I think that you are mistaking the memory tool for something else
or a math book is trying to make math cute by calling them 'socatoa joe' and 'mr. pi' and such
anyway, SOH, CAH, TOA is the way to remember
Sine=oposite/hypotonuse
Cosine=adjacent/hypotonuse
Tangent=oposite/adjacent
(oposite side=side oposite the angle
adjacent is the side touching the angle that is not they hypotonuse
and of course the hypotonuse is the longest side aka, side oposite right angle)
        
             
        
        
        
Answer:
Step-by-step explanation:
(-3/4)x + 9 = (-1/2)x + 8
         9 - 8 =  (-1/2)x + (3/4)x
                1 =  (1/4)x
                x = 4
y = (-3/4)4 + 9
y = -3 + 9
y = 6
 
        
             
        
        
        
Answer:
Translation 2 units downward
Step-by-step explanation:
If we start with the graph of f(x) = 3x + 8 and translate it 2 units downward, we'll end up with the graph of g(x) = 3x + 6.  Note:  8 - 2 = 6.
 
        
                    
             
        
        
        
I think it’s 2/7=8/28 1/4=7/28
        
             
        
        
        
Area= 2πr
So, 
If you were to multiply the radius by 2 since 2 is not in the equations, 
4*2= 8
8π ft^2 would be the correct answer.
I hope this helps!
