There are 6 days remaining until May 3, 2018.
The distance between two points knowing theirs coordinates:
AB =√[(x₂-x₁)² +(y₂-y₁)²]; ===>A(-2,4) & B(0,-6) Given
A(x₁,y₁) & B(y₂,y₁)
AB =√[(0-(-2))²+(-6-4)²] =√(104) = 10.198 ≈ 10.2
Haven't you tried to answer these yourself?
Let me give you 2 examples:
First: The product of sqrt(2) and sqrt(25) is 5sqrt(2), which is irrational because sqrt(2) is irrational.
Second: 2pi*r evaluated at pi^(-1) is rational because pi/pi = 1 and 2 itself is rational.
A = -2 if you do it all right
