This is a right triangle. We know that

                                                 \tan x = \frac{\text{opposite side}}{\text{adjacent side}}

Therefore,

                                              \tan x = \frac{18}{21} = \frac{6}{7} = 0.857

Now we have:

                                                 x=\tan^{-1}0.86

                                                       x=40.6

If (fx)=5x, what is f^-1(x)
zysi [14]

Answer:

x/5

Step-by-step explanation:

To get the inverse function you need to leave the x alone and then switch variables ( f(x) = y)

f(x) = 5x

y = 5x

y/5 = x

Now that x is alone you switch the x for y and the y for x and you get:

x/5 = y

And this new y is the inverse function of f(x) ( f^-1(x))

f^-1(x) = x/5

A number subtracted from -50 amounts to 171 what is the equation
shtirl [24]
-50 - (-221) = 171

This is because subtracting a negative number is like adding a positive version of that instead. For a more simple example:
5 - (-2) = 7 or 5 + 2 = 7
