Answer:
The equation of the displacement  as a function of time
 as a function of time  is :
 is : 

Step-by-step explanation:
Generally , A simple harmonic wave is a sinusoidal function that is it can be expressed in simple  or
 or  terms.
 terms.
Thus,

is the general form of displacement of a SHM.
where,
- <em> is the displacement with respect to the mean position at any time is the displacement with respect to the mean position at any time </em> </em>
- <em> is amplitude </em> is amplitude </em>
- <em> is the natural frequency of oscillation ( is the natural frequency of oscillation ( )</em> )</em>
- <em> is the phase angle which indicates the initial position of the object in SHM ( is the phase angle which indicates the initial position of the object in SHM ( )</em> )</em>
given,
- Time period ( ) = ) = 
 
- The natural frequency ( ) and time period ( ) and time period ( ) is : ) is :
                                
∴
 =
 =  
 
∴
the equation :
<em>⇒ </em>                     ------1

since  when
 when  ,
 ,
<em>⇒ ------2</em>
                         ------2</em>
where n is an integer ;
<u>⇒since the bouy immediately moves in the negative direction ,  must be negative or c must be an odd multiple of

<em>⇒  ------3</em>
         ------3</em>
where k is also an integer ;
the least value of  ;
;
thus ,
the equation is :

Answer:
2x*x
2x*-5
1*x
1*-5
2x²-10x+x-10 add numbers that have similar variables
-2x²-10x+x-10
=[-2x²-9x-10]
 
        
             
        
        
        
7/8 / 11/12. First get the reciprocal of 11/12 (which is 12/11). Then multiply by the reciprocal. 7/8 * 12/11 = 84/88
don't forget to simplify
21/22
