The function
... f(x) = (x+2)/(x-1) = 1 + 3/(x-1)
is symmetrical about the line y=x, hence is its own inverse.
We can evaluate the desired derivative directly.
... f'(x) -3/(x-1)²
so f'(2) is
... f'(2) = -3/(2-1)²
The expressions simplified in the exact form would be 1/512.
Answer:
7 1/5 m
Step-by-step explanation:
Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3
Volume of a rectangular prism = Length × Width × Height
Length = Volume/ Width × Height
Length = 60 m³/2 1/2 m × 3 1/3 m
Length = 60 m³/8 1/3 m²
Length = 60 m³÷ 8 1/3 m²
= 60 m³ ÷ 25/3 m²
=( 60 × 3/25 )m
= 180/25 m
Length = 7 1/5 m
