Answer:
f(- 2) = 8
Step-by-step explanation:
Evaluating for x = - 2
f(- 2) = 2
- 4(- 2)³ - 11(- 2)² + 3(- 2) - 6
= (2 × 16) + (- 4 × - 8) + (- 11 × 4) - 6 - 6
= 32 + 32 - 44 - 6 - 6 = 8

Answer:
s = 19.0
Step-by-step explanation:
To find s, use the Pythagorean Theorem.
a² + b² = c²
9² + b² = 21²
81 + b² = 441
b² = 360
b = √360
b = 18.97366596 ⇒ 19.0 (rounded to the nearest tenth)
So, s = 19.0.
