Question

Find the distance between the two points.(-3,2)10,0)✓ [?]Enter the number thatgoes beneath theradical symbolEnter

Answer 1

The distance between two points on a coordinate grid can be calculated as follows;

`\begin{gathered} d^2=(x_2-x_1)^2+(y_2-y_1)^2 \\ \text{The given points are} \\ (-3,2) \\ (0,0) \\ d^2=(0-\lbrack-3\rbrack)^2+(0-2)^2 \\ d^2=(0+3)^2+(-2)^2 \\ d^2=3^2+(-2)^2 \\ d^2=9+4 \\ d^2=13 \\ d=\sqrt[]{13} \end{gathered}`

The number that goes beneath the radical symbol is 13, that means the answer is square root 13.
