Answer:
$7.65
Step-by-step explanation:
step one:
The total bill was $45.
michelle pays 35% of the total bill 
= 35/100*45
=0.35*45
=$15.75
lori pays 48% of the bill 
= 48/100*45
=0.48*45
=$21.6
Therefore patti will pay
=45-15.75-21.6
=$7.65
 
        
                    
             
        
        
        
Y=-x^2 is non linear due to the x being squared

Answer:
The answer to your question is: the first option  - 9/ 
Step-by-step explanation:
Process
           cosФ = adjacent side / hypotenuse
           -1/9 = adjacent side / hypotenuse
           adjacent side = -1    hypotenuse = 9
           c² = a² + b²
           b² = c² - a²
            b² = 81 - 1
            b =  b = opposite side
    b = opposite side
But b is negative because we are in the third quadrant.
           b = -
Finally   csc Ф = hypotenuse / opposite side
              csc Ф = - 9 /
