Answer:
Step-by-step explanation:
In order to find the inverse of a function, we need to follow a couple of steps.
- Step 1: Write the function as
- Step 2: Swap all x and y values
- Step 3: Solve for y
- Step 4: Replace y with
We can follow these steps to find the inverse of this function.
Step 1: We can just replace the f(x) with y, making our function 
.
Step 2: We can swap where the x and y values are, making our equation
Step 3: We can now solve for y.
We now have the function as 
.
Step 4: We can now replace the y with .
Therefore the inverse of 
is .

Answer:
23.20°
Step-by-step explanation:
All three sides of this right triangle are given, so the acute angle of interest can be found using any of the inverse trig functions.
<h3>Trig relation</h3>
The tangent of the angle is the ratio of opposite and adjacent sides:
Tan = Opposite/Adjacent
Here, that means ...
tan(α) = 3/7
To find the value of α, we need to use the inverse tangent function, also called the arctangent function.
α = arctan(3/7) ≈ 23.19859°
α≈ 23.20°
The answer would be: Samatha because you need 5 gallons and 4/10 of a gallon more.
