Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the longer term.

Time is a quantity that is a part of several measurements that are used to compare the length of events or the gaps between them,  to match how long they last, to order events, and to live how quickly things change in the real world or in our conscious experience.  together with the three spatial dimensions, time is usually referred to as a fourth dimension.

Time has long been an important topic of study in philosophy, theology, and science, but scholars haven't been able to define it in a way that is applicable to all of these disciplines without becoming circular. Nevertheless, numerous industries and business domains.

Step-by-step explanation:

-7 + -1 + -4 + 0 + 2 = -10

-10 / 5 = -2

Answer:

w = -2, (-1/5)

Step-by-step explanation:

2|4w - 1| = 3|4w + 2|

8w - 2 = 12w + 6

-12w      -12w

-------------------------

-4w - 2 = 6

      +2   +2

---------------------

-4w = 8

÷-4    ÷-4

w = -2

2|4(-2) - 1| = 3|4(-2) + 2|

2|-8 - 1| = 3|-8 + 2|

2|-9| = 3|-6|

18 = 18

----------------------------------------------------------------------------------------------------------

2|4w - 1| = -(3|4w + 2|)

2|4w - 1| = -3|4w + 2|

8w - 2 = -12w - 6

+12w      +12w

-------------------------

20w - 2 = -6

        +2   +2

20w = -4

÷20    ÷20

------------------

w =(-1/5)

2|4(-1/5) - 1| = 3|4(-1/5) + 2|

2|(-4/5) - 1| = 3|(-4/5) + 2|

2|(-9/5)| = 3|(6/5)|

Answer:

Step-by-step explanation:

Construct the centroid (medians), circumcenter (perpendicular bisectors), and orthocenter of a right triangle (altitudes).

The three angle bisectors of a triangle are concurrent in a point equidistant from its sides. The incenter of a triangle is the point at which the triangle's angle bisectors intersect. The incenter is always inside the triangle.

The point where the three perpendicular bisectors meet is the circumcenter of a triangle. It is the circumcenter of the circle encircling the triangle, equidistant from the triangle's three vertices.

The incenter exists crucial for angle bisectors; the orthocenter is important for perpendicular bisectors; the circumcenter is important for altitudes; and the centroid is important for medians.

The slope of the line passing through two points (-1, 6) and (3, -4) is Option A ( m = [tex]\frac{-5}{2}[/tex] )

It is given that, the line is passing through two points (-1, 6) and (3, -4)

Slope is the measurement of the level of steepness of the line or it is a line's steepness determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

The formula to find the slope of the line passing through two points is given by

m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

We need to find the slope of the line passing through both points

where y1 = 6, y2 = -4, x1 = -1, x2 = 3

Putting values in the formula to find the slope of the line

we get,

m = [tex]\frac{-4 - 6}{[3 -(-1)]}[/tex]

m = [tex]\frac{-10}{4}[/tex]

m = [tex]\frac{-5}{2}[/tex]

Hence The slope of the line passing through two points (-1, 6) and (3, -4) is m = [tex]\frac{-5}{2}[/tex]

Extend the triangle's size by -1/3 with the center point (-1,2).

The triangle's vertices of new location point are (-2,1),(0,1) and (-3,4).

The triangle's vertices' coordinates are not specified. Assume that the triangle's vertices are located at points A(2, 5), B(-4, 5) and C. (5, -4).

A point is transformed when it is moved from its original location to a new one. Reflection, rotation, translation, and dilation are examples of Dilation is the growth or contraction of an object's size. A point A(x, y) is displaced from a point (a, b) by a factor k as follows:

The distance between the midpoints of segments OA and OB is 1.5 cm.

Given that, points O, A, and B lie on the same line. OA = 12 cm, OB = 9 cm.

We need to find the distance between the midpoints of segments OA and OB.

A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments. The midpoint of a line segment is the point on a segment that is at the same distance or halfway between the two ending points.

Let X be the midpoint of OA and Y be the midpoint of OB.

Now, the midpoint of OA is OX=AX=OA/2

=12/2=6 cm

Then, the midpoint of OB is OY=YB=OB/2

=9/2=4.5 cm

The distance = 6-4.5=1.5 cm

Therefore, the distance between the midpoints of segments OA and OB is 1.5 cm.

Functions can be reflected on the x-axis, the y-axis, or both axes. For example, function reflection y= f(x) can be written as y= -f(x) or y= f(-x) even y= -f(-x). There are four types of function or graph transformations: reflection, rotation, translation, and dilation. In mathematics, especially geometry, mirror or mirroring means flipping, so basically, the mirroring of a function is the mirror image of a given function or graph. Hence the reflection function is commonly known as the reflection function.

The reflection of the given function should be similar in size and shape to the original function.

A pair of opposite angles is supplementary, a quadrilateral ABCD can be inscribed in a circle.

Every circle has an inscribed triangle with any three given angle measurements (summing to 180°, of course), and every triangle can be inscribed in any circle (which is called its circumscribed circle or circumcircle). Every triangle has an incircle, which is a circle that has been inscribed.

A cyclic quadrilateral is one that can be encircled by a circle. If and only if a pair of opposite angles is supplementary, a quadrilateral ABCD can be inscribed in a circle.

An athlete preparing for a marathon runs 21.3 miles then the athlete will run 34.27903 kilometer.

The kilometer (spelled kilometer in American English) is just a metric unit of length equivalent to one thousand meters.

Since there are 1.6 kilometers in a mile, multiply the number of miles by 1.6 to convert them to kilometers. Because 20 × 1.6 = 32 kilometers, 20 miles is equivalent to 32 kilometers. The more precise method would yield a conversion of 20 miles to kilometers of 32.1868.

Conversion of mile into kilometer.

It is known that, 1 mile = 1.60 kilometer.

Then, 21.3 mile = 1.60 × 21.3 = 34.08 kilometer.

An athlete training for a marathon will cover 34.27903 kilometers if they run 21.3 miles.

Therefore, the athlete will run 34.27903 kilometer.
