Find the distance of the line segment joining the two points (-4 /2 - /12) and (/32, 2/3)

astraxan [27]

Answer: $4\sqrt{3}$ .

Step-by-step explanation:

Distance formula : Distance between points (a,b) and (c,d) is given by :-

$D=\sqrt{(d-b)^2+(b-a)^2}$

Distance between points $(-4\sqrt{2},\sqrt{12}) \text{ and }(-\sqrt{32}, 2\sqrt{3})$ .

$D=\sqrt{(2\sqrt{3}-(-\sqrt{12}))^2+(-\sqrt{32}-(-4\sqrt{2}))}\\\\=\sqrt{(2\sqrt{3}+\sqrt{2\times2\times3})^2+(-\sqrt{4\times4\times2}+4\sqrt{2})^2}\\\\=\sqrt{(2\sqrt{3}-\sqrt{2^2\times3})^2+(-\sqrt{4^2\times2}+4\sqrt{2})^2}\\\\=\sqrt{(2\sqrt{3}+2\sqrt{3})^2+(-4\sqrt{2}+4\sqrt{2})^2}\\\\=\sqrt{(4\sqrt{3})^2+0}\\\\=4\sqrt{3}\text{ units}$

Hence, the correct option is $4\sqrt{3}$ .

Help pleaseeeeeeeeeeee

ollegr [7]

Answer:

Step-by-step explanation:

The temperature at a given altitude is

y = 36 - 3x

The temperature on the surface of the planet is the point (0,t) where t is the temperature for the given height.

y = 36 - 3*0

y = 36

So at the surface of the planet is 36 degrees C.

======================

Effectively it is the slope of the equation which is - 3

So ever km going up will mean a loss of 3 degrees. I think they want you to write -3

What’s the correct name for that line?

GM, because when naming a line, you go from left to right just like how we read.
