Q:
A population of bacteria is growing according to the equation \( P(t)=1250 e^{0.17 t} \), where \( t \) is the number
of hours. Estimate when the population will exceed 2266 . Give your answer accurate to one decimal place.
\( t=\square \) hours

Q:
1) En utilisant le raisonnement par contraposée montrer que :
\[ \forall(x, y) \in \mathbb{R}^{*} ;\left(x \neq y \text { et } x y \neq 1 \Rightarrow \frac{x}{x^{2}+1} \neq \frac{y}{y^{2}+1}\right) \]
Q:
Starting with the graph of \( f(x)=2^{x} \), write the equattion of the graph that results when:
(a) \( f(x) \) is shifted 3 units upward. \( y=\square \)
(b) \( f(x) \) is shifted 8 units to the right. \( y=\square \)
(c) \( f(x) \) is reflected about the \( x \)-axis and the \( y \)-axis. \( y=\square \)

22. On considère la suite \( \left(u_{n}\right) \) définie pour tout
\( n \in \mathbb{N} \) par \( u_{0}=10 \) et \( u_{n+1}=\frac{1}{4} u_{n}+6 \).
1. Conjecturer à la calculatrice le sens de variation de
la suite \( \left(u_{n}\right) \).
2. Prouver par récurrence que \( u_{n} \geqslant 8 \) pour tout \( n \in \mathbb{N} \).
3. En déduire sur le sens de variation de la suite \( \left(u_{n}\right) \).
4. La suite \( \left(u_{n}\right) \) est-elle convergente?
