11 A quadratic model gives the predicted instantaneous rate of change, in bacteria per hour, of a bacteria population as a function o[ the population size. According to the model, the predicted instantaneous rate of change is 0 bacteria per hour for a population size of 0 , and the maximum prenticted instantaneous rate of change is 0.200 bacteria per hour for a population size of 7,000 . Based on this model, what is the predicted instantaneous rate of change, in bacteria per hour, of the bacteria population for a population size af 700 ?

\( A B C, m(\angle C)=60^{\circ}, m(\angle B)=90^{\circ} \) and \( \bar{A} \mathrm{AC}=8 \mathrm{~cm} \)., then \( B C=\ldots \ldots \mathrm{cm} \). the opposite figure :
