Find an equation for the perpendicular bisector of the line segment whose endpoints
are (5, -4) and (-9, -8)
Answer:
y= -7/2x-26/2 or y= -7/2x-13
Explanation:
To solve this question you need all of these formulas:
gradient: [tex]\frac{y2-y1}{x2-x1}[/tex] , Point-Slope [tex]y-y1=m(x-x1)[/tex] ,
perpendicular m [tex](m1)x(m2)=-1[/tex] , Midpoint [tex](\frac{x1+x2}{2}[/tex],[tex]\frac{y1+y2}{2} )[/tex]
and equation of a line [tex]y=mx+c[/tex]
where m stands for gradient
First things first.
To start you have to know the data of the line that includes the two endpoints, so you calculate its gradient (m) of this line with the gradient fromula: [tex]m=\frac{-4-(-8)}{5-(-9)}[/tex] , which equals 4/14 or 2/7
(It can also be called rise/run) (Remember the rule of signs where - and - equal +)
with that information you can proceed with the point-slope or point-gradient formula, so you plug the values: y-(-8) = 2/7 (x-(-9)), which results in y+8=2/7(x+9) and then y+8=2/7x+18/7.
To finish the equation you move eight to the other side. To simplify things you can change it into a fraction as I did, and remember to change signs.
y=2/7x+18/7 -8 -> y=2/7x+18/7-56/7 . This gives us the number of y=2/7x-38/7, which is the equation of the first line.
Now to know the gradient of the second line you apply the formula of perpendicular bisector where m1 x m2 = -1. We know m1 (gradient of the first line) is 2/7, so m2 = [tex]\frac{-1}{2/7}[/tex] = -7/2. m2 is therefore -7/2
Now you have to know the midpoint between the two endpoints, which will act as the start point of the perpendicular bisector
M (midpoint) = [tex](\frac{-9+5}{2} ,[/tex][tex]\frac{8+(-4)}{2} )[/tex], which give us the coordinates of (-2, -6)
(remember, x coordinate is always first)
with this point we can apply again the point-slope formula to know the equation of the line:
y-(-6)=-7/2(x-(-2)) -> y+6=-7/2(x+2) -> y+6=-7/2x - 14/2
Move the 6 to isolate the y
y=-7/2x -14/2 - 12/2
which equals y= -7/2x -26/2

Which weather pattern consists of a high-pressure system with descending cool, dry air that leads to clear weather? O The Coriolis effect O Convection currents O Cyclone movement O Anti-cyclone movement
Answer:
D. Anti-cyclone movement.
Explanation:
Cyclone movement has winds that circulate at a low pressure, and the opposite of the would be anti-cyclone movement, which is the high pressure winds that circulate clockwise.
Answer: Anti-Cyclone Movement
Explanation: That’s the definition

What is Ancient?Ancient history spans the era from the start of writing and the beginning of human history as we know it up until late antiquity. The Sumerian cuneiform script marks the beginning of the nearly 5,000-year history of writing. All of the continents that humanity inhabited between 3000 BCE and 500 CE are included in ancient history.
Helots, or state-owned slaves, existed in Sparta. Slaves' lives in Athens were a little bit better. In Athens, slaves were privately owned, and a ceremony was held to welcome a new slave into the family. In Athens, slaves frequently collaborated with free people, albeit they were not paid.
