Answer:

Step-by-step explanation:
Given: Perimeter of base of a pyramid = 12.8 m
Height of the pyramid = 12.5 m
To find: volume of a pyramid
Solution:
Perimeter of base of a pyramid = 12.8 m
As base of the pyramid is a square,
12.8 = 
side of a square = 
Area of a square (A) = 
Height of the pyramid (h) = 12.5 m
Volume of the pyramid =

Step-by-step explanation:
Answer:
Inverse of f(x)

Step-by-step explanation:
<u> Explanation</u>:-
<u>Step(i)</u>:-
Given the function

Given function is one-one and onto function
Hence f(x) is bijection function

now cross multiplication, we get
( 8+x)y = 3 x
8 y + x y = 3 x
8 y = 3 x - x y
taking Common 'x' we get
x (3 - y) = 8 y

<u><em>Step(ii)</em></u>:-
The inverse function

The inverse function of x

<u><em>Final answer</em></u>:-
Inverse of f(x)
