When snall amounts of deaning additives (detergent products) are added to wizter in order to faciltate the washing of tanks which previously cortained liquid chemicals, must be ensured that:

on the basis of VSEPR theory \( \mathrm{SO}_{2} \) is a: \( \begin{array}{ll}\text { a) Linear molecule } & \text { b) } A \text { bent molecule } \\ \text { c) } A \text { strong molecule } & \text { d) } A \text { gaseous molec }\end{array} \)

Sadve far \( \log _{\frac{1}{2}} \log _{7} x \)

\( \left. \begin{array} { l } { | - 15 | + V ^ { 2 } - 35 , V = 6 } \\ { 4 Y \div 16 - | - 48 | \div 2 Y , Y = - 8 } \end{array} \right. \)

Determine the future value of an annuity after ten monthly payments of R600,00 at an interest rate of \( 12 \% \) per annum, compounded monthly.

When his son was three years old, Vuyisanani made a deposit of R16 200,00 in the bank. The investment grew at a simple interest rate and, when Vuyisanani's son was 22 years old, the value of the investment was R46 980,00 . Had the interest been \( 1,25 \% \) less, how much interest would he have accumulated in the 19 years?
