According to the rational root theorem, the following are potential roots of f(x) = 60x2 – 57x – 18
-6/5, -1/4, 3, 6
which is an actual root of f(x)?

-6/5
-1/4
3
6

We have been given the function

Now, the given potential roots are -6/5, -1/4, 3, 6. In order to find the actual root of this function, we substitute the root in the given function and if we get zero, then that would be the actual zero.

We got zero for the value -1/4.

Hence, the actual root of f(x) is -1/4.

B is the correct option.

because they could drop even lower..

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
