Use the given point on the terminal side of angle θ to find the value of the trigonometric function indicated.
Fofino [41]

Answer:  19)  117°                    20) 53°

               21)  229°                   22) 119°

               23) 155°                    24) 323°

<u>Step-by-step explanation:</u>

Use Pythagorean Theorem to find r:     x² + y² = r²

19) x = -\sqrt{17} ,  y = 8,    r = 9

     \cos \theta=\dfrac{x}{r} \rightarrow \quad \cos \theta =\dfrac{-\sqrt{17}}{9} \rightarrow \quad \theta = cos^{-1}\bigg(\dfrac{-\sqrt{17}}{9}\bigg)\rightarrow \quad \theta = \large\boxed{117^o}

20) x = 3,   y = 4,   r = 5

      \cos \theta=\dfrac{x}{r} \rightarrow \quad \cos \theta =\dfrac{3}{5} \rightarrow \quad \theta = cos^{-1}\bigg(\dfrac{3}{5}\bigg)\rightarrow \quad \theta = \large\boxed{53^o}

21) x = -\sqrt7,   y = -3,   r = 4

    \sin \theta=\dfrac{y}{r} \rightarrow \quad \sin \theta =\dfrac{-3}{4} \rightarrow \quad \theta = sin^{-1}\bigg(\dfrac{-3}{4}\bigg)\rightarrow \quad \theta = \large\boxed{229^o}    

22) x = -\sqrt{15},   y = 7,   r = 8

     \tan \theta=\dfrac{y}{x} \rightarrow \quad \tan \theta =\dfrac{7}{-\sqrt{15}} \rightarrow \quad \theta = tan^{-1}\bigg(\dfrac{7}{-\sqrt{15}}\bigg)\rightarrow \quad \theta = \large\boxed{119^o}

23) x = -13,   y = 6,   r = \sqrt{205}

     \tan \theta=\dfrac{y}{x} \rightarrow \quad \tan \theta =\dfrac{6}{-13} \rightarrow \quad \theta = tan^{-1}\bigg(\dfrac{6}{-13}\bigg)\rightarrow \quad \theta = \large\boxed{155^o}

24) x = 4,    y = -3,   r = 5

     \sin \theta=\dfrac{y}{r} \rightarrow \quad \sin \theta =\dfrac{-3}{5} \rightarrow \quad \theta = sin^{-1}\bigg(\dfrac{-3}{5}\bigg)\rightarrow \quad \theta = \large\boxed{323^o}

There are 16 rats in a cage. The ratio of white rats to all rats is 3:4. How many white rats are in the cage?
Y_Kistochka [10]

Answer:

There are 12 white rats in the cage.

Step-by-step explanation:

3 : 4   The question says there are 16 rats in the cage. Meaning that 16 is the

<u>x4 x4</u> total. Since 4(from the ratio)x4 is 16. You would multiply 4 on both sides.

12 : 16

Meaning there are 12 white rats to 16 total rats.

Find the area of the shaded regions:
katrin2010 [14]

area of Arc subtending 360^{\circ} (i.e. the whole circle) is $\pi r^2$

so area of Arc subtending $\theta^{\circ}$ is, $\frac{ \pi r^2}{360^{\circ}}\times \theta^{\circ}$

$\theta =72^{\circ}$ so the area enclosed by one such arc is $\frac{\pi (10)^272}{360}$

abd there are 2 such arcs, so double the area.
