(Option D.) The Side-Side-Side (SSS) Theorem: If three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.

The Side-Side-Side (SSS) Theorem is a valid theorem to show that two triangles are congruent. This theorem states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.

In other words, if all three of the sides of one triangle are equal in length to all three of the sides of another triangle, then the two triangles are identical in size and shape. This theorem is a fundamental building block of geometry, and is often used to prove the congruence of two triangles in proofs or mathematical arguments.

Answer:

Step-by-step explanation:

The vector representing the path of the ship from port A to the refueling station has components <14, 23>, and the vector representing the path from the refueling station to port B has twice the magnitude as the vector from port A to the refueling station.

To find the characteristics of the vector representing the path of the ship from port A to port B, we can add the two vectors together.

The sum of two vectors <a, b> and <c, d> is given by <a+c, b+d>. Therefore, the vector representing the path of the ship from port A to port B is given by:

<14, 23> + 2*<14, 23> = <14+214, 23+223> = <42, 69>

The vector representing the path of the ship from port A to port B is <42, 69>. This vector has a magnitude of √(42^2 + 69^2) = √(1764 + 4761) = √(6525) = 81 and a direction given by the angle theta, where tan(theta) = 69/42.

There are a total of 50 odd numbers between 1 to 100.

1 is the smallest, odd number:

The sum of all the odd numbers from 1 to 100 is 2500.

The average or mean of all odd numbers 1 to 100 is 50.

[tex]\boxed{ 3 + 2 = 5, 5 + 2 = 7, 7 + 2 = 9}[/tex]

The last number in the chart of odd numbers 1 to 100 given below is 99, as, if we add 2 to 99, we will get 101 which is greater than 100. So, 99 is the last odd number in the list of odd numbers from 1 to 100.

Therefore, the odd integers from 1 to 100 is 99

A picture is given below of all the odd numbers of 1 to 100:

The equation for the total square yards of cloth she needs for both pillows is 314+112=426.

The total number of square yards of fabric Lea needs for both pillows is the sum of the fabric needed for the first pillow and the fabric needed for the second pillow. This can be represented by the expression:

314 square yards + 112 square yards = 426 square yards

Therefore, the expression that represents the total number of square yards of fabric Lea needs for both pillows is:

314 + 112 = 426

This expression would simplify to 426 square yards. This expression uses the addition operator (+) to add the two quantities of fabric that Lea needs for each pillow. The result is the total number of square yards of fabric that she needs for both pillows.

The region encircled by a circle with radius r is known as πr² in geometry. Here, the Greek letter stands for the constant proportion of a circle's circumference to its diameter, which is roughly equivalent to 3.14159.

This formula, which was first discovered by Archimedes, can be derived by considering the circle as the boundary of a series of regular polygons. A regular polygon's area is equal to half its perimeter times the distance from its center to its sides. The equivalent formula,  [tex]A=\frac{1}{2} *2\pi r*r[/tex] states that the area is equal to half the perimeter times the radius.

The limit for a circle is held by [tex]\pi r^{2}[/tex].

Given;

1) r=12.5m

[tex]A=\pi r^2=\pi (12.5)^2=490.873m^2[/tex]

The multiplicity of 0 is the number of times that 0 appears as a root of a polynomial equation.

In other words, it is the number of times that 0 is a solution to the equation. For example, the equation x^2 - 4x + 4 has two solutions, 0 and 4. The multiplicity of 0 is therefore 2, since 0 is a repeated solution.

If a polynomial equation has only one 0 as a solution, the multiplicity of 0 is 1. In some cases, a polynomial equation may have no 0s as a solution, in which case the multiplicity of 0 is 0.

In general, the multiplicity of a number is the number of times it appears as a solution to a polynomial equation. For example, the equation x^2 - 2x + 8 has two solutions, 2 and 4. The multiplicity of 2 is 1, since 2 appears only once as a solution, while the multiplicity of 4 is 2, since 4 appears twice as a solution.

The length of the third side of an isosceles triangle with sides 4 cm and 10 cm is 10 cm.

We know that in an isosceles triangle, two sides are equal.

One side of the triangle is 4 cm and the other is 10 cm.

Let us consider the third side to be 4 cm,

then 4 cm + 4cm = 8 cm and it is not greater than the third side 10 cm.

Hence, the third side cannot be 4 cm.

Then the third side can be 10 cm,

A function increases if the output value of function increases on increasing the input value and the function decreses if the output value of function decreases on increasing the input value

As we know a function is nothing but a relation between input values and output values where each input has exactly one output.

Consider a function y = f(x)

For a given function if the value of y increases on increasing the value of x, then the function is an increasing function

If the y-value decreases on increasing the value of x, then the function is a decreasing function.

Another method is that if we need to determine whether a function f(x) is increasing or decreasing at point 'a'.

If a function is differentiable on an open interval, we calculate the derivative of function f(x)

If the derivative f′(x) > 0 on an open interval, then function f(x) is increasing on that interval.

If the derivative f′(x) < 0 on an open interval, then function f(x) is decreasing on that interval.

Therefore, if the output value of function increases on increasing the input value then the function is an increasing function and if the output value of function decreases on increasing the input value then the function is an decreasing function.

The y-intercept of the equation 2x - y = -3 is 3 and in ordered pair form is (0,3).

The slope-intercept formula is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the equation in the question

2x - y = -3

First, we solve form for y and reorder in slope intercept form.

2x - y = -3

Subtract 2x from both sides

2x - 2x- y = -3 - 2x

- y = -3 - 2x

Divide each term by -1

y = 3 + 2x

Reorder in slope intercept form

y = 2x + 3

To find the y-intercept, replace x with zero and solve for y

y = 2(0) + 3

y = 3

Therefore, the y-intercept is 3.
