fiasKO [112]

Answer:70

Step-by-step explanation:

Given

total of 7 friends need to be divided in two groups with 3 member each and 1 leader

leader can be chosen out of 7 person in $^7C_1$ ways

And 3 person out of remaining 6 persons in $^6C_3$ ways

thus a total of $^7C_1\times ^6C_3$ ways is possible

If order is not matter then

$\frac{140}{2}$ ways are possible

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 $4\sqrt{13}$
