Points of discontinuity for the rational function y=(x+3)(x-5)(x+7)/(x+1)(x+4) are x = -1 and x = -4.

A rational function is a function that can be expressed as the ratio of two polynomial functions. In the case of the given rational function y=(x+3)(x-5)(x+7)/(x+1)(x+4), the numerator is a polynomial of degree 3, and the denominator is a polynomial of degree 2.

To find any points of discontinuity for a rational function, we need to determine where the denominator is equal to zero. Division by zero is undefined, so any value of x that makes the denominator equal to zero will be a point of discontinuity for the function.

In this case, we set the denominator (x+1)(x+4) equal to zero and solve for x:

(x+1)(x+4) = 0

This equation is true if either (x+1) = 0 or (x+4) = 0. So we have two solutions:

x+1 = 0 or x+4 = 0

x = -1 or x = -4

These values of x make the denominator of the function equal to zero, which means that the function is undefined at these points. These points are known as vertical asymptotes of the function, since the function approaches infinity as x approaches these points from either side.

It's important to note that the numerator of the function does not affect the points of discontinuity, since it is always defined for any value of x. Therefore, the points of discontinuity only depend on the denominator of the function.

The number of children who like both pistachio and chocolate ice cream is 73.

Here we have to find at least one kind of ice cream liked by the children.

It is given that the total number of children is 395. The number of children who don't like any ice cream is 170.

So we get the number of students who like one or both the ice cream is 395 - 170 = 225.

Here it is provided that 123 children like pistachio ice cream and 175 children like chocolate ice cream.

So the total number of children who like pistachio and chocolate ice cream is 175+ 123 = 298. Which cannot be greater than 225.

So the number of children who like both ice creams is 298 - 225 = 73.

The correct transformation(s) that can be used to map one triangle onto the other are:

1. Translation only

2. Rotation, then translation

Both triangles have congruent sides J K, K L, L M, and M J. To map one triangle onto the other, we can apply a translation, which simply moves the entire triangle in a specific direction, without changing its shape or size.

Alternatively, we can also apply a rotation, followed by a translation, to map one triangle onto the other. This involves rotating one triangle around a fixed point, and then moving it to its final position using a translation. Since the triangles are congruent by SSS, we can use the fact that the corresponding sides are equal in length to determine the amount of rotation needed. The fixed point could be any point, such as the midpoint of KL.

Therefore, the correct transformation options are translation only and rotation, then translation.

The slope intercept form is y = mx + c.

A line with m as its slope, m as its y-intercept, and c as its coefficient makes up the graph of the linear equation y = mx + c. The values of m and c in this version of the linear equation—known as the slope-intercept form—are real numbers.

The steepness of a line is indicated by the slope, m. Sometimes, the term "gradient" is used to refer to the line's slope. The point on a line's graph where it meets the y-axis is designated by the y-coordinate, or b, as the line's y-intercept. The supplied line L's distance c is known as its y-intercept.

Therefore, the coordinate of the point where the line L intersects the y-axis will be (0, c).

As a result, line L has a slope of and passes through the fixed point (0, c).

A measure that results in drastically different ratings over time lacks test-retest reliability.

Test-retest reliability refers to the consistency of measurements taken over time. If a measure results in drastically different ratings over time, it indicates a lack of consistency and therefore, a lack of test-retest reliability. This means that the measure is not dependable or accurate in measuring what it intends to measure. For example, if a survey measuring job satisfaction is administered to the same group of employees at two different time points, and the results show a significant difference, it may be due to a lack of test-retest reliability. In this case, the survey may need to be revised or replaced with a more reliable measure.

Test-retest reliability is crucial in ensuring the accuracy and dependability of a measure. A lack of test-retest reliability can lead to inaccurate results and can undermine the validity of the measure.

Answer:

54°

Step-by-step explanation:

We know that a flat line= 180° and ∠ABC is 90° which means 2x+2x+x=90°.

Therefore, 5x=90° so x=18°

18*3=54 so your answer is 54°

3x = 54°

The correct option is (C).

An angle is a form of geometrical shape, that is constructed by joining two rays to each other at their end-points. The angle can also be represented by three letters of the shape that define the angle, with the middle letter being where the angle actually is (i.e.its vertex). Angles are generally represented by Greek letters such as θ, α, β, etc.

Given,

In the figure

∠CBA = 90°

and

∠CAB + ∠CBD = 180°

Putting the value by the given figure

90° + x + 2x + 2x = 180°

5x = 180° - 90°

5x = 90°

x = 90° / 5

x = 18°

⇒ 3x = 3 × 18°

⇒ 3x = 54°

Hence, the value of 3x = 54°

The purpose of a variable is to hold and represent a value Option C.

The purpose of a variable in programming or mathematics is to hold and represent a value that can be assigned, changed, and used in various operations or calculations. Variables are fundamental components of programming languages and mathematical equations, enabling flexibility and dynamic behavior in computational tasks.

Option (c) "to hold a value" is the most accurate answer, as variables are used to store data or information in memory locations. This value can be of different types, such as integers, floating-point numbers, characters, or even more complex data structures like arrays or objects.

Variables allow programmers to work with and manipulate data efficiently. By assigning values to variables, we can reference and modify them throughout the program, making it easier to manage and organize information.

Variables also play a crucial role in performing calculations, as mentioned in option (b). We can use variables in mathematical expressions and algorithms to perform arithmetic operations, comparisons, and other computations. By storing values in variables, we can reuse them in multiple calculations and update them as needed.

While option (a) "to assign values" is a specific use case of variables, it is not the sole purpose. Variables not only store values but also facilitate data manipulation, control flow, and the implementation of algorithms and logic.

Option (d) "to hold a constant value" is incorrect because variables, by definition, can hold varying values. Constants, on the other hand, are fixed values that do not change during the execution of a program. Option C is correct.

Answer:

yes he is

Step-by-step explanation:

In a competitive market, we need to graph the market demand and supply curves and determine the equilibrium quantity. The equilibrium quantity represents the quantity at which the demand and supply curves intersect.

To sketch the supply and demand curves, we first need to gather information on the market demand and supply. The demand curve represents the quantity of ventilators that the four hospitals are willing to purchase at different prices, while the supply curve represents the quantity of ventilators that the four producers are willing to sell at different prices.

Using the multipoint drawing tool, we can plot the market demand curve based on the data provided for the hospitals. Label this line as 'Demand'. Next, using the same tool, we can plot the market supply curve based on the data provided for the producers. Label this line as 'Supply'.

The equilibrium quantity is determined at the point where the demand and supply curves intersect. It represents the quantity of ventilators that will be sold in the market. To find this point, we identify the quantity at which the demand and supply curves meet on the graph.

By following the instructions and accurately plotting the demand and supply curves, we can determine the equilibrium quantity of ventilators sold in the market.
