2sqrt(74)~~17.22√74≈17.2

Explanation:

d=sqrt((x_1-x_2)^2+(y_1-y_2)^2)d=√(x1−x2)2+(y1−y2)2
d=sqrt(14^2+(-10)^2)d=√142+(−10)2
d=sqrt(296)=2sqrt(74)~~17.2d=√296=2√74≈17.2

sqrt296~~17.2" to 1 dec. place"√296≈17.2 to 1 dec. place

Explanation:

"calculate the distance using the "color(blue)"distance formula"calculate the distance using the distance formula

•color(white)(x)d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)∙xd=√(x2−x1)2+(y2−y1)2

"let "(x_1,y_1)=(88,-8)" and "(x_2,y_2)=(74,2)let (x1,y1)=(88,−8) and (x2,y2)=(74,2)

d=sqrt((74-88)^2+(2+8)^2)d=√(74−88)2+(2+8)2

color(white)(d)=sqrt(196+100)=sqrt296~~17.2d=√196+100=√296≈17.2
