Question

7. Find the distance between points F(7,21) and G (-5, 18) to the nearest tenth.

d = v(x2 – x.) + (y1 - y.)"

Answer 1

`\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ F(\stackrel{x_1}{7}~,~\stackrel{y_1}{21})\qquad G(\stackrel{x_2}{-5}~,~\stackrel{y_2}{18})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ FG=√((-5-7)^2+(18-21)^2)\implies FG=√((-12)^2+(-3)^2) \\\\\\ FG=√(144+9)\implies FG=√(153)\implies \stackrel{\textit{rounded up}}{FG = 12.4}`
