Write an input and output pair that is a function and stays a function when you switch the input and output

strojnjashka [21]

9514 1404 393

Answer:

{(1, 2), (3, 4)}

Step-by-step explanation:

If you want both the relation and its inverse to be functions, there can be no repeated x-values, and no repeated y-values.

In the above pair of points, I have avoided duplicates by making all of the values different. That is not necessary, but it satisfies this problem easily.

Trigonometry

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Identify

Angle θ = ∠R

Opposite Leg of ∠R = 10√3

Hypotenuse = 20

Step 2: Solve

Substitute in variables [sine]: $\displaystyle sin(R^\circ) = \frac{10\sqrt{3}}{20}$
[Equality Property] Trig inverse: $\displaystyle R^\circ = sin^{-1}(\frac{10\sqrt{3}}{20})$
Evaluate trig: $\displaystyle R = 60^\circ$
