Prove that P(2,3), (3, 4), R(5, 6) and S(4,5) are the vertices of a rhombus

MatroZZZ [7]

Solution :-

Given coordinates to us are ,

P(2,3) .
Q(3,4).
R(5,6)
S(4,5)

Here it is asked to Prove that these are vertices of Rhombus . So we know that all sides of a Rhombus are equal .So if we show that value of all sides lenght are equal , then it will be a Rhombus .

We will use Distance Formula .

Now , here ,

Distance between P and Q :

⇒ x = √ (2 - 3)² + (3-4)² .

⇒ x = √ (-1)² + (-1)² .

⇒ x = √ 1 + 1 .

⇒ x = √2 .

Distance between Q and S :

⇒ x =√ [ (3-4)² + (5-4)².

⇒x = √ 1² + 1² .

⇒ x = √ 1 + 1 .

⇒ x = √2 .

Similarly we can prove other distances equal.

Please help!!(ﾉ◕ヮ◕)ﾉ*:･ﾟ✧will mark brainliest!!!

Vanyuwa [196]

Step-by-step explanation:

so,

1/12 × $100

5/12 × $20

6/12 × $1

so the expected "payout" is

100/12 + 100/12 + 6/12 = 206/12 = 103/6 ≈ $17.17

minus the $2 entrance fee, the expected value is

17.17 - 2 = $15.17

but of course, there will be 6 losing $1 (while the other 6 will go home with a positive result).
