yes, to complete her goal she would need to run roughly 14.3 so this is more than enough
F(x)=2x²+5√(x-2)
f(3)=2(3)²+5√(3-2)
= 2 (9) + 5√1
= 18 + 5
= 23.
Pythagorean Theorem: a^2 + b^2 = c^2
(5)^2 + (9)^2 = c^2
25 + 81 = c^2
106 = c^2
c = square root of 106
Length of a diagonal of a rectangle is square root of 106.
