What is the distance of segment bf round to the nearest hundredth.

Step-by-step explanation:

ΔBCE:

Use the Pythagorean theorem:

We have EC = 4cm and BC = 3cm. Substitute:

BF is the diagonal of the square FEBA. The formula of a diagonal of a square with side a is:

Therefore

Approximation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
