st Prep A new mobile device has a value of \( \$ 256.25 \). Its value changes by \( -22 \frac{1}{2} \% \) each year. What is the value of the phone after two years? \( \begin{array}{ll}\text { (A) } \$ 140.93 & \text { (C) } \$ 153.91 \\ \text { (B) } \$ 198.59 & \text { (D) } \$ 57.66\end{array} \)

4. Söz vermak, işara vermak, ad-san qazanr ifadələrindən hansılarında feil məcazi mən işlənib? (st. 2.1.2.)

The sum of the first two terms is \( 4 / 3 \) and the sum of terms 3 and 4 is 12 . Find the geometric progression. \( 3^{0}, 3^{1}, 3^{2} \) \( 3^{-1}, 3^{0}, 3^{1}, \ldots \ldots \) \( 3^{-2}, 3^{0}, 3^{1} \) \( 2 / 9,10 / 9,50 / 9, \ldots \). \( 1 / 9,11 / 9,11^{2} / 9, \ldots \ldots \)

Point A has coordinates \( (-13,-9) \) Point B has coordinates \( (1,15) \)

determine the evadrant in which the angles lies \( \begin{array}{ll}\text { a) } \frac{40 s^{\circ}}{} & \text { b) } \frac{\pi}{7}\end{array} \)

9) At which value of x the function \( f(x)=(x-2)(x-3)^{2} \) has a local \( \begin{array}{lllll}\text { maximum? } & \text { (A) } \frac{-7}{3} & \text { (B) } \frac{-5}{2} & \text { (C) }-3 & \text { (D) } \frac{7}{3}\end{array} \)
