A chord is any circle segment that connects two points. A circle chord is always used as the diameter. The chords AE and DE do not intersect in the center. As a result, they are not diameters.

In geometry, a circle's diameter is any straight line segment that passes through the center of the circle and has endpoints on the circle. It is also referred to as the circle's longest chord. Both definitions apply to a sphere's diameter.

The chord of a circle is defined as the line segment connecting any two points on its circumference. It should be noted that the diameter of a circle is the longest chord passing through its center.

A circle chord is a straight line with both ends on a circular arc. A secant line, or simply secant, is the infinite line extension of a chord. A chord is a segment of a line that connects two points on a curve, such as an ellipse.

Since angle ABC (m∠ABC) is bisected by line BD, the measure of m∠DBC is equal to 44°.

A line segment can be defined as the part of a line in a geometric figure such as a triangle, quadrilateral, rhombus, parallelogram, circle, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

A perpendicular bisector can be defined as a type of line that bisects (divides) a line segment exactly into two (2) halves and forms an angle of 90 degrees at the point of intersection.

Since angle ABC is bisected by line BD, we have:

m∠ABD = m∠DBC = m∠ABC/2

m∠ABC/2 = 8x/2 = 4x

Substituting the given parameters into the expression, we have;

m∠ABD = m∠DBC = 4x

2x + 22 = 4x

4x - 2x = 22

2x = 22

x = 22/2

x = 11

Now, we can find m∠DBC as follows:

m∠DBC = 4x

m∠DBC = 4 × 11

m∠DBC = 44°.

Step-by-step explanation:

F=ma

m=310g=0.31kg

a=5m/s^-2.

F=0.31×5

F=1.55N

The value of k is 5/9(F-32) + 273.15.

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other.

Given:

F=9/5(k-273.15)+32

On solving for k

F-32 = 9/5 (k-273.15)

(F-32)*5/9 = (k-273.15)

5/9(F-32) + 273.15 = k

k=5/9F - 290.927

Hence, the value of k is 5/9F - 290.927.

Explicit expressions help represent all members of a sequence in one expression. The explicit formula for an arithmetic sequence is an = a + (n - 1)d, and each term in the sequence can be computed without knowing the other terms in the sequence.

In general, an explicit formula is the nth term of arithmetic, geometric, or harmonic sequence.

Explicit expressions are always used to represent any term in a sequence without describing any other term in the sequence. The meaning of "explicit" is direct, which can be found directly without knowing the other terms in the sequence.

The first and second vehicle form ΔAOC and ΔBOC are congruent so they will be an isosceles triangle.

A graph is a visual representation of how one variable changes over time in connection to one or more other variables.

We must determine the values of y that correlate to the value of x in order to plot the graph.

The coordinate geometry must then be changed to reflect the values of x and y.

Given the condition making a graph as shown below,

Now in ΔAOC and ΔBOC, the angle x is the same.

Distance AO = BO and CO is common side.

So both triangles will be congruent.

All congruent triangles will be isosceles triangles since all sides are equal which means two sides will be equal.

Hence "The first and second vehicle form ΔAOC and ΔBOC are congruent so they will be an isosceles triangle.".

Answer:

see explanation

Step-by-step explanation:

(8x - 75) and (5x) are vertically opposite angles and are congruent , then

8x - 75 = 5x ( subtract 5x from both sides )

3x - 75 = 0 ( add 75 to both sides )

3x = 75 ( divide both sides by 3 )

x = 25

Then

5x = 5(25) = 125°

8x - 75 = 8(25) - 75 = 200 - 75 = 125°

Answer: (5x)°=(8x-75)°=125°

Step-by-step explanation:

Property of vertical angles: vertical angles are equal

Hence,

[tex](8x-75)^0=(5x)^0\\(8x)^0-75^0=(5x)^0\\(8x)^0-75^0-(5x)^0=(5x)^0-(5x)^0\\(3x)^0-75^0=0\\(3x)^0-75^0+75^0=0+75^0\\(3x)^0=75^0\\[/tex]

Divide both parts of the equation by 3 :

[tex]x^0=25^0\\(5x)^0=(5*25)^0\\(5x)^0=125^0[/tex]

We need to find its slant asymptote. The slant asymptote is determined by checking [tex]\lim_{x \to \infty}( g(x)-(ax+b)) = 0[/tex] .

So we first divide the polynomial [tex]3x^2+5x+6[/tex] by x+3 to find such an (ax+b).

        3x - 4  

x+3 | [tex]3x^2+5x+6[/tex]

⇒  [tex]\frac{3x^2+5x+6}{x+3}[/tex] - 3x - 4 =  [tex]\frac{18}{x+3}[/tex]

⇒ [tex]\lim_{x \to \infty}(\frac{3x^2+5x+6}{x+3}-(3x-4)) = 0[/tex]  , since [tex]\frac{18}{x+3}[/tex] [tex]\rightarrow \infty[/tex] as [tex]x \rightarrow \infty[/tex].

One side of the garage length​ is 16.69ft

the length of one side of the garage​ now has 18 ft

increase in the one​ side's length is 70 %

According to the given data,

Floor of square garage given in the question is 216 ft

then, we get length of one side of the garage is √216

                                                                                   = 16.69 ft

after built an addition to it  garage has ​ 50% more floor space

216 × (1 + 0.5) = 324

√324 = 18 ft

The garage's one side is 18 feet long.

The length of one​ side = [tex]\frac{18}{16.69}[/tex]

                                        = 1.07

The percentage increase in one side's length is 1.07-1 = 0.07 = 70 percent.

Area of square : The area is the space covered by square object. It is the approximately occupied by any shape. While estimating the area of a square, we consider only the length of the square because all the sides of a square are equal.

Similarly, we get the area of the other shapes such as rectangle, triangle or any polygon shape, based on its sides. Area of the surface is compute based on the radius or the distance of its outer line from the axis for curved surface objects.

Area of a Square Formula

area of square formula used for calculating the area occupied, let us we find area. You are required to calculate the area of a side 5 cm. Using this dimension,  a square  having 1 cm × 1 cm squares. The square covers 36 complete squares.

Thus, the area of the square is 36 square cm, which can be written as 6cm × 6 cm, that is, side ×  side.

We know the area of a square is:

Area of a Square = Side ×  Side

and the perimeter of any square = 4 ×  side units

Here given, Some conversions of units:
