What are 2 fine arts in southern Mexico? Thank you in advance. I need this answer today if you can.

3. If you see a flash of lightning and hear thunder 8 seconds later, how far is the lightning from you? 4. Why is lightning most

Vlad1618 [11]

Answer:

2.656 km

Explanation:

Velocity of sound in the air = 332 m/s

time t= 8 sec

$distance = velocity\times time$

$distance= 332\times8$

=2656 meters =2.656 km

therefore, distance = 2.656 km

Florida has lightening quite often because

Florida receives a lot of heat through out the year, air close the ground is warmed and frequent sea breezes (Florida is surrounded by seas and oceans) provide the necessary lift and moisture for the formation of thunderstorms. This why lightning is common Florida

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.

QUESTION 32 A quasi-experimental study is one in which: 1. Participants are randomly assigned to intervention or control 2. Ther

love history [14]

Answer:

1. Participants are randomly assigned to intervention or control

Explanation:

Quasi-experimental study -

It is the study to estimate the impact of an intervention on the target population with any random assignment .

This Quasi-experimental research shares , the similarities with the randomized controlled trial or the traditional experimental design .

But in this study , there is random assignment for the control or treatment .

Hence , from the options given in the question , the correct is ( 1 ) .
