The population of hawks in Elk Island National Park can be modeled by the sinusoidal curve \( H=51 \sin (0.63 x+5.9)+76 \), where \( H \) represents the number of hawks and \( x \) represents time in years since 2005. 26. What is the minimum amount of hawks in Elk Island? ( 1 mark) In which year does the first minimum number of hawks occur (after 2005)? ( 1 mark) To the nearest tenth of a year, how many years is the population of the hawks below 50 in the first period? ( 1 mark)

25. \( A B C D \) параллелограммнинг иккита қўшни томони \( \overrightarrow{A B}=\vec{a}, \overrightarrow{A D}=\vec{b} \), диагоналларининг кесишиш нуқтаси эса \( \vec{M} \) бӱлса, \( \overrightarrow{M A}, \overrightarrow{M B}, \overrightarrow{M C}, \overrightarrow{M D} \) векторларни \( \vec{a} \) ва \( \vec{b} \) векторлар орқали ифодаланг.

b) \( \log _{\frac{2}{3}}(x-2)>1 \)

For the number -3 , give the following: A.) The opposite of \( -3=\square \) B.) The reciprocal of \( -3=\square \) C.) The absolute value of \( -3=\square \)

The one-to-one functions \( g \) and \( h \) are defined as follows. \[ \begin{array}{c}g(x)=\frac{x-9}{11} \\ h=\{(-8,6),(0,3),(1,0),(5,8),(8,7)\} \\ g^{-1}(x)=\square \\ \left(g \circ g^{-1}\right)(-1)=\square\end{array} \] Find the following.

Find the zeros of the function, and their multiplicities. \[ f(x)=x^{3}+21 x^{2}-x-21 \]
