Midpoint of a segment whose endpoints are (x₁,y₁) and (x₂,y₂)
M((x₁+x₂)/2  ,  (y₁+y₂)/2)
1)
(3,7)
(7,3)

M( (3+7) /2  ,  (7+3)/2 )
M(10/2 , 10/2)
M(5,5)

B(5,5).

2)
Distance between the points (x₁,y₁) and (x₂,y₂)

Distance=√[(x₂-x₁)²+(y₂-y₁)₂]
(6,32)
(-8,-16)
distance=√[(-8-6)²+(-16-32)²]
d=√[(-14)²+(-48)²]
d=√(196+2304)
d=√2500
d=50

D. 50

(2,3)
(7,4)
d=√[(7-2)²+(4-3)²]
d=√(5²+1²)
d=√(25+1)
d=√26≈5.1

d≈5.1

The shaded sector above covers 1/3 of the circle. If the radius of the circle above is 3 cm, what is the area of the sector in t
Mekhanik [1.2K]

Given:

The shaded sector above covers \dfrac{1}{3} of the circle.

Radius of the circle = 3 cm

To find:

The area of the sector in terms of π.

Solution:

The area of a circle is

A=\pi r^2

Substituting r=3, we get

A=\pi (3)^2

A=9\pi

It is given that the shaded sector above covers \dfrac{1}{3} of the circle.

The area of shaded sector =\dfrac{1}{3}A

                                             =\dfrac{1}{3}(9\pi)

                                             =3\pi

Therefore, the area of shaded sector is 3π sq. cm.

There are 20 players on a soccer team. From them, a captain and an alternate captain have to be chosen. How many possibilities a
tester [92]

Answer:

190 possibilities.

Step-by-step explanation:

The problem is called 20 choose 2, given by the formula for combinations

C(20,2) = 20! / (2! (20-2)!) = 190

alternatively, we can reason it this way:

there are 20 choices to choose a captain and 19 choices for an alternate captain for a total of 380 ways.

However, there are 20 choices to choose an alternate captain and 19 choices for a captain for a total of 380 ways.

Since we are essentially double counting every choice of the posts, we need to divide 380 by 2 to get 190 ways.
