Use the slope formula:
(y2 - y1)/(x2 - x1)
(x1, y1) = (-5, 1)
(x2, y2) = (-4, -4)
        
             
        
        
        
Answer:  5 cos x
<u>Step-by-step explanation:</u>
y = sin x     is       y = cos x        shifted to the right π/2 units.
y = 5 sin (x + π/2)     is a shift to the left π/2 units (which results in cos x) and    .                                 an amplitude of 5.
--> y = 5 cos x
 
        
             
        
        
        
Angle R= 36°
180-68-76=36°
        
             
        
        
        
Step-by-step explanation:
logx√2=1/6
<=> logx(2^1/2)=1/6
<=>1/2.logx(2)=1/6
<=>logx(2)=1/3
<=>2=x^1/3
<=>x=
Sorry I forgot the formula in the last step
