Answer:
each side is 31cm
Step-by-step explanation:
91/3=31
31+31+31=93
The equation that is given in this item can be mathematically expressed as,
f(x) = (x/7)^(1/3) - 9
The expression f(x) can be replaced with y such that the equation can also be written as,
y = (x/7)^(1/3) - 9
The first thing that needs to be done to get the inverse of the function is to interchange the positions of x and y. In this equation, that becomes,
x = (y/7)^(1/3) - 9
Then, solve for the value of y in terms of x.
Transpose the constant to the other side of the equation.
x + 9 = (y/7)^(1/3)
Raise the whole equation by 3 in order to eliminate the radical.
(x+9)³ = (y/7)
Multiply the equation by 7 to eliminate the fraction.
(x+9)³(7) = y
Thus, the inverse of the function is equal to
<em> f⁻¹(x) = 7(x+9)³
</em><em />The answer is letter B.<em>
