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>

Step-by-step explanation:
tan C = opp/adj
For angle C, the opposite leg is 27,a nd the adjacent leg is 36.
tan C = 27/36
Answer: 27/36
It’s 32 the answer is the square root of 32
Answer:
The value of x increased by 3.25.
Step-by-step explanation:
It is given that the value of x varies from x=2 to x=5.25.
We need to find the change is x.
If value of a variable x varies from a to b, then the change in te value of variable is
Change in x = b - a
For the given problem the variable is x, a=2 and b=5.25.
Change in x = 5.25 - 2
= 3.25
If the change is positive, then the value of variable increased and if the change is negative, then the value of variable decreased.
Therefore, the value of x increased by 3.25.
