Answer:

{π/4, 5π/4}

Step-by-step explanation:

Tan theta -1=0 could be rewritten as tan Ф = 1. The tangent function is 1 at Ф = π/4. As the period of the tangent function is π,

tan Ф = 1 will be true for Ф = π/4 + π, or (5/4)π.

The solution set is {π/4, 5π/4}.

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is $1308-48=1260\ \text{m}$

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

$\dfrac{1263}{35}=36\ \text{minutes}$

The time taken by the submersible to dive the required distance is 36 minutes.
