Answer:
k = 
Step-by-step explanation:
The equation of proportionality is
y = kx ← k is the constant of proportion
y =  x ← is in this form
 x ← is in this form
with k = 
 
        
             
        
        
        
S=r*theta where s is arc length and the r is radius and theta is in RADIANS ONLY!! If you use degrees this formula does not work. 
So we have a arc length of 38.485ft and a radius of 7. So rearranging the formula for theta, we get;
theta=(38.485)/(7)= 5.498radians then to convert to degrees if needed just take;
5.498rad*(180/pi)= 315deg

I think it’s 230+x is greater than or equal to 500.
I don’t have the greater than or equal sign in my phone lol
        
             
        
        
        
Area of the trapezoidal bucket, A is 130x² - 77x - 36 cm²
Step-by-step explanation:
- Step 1: Area of a trapezoid = 1/2 (Sum of parallel sides) × Height
Sum of parallel sides = (10x - 2) + (16x + 10) 
                                    = 26x + 8 = 2(13x + 4)
Height = 10x - 9
⇒ Area of the bucket = 1/2 × 2(13x + 4) (10x - 9)
                                     = (13x + 4)(10x - 9) cm²
                                     = 130x² - 117x + 40x - 36
                                 A = 130x² - 77x - 36
