Answer:

tan(θ) = 0, 0.577, -0.577

Step-by-step explanation:

3tan³(θ) - tan(θ) = 0

tan(θ) = 0

tan²(θ) = ⅓ tan(θ) = +/- sqrt(⅓)

tan(θ) = 0, sqrt(⅓), -sqrt(⅓)

tan(θ) = 0, 0.577, -0.577

Tema [17]

9514 1404 393

Answer:

  yes

Step-by-step explanation:

1. The total length David needs is (1.75 m) × 4 = 7.00 m. His 7.28 m piece is long enough to provide the pieces he needs.

__

2. The length of each piece when the wood is cut into quarters is ...

  (7.28 m)/4 = 1.82 m

This is longer than the 1.75 m needed, so each piece is long enough.
