Answer:
f'(x) = 
Step-by-step explanation:
i) f(x) = 9 / x
ii) f'(x) = 

What we know:
3.14 pi
radius: 7in.
Result units: in^3, this is the results of in used for radius; no conversion needed
Formula volume of a sphere: (4/3)* pi * r^3
(4/3)(3.14)(7)(7)(7)
(4/3)(3.14)(343)
(4/3)(1077.02)
(1.3)(1077.02) \\repeated 3 infinite
1436.026666\\repeated 6inf
The volume of the sphere is about 1436.0266 in^3
The perimeter of a rectangle is P=2l+2w where l is the length and w is the width.
Plug in values of l and w in:
P=2(x+8)+2(x-1)
P=2x+16+2x-2
P=4x+14
So the perimeter of the rectangle is 4x+14 units
Hope this helped!
