Using <span>Pythagorean theorem: c^2 = a^2 + b^2, and if a = 22 and b = 50
c^2=484+2500
c=sqrt 2984
c=55 meters</span>
        
                    
             
        
        
        
Answer:
w>-1
Step-by-step explanation:
1 Move terms 
53w-56w<16-13
2 Collect like terms then subtract
-3w< 3
3 Divide both sides by -3
Answer: w>-1

To find how many minutes of talk time is available per dolla, you have to divide 160 (number of minutes) by 40 (cost)
160/40 = 4
Therefore, it's 4 minutes per dollar
        
             
        
        
        
Y=x^3+5
y^-1=....
example >>a=x^3+5
 a-5=x^3
 3√a-5=x
y^-1=3√x-5
