Find the distance between (2,4) and (12, 9) on a coordinate plane. round to the nearest tenth if necessary. *
atroni [7]
Use pythagoras

d = √(Δx² + Δy²)
d = √(12-2)² + (9-4)²
d = √(10² + 5²)
d = √(100 + 25)
d = √125
d = 5√5
d = 5 × 2.236
d = 11.18

The nearest tenth is 11.2, so the distance is near to 11.2

Ede4ka [16]
Remember
\frac{x^m}{x^n}=x^{m-n}
and
x^{-m}=\frac{1}{x^m}

so
\frac{3^2}{3^4}=3^{2-4}=3^{-2}=\frac{1}{3^2}=\frac{1}{9}
