Given that point (-5, -6) is a point on the terminal side of <span>θ. Since both the x coordinate and the y-coordinate are negative, </span><span>θ is in the third quadrant.

The side opposite </span><span>θ is -6 and the side adjacent </span><span>θ is -5.

The hypothenus is given by \sqrt{(-6)^+(-5)^2}=\sqrt{36+25}=\sqrt{61}

The exact value of cos</span><span>θ is given by:

\cos\theta= \frac{adjacent}{hypothenuse} = \frac{-5}{\sqrt{61}}

</span>The exact value of csc<span>θ is given by:

\csc\theta= \frac{hypothenuse}{opposite} = \frac{\sqrt{61}}{-6}</span>

The exact value of tan<span>θ is given by:

\tan\theta= \frac{opposite}{adjacent} = \frac{-6}{-5} =1.2</span>

A scuba diver is diving at a constant rate when her
Helen [10]

Answer:

-0.25 ; 120 seconds 72 seconds

Step-by-step explanation:

Dive rate is constant :

Change in elevation after 8 seconds :

18 feets to 20 feets below

Rate of change = distance / time

(18 - 20) feets / 8 seconds

(-2 / 8) = - 0.25 feets per second

To reach 50.feets :

She needs to cover (50 - 20) = 30 feets

Time = distance / speed ; 30 feets / 0.25 = 120 seconds
