Is he square root of -144 rational or irrational?
gladu [14]

Answer:

Step-by-step explanation:

Neither.

It is a complex number. The - sign is the culprit. sqrt(-144) = i * sqrt(144) = 12 i

The "i" is an imaginary representation for the square root of -1. It is a definition for sqrt(-1). So a new category of number has been created. The ancients would have been profoundly surprised to learn that such a thing existed.

Calculate the distance between the two given point T(6,-2),U(-2,-12)
slava [35]
Use the distance formula: \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

(6, -2), (-2, -12)
\sqrt{(-2 - 6)^2 + (-12 - -2)^2} ⇒ \sqrt{(-8)^2 + (-10)^2}
\sqrt{64 + 100} ⇒ \sqrt{164}
\sqrt{164} = 12.8

The distance between points T and U is 12.8 units.
