Let A = {1, 2, 3, 4, 5, 6, 7, 8, 9}. n distinct integers will be chosen from A. How big does n have to be

Hitman42 [59]

Partition the set A into 4 subsets: {1, 8}, {2, 7}, {3, 6}, and {4, 5}, each consisting of two integers whose sum is 9. If 5 integers are selected from A, then by the Pigeonhole Principle at least two must be from the same subset. But then the sum of these two integers is 9.

The vertex form of the equation of a parabola is y = 2(x + 4)2 - 21.

Ronch [10]

Answer:

y = 2x^2 + 16x + 11

Step-by-step explanation:

2(x + 4)^2 - 21

2(x + 4)(x + 4) - 21

2(x^2 + 8x + 16) - 21

2x^2 + 16x + 32 - 21

2x^2 + 16x + 11

Find the length of the second leg of the triangle round to the nearest hundredth

horsena [70]

Answer:

$\displaystyle \frac{3\sqrt{230}}{5}$

Step-by-step explanation:

Use the Pythagorean Theorem:

$\displaystyle a^2 + b^2 = c^2 \\ \\ 9,7^2 + b^2 = 13,3^2; \sqrt{82,8} = \sqrt{b^2} \\ \\ \frac{3\sqrt{230}}{5}\:[or\:9,0994505329...] = b$

So, you have this:

$\displaystyle 9,1 ≈ b$

PLEEAASE HELP MEEEEEE

Gre4nikov [31]

$\mathsf{1.\; \frac{x - 6}{2} = x + 13}$

⇒ x - 6 = 2x + 26

⇒ x = -32

⇒ This Equation has One Solution

So, It matches with A in Column B

2. 2 + 6x - 7 = 8 + 2x - 10 + 4x

⇒ 6x - 5 = 6x - 2

As, They are Equations of Parallel Lines. They never meet each other.

⇒ This Equation has No Solution

⇒ So, It matches with B in Column B

3. 15x + 25 = 15x + 10

As, They are Equations of Parallel Lines. They never meet each other.

⇒ This Equation has No Solution

⇒ So, It matches with B in Column B

4. 16 + 8x = 4(2x + 4)

⇒ 16 + 8x = 16 + 8x

As, Both Equations are Same. They Represent the Same Line.

⇒ This Equation has Infinite Number of Solutions

⇒ So, It matches with C in Column B
