Find an equation for the perpendicular bisector of the line segment whose endpoints
zzz [600]

Answer:

y= -7/2x-26/2 or y= -7/2x-13

Explanation:

To solve this question you need all of these formulas:

gradient: \frac{y2-y1}{x2-x1} , Point-Slope y-y1=m(x-x1) ,

perpendicular m (m1)x(m2)=-1 , Midpoint (\frac{x1+x2}{2},\frac{y1+y2}{2} )

and equation of a line y=mx+c

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: m=\frac{-4-(-8)}{5-(-9)} , 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 = \frac{-1}{2/7} = -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) = (\frac{-9+5}{2} ,\frac{8+(-4)}{2} ), 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

To make sure the answer is correct.

Hope it helps :)

Isaac pours water into one container and liquid acetone Into another. He seals both conclusions. He measures the gas pressure ab
MrRissso [65]

Answer:

Water

Explanation:

Acetone has a higher vapour pressure than water because acetone molecules only experience dispersion forces and diploe interactions as the dominant intermolecular forces.

In addition to these mentioned, water molecules are held together by strong hydrogen bonds. Therefore, water has a much lower vapour pressure than acetone and requires greater energy to break these hydrogen bonds and convert the liquid water to gaseous state.

Which explains the seasonal variation in the number of hurricanes that form in the Atlantic?
ASHA 777 [7]
<span>B) Hurricanes derive their energy from heat. 
</span><span>
A hurricane begins with a pre-existing disturbance, an area of low pressure. Favorable conditions advances to the formation of hurricanes. The first one which greatly contributes to the seasonal variation in the number of hurricanes that form in the Atlantic is an increase in sea surface temperatures. For a tropical depression to mature into a hurricane, it requires heat energy from the ocean surface.</span><span>
