Answer:
   y = -2.5
Step-by-step explanation:
For such a problem as this, you can replace all sine or cosine functions with their midline value of 0. Then you have ...
   f(x) = 0 -2.5
which simplifies to ...
   f(x) = -2.5
You can leave the equation like this, or write it as ...
   y = -2.5
_____
Perhaps you can see that the midline is the value of any constant added to a sine or cosine function.

Answer:
  (x - 8)^2 + y^2 = 3.
Step-by-step explanation:
(x - h)^2 + (y - k)^2 = r^2
Here h = 8, k = 0 and r^2 = (√3)^2 = 3
The answer is  (x - 8)^2 + (y - 0)^2 = 3
or (x - 8)^2 + y^2 = 3.
 
        
             
        
        
        
<u>Answer:</u>
<h3>( 

 ) x ( 

 ) </h3>
<u>Step-by-step explanation:</u>
To find the area of a rectangle, we have to multiply the length with the width.
In the question, the given length is 'x' and the width given is 'x +7'
So, the area would be 
(  ) x (
 ) x (  )
 ) 
The area = 
So, the equation to find the area of such a rectangle would be:-
(  ) x (
 ) x (  )
