First find the length of the hypotenuse using pythagorean theorem
<span>c^2 = 5^2 + 7^2
c^2 = 25 + 49
c^2 = 64
c=8 (take the square root in both sides)
Since sin = opposite/hypotenuse,
sin = 5/8 = 0.625</span>

Answer:
B
Step-by-step explanation:
We are given the function:

And we want to determine the value of:

Let this value equal <em>a</em>. In other words:

Then by the definition of inverse functions:

Hence:

Solve for <em>a: </em>

By the Zero Product Property:

Hence:

Thus, f(9) = 225. Consequently, f⁻¹(225) = 9.
In conclusion, our answer is B.
