En una receta para 6 personas se necesitan 240 g de salmón. Averigua lo que necesito para 8 personas.

\( \therefore 3 ) y = \frac { 1 } { x ^ { 2 } } + \frac { 3 } { x ^ { 3 } } - \frac { 2 } { x } + 4 \)

Use the product rule to simplify the expression. \( z \cdot z^{6} \cdot z^{7} \)

In die volgende reaksies (i) gebruik die oksidasiegetalle om te bepaal wat geoksideer is en wat gereduseer is (ii) skryf halfreaksies om elke proses te wys (iii) balanseer die vergelyking (iv) identifiseer die oksideer-en reduseermiddels 1. \( \mathrm{Zn}+\mathrm{H}_{2} \mathrm{SO}_{4} \longrightarrow \mathrm{ZnSO}_{4}+\mathrm{H}_{2} \) 2. \( \mathrm{HgO} \longrightarrow \mathrm{Hg}_{2}+\mathrm{O}_{2} \) 3. \( \mathrm{Ca}+\mathrm{Cl}_{2} \longrightarrow \mathrm{CaCl}_{2} \) 4. \( \mathrm{NaCl} \mathrm{Na}+\mathrm{Cl}_{2} \)

Of the 1,250 people who were surveyed, only \( 30 \% \) said the longtime city councilman should not run for mayor. How many of those surveyed thought the councilman should not run for mayor?

\( \lim _ { x \rightarrow \lim ^ { 2 / 3 } } \frac { 5 x ^ { 2 } + 3 } { x } \)
