a scientist graphed the locations of the epicenter of an earthquake and all the places where the people reported feeling the earthquake. She positioned the epicenter at (1,8) and the farthest location reported to have felt the quake was positioned at (85,8). If each unit on the graph represents 1 mile, how far from its epicenter was the earthquake felt?

Answer 1

per the usual distance formula, that would be
√((85-1)^2 + (8-8)^2) = 84

or, you could have just noticed that both points lie on the line
y=8, and are 84 units apart

Answer 2

i will help you so don't worry

Answer 3

the answer is 86
