Answer:

<h2><em><u>ᎪꪀsωꫀᏒ </u></em></h2>

➪The hour is divided into 60 minutes and the minute into 60 seconds is given by <em><u>Babylonians </u></em> who used a sexagesimal (counting in 60s) system for mathematics and astronomy.

➪They derived their number system from the Sumerians who were using it as early as 3500 BC.

Step-by-step explanation:

hope it's helpful to you !!

This is an example of a piecewise defined function. It means that the function has not a unique formula to represent it, but it depends on "where" you want to compute it.

So, if you choose any input $x$ , you have two alternative:

If $x \neq 3$ (i.e., if you've chosen any input that is not 3), the output will be the opposite of the input you've chosen ( $y=-x$ )
If $x=3$ , the ouput will be -1.

So, let's forget about $x=3$ for a moment. For any input $x$ you choose, the answer is $-x$ . The graph of this function is the bisector of the second and fourth quadrant.

Now remember that there is our special case: you have to "carve a hole" in our line, at $x=3$ , and assing to this point the value -1, instead of what we would expect, i.e. -3.

So, the graph of this function is the line $y=-x$ , except for one point ( $x=3$ ), where we reassign the value to be -1.

mart [117]

Answer:

The ratio of number of woman to the total number is 19 : 24.

Step-by-step explanation:

Total number of members in the club = 24

Number of men = 5

Number of women = 24 - 5 = 19

The ratio of number of women to the total number of members is

= $\frac{19}{24}$

What are the coordinates of the endpoints of the midsegment for △XYZ that is parallel to XZ⎯⎯⎯⎯⎯ ?

Ksenya-84 [330]

The coordinates of the endpoints of the mid-segment of Δ XYZ that parallel to XZ are (1 , 6) and (1 , 3)

Step-by-step explanation:

In a triangle the segment which joining the mid points of two sides:

Parallel to the 3rd side
Its length is equal half the length of the 3rd side
It's called the mid-segment of the triangle

In Δ XYZ

∵ Vertex X is (0 , 7)

∵ Vertex Y is (2 , 5)

∵ Vertex Z is (0 , 1)

∵ The mid-segment of Δ XYZ is parallel to XZ

- The mid-segment intersects the other two sides of the Δ

at their mid-points

∴ The mid-segment intersects XY and YZ at their midpoints

∴ The endpoints of the mid-segment are the midpoints of

XY and YZ

The mid point of a segments whose endpoints are $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is $(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$

∵ X = (0 , 7) and Y = (2 , 5)

∴ $x_{1}$ = 0 and $x_{2}$ = 2

∴ $y_{1}$ = 7 and $y_{2}$ = 5

∵ The mid point of XY = $(\frac{0+2}{2},\frac{7+5}{2})$

∴ The mid point of XY = $(\frac{2}{2},\frac{12}{2})$

∴ The mid point of XY = (1 , 6)

∵ Z = (0 , 1) and Y = (2 , 5)

∴ $x_{1}$ = 0 and $x_{2}$ = 2

∴ $y_{1}$ = 1 and $y_{2}$ = 5

∵ The mid point of ZY = $(\frac{0+2}{2},\frac{1+5}{2})$

∴ The mid point of ZY = $(\frac{2}{2},\frac{6}{2})$

∴ The mid point of ZY = (1 , 3)

∵ The endpoints of the mid-segment are the midpoints of

XY and YZ

∴ The end points of the mid segments are (1 , 6) and (1 , 3)

The coordinates of the endpoints of the mid-segment of Δ XYZ that parallel to XZ are (1 , 6) and (1 , 3)
