It costs \( \$ 8 \) to rent a bicycle for the first hour. It costs \( \$ 5 \) for each odditional hour. Which expression can be used to determine the total cost of renting a bicycle for any number of hours, \( h \) greater than 1 ? \( \begin{array}{ll}\text { (A) } h \times(h+5) \\ \text { (i) } 5+8 h \\ \text { (c) } h \times(h+8) \\ \text { (D) } 8+5 h\end{array} \)

Resuelva las siguientes operaciones con número racionales. \( \left(-\frac{3}{5}\right)\left(\frac{4}{7}\right)\left(-\frac{1}{6}\right) \) \( \left(-\frac{11}{7}\right)\left(-\frac{5}{9}\right)\left(-\frac{15}{6}\right) \) \( \left(-\frac{2}{5}\right)\left(-\frac{45}{2}\right) \) - \( (-7)\left(-\frac{5}{8}\right)\left(-\frac{9}{7}\right) \) - \( \left(-\frac{4}{5} \div-\frac{3}{4}\right. \) \( \frac{9}{8} \div \frac{7}{5} \)

The temperature of a person during a certain illness is given by the following equation, where \( T \) is the temperature \( \left({ }^{\circ} \mathrm{F}\right) \) at time \( t \), in days. Find the relative extreme points and sketch a graph of the function. \( T(t)=-03 t^{2}+24 t+983,0 \leq t \leq 8 \)
