Use the distance formula to find the distance between the points given.

masha68 [24]

The distance between the points is $4\sqrt{13}$

Step-by-step explanation:

The formula of the distance between two points $(x_{1},y_{1})$ and

$(x_{2},y_{2})$ is $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

To find the distance between two point:

Put one of the two point as $(x_{1},y_{1})$
Put the other point as $(x_{2},y_{2})$
Substitute then in the rule of the distance and calculate the distance

∵ The two points are (18 , -2) and (6 , -10)

- Put (18 , -2) as $(x_{1},y_{1})$ and (6 , -10) as $(x_{2},y_{2})$

∴ $x_{1}$ = 18 and $x_{2}$ = 6

∴ $y_{1}$ = -2 and $y_{2}$ = -10

- Substitute them in the rule below

∵ $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

∴ $d=\sqrt{(6-18)^{2}+(-10--2)^{2}}$

∴ $d=\sqrt{(-12)^{2}+(-10+2)^{2}}$

∴ $d=\sqrt{(-12)^{2}+(-8)^{2}}$

∵ (-12)² = 144 and (-8)² = 64

∴ $d=\sqrt{144+64}$

∴ $d=\sqrt{208}$

∵ $\sqrt{208}=4\sqrt{13}$

∴ $d=4\sqrt{13}$

The distance between the points is $4\sqrt{13}$

Two towns that are 31.5 km apart are 3 cm apart on a map. What is the scale of the map?

3241004551 [841]

Answer:

2 cm = 21 km

Step-by-step explanation:

2 cm = 21 km

This is why

3cm = 31.5 km

3/3 = 31.5/3 (To find out how much 1 cm is equal to)

1 cm = 10.5 km

And since 1 cm = 10.5 km is not there in the options... I tried to find out for 2 cm

So, I multiplied both sides by 2

1 cm = 10.5 km

1 *2 = 10.5 *2

So the answer become 2 cm = 21 km
