Angle bisector

An angle bisector is a line segment, ray, or line that divides an angle into two congruent adjacent angles.

Line segment OC bisects angle AOB above. So, ∠AOC = ∠BOC which means ∠AOC and ∠BOC are congruent angles.

Bisecting an angle with compass and ruler

In geometry, it is possible to bisect an angle using only a compass and ruler. To do so, use the following steps:

Things to know about an angle bisector

If a point lies anywhere on an angle bisector, it is equidistant from the 2 sides of the bisected angle; this will be referred to as the equidistance theorem of angle bisectors, or equidistance theorem, for short.

In the figure above, point D lies on bisector BD of angle ABC. The distance from point D to the 2 sides forming angle ABC are equal. So, DC and DA have equal measures.

Conversely, if a point on a line or ray that divides an angle is equidistant from the sides of the angle, the line or ray must be an angle bisector for the angle.

Based on the equidistance theorem, it can be seen that when the two sides that make up an angle are tangent to a circle, the line segment or ray formed by the angle's vertex and the circle's center is the angle's bisector.

In the diagram above, the two sides of the angle are tangent to the circle and, DC and DA are the distances from the center of the circle to the sides. DC and DA are also the radii of the circle. Since all radii of a circle have equal measure, line BD bisects the angle.

Angle bisector theorem

For a triangle, like the one in the diagram below, if the bisector of angle A intersects side BC at point D, the ratio of the lengths of AB to AC equals the ratio of the length BD to DC. This can be written as: [tex]\frac{AB}{AC}=\frac{BD}{DC}[/tex]

The point at which the three interior angle bisectors intersect is known as the incenter of the triangle. Referencing the diagram below, the three bisecting rays intersect at point D. Point D is the incenter of the triangle and is a point that is equidistant from the three sides of the triangle.

It is not possible to construct a triangle whose sides are 5.5 cm 4.5 cm and 10 cm because the sum of two sides are equal to three sides. The equal sides cannot form a triangle.

In the given question, we have to check that it is possible to construct a triangle whose sides are 5.5 cm 4.5 cm and 10 cm.

To check whether the given sides can make a triangle or not, we have to check that the sum of two sides always grater than the third side.

To check this we firstly add the 5.5 and 10

5.5 + 10 > 4.5

15.5 > 4.5

Now we add 4.5 and 10

4.5 + 10 > 5.5

14.5 > 5.5

Now we add 5.5 and 4.5

5.5 + 4.5 = 10

10 = 10

The least common denominator of the given rational expressions is 2x^3(x + 4). This is the smallest expression that both denominators can be multiplied by to obtain equivalent fractions with a common denominator.

To find the least common denominator (LCD) of the rational expressions 1/(2x^2 + 8x)and 10/x^2, we need to determine the common factors in the denominators and then multiply them.

The first denominator, 2x^2 + 8x, can be factored as 2x(x + 4), where x + 4 is a linear factor.

The second denominator,[tex]x^2[/tex], is already in its factored form.

To find the LCD, we need to consider all the factors and their highest powers. In this case, we have:

2x(x + 4) and [tex]x^2[/tex]

Since the highest power of x in 2x(x + 4) is 1 and in [tex]x^2[/tex] is 2, the LCD must include both factors with their highest powers. Therefore, the LCD is:

LCD = 2x(x + 4)(x^2)

Simplifying further, we can write the LCD as:

LCD = 2x^3(x + 4)

So, the least common denominator of the given rational expressions is 2x^3(x + 4). This is the smallest expression that both denominators can be multiplied by to obtain equivalent fractions with a common denominator.

Using the LCD, we can then add or subtract the rational expressions by multiplying each term by the necessary factors to achieve the common denominator.

Therefore , the solution of the given problem of interest comes out to be $90 is the interest earned by next summer.

Simple interest is calculated by dividing the principal by the borrowing cost, the remaining time, and other elements. The simple return formula in marketing is principal + interest plus hours. Utilizing this method is the simplest way to calculate interest. As a percentage of the principle sum is the most frequent way to calculate income. For instance, he will only pay his portion of the 100% cost if he borrows $100 from a friend and agrees to pay the loan back with 5% interest.. You have to pay interest on money you borrow, and you have to charge interest on money you lend.

Here,

The zero of the polynomial 3x³ 4x² 7 is -7/3.

In order to find the zeros of a polynomial, one must first factor the equation and then set it equal to zero. The zeros of a polynomial are the values of x that make the equation equal to zero. The zeros of a polynomial can be found by factoring the polynomial and then solving for x, which will produce the x values that make the equation equal to zero.

The zero of the polynomial 3x³ 4x² 7 is -7/3. This can be calculated by setting the polynomial equal to 0 and solving for x.

3x³ 4x² 7 = 0

3x³ 4x² = -7

3x(x² - 4) = -7

x(x² - 4) = -7/3

x² - 4 = -7/3

The required equation of line ℓ is y = x + 3.

The slope of the line of reflection is the negative reciprocal of the slope of the line connecting the original point and the image point.

To find the slope of the line connecting A and A', we can use the slope-intercept form of a line:

y = mx + b

where m is the slope and b is the y-intercept.

To find the slope, we can use the difference of y-coordinates over the difference of x-coordinates, or

m = (1-5)/(6-2) = -4/4 = -1

The slope of the line connecting A and A' is -1

Since the line of reflection has a negative reciprocal slope, its slope is 1

Now we can use a point on the line of reflection and the slope to find its equation.

We know that point A(2,5) is on the line of reflection

We can use the point-slope form of a line:

x = 1221/2 (In mixed number form)

Step-by-step explanation:

To find the coordinates of two points given an equation, you can substitute different values of x into the equation and solve for y, or by using the symmetry property of the equation.

The first method to find the coordinates of two points is to  substitute different values of x into the equation and solve for y. Once you have the coordinates of the two points, you can use them to graph the equation and further analyze the function.

For example, if the equation is y = 2x + 1, you can substitute x = 0 and x = 1 into the equation to find the coordinates of the two points. Substituting x = 0 gives y = 2(0) + 1 = 1, so the first point is (0,1). Substituting x = 1 gives y = 2(1) + 1 = 3, so the second point is (1,3).

Another way to find the coordinates of two points is by using the symmetry property of the equation. For example, if the equation is y = -x^2 + 4x -3, you can substitute x = -1 and x = 1 into the equation and solve for y.

In conclusion, finding the coordinates of two points given an equation involves substituting different values of x into the equation and solving for y, or by using the symmetry property of the equation.

When t = π and t = 3π, the acceleration of a particle moving along the x axis with position function x ( t ) = 4 sin ( (π − t) / 2 ) for 0 ≤ t ≤ 4 π where t is measured in seconds is zero.

An acceleration of 0 means that the velocity of the particle is constant, so the derivative of the velocity function is 0. Therefore, the particle has an acceleration of 0 when the second derivative of the position function is 0.

The position function is

x(t) = 4 sin((π − t) / 2)

so the velocity function is

x'(t) = -2cos((π − t) / 2)

and the acceleration function is

x''(t) = - sin((π − t) / 2).

To find when x''(t) = 0, we set -sin((π − t) / 2) = 0 and solve for t:

- sin((π − t) / 2) = 0

sin((π − t) / 2) = 0

(π − t) / 2 = nπ, where n is an integer

t = π - 2nπ

So the particle has an acceleration of 0 when t = π - 2nπ, where n is an integer.
