Answer:
interchange the role of x and y
x=9y+5
x-5=9y
<u>x-5</u><u> </u>=y
9
so,f^-1(x)= <u>x-5</u>
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>9

Step-by-step explanation:
<h3>
Answer: 3/5</h3>
Explanation:
For angle A, the side furthest from here is BC = 15. This is the opposite side for this reference angle.
The hypotenuse is AC = 25, which is the longest side of any right triangle (always opposite the 90 degree angle).
The sine ratio involves dividing the opposite over hypotenuse.
So,
sin(angle) = opposite/hypotenuse
sin(A) = BC/AC
sin(A) = 15/25
sin(A) = (3*5)/(5*5)
sin(A) = 3/5
