Similar triangles are two or more triangles that have common properties of their corresponding sides. Though the triangles are not congruent.

From the given question,

i. The side of ΔNMQ that corresponds to side Y is NQ.

ii. Comparing ΔNMQ and ΔOPM, we have;

Answer:

No, because the remainder is not equal to zero.

Answer:1

Step-by-step explanation:

By adding up all the positive real numbers, one may determine the domain of a logarithmic expression.

A logarithm is a measurement of the amount that a fixed number (the base) must be increased in order to create a particular number.

Basically,

if y=ax

So, logₐ(y) = x

The base of the logarithm in this instance is a. The following two bases are frequently employed: base-10 and Base-e

'e' is a mathematical constant having a value of around 2.718.

If the base is "e," we use a specific expression: ln(x)

Fundamentally,

ln(x)=loge(x)  

Here, e is the base.

Base-10 will be used if no base is provided, as in the formula

log(x)=log10(x)

Here 10 is the base

The domain of a function is the set of all input values (sometimes referred to as independent variables) for which the function is defined and produces an acceptable result (also called dependent variable). Most often, the domain is represented by a collection of numbers or a range of numbers.

The term "range" refers to the entire set of potential output values (dependent variable) that a function can produce for any set of valid input values inside its domain. Usually, a group of numbers or a range of numbers is used to represent the range.

The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

Now, According to the question:

What is horizontal line?

A horizontal line is a straight line that is parallel to the x-axis and where all the points on the line have the same y-coordinate. Are all horizontal lines in 2-D shapes parallel? Yes, all horizontal lines are parallel to each other. Horizontal lines, when extended, never intersect with one another.

Hence, The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

An operation that fills in the blank to make the equation a true statement is addition (+).

In order to determine the required mathematical operation that would make the equation a true statement, we would apply the distributive property of multiplication to the left-hand side (LHS) of the given equation.

By applying the distributive property of multiplication to the given mathematical expression, we have the following:

Left-hand side (LHS) = 5(1/2q + 3r - 4s) - 9r

Left-hand side (LHS) = 5/2q + 15r - 20s - 9r

By collecting like terms, we have the following mathematical expression:

Left-hand side (LHS) = 5/2q + (15r - 9r) - 20s

Left-hand side (LHS) = 5/2q + 6r - 20s

A linear function is a function that represents a straight line when plotted on a coordinate plane.

A linear function is a function that has a constant rate of change and can be represented by a straight line when plotted on a coordinate plane. The equation for a linear function is usually written in the form y = mx + b, where m is the slope and b is the y-intercept. The slope indicates how much the y-value changes when the x-value increases by one unit, and the y-intercept indicates the value of y when x is equal to zero.

When we imply that a linear function has a constant rate of change, we also mean that the rate of change of the output (y-value) with respect to the input (x-value) is always the same.

Linear functions can be used to model many everyday situations such as population growth, speed, distance, and temperature. Linear functions are also used in mathematics to solve equations, calculate slopes, and determine the area under a curve.

Answer: a = -24

Step-by-step explanation:

For this problem, we need to solve for a:

30 = 26 - a/6

lets subtract 26 from both sides

f to the negative 1 means the inverse function of a given function "f"

In mathematics, the notation "f^-1" (or "f to the negative 1 power") is used to indicate the inverse function of a given function "f".

A function "f" maps an input (also called the domain) to an output (also called the range). An inverse function "f^-1" maps the output of the original function back to its corresponding input.

In other words, if f(x) = y, then f^-1(y) = x.

For example, consider the function f(x) = 2x. The inverse function of f is f^-1(x) = x/2. The original function maps the input x to the output 2x, and the inverse function maps the output back to the input x/2.

Note that for a function to have an inverse function, it must be a one-to-one function. which means that for every unique output, there must be a unique input.

In summary, the notation "f^-1" represents the inverse function of a given function "f", which maps the output of the original function back to its corresponding input.

Logarithmic functions are inverse of exponential functions and describe the relationship between two variables when one increases or decreases at a constant rate. Exponential functions are functions where the variable increases or decreases at a rate that is proportional to its current value.

Logarithmic functions are inverse of exponential functions and describe the relationship between two variables when one increases or decreases at a constant rate. This means that the logarithm of a number is equal to the exponent to which another fixed number, the base, must be raised to produce that number. For example, the logarithm of 1000 to base 10 is 3, because 10 to the power of 3 is equal to 1000. Exponential functions are functions where the variable increases or decreases at a rate that is proportional to its current value. An example of this is a population growth function, where the population size increases exponentially with time. The equation for an exponential function is y=ab^x, where a is the initial value, b is the base and x is the exponent. The exponential function can also be written in logarithmic form, which is log_b(y)=x. In this form, the base number is fixed, and the exponent is being found. This can be used to solve for x.
