The points shown on the graph are (-1,2) and (1,-2).
d = sqrt{-2-2)^2 + (1-(-1))^2}
d = sqrt{(-4)^2 + (1+1)^2}
d = sqrt{16 + 4}
d = sqrt{20}
d = 4•sqrt{5}
d is about 8.94427191.
Rounded to the nearest tenth, we get d = 8.9.
"zeros" are solutions for x that make the equation equal to zero.
(x - 8)(x + 8)(x - 1) = 0
What you will have to do is times 46.5 by 100 then with that answer you will divide that by 75 and you will get 62%
