Ok what was it then...I could answer it....well depends what type of question it is
Answer:
f(x) and its inverse are the same
Step-by-step explanation:
<u>The inverse function
</u>
If y=f(x), the inverse function 
is defined such as
To find the inverse function, there is a practical method:
a) Change letters x for y and vice-versa
b) Isolate y in terms of x only
c) 
In our case, 
a) Interchanging letters
b) Isolate 
c) 
As we can easily see, f and its inverse are exactly the same
Answer:
15 m
Step-by-step explanation:
you would use a sin equation because given the angle, the side you are resting to find is Opposite and the side you are given is the Hypotenuse
sin (32) = a/28
28 x sin (32) = a
14.83 = a
15 m = a when rounded
Answer:
No. The ladder is too steep.
Step-by-step explanation:
Length of ladder = 17 feet. This is the hypotenuse.
Side a of a right triangle = 16.6
To answer this, you need one of the trigonometric functions.
Opposite = 16.5
hypotenuse = 17
The function you need is the sine function.
Sin(theta) = opposite / hypotenuse
sin(theta) = 16.5 / 17
Sin(theta) = 0.97059
theta = sin-1(0.07059)
theta = 76.07
No the ladder is too steep.
