Answer:

?=9

Step-by-step explanation:

We have a special right triangle, the 45-45-90 triangle.

In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.

Since we know that the side length is 9, this means that:

$x=9\\\text{Hypotenuse}=x\sqrt2\\\text{Hypotenuse}=9\sqrt2$

The ? is 9.

2 Select the correct answer. What is the inverse of function ? F(x)=10/9x+11 A.f-1(x)=9x-99/10 B.f-1(x)=9/10x+11 C.f-1(x)=9x+11/

Lilit [14]

Consider f(x)=y.

$\begin{gathered} f(x)=y \\ x=f^{-1}(y) \end{gathered}$

Simplify the equation f(x)=y to obtain the value of x in terms of y.

$\begin{gathered} f(x)=y \\ \frac{10}{9}x+11=y \\ \frac{10}{9}x=y-11 \\ 10x=9y-99 \\ x=\frac{9y-99}{10} \end{gathered}$

So inverse of function is,

$f^{-1}(x)=\frac{9y-99}{10}$

Correct nswer is A part.
