Set Question involving real and natural numbers
Allushta [10]

Only two real numbers satisfy x² = 23, so A is the set {-√23, √23}. B is the set of all non-negative real numbers. Then you can write the intersection in various ways, like

(i) A ∩ B = {√23} = {x ∈ R | x = √23} = {x ∈ R | x² = 23 and x > 0}

√23 is positive and so is already contained in B, so the union with A adds -√23 to the set B. Then

(ii) A U B = {-√23} U B = {x ∈ R | (x² = 23 and x < 0) or x ≥ 0}

A - B is the complement of B in A; that is, all elements of A not belonging to B. This means we remove √23 from A, so that

(iii) A - B = {-√23} = {x ∈ R | x² = 23 and x < 0}

I'm not entirely sure what you mean by "for µ = R" - possibly µ is used to mean "universal set"? If so, then

(iv.a) Aᶜ = {x ∈ R | x² ≠ 23} and Bᶜ = {x ∈ R | x < 0}.

N is a subset of B, so

(iv.b) N - B = N = {1, 2, 3, ...}

Helppppppppppppppppppppp!
Alenkinab [10]

Answer:

±(√35 i)

Step-by-step explanation:

\pm\sqrt{-35}

We need to solve the above equation using the imaginary unit i.

We know i= √-1

Solving

±√-35 =±( √-1 √35)

         = ±(√35 i)Since 35 = 5*7 or 35*1 it cannot be further simplified

So our answer is ±(√35 i).

Round 5,268.9284 to the nearest thousand
svet-max [94.6K]
The answer would be 5 thousand because the decimal doesn't count and you have 268 and that's lower than 500

You live 6 miles from school. if you start walking from school at 3:00, and your best friend starts skateboarding from school to
777dan777 [17]

Answer: 2 hrs 40 min

Step-by-step explanation:  Ok I might be wrong so try to do other people's answers instead of mine.

So your friend is going 6 miles per hour, so he/she will be there in an hour

But you are going 3.5 miles an hour.

So what I did was divide 3.5 by 5 and 60 by 5 and found out that you are going 0.5 miles every 20 min. Then I added up the distance and time and got 6 miles every 2 hrs and 40 min

REMINDER: I might be wrong because I haven't done this question before, but tell me if I'm right or not! :D
