Answer:

y = $\sqrt{19^2 + 8.2^2}$

Step-by-step explanation:

to get the hypotenuse:

use the Pythagorean theorem:

a² + b² = c²

where a = 19, b = 8.2 c = y

plugin values:

19² + 8.2² = y²

y = $\sqrt{19^2 + 8.2^2}$

Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type the answer exactly in this f

WINSTONCH [101]

We can get the inverse function by first setting f(x) = y, solving for x, and after that switching y and x. So, let's solve for x:
$f(x)= \frac{1}{2}x+4$
$y= \frac{1}{2}x+4$
$2(y-4)=x$
$2x-4=y=f (x)^{-1}$

Then, just plug in 4 for x, and solve:
$2(4)-4= f (x)^{-1}$
$4=f (x)^{-1}$

There you have your answer.
