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

why does a temperate zone support many varieties of organisms
Answer:
Torrid zone is too hot which sometimes causes more hotness in soil and won't have water which helps the plants and organisms not to survive. => In such cases Temperate zone experience both climatic conditions for short periods of time, Hence it supports many varieties of organisms

2.- Es importante conocer otras culturas y porque?
3.- conoces a otras culturas y cuales conoces y si no es así, identifica mínimo 5 culturas mexicanas y descríbelas brevemente.
Los Tarahumaras son un pueblo aborigen nativo de México. Hoy en día hay alrededor de 50.000 de ellos, principalmente en la región de Chihuahua.
La propia cultura de los Tarahumaras se ha conservado bien y es especialmente conocida por su tradición de correr. Su religión mezcla la influencia de sus propias tradiciones y el cristianismo. Se utiliza ropa occidental tradicional y moderna.
El problema de los tarahumaras hoy en día es la falta de educación y servicios de salud. Muchos se quedan sin educación, y los analfabetos representan más de la mitad del total de la población.
