Answer:
yes, that is the correct answer. X is domain and Y is range so you are correct.
Step-by-step explanation:
<h3><u>Ⲁⲛ⳽ⲱⲉⲅ:</u></h3>
- <u>▶( x - 3 ) ( 3x - 6 )</u>
<h3><u>Ⲋⲟⳑⳙⲧⳕⲟⲛ :</u></h3>
ㅤㅤㅤ➙ 3x² - 15x + 18
ㅤㅤㅤ➙ 3x² - 9x - 6x + 18
ㅤㅤㅤ➙ 3x ( x - 3 ) + 6 ( - x + 3 )
ㅤㅤㅤ➙ 3x ( x - 3 ) - 6 ( x - 3 )
ㅤㅤㅤ➙ <u>( x - 3 ) ( 3x - 6 )</u>
The angle between their paths to the nearest degree is 68⁰.
<h3>
Displacement of each boats after 45 minutes</h3>
first displacement, a = 15 km/h x (45/60)
first displacement, a = 11.25 km
second displacement, b = 18 km/h x (45/60)
b = 13.5 km
<h3> Angle between their paths to the nearest degree</h3>
c² = a² + b² - 2ab(cosθ)
2ab(cosθ) = a² + b² - c²
cosθ = (a² + b² - c²)/(2ab)
cosθ = (11.25² + 13.5² - 14²) / (2 x 11.25 x 13.5)
cosθ = 0.371
θ = arc cos(0.371)
θ = 68.22 ⁰
Thus, the angle between their paths to the nearest degree is 68⁰.
