Answer:
1
Step-by-step explanation:
If you are just looking for the derivative, then all you need to use the power rule for this. Technically the x in (x-9) has a power to the 1, so really x^1-9. To use power rule, you bring down the exponent, in this case, 1, and then minus 1 from what the exponent was. 
1x^(1-1) = 1x^0. The derivative of any constant is 0, so don't even worry about the -9. We know that anything raised to the zero is just 1, so in this case your answer is 1. 
Hope this helps :)

Answer:
20
Step-by-step explanation:
I assume y is 4/3 of z.
x = 7/6 y
y = 48
x = 7/6 * 48
x = 7 * 8
x = 56
y = 4/3 z
4/3 z = y
z = 3/4 y
z = 3/4 * 48
z = 36
x - z = 56 - 36 = 20
 
        
             
        
        
        
Surface area is the area of the surfaces
the areas are
base
2 triangles (faces)
2 rectangluar sides
solve
area of base=legnth times width=16 times 9=144
area of 2 triangles is 2 times 1/2 times base times height=2 times 1/2 times 16 times 6=1 times 16 times 6=96
area of 2 rectangles=2 times legnth times width=2 times 10 times 9=180
total area=base+2 triangles+2 rectangles
total area=144+96+180=420 square inches
the answer is 420 square inches or B
