Answer:
Jackson spent $4.25 on his lunch
Step-by-step explanation:
 because $6.50- $2.25 is $4.25
 
        
                    
             
        
        
        
Well 2.4/ 16.4 is 6.9, but idk if that is what u were asking for
        
             
        
        
        
<u>Answer-</u> Length of the curve of intersection is 13.5191 sq.units
<u>Solution-</u>
As the equation of the cylinder is in rectangular for, so we have to convert it into parametric form with 
x = cos t, y = 2 sin t   (∵ 4x² + y² = 4 ⇒ 4cos²t + 4sin²t = 4, then it will satisfy the equation)
Then, substituting these values in the plane equation to get the z parameter,
cos t + 2sin t + z = 2
⇒ z = 2 - cos t - 2sin t
∴ 
   
   
As it is a full revolution around the original cylinder is from 0 to 2π, so we have to integrate from 0 to 2π
∴ Arc length



Now evaluating the integral using calculator,
