Explanation:
#"using the 3-d version of the "color(blue)"distance formula"#
#•color(white)(x)d=sqrt((x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2)#
#"let "(x_1,y_1,z_1)=(-1,4,-4)#
#"and "(x_2,y_2,z_2)=(13,15,-2)#
#d=sqrt((13+1)^2+(15-4)^2+(-2+4)^2)#
#color(white)(d)=sqrt(196+121+4)#
#color(white)(d)=sqrt321~~17.92" to 2 dec. places"#
