Answer:

la derivada de la función vectorial dada es = ( -16-22t, 14-36t, -2-16t )

Explicación paso a paso:

datos proporcionados:

función vectorial: r(t) = ta*(b+tc)

a = ( 2,-3.4).   b = (-4,5,-1).  c = ( -2,-1,5)

para determinar la derivada de la función vectorial, se procederá a diferenciar respecto a x; aquí está la solución detallada

Two boats start their journey from the same point A and travel along directions AC and AD, as shown below: ABC is a right triang
Inessa [12570]

*Refer to the image attached below

Answer:

346.4 ft

Step-by-step Explanation:

The distance between the boats, CD = BD - BC

Using trigonometry, find the length of BD in triangle ∆ABD and also calculate the length of BC in triangle ABC.

Length of BD in triangle ABD:

Opposite side to <30° = 300 ft

Adjacent side = BD

tan(30) = \frac{300}{BD}

BD*tan(30) = 300

Divide both sides by tan(30)

\frac{BD*tan(30)}{tan(30)} = \frac{300}{tan(30)}

BD = 519.6 ft (rounded to nearest tenth)

Length of BC in triangle ABC:

Opposite side to <60° = 300 ft

Adjacent side = BC

tan(60) = \frac{300}{BC}

BC*tan(60) = 300

Divide both sides by tan(60)

\frac{BC*tan(60)}{tan(60)} = \frac{300}{tan(60)}

BC = 173.2 ft (rounded to nearest tenth)

The distance, CD, between the boats is calculated as BD - BC

= 519.6 - 173.2 = 346.4 ft
