Integer multiplication is equivalent to repetitive addition, which is adding an integer a predetermined number of times. For instance, adding 4 three times results in the number 12 (4 + 4 + 4).
What is an integer ?All whole numbers and negative numbers are considered integers.
This means that if we combine negative numbers with whole numbers, a collection of integers results.
An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion. Integers include things like -5, 0, 1, 5, 8, 97, and 3,043. Z is a representation of a collection of integers.
A straight line of numbers is shown visually as a number line.
This line is used to compare integers that are spaced equally apart on an infinite line that extends horizontally on both sides.
The collection of integers can be shown on a number line much like other sets of numbers.
Hence, Integer multiplication is equivalent to repetitive addition, which is adding an integer a predetermined number of times. For instance, adding 4 three times results in the number 12 (4 + 4 + 4).

What is the formula to find centre?
The general equation to find centre of a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
Centre of the CircleThe location of a moving point on a plane such that its separation from a stationary point on the plane remains constant or fixed is described as a circle. The centre of the circle is the name given to the fixed point
A circle's centre and radius make up its 2D shape. Knowing the circle's centre and radius allows us to draw any circle. The number of radii that a circle can have is unlimited. The intersection of all the radii constitutes the centre of a circle. It is also known as the centre of the circle's diameter.
Center of Circle FormulaThe general equation of a circle is another name for the centre of circle formula. If the radius is r, the center's coordinates are (h,k), and any point on the circle is (x,y), the centre of the circle formula is as follows:
(x - h)2 + (y - k)2 = r2
2 = r2

reflection across x = 4
F(3,-5), C(3,-4), P(5,-4)
Given:
Points F(3,-5), C(3,-4), P(5,-4)The triangle FCP is reflected across the line x = 4.
See the attached with both FCP and F'C'P' triangles shown.
The x-coordinates are 1 unit apart from the x = 4 line, hence the new coordinates are 2 units less or greater than the original one and the y-coordinates remain as is.
Reflected points:
F(3, -5) → F'(5, - 5)C(3, - 4) → C'(5, - 4)P(5, - 4) → P'(3, - 4)Answer:
F' = (5, -5)
C' = (5, -4)
P' = (3, -4)
Step-by-step explanation:
When an object is reflected over a vertical line, the x-value changes but the y-value does not change.
To reflect points across x = 4, determine the distance of the x-value of each of the points to the line of reflection by subtracting 4 from the x-values:
F: 3 - 4 = -1C: 3 - 4 = -1P: 5 - 4 = 1Point F is located 1 unit to the left of the line of reflection. Therefore, the reflection of this point is 1 unit to the right of the line of reflection. So the reflection of point F is 2 units to the right of point F:
F' = (3+2, -5) = (5, -5)As point C has the same x-value as point F, the x-value of its reflection in the line of reflection will be the same as point F:
C' = (3+2, -4) = (5, -4)Finally, point P is located 1 unit to the right of the line of reflection. Therefore, the reflection of this point is 1 unit to the left of the line of reflection. So the reflection of point P is 2 units to the left of point P:

What kind of circumstances would lead you to writing a function versus using a loop?
When utilising a loop, you cannot update something in the code or add a new feature. Instead, you use functions. Therefore, if you wish to modify the function you are re-calling, you should use a function rather than a loop.
When should you use a function vs a loop?Similar to how a loop represents a piece of code that we want to run repeatedly, a function represents a piece of code that may be called at any moment and executed. For example, in the source code's current location, a certain loop construct could only be executed once. A computer function known as a loop repeats a statement or condition based on predetermined boundaries. In all programming languages, the loop function has nearly the same logic and syntax.The primary purpose of the concept of function is to enable code reuse. It can be used for two separate things, such as repeatedly invoking the same function within a programme and allowing users to apply the same function to several contexts after it has been generated.To learn more about function refer to:

A cubic equation could have three real roots, similar to how a quadratic equation could have two. However, a cubic equation always has at least one real root, unlike a quadratic equation, which may not have any real solutions.
The x-intercepts of a function are its roots. The y-coordinate of a point on the x-axis is always zero. As a result, we set f (x) = 0 and solve the equation to discover the roots of a quadratic function.

Constant variance is the assumption in regression analysis that the standard deviation and variance of the residuals are constant for all values of the independent variables.
Constant variance is the assumption in regression analysis that the standard deviation and variance of the residuals are constant for all values of the independent variables.
Homogeneity of variances means the assumption that the variances of the random variables are constant. This homoscedasticity (that is, constant variances) assumption can be tested using the same diagnostics used for linear regression models.
All data usually consist of the dependent variable and the independent variable itself. Constant variance is about many linear regression assumptions. For example, if you have 325 rows, there should be at least one variance, possibly a constant. The next question is how to compare variables with appropriate variances. The basic fact is that when plotting between a single value and a predicted value, the resulting variance should be constant for the prediction error value.

Approximate the intervals where each function is increasing and decreasing.
Given is the parabola opening down.
It increases up to vertex and then decreases in value.
The vertex is at (3, 4) so the intervals are:
Increase: ( - ∞, 3],Decrease: [3, ∞).Answer:
Increasing: (-∞, 3)
Decreasing: (3, ∞)
Step-by-step explanation:
A function is increasing when the slope is positive (y gets bigger as x gets bigger).
A function is decreasing when the slope is negative (y gets smaller as x gets bigger).
From inspection of the given parabola, the turning point is (3, 4).
The function is increasing as the curve approaches the turning point.
The function is decreasing as the curve approaches infinity after the turning point.
Therefore, the intervals where the function is increasing and decreasing are:
Increasing: (-∞, 3)Decreasing: (3, ∞)Note: x = 3 is not included in the intervals, as the curve is not increasing or decreasing when x = 3. There is a turning point (stationary point) at x = 3 which means the slope is zero as this point. Therefore, the function is not increasing or decreasing when x = 3.

Why must the base of a logarithm be a positive real number not equal to 1?
The base of a logarithm must be a positive real number and not equal to 1 because logarithms are defined as the inverse operation of exponentiation. The base must be a positive real number to be able to raise it to the power of the argument and not equal to 1 to get a meaningful result.
The base of a logarithm represents the number that is being raised to a certain power to produce the argument of the logarithm. If the base of a logarithm is not a positive real number, it is not possible to perform this inverse operation.
For example, if the base of a logarithm is 0, it would mean that the argument of the logarithm is being raised to the power of 0, which is always 1. Therefore, the logarithm would be 0 for any argument, which does not provide any useful information.
The base of a logarithm must be a positive real number and not equal to 1 because it is not possible to raise 1 to any power to produce any value other than 1. Therefore, a logarithm with base 1 is not a meaningful concept.
