\( \Rightarrow \) If \( a=5 \), find the value of \( \frac{16}{2^{a}} \)

What is the common ratio in the following geometric sequence? \( 2, \frac{1}{2}, \frac{1}{8}, \frac{1}{32}, \ldots \) (1 point) 0.1 .5 \( \frac{1}{2} \) - \( \frac{1}{4} \)

Value: 2 The graph of the quadratic function given by the equation \( f(x)=-\frac{1}{2}(x-1)^{2} \) will fip upside down because there is a negative sign in front. True False

Exercice 2 : Déterminer la valeur du produit \( P \) tel que : \[ P=\left(1-\frac{1}{2}\right) \times\left(1-\frac{1}{3}\right) \times\left(1-\frac{1}{4}\right) \times\left(1-\frac{1}{5}\right) \times \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots\left(1-\frac{1}{99}\right) \times\left(1-\frac{1}{100}\right) \]

e) \( 5^{\log _{25} 0,25} \);
