Answer:

11.31 units

Step-by-step explanation:

a^2 + b^2 = c^2

8^2 + 8^2 = c^2

64 + 64 = c^2

128 = c^2

Opposite of exponents is square roots, and we need to get rid of that exponent in c^2, meaning we find the square root.

\sqrt{128\\} \\\\ = c

c = 11.31 units

f(x) = -x² + 10x - 6

f(-5) is x = -5

<u>Step 2: Evaluate</u>

  1. Substitute:                    f(-5) = -(-5)² + 10(-5) - 6
  2. Exponents:                   f(-5) = -(25) + 10(-5) - 6
  3. Multiply:                        f(-5) = -25 - 50 - 6
  4. Subtract:                       f(-5) = -75 - 6
  5. Subtract:                       f(-5) = -81
