What is the distance between (2, -2) and (-8, -2)?

Answers

Given:

(2, -2)(-8, -2)

To find: The distance between the two points.

Answer:

Formula to find the distance:

[tex]\sf Distance\ =\ \sqrt{\Bigg(x_2\ -\ x_1\Bigg)^2\ +\ \Bigg(y_2\ -\ y_1\Bigg)^2}[/tex]

From the given data, we have:

x₁ = 2x₂ = -2y₁ = -8y₂ = -2

Using them in the formula,

[tex]\sf Distance\ =\ \sqrt{\Bigg(-8\ -\ 2\Bigg)^2\ +\ \Bigg(-2\ -\ (-2)\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{\Bigg(-10\Bigg)^2\ +\ \Bigg(-2\ +\ 2\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{100}\ =\ \bf 10\ units.[/tex]

Therefore, the distance between (2, -2) and (-8, -2) is 10 units.

given a set of integers, does any non-empty subset of them add up to zero? That is a decision problem and happens to be NP-complete?

Answers

no because the subset sum problem is a decision problem in computer science. In its most general formulation, there is a multiset S of integers and a target sum T, and the question is to decide whether any subset of the integers sum to precisely. the problem is known to be NP-complete. moreover, some restricted variants of it are NP-complete too, for example.

Answer:

8^18.

Step-by-step explanation:

The Law of exponents.

(x^a)^b) = x^(ab)

Why this happens?

(8^6)^3

Imagine you have 8^6.

8*8*8*8*8*8 to the power of three or ^3.

(8*8*8*8*8*8)^3.

8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8 which = 8^18.

This is why (8^6)^3=(8^(6*3) or 8^18.
