6 Dados los subconjuntos \( R_{1}, R_{2} \) de \( \mathbb{R}^{3} \), de- finidos como \( R_{1}=\{\vec{x}=t(4,5,-1) \mid t \in \mathbb{R}\} \) \( R_{2}=\left\{\left.\vec{x}=s\left(-1,-\frac{5}{4}, \frac{1}{4}\right) \right\rvert\, s \in \mathbb{R}\right\} \) Prueba que \( R_{1}, R_{2} \) representan la misma recta \( R \), es decir, \( R_{1}=R_{2} \)

The depth d that a sphere of radius \( r \) would need to be filled to be \( p \) percent filled can be calculated using the formula \( -d^{3}+3 r d^{2}=4 p r^{3} \) What would the depth need to be if the sphere has a radius of 2 feet and you want the sphere to be 80 percent full? Substitute your percentage as a decimal in for \( p \). Type your answer to the nearest hundredth of a foot. Give your answer to two decimal places.

a) Valentina tiene que recorrer 1400 kilómetros dando vueltas a una pista atletismo de 200 metros. Si lleva 3 vueltas, ¿Cuántos metros le quedan?

a. \( \frac{33}{16} \cdot \frac{40}{6}: \frac{65}{4}= \)

b. \( \frac{45}{50}: \frac{63}{105} \cdot \frac{25}{15}= \)
