Find an equation for the perpendicular bisector of the line segment whose endpoints
are (5, -4) and (-9, -8)
Answers
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 might food supply in Lics (low income countries) be reduced as a result of climate change?
Answers
Answer:
Most of the time LIC's are self-employed (work in agriculture).
Explanation:
Therefor, people who live in LIC's mainly depend on the weather as most people who live in low income countries provide food, via farming. Climate change would cause a result of low food supply due to high levels of heat in the summer which could cause the crops to die due to lack of water; as dry soil conditions would cause reduction in the growth of crops, pasture and vegetation.

What is coastal erosion?The phrase "four new innovations" refers to the "four great inventions" of ancient China, which were the compass, printing, gunpowder, and papermaking. To become what it calls a "innovation nation" by 2020, China has been placing a lot of focus on technology development.
The abacus, the sundial, and the Kongming lantern were among the first creations. By the end of the Middle Ages, 1000 years later, only Europe was aware of the Four Great Inventions—the compass, gunpowder, papermaking, and printing—which were among the most significant technological developments.
Increasing sea levels, storms, and other natural occurrences erode down or wash away the rocks, soil, and sand that make up a shoreline. This process is known as coastal erosion. Tens of thousands of acres of land are lost due to this process every year, and it also results in property damage costing hundreds of millions of dollars.
Thus, option B is correct.

Answers
Answer:
I think it is atmosphere
The atmosphere you are interacting with each of Earth’s spheres. The correct option is A. Understanding the interactions between the earth's spheres and the events that take place within the ecosystem allows people to forecast the outcomes of events.
What does the interaction sphere mean?An event can cause changes in one or more of the spheres, and/or an event can be the result of changes in one or more of Earth's four spheres. An interaction is a two-way cause-and-effect relationship between an event and a sphere. Interactions take place between the spheres as well.
The geosphere's surface, where the rocky part of our planet comes into contact with water, air, and/or life, is where the spheres generally intersect and interact. Sphere interactions are the processes that move matter and energy from one sphere to another.
Thus, the ideal selection is option A.
