In mathematics, a group is an algebraic structure consisting of a set of elements equipped with an operation that combines any two elements to form a third element. The operation satisfies four conditions called the group axioms, namely closure, associativity, identity and invertibility. One of the most familiar examples of a group is the set of integers together with the addition operation, but the abstract formalization of the group axioms, detached as it is from the concrete nature of any particular group and its operation, applies much more widely. It allows entities with highly diverse mathematical origins in abstract algebra and beyond to be handled in a flexible way while retaining their essential structural aspects. The ubiquity of groups in numerous areas within and outside mathematics makes them a central organizing principle of contemporary mathematics.[1][2] Groups share a fundamental kinship with the notion of symmetry. For example, a symmetry group encodes symmetry features of a geometrical object: the group consists of the set of transformations that leave the object unchanged and the operation of combining two such transformations by performing one after the other. Lie groups are the symmetry groups used in the Standard Model of particle physics; Poincaré groups, which are also Lie groups, can express the physical symmetry underlying special relativity; and point groups are used to help understand symmetry phenomena in molecular chemistry.

If you travel 720 miles in 12 hours, which of the following is the amount of time it would take you to travel 360 miles?
Vikki [24]

Answer:

6 Hours

Step-by-step explanation:

360 is half of 720, so it would take half the time to travel. half of 12 is 6

99 POINTS!!! JUST ANSWER THIS QUESTION, PLEASE!!!
-Dominant- [34]

Hi!

I would approach this question by first looking at where the parallelogram is located, by graphing the image. I did so and drew a rough image on Paint (See attached image)

To get the part where the diagonals intersect, I would find the midpoint of the line between points (1, 3) and (5,-9) (or the other pair). The reason is a parallelogram's diagonals always bisect each other, meaning the point they intersect is always the middle of the two diagonals.

Therefore, you can find the midpoint of a diagonal, between (1, 3) and (5, -9). The midpoint theorem is (\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2}.

Take the points (1, 3) and (5, -9), and fill them in.

(\frac{1 + 5}{2} , \frac{3 - 9}{2})

Then solve.

(\frac{6}{2}, \frac{-6}{2})

(3, -3)

If you'd like to check the other midpoint:

Take the points, (8, 3) and (-2, -9)

(\frac{8 - 2}{2}, \frac{3 - 9}{2})

Then solve.

(\frac{6}{2} , \frac{-6}{2})

(3, -3)

They're the same, so that answer is correct.

Hope this helps!
