Answer:t The volume of the box as a function of x is given by
Step-by-step explanation:
Since we have given that
Length of metal = 28 inch
Width of metal = 28 inch
Since squares are cut out of the four corners so that the sides can then be folded up to make a box.
Let the length of the sides of the squares that are cut out be 'x'.
So, Length of box would be
Width of the box would be
Height of the box would be x.
As we know the formula for "Volume of box":
Hence, the volume of the box as a function of x is given by
The inverse of the function f(x) = (3x)^2 is f-1(x) = 1/3√x
<h3>How to determine the inverse of the function?</h3>
The function is given as:
f(x) = (3x)^2
Remove the bracket in the above equation
So, we have:
f(x) = 9x^2
Express f(x) as y
So, we have
y = 9x^2
Swap the positions of x and y
So, we have
x = 9y^2
Make y the subject of the formula
y^2 = x/9
Take the square root of both sides
y = 1/3√x
Express as an inverse function
f-1(x) = 1/3√x
Hence, the inverse of the function f(x) = (3x)^2 is f-1(x) = 1/3√x

I thinks is B because the area of the base of the prism. Set the volumes equal. The volumes will only be equal when the radius of the cone is equal to.
