Answer:
f^-1(x) = √(6/(9 -x))
Step-by-step explanation:
The inverse function is the solution to ...
x = f(y)
x = 9 -6/y^2
x +6/y^2 = 9 . . . . . add 6/y^2
6/y^2 = 9 -x . . . . . subtract x
6/(9 -x) = y^2 . . . . . multiply by y^2/(9 -x)
y = √(6/(9 -x)) . . . . take the square root
Then the inverse function can be written as ...
f^-1(x) = √(6/(9 -x)) . . . . . . x < 9
Answer:
The product of
is 81.6
Step-by-step explanation:
Given : 
To Find : Find the product
Solution:


So, 

Hence the product of
is 81.6
2(6*8)=96
2(6*3)=36
2(8*3)=48
96+36+48= 180 sq. in.
(The above is the answer to #2).I shouldn't give the answer to all of them, but I can explain how to do it. In order to calculate surface area, you need to find the area for all sides of the shape. For example, #2 has six sides, so you need to find the area for all six of those sides. There are two sides that are 8 x 3, two sides that are 6 x 8, and two sides that are 6 x 3. Therefore, your equation would be 2(8x3) + 2(6x3) + 2(6x8). From that you get 48+36+96 = 180 square inches (sq. in.)
12,50,000cm
Step-by-step explanation:
Given that 1cm=500000cm
Then using unitary law, we get
Actual distance=2.5cm=2.5×500000=12,50,000cm
