On his fishing trip Justin rides on hist 12 km south. The fish aren't biting so he changes location and goes 4 km west. What is
Sati [7]

Answer:

Justin's displacement is 12.65 km.

Step-by-step explanation:

Since Justin rides 12 km south, then 4 km west, his displacement can be determined by applying Pythagoras theorem to the sketch of his journey. Let his displacement be represented by s,

/Hyp/^{2} = /Adj1/^{2} + /Adj2/^{2}

s^{2} = /4/^{2} + /12/^{2}

   = 16 + 144

s^{2}  = 160

⇒ s = \sqrt{160}

      = 12.6491

s ≅ 12.65 km

Justin's displacement is 12.65 km.

Solve the equation sin theta = 0.3 to the nearest tenth. Use the restrictions 90degrees &lt; theta &lt; 180degrees.
Alexxandr [17]
We first do:
∅ = sin⁻¹(0.3)
∅ = 17.5°

To go into the second quadrant, we add 90°.
∅ = 17.5 + 90
= 107.5°
The answer is A.
