i) Para preparar una pintura de color gris se mezclaron \( 9,8 \mathrm{~L} \) de pintura negra y \( 5,3 \mathrm{~L} \) de pintura blanca. Si se quiere obtener el mismo tono de gris pero con 6 L de pintura blanca. ¿Cuántos de la otra hacen falta? ¿Y si se usan 5 L de pintura negra, cuántos litros de la blanca son necesarios?

Suppose that the functions \( u \) and \( w \) are defined as follows. \[ \begin{array}{l}u(x)=x^{2}+5 \\ w(x)=\sqrt{x+3} \\ \text { Find the following. } \\ (w \circ w)(1)=\square)(1)=\square\end{array} \] \( (w \circ u) \)

The animals at a safari park include camels, kangaroos and meerkats. There are 12 more kangaroos than there are camels. There are 3 times as many meerkats as there are camels. There are the same number of kangaroos as there are meerkats. How many camels are there at the safari park?

17) Suppose the function \( f(t) \) has a global maximum value of 5 when \( t=-1 \). What is the largest value that \( G(w)=3 \cdot \ln (f(w))+8 \) will ever have, and where does it occur?
