We assume that the table represents the complete definitions of the functions of interest.

An x-intercept is a point where the y-value is 0. Only f(x) includes such a point: (-3, 0).

A y-intercept is a point where the x-value is 0. x=0 is not part of the domain of any of these functions, so there are no y-intercepts.

The maximum values of these functions are ...

so h(x) has the greatest maximum value.

The range of each function is the list of its table values. No two functions have the same range.

The domain of each function is the set of x-values for which it is defined. All of these functions have the same domain. That is, they are all defined for all of the x-values listed.

If a triangle is equilateral, then it has three congruent angles.

In logic and mathematics, contraposition refers to the inference of going from a conditional statement into its logically equivalent contrapositive, and an associated proof method known as proof by contraposition. The contrapositive of a statement has its antecedent and consequent inverted and flipped.

Conditional statement : P → Q .

In formulas the contrapositive of P→ Q is ¬ Q → ¬P.

If P, Then Q. — If not Q, Then not P. "If it is raining, then I wear my coat" — "If I don't wear my coat, then it isn't raining."

The law of contraposition says that a conditional statement is true if, and only if, its contrapositive is true.

In mathematics, the definition of congruent angles is "angles that are equal in the measure are known as congruent angles". In other words, equal angles are congruent angles. It is denoted by the symbol "≅", so if we want to represent ∠A is congruent to ∠X, we will write it as ∠A ≅ ∠X.

An equilateral triangle is a triangle with all three sides of equal length a, corresponding to what could also be known as a "regular" triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal. An equilateral triangle also has three equal 60 degrees angles.

Therefore, based on above introductions we can say that If it is an equilateral triangle, then the triangle has three congruent angles.

Figure (a)

The similar triangles in this figure are

ABC and AED

This is because:

The triangles have similar corresponding sides and congruent angles

Also, ABC is divided by 3 to get AED

Answer:

135 ft^3

Step-by-step explanation:

Volume of a rectangular prism is basically just width x height x depth. So the area of the base multiplied by the height. 15 x 9 = 135

Answer: 135 ft³

Step-by-step explanation:

     Volume, when dealing with a rectangular prism, is L * W * H

-> L * W can simplify to the base, as it does in the problem given to us.

V = (L * W) * H

V = B * H

V = 15 * 9

V = 135 ft³

          The rectangular prism has a volume of 135 ft³.

To calculate the probability that the male line of descent of a particular husband will eventually die out, we can analyze the different scenarios.

A couple has exactly three children:

In this case, the male line of descent will not die out, as they have at least one boy.

A couple has more than three children, and the first-born child is a boy:

In this scenario, the male line of descent will continue, as they have at least one boy.

A couple has more than three children, and the first-born child is a girl:

In this situation, the male line of descent depends on the subsequent children. Each subsequent child has an equal chance of being a boy or a girl. If there are only girls born after the first child, then the male line of descent will eventually die out.

Since each child is equally likely to be a boy or a girl, the probability of having only girls after the first-born child is (1/2)^n, where n is the number of subsequent children.

Therefore, the probability that the male line of descent of a particular husband will eventually die out is the probability of scenario 3 occurring, which can be calculated by summing the probabilities of having only girls after the first-born child for different numbers of subsequent children.

However, the exact probability depends on the specific conditions and number of subsequent children, which is not provided in the question.

According to this property, when both sides of an equation are multiplied by the same real number, both sides of the equation always remain the same. The formula for this property can be expressed in real numbers a, b and c. If a × c = b × c.

Property of Equality:

The equivalence property describes the relationship between two equal quantities. If you apply a math operation to one side of the equation, you must also apply it to the other side of the equation to maintain balance.

That is, a property that does not change the truth value of an equation or does not affect the equivalence of two or more quantities is called an equality property. These equality properties help solve various algebraic equations and define equivalence or equilibrium relationships.

Multiplicative Property of Equality:

According to this property, when both sides of an equation are multiplied by the same real number, both sides of the equation always remain the same.

The formula for this property can be expressed as for the real numbers a, b, and c.

According to the Pythagorean theorem, "in a right-angled triangle, the squares of the hypotenuse side is equivalent to the sum of squares of the other two sides," the hypotenuse side is the longest side of the triangle.

This is further explained below.

Generally, The Pythagorean theorem is a well-known geometric theorem that states the number of squares just on the legs of a right triangle is equal to the square just on the hypotenuse (the side that is opposite the right angle).

This theorem can also be expressed in the familiar algebraic notation of a2 + b2 = c2, where a and b are the lengths of the legs of the triangle.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is an essential connection in Euclidean geometry that describes the relationships between the three sides of a right triangle.

It indicates that the total of the areas of the squares on the other two sides is equal to the area of the square whose side is the hypotenuse.

In conclusion, This means that the area of the square whose side is the hypotenuse is equal to that amount.

Step-by-step explanation:

The Length of the conjugate axis is equal to 2b. The transverse axis is an essential feature of a hyperbola, as it determines the overall shape of the hyperbola.

In a hyperbola, the name of the green segment is called the transverse axis. The transverse axis is the longest distance between any two points on the hyperbola, and it passes through the center of the hyperbola. It divides the hyperbola into two separate parts called branches.

The transverse axis of a hyperbola lies along the major axis, which is perpendicular to the minor axis. Therefore, it is also sometimes called the major axis.

The other axis of a hyperbola is called the conjugate axis or minor axis. It is perpendicular to the transverse axis and passes through the center of the hyperbola. The length of the conjugate axis is usually shorter than the transverse axis.In the hyperbola above, the green segment is the transverse axis, and it is represented by the letters "2a". Therefore, the length of the transverse axis is equal to 2a.

The blue segment is the conjugate axis, and it is represented by the letters "2b".

Therefore, the length of the conjugate axis is equal to 2b.The transverse axis is an essential feature of a hyperbola, as it determines the overall shape of the hyperbola. In particular, the distance between the two branches of the hyperbola is determined by the length of the transverse axis.

If the transverse axis is longer, then the branches of the hyperbola will be further apart, and the hyperbola will look more stretched out. Conversely, if the transverse axis is shorter, then the branches of the hyperbola will be closer together, and the hyperbola will look more compressed.

What is an algebraic expression?

An expression that includes variables, constants, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, etc.). Terms combine to form expressions.

With the help of integer constants, variables, and the addition, subtraction, multiplication, and division operations in basic arithmetic, an algebraic expression is created. The algebraic statement 5x + 6 is an illustration. In this case, 5 and 6 are fixed values, while x is a variable. Additionally, the variables can be either simple variables with alphabets like x, y, or z or complex variables with names like x², x³, etc. Polynomials are another name for algebraic expressions.
