = (Value/Total value) × 100

Given, cost price of hat (total value) = $ 15.99
Percentage tax imposed on the hat = 6%
Now, using the formula established in the literature above, we have:
Percentage = (Value/Total Value)×100
⇒ Value = (Percentage × Total Value)/100 = (6×15.99)/100 = $ 0.9594
Therefore, the total price of hat = Cost Price + Value = $ (15.99 + 0.9594) = $ 16.9494
Thus, the total price of the hat including the tax is $ 16.9494 .

Step-by-step explanation:

For easier computation convert hours minutes to all minutes as follows:
h hours and m minutes = (h x 60 + m) minutes

Peter read the most for3 hours

3 hours = 60 x 3 = 180 minutes

Lane read for 47 minutes less than Peter
Time that Lane spent on reading = 180 - 47 = 133 minutes

Molly spent 1 hour and 19 minutes less than Lane spent on reading
1 hour and 19 minutes = 1 x 60 + 19 = 79 minutes

So Molly spent 79 minutes less than Lane on reading
Actual time Molly spent on reading = 133 - 79 = 54 minutes

You would use a histogram to illustrate data for a variable measured at the interval/ratio scale of measurement.

A histogram is a type of graph that uses adjacent rectangles to depict the distribution of continuous numerical data.

A variable is a feature or property that can take on several different values. In the research context, a variable can be described as anything that may have an effect on the outcome of a study or research project.

Variables can be classified according to the scale of measurement, which is a mathematical categorization of the nature of variables that have been measured. There are four different levels of measurement: nominal, ordinal, interval, and ratio.

Nominal data describes categories that cannot be ordered, while ordinal data describes categories that can be ordered. Interval data measures differences between variables, but there is no true zero point. On the other hand, ratio data has a true zero point and describes the ratio of two variables.

Therefore, histograms are used to illustrate data for a variable measured at the interval/ratio scale of measurement.
