They are used to prevent heat loss or protect from heat transfer.

Explanation

P(A) is the power set of A = {1, 2}, which includes all subsets: ∅, {1}, {2}, {1, 2}.

So, {2} is one of the subsets, hence it is an element of P(A).

Explanation

Equal sets have exactly the same elements, regardless of order.

Since A = {a, b, c} and B = {b, c, a} contain the same elements, they are equal.

Explanation

Let's simplify the expression:

√1-sin²θ/sinθ = √(cos²θ)/sinθ (since 1 - sin²θ = cos²θ)

= cosθ/sinθ

= cotθ

Explanation

0 is called additive identity because a + 0 = a for any number 'a'.

It does not change the value of a number when added.

Explanation

To convert (10101)₂ to decimal: = 1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰

= 16 + 0 + 4 + 0 + 1

= 21

Explanation

(n - 2)180° formula calculates the sum of all internal angles of an n-sided polygon.

It works because any polygon can be divided into (n - 2) triangles.
